Authors: Strasser Lauren E. , Orr Serena L. , McMillan Hugh J. , Doja Asif , Callen David J. A. 
Published: July 2019

ABSTRACT:Background:In 2013, a task force was developed to discuss the future of the Canadian pediatric neurology workforce. The consensus was that there was no indication to reduce the number of training positions, but that the issue required continued surveillance. The current study provides a 5-year update on Canadian pediatric neurology workforce data.Methods:Names, practice types, number of weekly outpatient clinics, and dates of certification of all physicians currently practicing pediatric neurology in Canada were obtained. International data were used to compute comparisons between countries. National data sets were used to provide information about the number of residency positions available and the number of Canadian graduates per year. Models for future projections were developed based on published projected population data and trends from the past decade.Results:The number of pediatric neurologists practicing in Canada has increased 165% since 1994. During this period, wait times have not significantly shortened. There are regional discrepancies in access to child neurologists. The Canadian pediatric neurology workforce available to see outpatient consultations is proportionally less than that of USA. After accounting for retirements and emigrations, the number of child neurologists being added to the workforce each year is 4.9. This will result in an expected 10-year increase in Canadian pediatric neurologists from 151 to 200.Conclusions:Despite an increase in the number of Canadian child neurologists over the last two decades, we do not predict that there will be problems with underemployment over the next decade.
Automated Exploration of Design Solution Space Applying the Generative Design Approach
Authors: Li Haibing , Lachmayer Roland 
Published: July 2019

AbstractDesign is a complex problem-solving activity that transforms design restrictions and requirements into a set of constraints and explores the feasible solutions to satisfy those constraints. However, design solutions generated by traditional modeling approaches are hardly to deal with such constraints, particularly for the exploration of the possible design solution space to enhance the quality of the design outputs and confront the evolving design requirements. In this regard, the Generative Design Approach (GDA) is considered as an efficient method to explore a large design solution space by transforming the design problem into a configuration problem. Fundamentally, GDA explores and stores all the necessary knowledge through a design skeleton and a set of design elements. Thus, design solution space is easily explored by configuring variable design elements via iterative design processes. Further, the output model is not only a design solution but also a design concept that designers could manipulate to explore unconsidered design configurations. Finally, a crank creation as a running example confirmed that GDA provides concrete aids to enhance the diversity of design solutions.
Integrated and Customer-Oriented Material and Process Selection by Sensory Multi-Criteria Decision-Making
Authors: Schneberger Jan-Henrik , Kaspar Jerome , Vielhaber Michael 
Published: July 2019

AbstractToday, product success more than ever depends on the satisfaction of consumer needs. Besides, manufacturers need to shorten development cycles and accelerate product release in order to stay competitive. This is achieved by applying customer-oriented methods allowing for fast and reliable acting. During the early phase of product development, requirements acquisition is crucial for later success of products, since specifications are most influenceable at this point. Referring to the decisive concept generation phase, material and production definition is difficult due to the highly complex interrelations between material properties, production process capabilities, and resulting product characteristics. Especially in the context of lightweight design, concurrent material and processing technology selection must be considered due to its various possible interfaces.Thus, this contribution outlines an integrated approach towards an enhanced material and process related, customer-oriented requirements acquisition during the early phase upstream of product detailing. Here, conventional multi-criteria decision-making and tactile recognition are employed in an agile transformation model.
Investigating the Influence of the Decoy Effect in Pairwise Comparison in Terms of Idea Selection in the Product Development Process
Authors: Tanaiutchawoot Narucha , Bursac Nikola , Rapp Simon , Albers Albert 
Published: July 2019

AbstractMany activities in the new product development requires the decision making to find the final solution from multiple alternatives and make an evaluation. Even methods to support decision maker are available, the decision can go to the wrong direction because of heuristics. “Decoy effect” is a heuristic that appears in a comparison when 2 of 3 alternatives are similar but different in quality. The alternative that is similar but better in quality is possibly selected. The paper aims to understand the decoy effect by investigating it in the pairwise comparison that is a powerful technique for comparing alternatives. In an experiment, 3 ideas for the next generation of apple peeler are compared in pairs with different sequences. An impact of the decoy alternative on the comparison between other two alternatives, is investigated. Results show low impact of the decoy effect in the pairwise comparison, but this effect induces a high chance of selecting the decoy alternative when comparing the results from this study and the previous study by proposing 3 alternatives in the same sequence. Applying pairwise comparison to avoid decoy effect is thus an idea that will be further investigated.
On Vehicle Evaluation and Design Using Data Envelopment Analysis with Hierarchical Concepts

Published: July 2019

AbstractIn recent years, product complexity in terms of function and structure has been driven by technological development in complementary components. Designing unbiased product evaluation metrics being to grasp the complex relationships of product features, and able to capitalize on market needs has become a challenge in industrial practice.In this paper, we propose a hybrid framework in which evaluation models are generated by integrating Interpretive Structural Modeling (ISM), Hierarchical Clustering and Data Envelopment Analysis (DEA). Whereas ISM constructs hierarchical digraphs (skeletons), Hierarchical Clustering reduces dimensionality of pairwise comparisons (correlations) of design variables, and suggests possible evaluation configurations, and DEA computes weights to provide optimal evaluation metrics. Our computational experiments using more than twenty thousand vehicles from 1982 to 2013 confirmed the feasibility and usefulness of DEA with hierarchical concepts to generate the optimal vehicle evaluation metric, and to suggest configurations for vehicle design layouts.
Perspectives on Innovation: The Role of Engineering Design
Authors: Isaksson Ola , Eckert Claudia , Borgue Olivia , Hallstedt Sophie I , Hein Andreas Makoto , Gericke Killian , Panarotto Massimo , Reich Yoram , Öhrwall Rönnbäck Anna B 
Published: July 2019

AbstractThe aim of the paper is to foster a discussion in the engineering design community about its understanding of the innovation phenomena and the unique contribution that comes from engineering design. The paper reports on the dialouge originating from a series of workshops with participants from different backgrounds in engineering design, systems engineering, industrial design psychology and business.Definitions of innovation are revisited as used in business, management and engineering design contexts. The role of innovation is then discussed related to product development from (i) the management perspective, (ii) a systems architecture perspective and (iii) in relation to sustainable development as one driver of innovation.It is argued that engineering design has a central role in how to realise the novelty aspect of innovation and often plays a critical role in maturing these into the valuable products, and there is a need to articulate the role of engineering design in innovation to better resonate with the business and management research.
Pugh Controlled Convergence and Social Choice Theory
Authors: Nicholson John Morgan , Collopy Paul 
Published: July 2019

AbstractThe Pugh Method of Controlled Convergence is evaluated based on social choice theory, both from an axiomatic basis, and by examining all possible cases of attribute ranks for a range of numbers of alternatives and numbers of attributes. The evaluation shows that, for a typical Pugh application, concept selection varies with the arbitrary choice of datum or is simply incorrect in about one-third of the cases. While there are merits to the iteration steps and creation of new alternatives within the Pugh method, a simpler and more expressive concept ranking procedure can give far superior results.
Reflection-in-Action When Designing Organizational Processes: Prototyping Workshops for Collective Reflection-in-Action
Authors: Wegener Frithjof Eberhard , Guerreiro Gonçalves Milene , Dankfort Zoë 
Published: July 2019

AbstractIn this paper on designing organizational processes, we combine insight on reflection-in-action with the role of reflection and experimenting from the organizational routine dynamics literature. Illustrated through a case at a strategy consultancy, we show how a prototyped workshop can elicit reflection-in- action when designing organizational processes. The artifacts used in the prototyped workshop made previous implicit assumptions about the work more explicit. This led to on the spot reflection-in-action of how to improve the prototype. This shows how collective reflection-action can be created by creating a space for reflection, that simultaneously allows for experimentation. Future research between design science and organizational science would thus be fruitful when studying the role of collective reflection- in-action when prototyping organizational processes.
The PSI Network Model for Studying Diverse Complex Design Scenarios
Authors: Reich Yoram , Subrahmanian Eswaran 
Published: July 2019

AbstractDesign pervades our world in variety and complexity that is difficult to grasp. Different disciplines and researchers take one or few perspectives to study, model, and try to understand design, why it fails and when it succeeds. However, without a comprehensive model, the value of such approaches is limited. We created a framework – the PSI (Problem, Social and Institutional Spaces) framework – that includes several models, ranging from simple to complex, networked, and hierarchical or recursive that can be used to model all design scenarios. In what follows, we demonstrate the network version of this framework, how it is used, and what insight it can present. The diversity of situations we present, mergers and acquisitions of companies, collaborations between industry and university, large multi- organizational projects, and a very complex project, as well as other cases we do not present here, confers the validity of utility and potential of the PSI framework.
The Role of Enabling Technologies in Transformative Innovation
Authors: Marion Tucker , Friar John 
Published: July 2019

AbstractThis study is an exploratory analysis of enabling technologies’ influence on the trajectory of industry development using a co-evolutionary model of technology development. When combined, enabling technologies can create new technology-market industry cycles, resulting in transformative innovation. The research approach of this empirical study is to use both primary and secondary data to create a history of the robotics industry and to explore the pre and post changes in the industry from the inclusion of enabling technologies over multiple generations. We propose a new model for understanding the theoretical and practical study of technology development through the lens of enabling technologies and their development and maturity cycles.
Usability Evaluation of Software Tools for Engineering Design
Authors: Hashemi Farzaneh Helena , Neuner Lorenz 
Published: July 2019

AbstractMuch of the work in design research focusses on the development of methods and tools to support engineering designers. Many of these tools are nowadays implemented in software. Due to the strongly growing use of computers and smart devices in the last two decades, the expectations of users increased dramatically. In particular users expect good usability, for example little effort for learning to apply the software. Therefore, the usability evaluation of design software tools is crucial. A software tool with bad usability will not be used in industrial practice. Recommendations for usability evaluation of software often stem from the field of Human Computer Interaction. The aim of this paper is to tailor these general approaches to the specific needs of engineering design. In addition, we propose a method to analyse the results of the evaluation and to derive suggestions for improving the design software tool. We apply the usability evaluation method on a use case - the KoMBi software tool for bio-inspired design. The case study provides additional insights with regards to problem, causes and improvement categories.
Design for Extremes: A Contour Method for Defining Requirements Based on Multivariate Extremes
Authors: Haselsteiner Andreas F. , Reisenhofer Rafael , Ohlendorf Jan-Hendrik , Thoben Klaus-Dieter 
Published: July 2019

AbstractThe design of various products is driven by requirements that describe extremes. In marine structural design, joint extremes of environmental variables like wave height and wind speed are used to define load cases. Similarly, in ergonomic design minimum and maximum values of anthropometric variables are considered to make sure a product is suitable for a wide range of users. Here, we present a method that supports designers to define requirements using joint extreme values: the requirements contour method. The method is based on structural engineering's environmental contour method and uses a dataset and statistical methods to specify a region in the variable space that must be considered in the design process. That region's enclosure is the requirements contour and holds the joint extremes. After formally describing the method, we give an illustrative example of its usage: we use it to define requirements for the design of an ergonomic handle for a power tool. The requirements contour method is a field-independent approach to design for extremes. In the tradition of design for X, we think that a design project can benefit from applying methods that focus on different 'X's.
Organisation Design Seen through Systematic Design

Published: July 2019

AbstractOrganizations seeking to improve their performance, like Corporate Social Responsibility targets, face a key organisational design challenge. Designing the key components of the organization and their layout will have major impact on performances, and needs thus a robust design process. Organisation theory provides several models and methods to answer that need. Yet this design process has not been confronted to design methods literature, such as systematic design. The aim of this paper is to provide a synthesis of multiple theoretical elements coming from organization sciences, confronted with a classical engineering design model, to reveal similarities, differences and lacks of current literature on organization design. Our analysis of the available literature on organisation theory, organisation design and change management showed that this design process is close to systematic design, but we also highlighted several breaks in the design process, such as the lack of functional approach.
Scaling of Technical Systems Using an Object-Based Modelling Approach

Published: July 2019

AbstractCompanies that operate and manufacture products in the technical area are exposed to increasingly challenging market situations. The developed products should be individualized to the customers' needs while offering high quality at an acceptable price.The temporal and especially economic claims are constantly growing, forcing the companies to develop a given product that matches the cost-side as well as the technical requirements in a short period of time. Following an initial development, it is often necessary to provide further product variants regarding a modified geometry or performance. A time and cost efficient way is the scaling of the initially developed product.Existing scaling methods focus on uniform geometry changes, not taking into account influences from non-uniform requirement or geometry alterations. Therefore, this article proposes an approach on how to modell and assess the outcome of a scaled assembly, based on the connection of individual scalable components inside an object-based approach.
Looking for Inspiration: Understanding the Information Evaluation and Seeking Behavior of Novice Designers During Creative Idea Generation
Authors: Damen Nicole , Toh Christine 
Published: July 2019

AbstractInformation usage is a key aspect of creative cognition and has been shown to influence design outcomes. The goal of this study was to investigate the information seeking behavior of student designers while validating a previously developed “Typology of Design Information” framework. Participants were asked to use and evaluate pieces of information during the idea generation process. Results show a discrepancy between the information that participants naturally sought out and their perceived utility (helpfulness) of the information. However, individually significant relationships between perceived utility and behavior were found with features generated by participants, suggesting that even though participants' perception of the utility of information pieces and their actual behavior are not related, both constructs have an identifiable influence on design outcomes. This study advances the Typology of Design Information framework by empirically exploring the link between the types of information used by novice designers and the ideas generated, and it illustrates that participants employ complex cognitive behavior when engaging with design information to generate novel ideas.
The Product Developer in the Centre of Product Development: A Systematic Literature Review on Describing Factors
Authors: Albers Albert , Heimicke Jonas , Spadinger Markus , Degner Nadine , Duehr Katharina 
Published: July 2019

AbstractIn the uncertain process of product development, the developer is decisively responsible for product success. He operates in a complex environment that directly influences his synthesis and analysis activities. The context of the socio-technical system of product development has already been extensively researched and defined by a large number of factors. However, the developer is described as part of the context and not as the centre, which means that many of these factors have no interaction with the developer. For the design of methods and tools that support the developer in his activities in the development process, a summarizing understanding of the influences on and by the developer is necessary. In order to create a unified understanding of the developer at the centre of product development, a Systematic Literature Review was conducted. In this article, the procedure and findings are presented. The aim was to identify factors from the literature that significantly influence the interaction of the developer in his environment. As a result, these were documented in a model, which represents the basis for further, human-centred research in the context of product development.
A New Method of Human Response Testing to Enhance the Design Process
Authors: Kalantari Saleh 
Published: July 2019

AbstractThis paper presents a new method of human-response testing to enhance the success of designs. Rather than waiting until after a building is constructed to see how the design will affect human users, we developed a high-resolution virtual-reality platform to present design variations to the study participants. This technique allowed us to make very precise adjustments in design variables (e.g., the ceiling height, or the placement of windows) within the same overall structure, thereby obtaining more empirically rigorous comparisons than is possible in traditional post-occupancy studies of completed buildings. In addition, this approach allowed us to collect a variety of biometric data, such as EEG signals, heart rate, head motions, and other indicators of attention and stress, while the study participants interacted with the virtual environments. The overall outcome of this research method will be to improve the human quality of the built environment and to promote data-driven innovation in the design field.
Investigating the Impact of Spatial Augmented Reality on Communication between Design Session Participants - A Pilot Study

Published: July 2019

AbstractSAR provides an unobtrusive implementation of AR and enables multiple stakeholders to observe and interact with an augmented physical model. This is synonymous with co-design activities and hence, there is a potential for SAR to have a significant impact in the way design teams may set-up and run their co-design activities in the future. Whilst there are a growing number of studies which apply SAR to design activities, few studies exist that examine a particular element of a design activity in a controlled manner. This paper will begin to fill this gap through the controlled study of SAR and its effects on the communication between participants of a co-design activity. To do so the paper compares a controlled design session, using more traditional methods of design representations (3D models on a screen), to sessions run using SAR. The sessions are then analysed to gather information on the gestures used by the participants as well as the overall efficiency of the participants at completing the set design task. The paper concludes that the data gathered tentatively supports a link between the use of SAR and improved communication between design session participants.
Knowledge Management for Problem Solving Using Semistructured Contradiction Matrix Based on Physical Quantity Description
Authors: Murakami Tamotsu 
Published: July 2019

AbstractA Contradiction Matrix of TRIZ that classifies problems to solve as contradictions of features is an effective framework of knowledge management for problem solving. The features, however, may have a problem of completeness because they may not cover contradictions about all physical phenomena. In addition, rigidly structured Contradiction Matrix may have a problem of searchability because a relevant contradiction may not be properly searched if a recorder and a retriever describe it differently. To solve these problems, this paper proposes a semistructured contradiction matrix using not TRIZ features but physical quantities in SI unit. To enable not only exact match but also partial match in searching for relevant contradictions, dimensional similarity and qualitative value similarity of physical quantity and similarity between contradictions are defined. The proposed method is implemented as software in Python and contradictions are described in XML and stored in a semistructured matrix. From the result of similarity calculation between stored contradictions, possible effectiveness of the proposed method is confirmed.
