The Concept of ‘Roadmapping Service’: Exploring Customer Perspectives of Roadmapping through the Service Lens
Authors: Oliveira Maicon Gouvea , Routley Michele , Phaal Robert , Mendes Glauco Henrique Sousa
Published: July 2019

Roadmapping has been addressed as a management approach used to support strategic and innovation planning of organisations over recent decades. This paper introduces a new standpoint for addressing roadmapping through the application of service theories as a way for tackling the demand for the digitalisation of roadmapping. To this end, the concept of roadmapping as a service offer is developed and employed to analyse three customer perspectives of roadmapping: owners and sponsors, team members, and facilitators. Based on a literature review and interviews with roadmapping experts, customer jobs, pains, and gains are described for each of the perspectives. In the end, the paper provides insights for the understanding of the concept of roadmapping service and opens opportunities for further theoretical and empirical developments around this new path. These results are part of a broader research project exploring the digitalisation of roadmapping.
Who are the Stakeholders Mentioned in Cases of Product-Service System (PSS) Design?
Authors: da Costa Fernandes Sânia , Martins Luiza Diegues , Rozenfeld Henrique
Published: July 2019

Product-service systems (PSS) are solutions that integrate product and services in order to fulfill the customers’ needs by means of greater value in use. Multiple stakeholders should be involved in the design process for the development of a successful PSS value proposition. However, it is not clear who could be the potential stakeholders of a PSS. The aims of this study are to consolidate the stakeholders cited in PSS case studies and to reveal the terms used to refer to “stakeholder” in PSS literature. A systematic literature review was carried out, and an inductive content analysis procedure was applied. A total of 28 stakeholders were listed from the selected studies, whose PSS cases were classified as use- oriented or result-oriented services. Multiple terminologies are used to refer to stakeholders. This study contributes for showing the potential stakeholders that can be involved and engaged in the PSS design and operation. Also, it indicates the terms from which they can be addressed in the PSS literature.
Design Against the Plastic Soup - The Effect of Small Product Designs in Sustainable Design Education
Authors: Du Bois Els , Van Gogh Dirk , Veelaert Lore , Van Doorsselaer Karine
Published: July 2019

Plastics are ubiquitous in our daily life due to their versatile characteristics, however, these excellent characteristics also contributed to the emergence of a gigantic garbage of floating plastics in our ocean, called the plastic soup. Within this research project we investigated the opportunities by design to cope with this wicked problem. The hypothesis is that picking small opportunities in a wicked problem can have a large impact on the related ecosystem. In addition, we also wanted to investigate how design students would deal with the problem to create larger awareness of the designers' impact and responsibility. Although there is no ideal answer to a systemic problem such as the plastic soup, intervening on systems is possible. As the characteristics of a product directly influence the way the entire value chain works, designers have a large responsibility / opportunity to influence the system. An experiment was executed with 69 design students to explore the opportunities. The resulting design concepts were discussed by experts, reasoning towards relationships, needs to elaborate the design practices, and ecodesign education in a circular economy.
Design Contributions to Building Technology: Goals, Interfaces and Responsiveness
Authors: Boess Stella U.
Published: July 2019

In this paper, I identify issues that arose in a recent pilot project in which designers contributed to the construction field. The project was led by an overall responsible innovation goal for sustainability impact: contribute to global CO2 reduction. The innovation solution being developed to achieve this goal was a sustainable renovation concept intended for upscaling. In this pilot project, it was applied to a social housing block of 12 apartments. The designers sought to help align technical solutions with the residents’ later use of their homes, because the latter is an important factor in achieving a zero-energy outcome. The paper identifies four issues that arose in the collaboration between design and construction and installation professionals. The issues are goal translation, goal dissipation, the contested service interface and the contested responsiveness to residents. I argue that designers can engage and contribute through design intervention and applying care in the collaboration, in order to support the success of responsible innovation.
Design Requirements to Educate and Facilitate Junior Design Professionals to Reflect more Effectively on Critical Situations and Conflicts at Work
Authors: van Onselen Lenny , De Lille Christine , Snelders Dirk
Published: July 2019

Junior designers are not trained to cope with critical situations and conflict at work. Most design schools do not educate their design students to prepare them for (potential) conflict. As a result, junior designers often do not have conflict-handling skills to handle critical situations and conflicts. While some tools and methods exist to help them make responsible design choices, these often address value differences underlying (potential) conflict without taking the perspective of the designer, and thus without supporting young designers to start by reflecting on their own intrinsic values.

The aim of this study is to find a way to help junior designers to reflect effectively on critical situations, thereby improving their conflict-handling skills. Data was collected through four steps in an action research. Researchers collaborated with an identity programme for junior design professionals. Insights from try-outs and small interventions were transferred into design requirements for an approach to educate and facilitate junior design professionals to reflect more effectively on critical situations.
Eco-Innovation in Biomass Research Projects
Authors: Yannou-Le Bris Gwenola , Treves Viviane , Meynard Jean-Marc , Cerf Marianne
Published: July 2019

This paper tackles two questions. Our first question addresses the multi-actor activity that is visibly required for building radical innovations like eco-innovation. Our second question addresses the tricky issue of how to assess contribution to ecological transition when innovation projects are still in the fuzzy early-upstream phase. In this aim four research projects are selected and analyzed in this paper because they share a common scope—the development of new processes or materials tied to the conversion of biomass. Through the analysis of the actors interactions conducted in these projects, of their perimeters, of their sustainability objectives and of their results we show a limit of the eco-innovation capacity of these projects linked to the limits of their crossdisciplinarity.
Exploratory Study of the Integration of Frugal Innovation in the Design of Products for the BoP
Authors: López Santiago Luis Miguel , Rohmer Serge , Díaz Pichardo René , Reyes Tatiana
Published: July 2019

The bottom of the pyramid (BoP) consists of 1.4 billion people living less than 1.25 USD per day. Fulfilling unmet needs of BoP people involves the design of products as a main activity. Designing products for the BoP faces two main problems. First, there is a general lack of understanding of the needs of users and second, traditional design methods may be limited in addressing the BoP context. Frugal innovation is positioned as a very interesting approach with the potential to adequately respond to the design challenges of the products for the BoP. However, studies in engineering design based on frugal innovation are still limited. In response to these issues, through an analysis and review of the literature, an exploratory mapping of the proposals in frugal innovation and the characteristics of the BoP was conducted. On the basis of the results, this paper defines a set of eight frugal criteria design and an identification of three dimensions that characterize a BoP context and two roles of BoP people. Finally, an association of BoP dimensions and roles with the key criteria of frugal design is proposed.
Digital Sketch Modelling: Proposing a Hybrid Visualisation Tool Combining Affordances of Sketching and CAD
Authors: Ranscombe Charlie , Zhang Wenwen , Rodda Jacob , Mathias David
Published: July 2019

Visualisation of ideas and emergent designs is an essential ingredient in design practice. Sketching and CAD represent two widely used visualisation tools, each with complementary affordances that dictate their typical use during the design process. Sketching has affordances of fast and fluent visualisation whereas CAD affords easy modification of detailed designs. This paper proposes a hybrid tool, Digital Sketch Modelling, investigating the extent to which it can deliver complementary affordances of both sketching to CAD. Analysis of diary entries made by 62 postgraduate designers using sketching, digital sketch modelling and CAD within a design project forms the basis of the study. Results illustrate how digital sketching over crude 3d digital models, combined with benefits of digital image editing software enhance affordance for easy visualisation of ideas. Concurrently, the level of software used in Digital Sketch modelling led to fewer concerns over the level of difficulty to modify designs, enhancing the affordance for easy modification. As such we conclude Digital Sketch Modelling does combine affordances indicating its potential benefit in use between sketching and CAD.

Published: July 2019

The scarce availability of water in highly populated cities is about to become a social problem. While the water service companies work on improving the distribution network in order to reduce losses, it is evident that one of the main problems is due to an excess of use of this resource by users. This consumption is relatively controlled when excessive consumption is clearly associated, in the consumer mind, with high costs. However, when users are in public places they tend to consume water because of a loss of correlation with costs. In this paper, we describe the design of a device to be installed in public environments, which aims to reduce the consumption of water. The device measures in real time the flow of water and sends the user visual and sound information trying to create a link between consumption and costs. The device has been installed in a university campus bathroom and has been tested. Test results show a reduction in water consumption, especially in the interactive prototype approach compared to the conventional treatment. Further modifications for future development of the interactive device is also discussed.
Towards a Theory for Unintended Consequences in Engineering Design
Authors: Walsh Hannah , Dong Andy , Tumer Irem
Published: July 2019

Conventional failure analysis ignores a growing challenge in the responsible implementation of novel technologies into engineered systems - unintended consequences, which impact the engineered system itself and other systems including social and environmental systems. In this paper, a theory for unintended consequences is developed. The paper proposes a new definition of unintended consequences as behaviors that are not intentionally designed-into an engineered system yet occur even when a system is operating nominally, that is, not in a failure state as conventionally understood. It is argued that the primary cause for this difference is the bounded rationality of human designers. The formation of unintended consequences is modeled with system dynamics, using a specific real-world example, and bifurcation analysis. The paper develops propositions to guide research in the development of new design methods that could mitigate or control the occurrence and impact of unintended consequences. The end goal of the research is to create a new class of failure analysis tools to manage unintended consequences responsibly to facilitate engineering design for a more sustainable future.
Method for Analysing Requirement Change Propagation based on a Modified Pagerank Algorithm
Authors: Gräßler Iris , Thiele Henrik , Oleff Christian , Scholle Philipp , Schulze Veronika
Published: July 2019

Complexity of products and systems is increasing through digitalization, interdisciplinarity as well as high technology maturity and new business models. In consequence, new product development (NPD) projects need to manage and satisfy a large number of requirements from a broad range of stakeholders. Yet, NPD projects are often delayed due to requirement changes. In this paper, a new method for analyzing requirement change propagation is presented. The method is based on the assessment of requirement interrelations structured in a requirements structure matrix by a modified page-rank algorithm. By the method, a high number of strongly interrelated requirements can be analyzed in an efficient manner. Additionally, higher-level interrelations as well as the relative weights of requirements are also incorporated in the analysis. Hereby, an efficient holistic approach towards the analysis of requirement change propagation is proposed.
Multi-level Decomposed Systems Design: Converting a Requirement Specification into an Optimization Problem
Authors: Beernaert T. F. , Etman L. F. P.
Published: July 2019

Complex technological artefacts are often decomposed into smaller components to keep their design manageable. The resulting challenge is to coordinate decisions that involve multiple components and to design components such that high-level targets are met. Analytical Target Cascading (ATC) is an analytical coordination method for the optimization of decomposed systems, which we aim to incorporate in systems engineering design process. To this extent, we relate the domain of engineering optimization to the domain of requirements engineering, and propose a method that constructs an ATC problem from functional specifications and requirements written in the newly developed Elephant Specification Language. The proposed method is demonstrated in the two-level design of an automotive powertrain. This contribution is a step towards design automation and is expected to increase the usability of decomposed optimization techniques.
Streamlined Assessment to Assist in the Design of Internet-of-Things (IOT) Enabled Products: A Case Study of the Smart Fridge
Authors: Dekoninck Elies , Barbaccia Francesca
Published: July 2019

This paper shows how designers of IoT-enabled products can assess the environmental impacts associated with the user behaviour and the service system around the product. High-quality secondary data and a user-behaviour survey were able to highlight critical aspects of a smart fridge's design. A streamlined LCA looked at just the in-use phase of the product within 4 PSS scenarios. The system included: the effects on the food waste; grocery shopping methods; fridge door openings; and how the users interact with the smart fridge features. The results show that a smart fridge as within a PSS can reduce the impact on the environment (GWP of 21,700 kg CO2-eq within the ‘average PSS scenario’ and GWP of 23,100 kg CO2-eq for the normal fridge with ‘typical scenario’). The product's increased emissions are counteracted by the reduction in GWP due to: reduction in food waste; and shifts from brick-and-mortar grocery shopping to e-commerce. Therefore some of the critical aspects of the product's design that are most influential on the environmental impact of an IoT fridge are: the design of the web-browsing capability; and the use-by date tracking system.
Reframing the Design Process: Integrating Goals, Methods and Manifestation into the Co-Evolution Model
Authors: Storm Rosa , van Maanen Jeffrey , Gonçalves Milene
Published: July 2019

In their early years of education, design students may experience difficulties in reframing design problems. Since reframing is linked to creativity, this may be problematic. While there are some models available to describe the reframing process, it is yet unclear how they are supporting design students. This study concerned the development and test of a framing model based on co-evolution transitions, through a two-part study: interviews with expert designers and workshops followed by group interviews with novices. The resulting model offers a way of thinking and a way of working, based on the fluidity of the design process. This study yielded two major insights. Firstly, students tend to perceive the problem space to be fixed once they defined it, even if they discovered disparate information along the way. Secondly, the developed model provides students with guidance and confidence in dealing with complex problems. Our results have a considerable impact on design education, as it is important to reinforce to design students that both the problem and solution understanding are fluid, and this model provides initial steps to help designers structuring their process.
Evaluating Innovative Projects for and with Elderly People: Insights from Participatory Design Contests
Authors: Jean Camille , Cluzel François , Vallet Flore , Yannou Bernard
Published: July 2019

Societies are challenged worldwide to maintain or improve the life of an ageing population. In the meantime, it is an opportunity for businesses to develop products and services for the elderly. Participatory design - or co-design - promotes not only to design for, but also with and by older adults. Current studies tend to emphasize more field investigations and co-ideation than evaluation of co- designed outcomes with seniors. We are interested in two 24 hours-innovation contests in 2017 and 2018, yearly involving 10 teams of 3 students, elderly persons as potential beneficiaries and innovation experts. The aim of this paper is to analyse the variability of evaluation of generated projects between the elderly people and the innovation experts. The comparative analysis relies on the grades and ranking of projects against five criteria. Results show that elderly people provide consistent evaluations, but with a positioning slightly shifted compared to the experts. We conclude on recommendations for the evaluation process with a jury including seniors.
How to Design for Joy / Satisfaction - Two Different Approaches on How to Tackle the Task
Authors: Atzberger Alexander , Boffa Eleonora , Montero Joaquin , Paetzold Kristin , Vajna Sandor
Published: July 2019

In the course of the IPD International Summer School, two teams addressed the topic of devel-oping an integrated product, with the constraint of it being joyful for the user. One team has chosen an agile development approach whereas the second team approached it in a plan-driven manner. With the starting conditions for both teams being equal, a direct comparison between the agile and plan-driven development approach can be undertaken. The different courses of action are displayed and the different ways on how to approach the topic of achieving joy for the user are outlined. The results as well as the challenges associated with each approach are dis-cussed and an outlook on the transferability to other fields is given.
A Computational Study of the Effect of Experience on Problem/Solution Space Exploration in Teams
Authors: Perisic Marija Majda , Martinec Tomislav , Storga Mario , Gero John S
Published: July 2019

This paper presents the results of computational experiments aimed at studying the effect of experience on design teams’ exploration of problem-solution space. An agent-based model of a design team was developed and its capability to match theoretically-based predictions is tested. Hypotheses that (1) experienced teams need less time to find a solution and that (2) in comparison to the inexperienced teams, experienced teams spend more time exploring the solution-space than the problem-space, were tested. The results provided support for both of the hypotheses, demonstrating the impact of learning and experience on the exploration patterns in problem and solution space, and verifying the system's capability to produce the reliable results.
Measuring Systems Engineering and Design Thinking Attitudes
Authors: Greene Melissa T. , Gonzalez Richard , Papalambros Panos Y.
Published: July 2019

Systems engineering and design thinking have been widely seen as distinctly different processes, systems engineering being more data-driven and analytical, and design thinking being more human- centred and creative. We use the term ‘design thinking’ to encompass the plurality of human-centered design processes that seek to unpack the core values behind design decisions. With the increased awareness that both systems engineering and design thinking need each other, the effects of a possibly persisting distinction on engineers’ attitudes toward these two processes are not well understood. In this paper, we describe the development and validation of a scale for measuring individual attitudes about systems engineering and design thinking. Thematic analysis of engineering and design literature is used to derive a Likert scale reflecting these attitudes. We use exploratory and confirmatory factor analysis to test and confirm this two-factor thematic representation, resulting in a 9-item Systems Engineering and Design Thinking Scale measure of attitudes.
Participatory and Inclusive Assistive Technology Innovation Clinics in Design Schools
Authors: Bhatnagar Tigmanshu , Patel Rohit , Roopchandani Bhavik , Ashraf Faisal
Published: July 2019

People living with disabilities can have needs for Assistive Technology (AT) that are out of the scope of occupational therapists, commercial markets and charitable distributions. For such needs, designers, engineers, makers and clinicians in the local community can design and fabricate AT through an inclusive, participatory, user centred design process. By tapping into the skills, creativity, facilities and knowledge of local design, medical, engineering and management schools, we can make clinics for AT innovation, practical design education, business incubation and product provision. Through two case studies, we demonstrate the necessary steps towards this novel approach to compassionately design, fabricate and deliver bespoke and scalable AT innovations. The practice is multidisciplinary, it empowers people with disabilities to creatively challenge their problems, contributes to design education and requires a system to ensure product quality and follow ups. We envision that over years, this practice can become a movement that is able to systematically knit the patched ecosystem for AT, while contributing to the global understanding of design for people with disabilities.
Revealing Insights of Users’ Perceptions: An Approach to Evaluate Wearable Products Based on Emotions
Authors: Liao Ting , Tanner Kesler , MacDonald Erin
Published: July 2019

The wearable products market is growing rapidly. Engaging users on an emotional level may be the key to long-term use and attracting new customers. While researchers have proposed various design approaches to realize design qualities for wearable devices, emotional needs are overlooked in the design process. To bridge this gap, we developed an approach with an online tool that uses a two-axis interactive collage for users to compare and evaluate wearable products with targeted emotion-related descriptive words. This approach enabled us to explore how users perceive products and identify types of emotions that were associated with their preferences for and perceptions of the product's form and visible characteristics. The study demonstrated this design approach to reveal insights into the relationships between product characteristics and design goals, such as user comfort, user delight, and perceived product usefulness. The results showed that products that resemble clothes were perceived as more delightful and comfortable. This study suggests that the approach can be further used to explore other design concepts or goals.
The Personification of Big Data
Authors: Stevenson Phillip Douglas , Mattson Christopher Andrew
Published: July 2019

Organizations all over the world, both national and international, gather demographic data so that the progress of nations and peoples can be tracked. This data is often made available to the public in the form of aggregated national level data or individual responses (microdata). Product designers likewise conduct surveys to better understand their customer and create personas. Personas are archetypes of the individuals who will use, maintain, sell or otherwise be affected by the products created by designers. Personas help designers better understand the person the product is designed for. Unfortunately, the process of collecting customer information and creating personas is often a slow and expensive process. In this paper, we introduce a new method of creating personas, leveraging publicly available databanks of both aggregated national level and information on individuals in the population. A computational persona generator is introduced that creates a population of personas that mirrors a real population in terms of size and statistics. Realistic individual personas are filtered from this population for use in product development.
Towards Virtual Assessment of Human Factors: A Concept for Data Driven Prediction and Analysis of Physical User-product Interactions
Authors: Wolf Alexander , Binder Nicole , Miehling Jörg , Wartzack Sandro
Published: July 2019

The early consideration of human factors in product development hugely favours the development of products, which excel with a positive user experience. The virtual environment of product development however, still has significant gaps in the virtual assessment and simulation of human factors, especially for user-product interactions composed of human movements. This motivates us to introduce a concept for data-driven prediction and analysis of user-product interactions. Heart of the concept is a predictive component that models the interaction between the user, represented by a musculoskeletal model, and the product, represented by product characteristics. We describe the implementation of this concept based on a pilot study for a lifting task. Motion capturing was performed to build a database and compare the results of our novel approach. The resulting kinematic and dynamic quantities show similar curve profiles with a small constant offset to the measured data. This indicates that the concept enables the virtual comparison of different designs or concepts regarding human factors.
Visualising User Experiences: Analysing Embodiment of UX in Autonomous Vehicle Concepts
Authors: Ranscombe Charlie , Rodda Jacob , Johnson Mark
Published: July 2019

The prospect of autonomous vehicles and associated technologies has disrupted traditional modes of vehicle operation and ownership. This requires automotive designers to shift their focus from designing vehicle form to consider the design of transport experiences. As such, there is a need to explore how best to support automotive designers in communicating user experiences (UX) alongside the physical design of vehicles. This paper presents an industry case study conducted with Ford Design Asia Pacific to assess the embodiment of UX in early concepts. Attributes of generalised model for UX are mapped to designers' storyboard illustration for the experience of an advanced concept for an autonomous vehicle interior. Results show how a mix of captions, sketches of users and contextual features illustrate different attributes of user experience. From findings we conclude firstly, the need to develop a toolkit to help designers communicate descriptions of as yet designed interactions. We also conclude that sketching contextual features of experience can provide a starting point to develop aspects of UX that can be used to differentiate and identify the Ford brand.
Assessing the Authenticity of the Student Learning Experience
Authors: Bissett-Johnson Katherine Mary , Radcliffe David F
Published: July 2019

Authentic learning is an approach to teaching where the learning is embedded in a real world context, in real situations or simulations, and offers students opportunities for problem solving challenges much like they will encounter in real life. This paper discusses and reflects upon the development a course designed to teach Socially Responsible Design approaches, methods and tools to Product Design Engineering students using global projects. Our research question was to investigate if this Socially Responsible Design course, it's structure, delivery, learning activities and assessments combined to deliver an authentic learning experience. Through informal interviews with staff, review of student reflections, review of university student feedback comments and consideration of final outcomes, all within the framework of Herrington and Oliver's nine elements of authentic learning, we found that this course did provide an authentic learning experience for many reasons. This study offers academics a frame work for reviewing existing and future courses with a view to creating or enhancing authentic learning experiences using project based learning
Biomimicry Design Education Essentials
Authors: Stevens Laura , De Vries Marc M.J. , Bos Mark M.J.W. , Kopnina Helen
Published: July 2019

The emerging field of biomimicry and learning to design with and for nature has expanded in recent years through a diversity of educational programs. Inspiration following natural forms may give the appearance of being sustainable, but the question remains, how sustainable is it? Misunderstanding the function of these forms may leave designers with products not as sustainable as desired. Biomimicry education addresses these issues by integrating three essential elements into their design thinking phases and by using analogical transfer while doing so. This field learns from nature as model, nature as measure, and nature as mentor, throughout the design process. Through examination, analyses and verification of students designs and reflective processes at The Hague University of Applied Sciences, this research considers natures analogies in educational factors, determining which elements are influential when incorporating biomimicry into design education.
Impact of Inventive Design Education through the Correlation between Students’ Grades and Individual Talent
Authors: Becattini Niccolo , Cascini Gaetano
Published: July 2019

This paper aims at assessing the impact of inventive design education on students attending a class on Methods and Tools for Systematic Innovation. The study stems from the difficulty to understand how much personal inventive talent influences the final evaluation, especially in a context where students are asked to solve open problems, as conceptual design ones. To overcome the potential bias due to the individual talent, the authors propose to determine the impact of their teaching activity by means of an ex-ante/ex-post correlation analysis. Several cohorts of students along the years have been asked to solve some design problems at the beginning of the course, when no topics have been thought yet. An adapted creativity metrics enriched to map course contents measures the students' performance at the beginning ot the class (ex-ante). These results get correlated to the students' final grades (ex-post) in order to highlight areas where teaching has a stronger impact and those where talent remains predominant.
Renewal of Design Teaching Resources by the Practice of Environmental Scanning
Authors: Roumy Akue Magali
Published: July 2019

Teachers' resources renewal is a critical aspect of design education. Design teachers update and renew their resources to keep their lectures and project topics up to date, in line with contemporary issues and societal changes, and to assure their lifelong learning and professional development. Yet, few studies were published on resource renewal process in design education. Researches usually focus on teaching resources and cultural capital qualification. This paper analyses the resource renewal process in design education. Our methodology comprehends the construction of a conceptual framework based on Environmental Scanning, which was studied through a qualitative study involving fifteen design teachers in France. Our results show that design teachers update and renew teaching resources according to their personal areas of interest and students' needs. Their renewal process is different depending on whether they are creating lectures and topics, they are working with other teachers or with external partners. Relationships and networks appear important, teachers rely on their network of colleagues, design practitioners and project partners to access emerging issues.
Student Reflections on Needs Finding in Community-Based Design Work
Authors: Loweth Robert P. , Daly Shanna R. , Sienko Kathleen H. , Liu Jiangqiong
Published: July 2019

Reflection is an important component in design skill development that helps designers better understand their design problem, develop better solutions, and improve their design approaches. This study explored the information that a student design team reflected on as part of a needs finding experience and the outcomes from these reflections. During the needs finding experience, the team exhibited reflection-in- action behavior as they used available data to form and iterate on explanatory hypotheses about potential community needs. After the needs finding experience, the team exhibited reflection-on-action behavior as they drew connections between their interview approaches and stakeholder responses and discussed changes they might make in the future. The team also identified situations where contextual factors of the stakeholder impacted their interviews, but during these reflections did not indicate how they might adapt their approaches to account for such factors in the future. These findings show that student designers can use reflection as a tool to improve their needs finding process but would benefit from pedagogical structures that might help them reflect more effectively.
Students’ Comprehension of Design Collaborations with External Organizations
Authors: Gottlieb Laura , Eriksson Yvonne
Published: July 2019

This pilot study examines how design students comprehend collaborations with external organizations— the roles and involvement of different actors in a design process. The study looks at two undergraduate courses where a total of 33 design students collaborate with a municipality and governmental agency. Data focuses on the students' terminology in regard to the external organizations and is collected through questionnaires, voice recording, workshops and written assignments. The data analysis is both quantitative and qualitative, focusing on the word frequency and semantics of the terminology. The results show that the students were not used to working closely to external organizations. This is reflected in the prevalent use of the term “client” instead of “collaborative partner”. Not working closely with organizations nor users is reflected in the students’ inabilities to handle the complexities that emerge when working with multiple stakeholder and users. At the end of the paper, suggestions are made of ways to develop students’ comprehension of ways to involve external organizations and users in the design process.
Drivers and Guidelines in Design for Qualification Using Additive Manufacturing in Space Applications
Authors: Dordlofva Christo , Borgue Olivia , Panarotto Massimo , Isaksson Ola
Published: July 2019

In recent years, reducing cost and lead time in product development and qualification has become decisive to stay competitive in the space industry. Introducing Additive Manufacturing (AM) could potentially be beneficial from this perspective, but high demands on product reliability and lack of knowledge about AM processes make implementation challenging. Traditional approaches to qualification are too expensive if AM is to be used for critical applications in the near future. One alternative approach is to consider qualification as a design factor in the early phases of product development, potentially reducing cost and lead time for development and qualification as products are designed to be qualified. The presented study has identified factors that drive qualification activities in the space industry and these “qualification drivers” serve as a baseline for a set of proposed strategies for developing “Design for Qualification” guidelines for AM components. The explicit aim of these guidelines is to develop products that can be qualified, as well as appropriate qualification logics. The presented results provide a knowledge-base for the future development of such guidelines.
Goal Oriented Provision of Design Principles for Additive Manufacturing to Support Conceptual Design
Authors: Schumacher Felix , Watschke Hagen , Kuschmitz Sebastian , Vietor Thomas
Published: July 2019

Additive Manufacturing (AM) offers a new degree in design freedom. However, in order to exploit AM's potentials in end-use products a methodical approach and suitable tools especially during conceptual design are needed. This paper presents a methodology for application in industrial practice, which should support the component conception for additively manufactured products. The approach focuses on a benefit-oriented preparation and provision of knowledge. In addition to general design methods for abstraction and promotion of creativity, AM-specific tools are introduced which support the provision of solution principles and process-specific restrictions. A broad applicability of the solution principles is ensured by an expansion of the solution space through abstraction. Consequently, product developers are sensitised to the new design possibilities of AM, on the one hand. On the other hand, they are supported in a holistic exploitation of design potentials in ideation in order to foster innovative solution ideas. Finally, the methodological procedure and the developed tools will be demonstrated in a workshop by using an example from industrial practice of the automotive sector.

Published: July 2019

The purpose of this work is to compare impact of regulatory focuses, namely preventive and promotional contexts, on creative ideation measured by novelty and usefulness. The study consisted of Singaporean students from an undergraduate university, and assessed their personality using the Big Five, Regulatory Focus, Creativity type and creativity outcomes measured with the Consensual Assessment Technique by completing a Collaborative Sketch exercise. Participants were randomly assigned to either the preventive, promotional or a baseline condition and tasked with a design problem necessitating a solution in the form of sketches. This study found the three conditions to yield significantly different novelty scores, but not usefulness scores. The most impactful condition on novelty was the baseline, indicating novice designers are capable of creating novel products and services. Those in the promotion condition created the second most novel sketches, or design solutions, followed lastly by the prevention condition. This may be so as novice designers consider larger space of solutions and may generate more ideas. This research is useful in creative pedagogy and for design professionals.
Design for Mass Adaptation of the Neurointerventional Training Model HANNES with Patient-Specific Aneurysm Models
Authors: Spallek Johanna , Kuhl Juliane , Wortmann Nadine , Buhk Jan-Hendrik , Frölich Andreas Maximilian , Nawka Marie Teresa , Kyselyova Anna , Fiehler Jens , Krause Dieter
Published: July 2019

A neurointerventional training model called HANNES (Hamburg ANatomical NEurointerventional Simulator) has been developed to replace animal models in catheter-based aneurysm treatment training. A methodical approach to design for mass adaptation is applied so that patient-specific aneurysm models can be designed recurrently based on real patient data to be integrated into the training system.

HANNES’ modular product structure designed for mass adaptation consists of predefined and individualized modules that can be combined for various training scenarios. Additively manufactured, individualized aneurysm models enable high reproducibility of real patient anatomies. Due to the implementation of a standardized individualization process, order-related adaptation can be realized for each new patient anatomy with modest effort. The paper proves how the application of design for mass adaptation leads to a well-designed modular product structure of the neurointerventional training model HANNES, which supports quality treatment and provides an animal-free and patient-specific training environment.

The science of ammunition lethality is a field that seeks to define the point at which military ordnance takes life and produces death. By historicising lethality's epistemology, I reveal the intellectual fissures and scientific uncertainties that have been reified and embedded into contemporary conceptions of military power. This not only tells us something about the processes by which science is subordinated to war, but also offers a new lens from which to consider the way knowledge claims about battle are co-constructed and legitimated through military practices. As a result, this article places science back into a narrative that otherwise frames the ontology of war in terms of fighting.
Architecture as event space: Violence, securitisation, and resistance
Authors: Shapiro Michael J.
Published: July 2019

Central to the conception of this article is the architectural theorist Bernard Tschumi's dictum, ‘There is no architecture without action, no architecture without events, no architecture without program … no architecture without violence.’ Shaped as well by Eyal Weizman's conception of ‘forensic architecture’, the focus of the investigation is on Israel's architecture of security and on the corresponding Palestinian architecture of resistance. Emphasising an encounter of cartographies that reveals the way Palestinians make life livable in response to the architectural violence they face, the analysis continues with reference to Yari Sharif's analysis of architectures of resistance and with a reading of a feature film, Hany Abu-Assad'sOmar(2013) in which the Separation Wall between Israel and Palestine is one of the film's primary agent/protagonists. The article surveys popular culture texts, focused on crime and espionage to analyse a range of security practices and breaches that amplify the analysis with attention to security issues in individual households, multiple-person dwelling arrangements, architectural locations throughout cities, and buildings housing governmental security agencies. That trajectory of architectural sites lends a micropolitical analysis to the macropolitical level of governmental policy and modes of resistance to it.
Wavelet-spectral analysis of droplet-laden isotropic turbulence
Authors: Freund Andreas , Ferrante Antonino
Published: July 2019

The spectrum of turbulence kinetic energy for homogeneous turbulence is generally computed using the Fourier transform of the velocity field from physical three-dimensional space to wavenumber $k$. This analysis works well for single-phase homogeneous turbulent flows. In the case of multiphase turbulent flows, instead, the velocity field is non-smooth at the interface between the carrier fluid and the dispersed phase; thus, the energy spectra computed via Fourier transform exhibit spurious oscillations at high wavenumbers. An alternative definition of the spectrum uses the wavelet transform, which can handle discontinuities locally without affecting the entire spectrum while additionally preserving spatial information about the field. In this work, we propose using the wavelet energy spectrum to study multiphase turbulent flows. Also, we propose a new decomposition of the wavelet energy spectrum into three contributions corresponding to the carrier phase, droplets and interaction between the two. Lastly, we apply the new wavelet-decomposition tools in analysing the direct numerical simulation data of droplet-laden decaying isotropic turbulence (in absence of gravity) of Dodd & Ferrante (J. Fluid Mech., vol. 806, 2016, pp. 356–412). Our results show that, in comparison to the spectrum of the single-phase case, the droplets (i) do not affect the carrier-phase energy spectrum at high wavenumbers ($k_{m}/k_{min}\geqslant 128$), (ii) increase the energy spectrum at high wavenumbers ($k_{m}/k_{min}\geqslant 256$) by increasing the interaction energy spectrum at these wavenumbers and (iii) decrease the energy at low wavenumbers ($k_{m}/k_{min}\leqslant 16$) by increasing the dissipation rate at these wavenumbers.

This paper presents a combined experimental and large-eddy simulation study to characterise the effect of aspect ratio on the near-wake structure of a square finite wall-mounted cylinder (FWMC). The cylinder aspect ratios (span $L$ to width $W$) investigated in the experiments were $1.4\leqslant L/W\leqslant 21.4$ and the oncoming boundary-layer thicknesses were $1.3W$ and $0.9W$ at a Reynolds number based on cylinder width of $1.4\times 10^{4}$ and $1.1\times 10^{4}$, respectively. In complementary simulations, the cylinder aspect ratios investigated were 1.4, 4.3, 10 and 18.6. The cylinder wake structure was visualised in three-dimensional space using a vortex core detection method and decomposed to its oscillation modes using the spectral proper orthogonal decomposition (SPOD) technique. A parametric diagram is proposed to predict whether the time-averaged wake structure is a dipole or a quadrupole pattern, based on oncoming boundary-layer height and aspect ratio. Cellular shedding occurs when the aspect ratio is high with up to three shedding cells occurring across the span for aspect ratios $L/W>18$. Each of these cells sheds at a distinct frequency, as evidenced by the spectral content of the surface pressure measured on the side face and the near-wake velocity. Amplitude modulation is also observed in the vortex shedding, which explains the amplitude modulation of the acoustic pressure emitted by square FWMCs. SPOD is shown to be a viable method to identify the occurrence of cellular shedding in the wake.
Adult Attachment and Mindfulness on Mental Health: A Systematic Research Synthesis
Authors: Jaurequi Matthew E.
Published: July 2019

Interest in the relationship between adult attachment and mindfulness has mushroomed over the past decade. Yet the associations between adult attachment and mindfulness related to mental health is less understood. This article provides a systematic research synthesis to elucidate the relationship between adult attachment, mindfulness, and mental health. Findings from 10 empirical articles identified that anxious and avoidant attachment and mindfulness together related to depression, anxiety, psychological functioning, and cortisol response. The effects of adult attachment and mindfulness on mental health is an exciting area for research and practice that can be advanced by the inclusion of key romantic relationship processes and partners within longitudinal or experimental study designs.
