INTRODUCING THE UBC CHAIR IN DESIGN ENGINEERING - BREAKING OUT OF DISCIPLINARY SILOS
Authors: Hodgson Antony J. , Kruchten Philippe B.
Published: April 2017

UBC was recently awarded an NSERC Chair in Design Engineering (CDEN). The focus of this chair is addressing the problem of ‘disciplinary silos’ in engineering education, primarily through enhancing cross-departmental and cross-faculty initiatives. Our principal initiative is a multidisciplinary senior design course which will bring together engineers from different departments in a year-long project sponsored by external clients. We will also establish a new building – the $6.6M Wayne and William White Engineering Design Centre – which will serve as the focal point for faculty-wide design activities.
IMPROVING PROBLEM SOLVING AND SOLUTION DESIGN SKILLS USING PROBLEM FLOW COACHES IN CAPSTONE PROJECTS
Authors: Rousseau Paul R. , Khomenko Nikolai
Published: April 2017

Engineers are known for their ability to solve problems and design solutions to those problems. There is an increasing concern that engineering education is failing to prepare students to properly address complex, ill-structured problems in the context of multi-disciplinary teams in order to produce innovative solutions and designs. Instructional solutions such as coaching, active learning, helping students develop metacognitive skills, and the direct teaching of creative problem solving skills have been proposed and will be discussed. This paper introduces a concept of “problem flow coaches,” who work closely with the capstone project teams. The problem flow coach, with expertise in systematic inventive problem solving methodologies, specifically OTSM (Russian language acronym for General Theory of Powerful Thinking) that is inclusive widely used problem solving methodology TRIZ, assists students in developing the cognitive and metacognitive skills needed to define, analyse and solve complex problems and develop innovative design concepts.
THE USE OF LEGO ® SERIOUS PLAY IN THE ENGINEERING DESIGN CLASSROOM
Authors: Bulmer Linda
Published: April 2017

With the belief that teaching design, innovation and entrepreneurship studies requires methods and techniques that are themselves innovative and entrepreneurial in nature, LEGO® SERIOUS PLAY™ (LSP) has been used within the Technology Management and Entrepreneurship (TME) Program at the University of New Brunswick, Faculty of Engineering, as a complementary instructional technique since 2005. LSP is a creative and experiential process that can facilitate strategic planning, problem solving, team building, and innovation mining through the use of specialized LEGO® brick kits. Designed for the corporate environment, it made its formal debut in 2002. Since then, over 250 global organizations, in 27 countries have used this facilitated thinking technique. Example companies that offer enthusiastic testimonials for the methodology include Daimler/Chrysler, Verizon Wireless, Ikea, and Pfizer. LSP is now emerging in the educational environment. The current generation of students, before becoming gripped to electronics, was encouraged by parents to use their hands and imaginations to construct models using LEGO® bricks. They were at one time ‘Imagineers’. In addition, engineering students tend to work hard and play harder. Thus it became desirable to test how introducing the element of play [1][2] with purpose into the Entrepreneurship and Design classrooms could awaken students’ creative energies that spur innovation. “Constructivism” [3] has been increasingly emphasized as an effective approach to learning. Also, the related “Constructionist” theory suggests that by using our hands and 3D modeling to explore ideas we can surface more information, past experience, intuition and understanding than we can effectively express through speech alone. Based on the promising LSP initial TME pilot results in 2006, it was predicted that Engineering students as a whole could further benefit from the LSP experience and use this form of concrete thinking to solve design/innovation challenges and teaming issues. The LSP pilot action research was extended in collaboration with graduating Civil Engineering students in their Team Capstone Design Course winter 2008. Lego based (LSP) workshops subsequently conducted demonstrated a positive impact on the design teams with respect to their views on team responsibility and accountability, ability to collaborate and cooperate as well as their awareness of team risks and responsibilities over those teams with no LSP workshop experience.
EVALUATION METHODS FOR FINAL YEAR PRACTICE ORIENTED DESIGN COURSES
Authors: Blatz J. A. , Britton M. G.
Published: April 2017

The curriculum debate is alive and well amongst engineering faculties across the country. Even as the Canadian Engineering Accreditation Board continues to move towards fostering more design in the curriculum the question remains as to what impacts this is having on creating practice ready engineering graduates. The term practice ready is not to imply they are ready to be registered as professionals in their jurisdiction, but is intended to imply they have enough understanding of the realities of working in the private and public sector to appreciate the many conflicting objectives and limitations organizations face when making decisions that involve a large component of engineering involvement. This paper presents a discussion of using case histories in a final year Civil Engineering course to introduce elements of institutional policy, business management and engineering practice through demonstration with case histories where decisions involved all these elements. The case histories involved discussion of legal claims and dispute resolution on projects where engineering and business considerations were weighed in concert to achieve final solutions. The class was broken into working teams to discuss the case histories at various stages where information to that point was presented. The groups reported on their position and what decisions they would take at each stage so they could appreciate how their position changed as new information became available. This paper will focus on how the curriculum material was evaluated in the context of the examinations. Given the focus around case histories, the evaluation process was difficult given any questions about the case histories covered was simply a recalling knowledge already gained. At the same time the skills to be evaluated were highly subjective and difficult to articulate in answers to specific one-off questions. As such a case study was used in the examination process with considerable success. This paper discusses the development of an examination, conducting the examination and marking the examination of a case study based problem.
ASSESSING PEER EVALUATION: A COMPARATIVE STUDY OF PEER EVALUATION METHODS USED IN AN ENGINEERING DESIGN COURSE
Authors: Ostafichuk Peter M. , Jones Claire F.
Published: April 2017

Peer evaluation is one way to address group issues in undergraduate teams while at the same time providing feedback and assessment. Two common evaluation methods (point- and rubric-based peer evaluation) are examined and compared in terms of student perception within a University of British Columbia second year mechanical engineering design course. As part of normal course requirements, 118 students in 20 teams completed two full-time multi-week design projects with six regularly-spaced peer evaluations. Student feedback was gathered through two online surveys. Students expressed a slight preference for the rubric style evaluation, citing increased fairness and helpfulness in the feedback. Regardless of evaluation approach, student perceptions of peer evaluation were statistically unrelated to external factors including GPA, gender, and Myers-Briggs personality type. The findings suggest, at least in the student mind, that the use of peer evaluation as a design project assessment tool is fair and unbiased. Additional survey data show students see peer evaluation as a useful tool in undergraduate team design projects and that they feel more comfortable with the prospect of engaging in peer evaluation in the workplace in future as a result.
INTEGRATION OF ART AND DESIGN IN MECHANICAL ENGINEERING
Authors: Ackerman M. Y. , Stout C. , Gajewski C.
Published: April 2017

Is Design a process or an art form? Traditionally design has been taught in Engineering as a process that started with the definition of a need for a product or a process and culminated in a deliverable that took the form of a project record and usually a set of manufacturing drawings. There was always a good deal of emphasis on design for manufacturing as well as the minimization of product cost. As a result of this, and our inability to judge "creativity", designs had a tendency to be fully functional but not very esthetically pleasing. In other words the designs worked but, as often as not, were ugly. It seems that most engineers are very "left brained". As a result they are very comfortable with the notion of calculating anything required to make the design functional and cost effective but are not at all comfortable in making the design "work" from an industrial design perspective. Leading manufacturers of products are not satisfied with designs that are only functional. They recognize that for a product to be successful it must function but must also appeal to the customer. To enable this to happen requires more than the traditional hard calculation of optimal functional parameters; it requires a team approach that brings both the hard technical side and the more artistic industrial design side.

REVERSE ENGINEERING: TENSION RATCHET DISSECTION PROJECT
Authors: Vanderlaan Jeremiah , Richert Josh , Morrison James , Doyle Thomas
Published: April 2017

We are a group of engineering students, in our first year of undergraduate study. We have been selected from one thousand first year students and have competed and won the PACE competition. All engineers share a common general first year, but we have been accepted into Civil and Mechanical engineering. This project was assigned as the final project in the Design and Graphics course. The project we are tasked with, called the Cornerstone Design Project, is to first dissect a product, discover how it works, dimension each part and create a fully assembled model using CAD software (Solid Edge V20 in our case). As part of discovering how it works we must benchmark it so the device can be compared with competing products. The goal of the project is to develop a full understanding of part modeling and assembly in Solid Edge, learn proper measurement techniques, and learn the process of reverse engineering and product dissection. All of these tasks were stepping stones to help us fully understand how the device, and all its components, work.
REFLECTIONS ON ENGINEERING DESIGN EDUCATION
Authors: Buchal Ralph O.
Published: April 2017

Engineering design has received increasing attention in the undergraduate engineering curriculum, and much progress is being made. However, deficiencies are still observed in many skills required to be a successful design engineer, including: design methodology, project management skills, engineering analysis and validation in design, engineering graphics, practical skills, and reflection. Important factors affecting these outcomes include clear understanding of the design process, mentorship and direction from engineering advisors, increased opportunity for practical experience, and clear expectations.
SPATIAL THINKING AND COMMUNICATIONG: A COURSE FOR FIRST-YEAR UNIVERSITY STUDENTS
Authors: Erhan Halil , Ben Youssef Belgacem , Sjoerdsma Michael , Dill John , Berry Barbara , McCracken Janet
Published: April 2017

This paper describes a course on spatial thinking and communicating designed by an interdisciplinary team and offered to first-year university students. An important goal was to introduce spatial thinking while accommodating the needs of the students from diverse backgrounds, educational goals and career pathways. Students in a first-year interdisciplinary cohort of 340 represented Mechatronics Systems Engineering, Business, Interactive Arts, Communications, and Computing Science. A major feature of the course design was an integrated laboratory, which served to amplify lecture content via practicing exercises aimed at developing their abilities to think and work spatially in 2D and 3D using tools including pencil and paper, digital and physical Lego, and a computer-aided design system. We describe our course design and team-teaching processes, realities that constrained our choices, the tools we use to assist our decision making during course design and delivery, and the structure and function of the teaching team. We also present selected student artifacts to demonstrate how students learned to think spatially. We then identify lessons-learned and revision plans.
TEACHING DESIGN FOR SAFETY THROUGH REAL WORK INCIDENTS
Authors: Brousseau Jean , El Ouafi Abderrazak
Published: April 2017

Good design means at least safe design. There is no doubt that engineering students have to develop the ability to design for safety in order to satisfy the expectations of the profession and of employers. According to the Canadian Engineering Accreditation Board, an appropriate exposure to safety and health must be part of any engineering curriculum. Design for safety principles can be taught in project-based courses. Those courses provide real-world contexts for the development of design for safety skills. Design minima established in standards, regulations, and handbooks can easily be integrated throughout the curriculum in engineering science courses. In association with safety, engineering science courses may go beyond the application of standards and guidelines and prepare the student to become a better designer. The Case Study approach is a very interesting pedagogical tool for engineering education and can be introduced in the most engineering courses. When based on real work incidents and investigation reports, case studies become a perfect instrument to expose students to safety as professional engineers should apply it. To illustrate the idea, this paper presents an example of a case study based on an incident that occurred with a scissor lift. This particular case was introduced in a machine design course and helped students to link safety concepts with machine design contents.
MANAGING COMPLEXITY & PROMOTING USABILITY: A USER-LED DESIGN APPROACH
Authors: Farahbakhsh Khosrow , Kelly Benjamin
Published: April 2017

The inability of designers to meaningfully engage end-users in addressing their needs has resulted in a market saturated with unusable devices. To increase usability and reduce complexity, we propose a user-led design process where addressing user’s real need is the goal rather than developing new technologies or products. Such an approach places emphasis on the process of design rather than the final product.
A CASE FOR SYSTEMATIC AND METHODICAL DESIGN ENGINEERING
Authors: Eder W. Ernst
Published: April 2017

Engineering aims to provide technical processes (TP) and technical systems (TS) to solve a specific task. The human aspects of designing to establish these TP and TS include action modes, expertise, and competencies. These lead to a conclusion that systematic and methodical design engineering is essential.
ENGINEERING DESIGN: STRUCTURE, VALUE AND ASSESSMENT
Authors: Yellowly Ian
Published: April 2017

Engineering design is the central process in the transformation of new ideas and conventional technology or practice into high value products and systems. Unfortunately the process is not highly valued within the research oriented University environment. At the same time government innovation policy is rooted in models better suited to the review of projects as opposed to systems or products; the value structure being biased towards discovery, (and perhaps use). The author attempts to describe the structure of typical design activities and using this model proposes simple metrics to allow the assessment of design content within research and development proposals.
DESIGN OF IN-SITU RIVER KINETIC TURBINES TEST FACILITY IN COLD WATER
Authors: Bibeau Eric , Kassam Shamez , Woods John , Gole Ani , Mosallat Farid , Vauthier Philippe , Molinski Tom
Published: April 2017

A river kinetic turbine testing program was initiated in collaboration with Manitoba Hydro and UEK Corporation in the Winnipeg River. The goal of this program is to determine if this renewable energy technology can economically generate power in remote and grid connected areas using river currents. Compared with other forms of power generation technology, kinetic turbines may be implemented with less infrastructure. Of importance is to implement engineering design solutions as part of the testing program subject to a fixed research budget, with operational and maintenance cost still unknown. This paper presents the design of the research project to develop a one-year demonstration of a UEK 60 kW turbine to assess its ability to produce power and determine annual operational and maintenance costs in cold weather applications. A research platform concept was developed to allow adjusting the turbine location to obtain different flow and turbulence conditions and be able to pull the turbine out of the water to perform maintenance work, all at minimal cost. A low cost anchoring system was also put into service to secure the research platform. Instrumentation of the turbine was designed to obtain power, voltage, pressures, flow, turbulence, turbine loads and vibration. In addition, a remote sensing system was implemented to monitor the turbine performance and condition. Innovative approaches to design and operational logistics may make kinetic turbine technology an economically efficient solution.
ENGINEERING STUDENTS AND THE LIBRARY - FORGING THAT CRITICAL FIRST LINK
Authors: Perry Edwin M.
Published: April 2017

Engineering librarians occasionally experience difficulty getting an initial “in,” that all-important first connection with engineering students and faculty. In part, that may be because many do not have engineering degrees themselves. That said, a fundamental question arises- where and how can they make that initial contact? Equally important, how can the goals of the engineering faculty and the Library support one another? Engineering schools usually have a first year course intended to introduce broad aspects of the profession, and to show that Engineering does not exist in isolation. Rather, it interacts with and impacts upon society in a multitude of ways. The Canadian Engineering Accreditation Board mandates those same goals, and also requires that students learn to communicate adequately, both orally and in writing, and work effectively as part of a project team. The University of Regina Faculty of Engineering uses two first year classes to begin this process. It is at that point, in the first semester, that a connection between incoming students and the Library starts to be forged.
THE IMPACT OF A UBIQUITOUS MOBILE COMPUTING ENVIRONMENT ON DESIGN ENGINEERING EDUCATION
Authors: Nokleby Scott B. , Pop-Iliev Remon
Published: April 2017

Providing students with a ubiquitous mobile computing environment is a key component of UOIT’s teaching and learning strategy which offered a unique opportunity to build its programs from the ground-up with a laptop program at its centre. While ensuring that its use was considered in every aspect of curriculum development, five undergraduate engineering programs curricula have been developed at the University’s Faculty of Engineering and Applied Science (FEAS) with a laptop-supported mobile computing environment at its heart. The laptops are equipped with a suite of program specific software. The focus of this paper is on the pedagogical benefits that have been achieved in design engineering education at FEAS as a result of the students’ ubiquitous access to the latest CAD/CAM/CAE and productivity tools. The laptop program enables improved delivery of design engineering training along with the opportunity of implementing novel teaching strategies.

MATHEMATICAL PROGRAMMING FOR THE SCHEDULING OF ELECTIVE PATIENTS IN THE OPERATING ROOM DEPARTMENT
Authors: Tan Y. Y. , El Mekkawy T. Y. , Peng Q. , Oppenheimer L.
Published: April 2017

The Health Sciences Centre (HSC) in Winnipeg handles a large portion of the surgical patients in the province of Manitoba, along with Northwestern Ontario, and Nunavut. After an extensive analysis of the surgical patient flow at the facility, it became evident that the Operating Room (OR) scheduling system is one of the major sources of artificial variation in this flow, affecting both the pre and postoperative departments. A two-stage multi-objective mathematical model is proposed for the scheduling of elective cases. Using data obtained from all elective cases actually scheduled during a five week period at the HSC, five weekly OR schedules are generated using the first stage of the proposed mathematical model. The results of the models schedules are compared to current schedules employed at the HSC, to verify its effectiveness and assess the improvements that can be achieved.
PROMOTING COLLABORATIVE, SELF-DIRECTED, HANDS-ON LEARNING IN ENGINEERING DESIGN IN UNDERGRADUATE AND GRADUATE TEACHING
Authors: Farahbakhsh Khosrow
Published: April 2017

The face of engineering education is rapidly changing as more emphasis is placed on a self-directed, problem-based and design-driven approach. The School of Engineering at the University of Guelph has recognized the importance of engineering design education by introducing capstone design courses and encouraging incorporation of design in many senior-level courses. Two recent initiatives include inclusion of a student-led laboratory design project in the Mass Transfer Operations course (ENGG*3470) and a self-directed, problem-based approach to teaching a new graduate course in Pollution Prevention Engineering (ENGG*6790). Both courses placed a significant emphasis on “learning by doing” and importance of “self-directed learning”. Both courses also encouraged the development of various design skills such as problem definition, information collection, collaboration, innovation, communication, life-cycle costing, etc. This paper provides insights on these two courses and the approaches used to ensure a collaborative, hands-on and self-directed learning experience for students.
EXPERIENCES WITH INTER-YEAR CAPSTONE DESIGN TEAMS
Authors: Mann D. D. , Petkau D. S. , Dick K. J. , Ingram S.
Published: April 2017

Design teams in industry are composed of individuals with diverse backgrounds at various stages of their careers. A unique set of group dynamics will be created with one member, likely someone with sufficient experience, assuming the responsibility of being the team leader. Design teams formed in engineering classes within the university setting typically consist of individuals at the same stage of their academic training, thus students do not experience the same group dynamics as they will find in industry. In an attempt to give undergraduate engineering students this experience, inter-year design teams were formed from engineering students registered in courses representing different stages of completion of the engineering degree. Students registered in the final-year design course were expected to assume the roles of team leaders or coleaders. This paper will discuss a number of issues that were observed with inter-year capstone design teams. It has been concluded that the disadvantages of inter-year design teams outweigh the advantages.
THE MELDING OF FORM AND FUNCTION
Authors: Winkelman Paul
Published: April 2017

The engineering design process is traditionally modelled as proceeding from the functional domain to the physical domain. Function thus represents more abstract concepts and the form or structure resulting from the design process as the more concrete. A comparison of mechanical design with process planning, however, reveals that this model does not apply to all areas of engineering design. In mechanical design, engineers select those forms they believe will perform the desired function; in process planning, engineers select those functions (i.e., machining operations) they believe will create the desired form. This reversal of form and function raises important issues concerning how engineering design should be modelled as form and function may not be as distinct as the traditional model of engineering design might suggest. This paper is an initial exploration to better understand the nature and the implications of this "reversibility". Potential benefactors of this research are computerized design tools which use form and function to aid designers. By building upon a framework which supports both the mechanical design and the process planning perspectives, the design tool promises to better serve the needs of its users.
CENTRALIZING INFORMATION IN ENGINEERING DESIGN DOCUMENTS
Authors: Weiss Peter Eliot
Published: April 2017

Two major challenges in teaching a general design course to first year engineers are: the multiplicity of discipline-specific design methodologies and the distinctiveness of their associated documents; the fact that unique engineering documents are generally discussed in discipline specific Engineering Design texts rather than Technical Writing text books which deal in depth with the other aspects of communication of concern to engineering students. In order to address these challenges, it would be helpful to collate methodologies and documents from across engineering disciplines and to analyse them for commonalities while maintaining the sense of their individuality.
ECOLOGICAL INTERFACE DESIGN FOR COMPLEX SYSTEMS

Ecological Interface Design (EID) has emerged as a viable framework of methodologies, tools, and techniques for generation of computer interfaces for the control of complex systems. It provides a method of using engineering design knowledge to directly inform the design and layout of interface graphical forms and has been experimentally shown to improve operator performance.
THIRD YEAR INTEGRATED DESIGN PROJECT FOR THIRD YEAR CIVIL ENGINEERING STUDENTS
Authors: Ruwanpura Janaka
Published: April 2017

There is a lack of courses for design education in civil engineering curriculum except in fourth year at many Canadian Universities. An innovative approach introduced and implemented by the author to promote design education at the third year using a design competition at the University of Calgary was very successful. Student learned design concepts, applied them in the third year using a real project, integrated several civil engineering deliverables in one project without doing them in a separate course, and gained experience to get ready for their final year design course through this design competition. The eight courses included in the competition comprise all civil engineering aspects including structural, geotechnical, transportation, environmental, construction, material, and project management. The lessons learned by implementing the competition for 2 years, the author suggests a new idea to introduce a third year design project for civil engineering students. The paper discusses the purpose, structure, student participation, deliverables of the new idea.
A THEORETICAL FRAMEWORK FOR AN INTELLIGENT DESIGN CATALOGUE
Authors: Winkelman Paul , Yellowley Ian
Published: April 2017

This paper outlines continuing work on the intelligent design catalogue. The intelligent design catalogue seeks to create a virtual design environment that is linked to a catalogue of standard parts. The theoretical framework for this research draws on several engineering areas. Within manufacturing, process plans can be developed in a virtual environment independently of the machines on the shop floor just as products can be conceptually designed independently of the standard parts available. The standard parts themselves can be grouped borrowing from classification schemes of Group Technology. Object-Oriented Programming (OOP) provides an environment for the development of the software that runs the intelligent design catalogue. As the objects of OOP parallel standard components, OOP also serves as a design paradigm after which the catalogue can be modelled. . Design theory suggests frameworks for developing a (semi-) hierarchical structure for cataloguing parts and design case studies offer insight into differences between novice and expert designers.

Published: April 2017

This paper reviews the teaching of design in the Industrial Design and Mechanical Engineering programmes at Carleton University. We summarize our approaches to design education and contrast them with the innate skills of students. Notably each curriculum puts increased emphasis on the facets of design that do not match the innate skills of the entering students. We conclude by discussing various aspects of design education as taught in the two programmes and potential mutual benefits to future design education planning.
VIRTUAL REALITY BASED END-USER ASSESSMENT TOOL FOR REPORT PRODUCT AND SYSTEM TESTING

Published: April 2017

It is known that a through understanding of the end-user is the most valuable information to improve design, training, maintenance and assembly/disassembly processes of products and systems. The most widely used method to analyze human-system interaction, user experiments, which requires a product prototype, a test environment and a researcher to watch and collect data. This results in a procedure that is time consuming and limited by geographical constraints. This paper proposes a virtual reality based automated user assessment tool. An event based data collection and analysis approach is designed. Initial results support the usefulness of method as an automated tool to detect problems in an evaluated system

STORMWATER MANAGEMENT DESIGN: MODEL FOR A SENIOR UNDERGRADUATE COURSE
Authors: Bradford Andrea
Published: April 2017

Stormwater management design makes up half of a fourth year undergraduate course that also includes design of water distribution systems and wastewater and stormwater collection systems. Learning is supported by lectures with PowerPoint presentations that include many images. Early emphasis is placed on understanding the effects of urbanization, in terms of hydrology, geomorphology, water quality and stream ecology. This leads to the objectives of stormwater management and discussion of both traditional and emerging design criteria, as well as provincial guidelines and municipal standards. The students gain an appreciation of the need for a ‘treatment train’ approach – prevention followed by lot-level, conveyance, and if necessary, end-of-pipe measures – to achieve the multiple objectives of stormwater management. Students master screening-level design that addresses land use, physical feasibility, climate, watershed opportunities and constraints, community factors, and the capability for various stormwater management practices (SWMPs) to meet various water quantity and quality objectives. Details and design examples for a range of SWMPs such as infiltration trenches, biofiltration swales, and extended detention wet ponds are presented, and a field trip reinforces the in-class information. The students gain design experience by means of a term project in which four person teams design the water-related infrastructure of a new subdivision. A Terms of Reference is provided at the beginning of the term. The design teams are responsible for a proposal, which initiates early project management, an oral progress report, and a final design report and presentation. Design labs provide an opportunity to introduce students to the software (EPA SWMM 5.0) but are primarily devoted to working on the design project. The design project is evaluated in terms of product and process, and both group and individual marks are assigned. Designs are evaluated prior to the final presentations enabling the instructor to provide substantive feedback before the course concludes. For the most part, the quality of work done by the students over the last several years has been exceptional. During the course, common feedback from the students includes “lack of direction” and “heavy work load.” Following the course, students appreciate the understanding of the subject material and the design experience gained, which they find to be very relevant to employment opportunities.

EXPLORING THE DESIGN AND DEVELOPMENT OF AN "ON-THE-SHELL" TUMBLING MILL ACOUSTING MONITORING SYSTEM
Authors: Martins Suda , Zepeda Joachim , Picard Benoit , Radziszewski Peter
Published: April 2017

In the mineral processing industry, tumbling mills are used in the size reduction or comminution of ore to a target size distribution. As the tumbling mill environment is quite violent it is difficult to monitor mill charge motion. One way is to develop an “on-the-shell” acoustic system. This system will be used in the determination of the charge toe angle of an operating tumbling mill. The instrument, microphone system with the appropriate data acquisition system, collects the acoustic data. An analysis of the signal determines the location of the toe. The results of this development along with some trial data are presented.
DESIGN OF A MOBILE BIO-DIESEL PRODUCTION FACILITY
Authors: Drake B. J. , Jacques M. , Binkley D. , Barghi S. , Buchal R. O.
Published: April 2017

In 2004/2005, a team of mechanical engineering students undertook an interdisciplinary capstone design project to design a mobile bio-diesel production facility capable of converting 500 L/h of used vegetable oil or animal tallow into bio-diesel fuel. Bio-diesel fuel has negligible sulfur content and significantly reduces the emission of particulate matter, e.g. soot and carbon monoxide, compared to the combustion of conventional diesel fuel. Furthermore, bio-diesel fuel is biodegradable, nontoxic, and can be produced from renewable feedstock. The mobile facility is capable of taking used vegetable oil from different sources and processing the oil while in motion, eliminating costs associated with transportation, land use and construction. A special filter was designed to remove any major particulate matter as well as wax-like substances formed by heating of the cooking oil during its operational life. A rotary vacuum filter was designed to continuously of remove wax and solid particles accumulated on the filter cloth. The wax and solid wastes, which are organic compounds, are readily converted to useful light organic molecules through a subsequent gasification process. A transesterification process was applied using methanol as a solvent and sodium hydroxide as a catalyst. A mix of unrefined bio-diesel fuel and glycerol, which is produced by transestrification, is sent to a glycerol separating tower. The separator was designed to efficiently separate bio-diesel fuel from glycerol. The bio-diesel fuel is neutralized by weak acid solution and washed by water to remove impurities. High-speed mixers were designed to create maximum contact between phases for efficient separation. The mobile facility is subject to vibration, which was considered in every aspect of the design. The facility will be powered by bio-diesel fuel, and heat recovery and water recycling were considered to minimize energy requirements. The project culminated in a final design report containing detailed engineering analysis and a comprehensive set of working drawings.
DEVELOPING PARTNERSHIPS WITH THE FIRE SERVICE TO ENHANCE FIRE PROTECTION ENGINEERING EDUCATION OPPORTUNITIES
Authors: Torvi David
Published: April 2017

Fire protection engineering is increasing in importance in Canada and other countries, especially with recent changes to building and fire codes. Fire protection engineering design is highly interdisciplinary, which can present challenges when developing courses in this area. At the University of Saskatchewan, this challenge has been partially addressed through partnerships with the fire service, and other universities and research organizations. This paper discusses the importance of considering the fire service in the design process, and provides examples of partnerships with the fire service in the Mechanical Engineering undergraduate program and in graduate research projects.
SUSTAINABLE INNOVATIONS FOR ELECTRICITY GENERATION IN ONTARIO
Authors: Zhang Yimin , Habibi Shiva , MacLean Heather L.
Published: April 2017

The electricity generation sector is far from sustainable; in Ontario, 77% of electricity consumed is generated from non-renewable sources such as coal, natural gas and nuclear. As a result, this sector contributes significantly to many environmental challenges including global warming, smog formation, and acid deposition. It is critical to improve the sustainability of electricity generation through the incorporation of sustainable design concepts. Sustainable design takes into account the environmental performance of a product or process over its entire life cycle (including design and development, raw material acquisition, production, use, and end-of-life). Innovative design has resulted in new technologies for electricity generation. Generating electricity from biomass is one of the alternative technologies which could have the potential to improve the sustainability of the electricity generation sector. In this research we examine various scenarios for displacing coal-based generation. Coal gasification is a mature technology and to replace some or all of the feedstock with biomass, a re-design of some portions of the electricity generation technology are required. The technical changes in the process depend on several issues including the physical and chemical characteristics of biomass. We evaluate the environmental performance of electricity generation from agricultural residues through conducting a life cycle inventory for three biomass-to-electricity scenarios for the Province of Ontario; 1) a 5% co-firing of agricultural residues with coal in existing coal plants, 2) a 15% co-firing of agricultural residues with coal in existing coal plants, and 3) a hypothetical power plant which produces electricity from 100% agricultural residues using biomass gasification technology. For comparison purposes, we analyze a current coal only option using plant specific data. We quantify life cycle energy use, greenhouse gas and air pollutant emissions for electricity. Our results suggest that on a life cycle basis electricity generated from biomass can achieve a reduction in greenhouse gas emissions of 4% (for the 5% biomass co-firing) to 96% (for the 100% biomass gasification) compared to the coal-only option. Similarly, reductions in air pollutant emissions (sulfur oxides, nitrogen oxides, and particulate matter) range from 4% to 98%. Our study indicates that life cycle analysis is a useful tool for assisting decision makers in the selection of more sustainable design options for future electricity generation.

Tumbling mills describe a class of mechanical systems defined by a cylindrical chamber filled with balls and/or rock that rotates around its own longitudinal axis. This class of mechanical systems is used to grind to a desired quality different material in at least three industries: mining, cement and metal powders industries (ore, clinker and metal powder). These tumbling mills range in size from small 1 ft diameter lab mills to a 40 ft diameter semi-autogenous industrial mill and are composed of three main interactive and interdependent elements: the mill shell, liners/lifters and charge. These three elements work together to impact energy to the mill charge through the rotational motion of the mill shell. As with any mechanical system, the natural frequency of that system is essentially dictated by its mass and stiffness. In the case of a tumbling mill, a rotating system, the natural frequency of a given mill, as seen by a stationary observer, is also a function of the rotation speed. The aim of this paper The consequence for a rotating mill, and for that matter any rotating system, is that if the natural frequency of the mill should happen to match the operating rotating speed of the mill, resonance of the mill will occur. The objective of this paper is to explore the effect of mill diameter, length on mill natural frequencies as well as outline further work.
EXPERIENCE OF PARTNERING WITH INDUSTRY TO ENRICH ENGINEERING DESIGN EDUCATION
Authors: Herring Heather , Gu Peihua
Published: April 2017

Involving industry in engineering design education would enhance quality of education and student experience as most design expertise resides in industry that can be accessed through guest lectures and interactions with students; and real, meaningful engineering design projects are needed for our students. Good industrial projects with enthusiastic industrial participation in the design capstone course would provide very valuable opportunity for students to gain meaningful experience and would prepare students better to be design ready engineers upon graduation. However, there are a number of challenges in association with industry participation. This paper reports our experiences in dealing with industry-based design projects as well as associated challenges. It is our experience and belief that these challenges can be successfully addressed if both university and industry treat the partnership from a long term perspective and provide reasonable resources to the partnership.
A COURSE IN MECHATRONICS AND CALLING THE BLUFF ON ACTIVE LEARNING
Authors: Surgenor Brian , Firth Kevin , Wild Peter
Published: April 2017

When one talks about the elements needed for the next generation of engineering students, a list of the keywords typically includes the following: active learning, integrated learning, just in time instruction, theory versus practise, written and oral communication, multidisciplinary and interdisciplinary teams, lectures, tutorials, laboratories, workshops and design projects. An elective course in mechatronics engineering at Queen’s University is put forward as an example of how one course can encompass all of these elements, and equally important, be able to promote the excitement and enthusiasm among the students for the subject in a manner that should be present in all engineering courses.
ATTITUDE, SKILL, AND KNOWLEDGE: (ASK) A NEW MODEL FOR DESIGN EDUCATION
Authors: Bakarman Ahmed A.
Published: April 2017

Design education is a multi domain disciplines incorporate different aspects that as a whole aims to create a designer. Designer creation is not a simple task, and require, beside other aspects they have to obtain and acquire during their school years, students to have some aspects impeded in their personality,. Educator’s role is to identify these aspects and direct their curriculum toward them. ASK, as an educational model, aims to identify them by decomposing design education discipline into manageable elements that reflect the main ingredients. The proposed ingredients are: professional attitude, design skills, and professional design knowledge. The main contribution of ASK is the ability to view this domain form a new perspective that is able to reflect the expectations of the professional.

DESIGN IN CHEMICAL ENGINEERING: WHAT ARE THE PERSPECTIVES
Authors: Yargeau Viviane
Published: April 2017

Design in chemical engineering should aim at reaching a balance between theory and practice in engineering education in order to have students better prepared for their future endeavors. As students progress through the curriculum they learn more fundamental engineering science, more design components are introduced into courses and the complexity of the design problems increases. Elements of design are introduced in many courses and culminate in a capstone design course. Current practices in Chemical Engineering at McGill University are described here and general perspectives are discussed.
TEAM-BASED LEARNING IN THE DESIGN MODULES OF A NEW, INTEGRATED, 2ND YEAR CURRICULUM AT UBC
Authors: Hodgson Antony J. , Ostafichuk Peter , Sibley James
Published: April 2017

The Department of Mechanical Engineering at UBC restructured its entire second year curriculum last year (2004-2005) to address numerous deficiencies associated with the conventional instructional model of numerous separate courses with a heavy lecture component. The design portion of the curriculum underwent the most dramatic restructuring – it is now taught in two blocks of four and three weeks, respectively, and the students learn in a thoroughly team-oriented modality which permeates all aspects of the course. In this paper, we explain the rationale for the structure of the design course, describe in detail how the course works, and provide a preliminary assessment of the impact on students’ learning.
MODEL-BASED DESIGN FOR SYSTEM INTEGRATION
Authors: Mostermanm Pieter J. , Ghidella Jason , Friedman Jon
Published: April 2017

System partitioning is essential to the design of complex systems such as automobiles. Complexity can be because of compounded phenomena or because of intricate behavior. This paper focuses on the compounding effect of integrating the different subsystems that result from the partitioning. In particular, it concentrates on subsystems, or features, that have an embedded computation part to them. Three types of feature integration are classified: (i) shared resources, (ii) communicating features, and (iii) interacting control. The integration is addressed from a Model-Based Design perspective. It is discussed how this allows managing the complexity of integrating computations because it is operative at a higher level of abstraction than even high-level programming languages.
