In order to expand the instruction ofengineering design in courses that are predominantlyengineering science, the Chair in Design Engineering ofthe University of Victoria has launched a program tointroduce design mini-projects. The development andmanagement of these projects is conducted by the courseinstructor in collaboration with a Design TeachingAssistant. The first design mini-project has beendeveloped for Theory of Mechanisms, a third-year corecoursein Mechanical Engineering. The course isprimarily theoretical and includes four laboratoryprojects that are based on deterministic problems. Inorder to establish an appropriate project, a list oflearning objectives that complements the theoreticalcontent of the course and exposes students to anengineering design problem has been identified. Theproject consists in designing and building an automatonfor young children – a mechanical toy operated by a handcrank. Overall the project was successful, studentsrapidly embraced it, the submitted prototypes generallymet or exceeded our expectations, and the learningobjectives were achieved.

Design Ideas

This paper focuses on comparing and contrasting methods for assessing the variety of a group of design ideas. Variety is an important attribute of design ideas, because it indicates the extent to which the solution space has been explored. There is a greater likelihood of successfully solving a design problem when a more diverse set of ideas is generated in the early stages of design. While there are three existing metrics for variety, it has not been established how well they correlate with each other, so it is unknown whether they provide similar assessments of variety. This uncertainty inspired our investigation of the three existing metrics and, eventually, the development of a new variety metric — all of which we compared statistically and qualitatively. In particular, 104 design ideas collected from 29 sophomore mechanical engineering students were analyzed using the existing and new variety metrics. We conducted correlation analyses to determine if the four metrics were related and to what degree. We also considered the qualitative differences among these metrics, along with where they might be used most effectively. We found varying levels of statistically significant correlations among the four metrics, indicating that they are dependent. Even so, each metric offers a unique perspective on variety and may be useful in different situations.

Students learning design engineering at times need a good example of procedure for novel design engineering. The systematic heuristic-strategic use of a theory to guide the design process – Engineering Design Science – and the methodical design process followed in this case study is only necessary in limited situations. The full procedure should be learned, such that the studentcan select appropriate parts for other applications.This case example is presented to show application of the recommended method, and the expected scope of the output, with emphasis on the stages of conceptualizing. The case follows a novel design problem of a gangway for ship-shore transfer for the Caravan Stage Barge.

Rules Of Thumb

If the teaching of engineering is indeed the practice of engineering, then it stands to reason that the development of engineering curricula can be treated as an engineering design problem. In this paper, the authors apply the engineering design process to develop a list of courses, for a Mechanical Engineering Program, that conforms to the constraints of the Canadian system of engineering accreditation. For the purpose of this exercise, the following steps are used to define the engineering design process: identical and delimit the problem, establish the outline of the solution (and alternatives), break the problem into its constituent parts, analyze the parts, synthesize the parts into a final configuration, and document the solution. The limits and constraints on the solution are based on the criteria specified by the Canadian Engineering Accreditation Board (CEAB), the syllabus specified by the Canadian Engineering Qualifications Board (CEQB), some common rules-of-thumb, and previously published work by the authors. By utilizing the engineering design process, schools of engineering and applied science can ensure that their curricula, at least at the level of the course specification, will conform to the CEAB and CEQB requirements. As a final exercise, variations on the curriculum are studied to analyze the possibility of introducing such additional elements as options and minors, expanded studies in the arts and humanities, and development of skills in additional languages.

Problem formulation is an essential design skill for which assessment methods have been less commonly developed. In order to evaluate the progress of a group of graduate students in mechanical engineering design in regard with the problem formulation skill, they were asked to work on three design problems using the Problem Formulator web tool during their course work. Changes in a set of measures elicited from this data were examined in addition to sketches, simulations, and working prototypes. Inventories of requirements and issues, as well as concepts derived from morphological charts were created to assess designers’ skills and outcomes.

The most difficult design problem will include various design parameters along with the tables. Finding out the design space and ultimate solutions to those problems are still biggest challenges for the area of complex systems. This chapter is all about suggesting the use of Genetic Algorithms to enhance maximum engineering design problems. The chapter recommended that Genetic Algorithms are highly useful to increase the High-Performance Areas for Engineering Design. This chapter is established to use Genetic Algorithms to large number of design areas and delivered a comprehensive conversation on the use, scope and its applications in mechanical engineering.

Abstract The study presented here explores the influence that an educational intervention has on students in generating requirements during a design task. An experiment was performed in a fourth-year level mechanical engineering design course in which student participants are given a design problem for which they generated a list of requirements, a lecture on requirements in engineering design, and a second design problem for which they generated a second list of requirements. The results from the two problems were tested for determine whether the problems were similar in terms of variety and novelty of requirements generated. The effects of the lecture were evaluated by comparing results from the pre- and post-lecture activity with the two problems. Variety was assessed by sorting the individual requirements generated by each participant into eighteen categories. Novelty was evaluated on the level of uniqueness of the requirement against the complete set generated by all participants, based on both syntax and semantic filtering. The findings suggest that the lecture had a positive impact on the students in increasing the variety of the requirements generated individually by the participants. Further, all the identified novel requirements belonged to the activity performed after lecture.

At RMC, in Mechanical Engineering, the third-year course MEE 303 ‘Principles of Engineering Design’ consists of 12 lectures and two mini-projects, one for redesign, and one for novel design. The redesign alternates between a water valve and an automotive oil pump. This case study is now up-to-date according to the most recent developments in the theoretical framework that is the basis for the systematic and methodical process. The search for solutions in this process involves creativity supported by systematic working.An automotive oil pump is to be redesigned for revised conditions. The existing oil pump originated from the 1970’s, and was used in a V-8 engine. A reconstituted set of engineering drawing was prepared. Using the recommended systematic procedure, and other appropriate methods, students were asked to perform the redesign process: to develop a design specification, to analyze the existing pump to detect organs and functions, to explore the solution field with a morphology, and to suggested an improved embodiment. The case study as presented here serves as a sample solution.

Abstract This paper presents a case study of Jeff, a mechanical engineering senior, and his experience with design in two different contexts — one in the classroom and one extracurricular. After a year-long study of undergraduate engineers, Jeff revealed marked differences in his uptake of design principles and reflexivity toward his thinking within the discipline. We explored with Jeff the critical differences and experiences that led to his changes once we had completed data collection with his peer cohort of undergraduates. We explored Jeff’s interpretation of the differences he considered as positive changes, the attributes of applying principles of problem typology, and the requisite context required to achieve these changes as a student. Through qualitative analysis four assertions are examined — improved approach to design problem solving, broadened view of design, engineering as multiple types of problems, and relevance to the profession — and validated through a member check. Potential implications for engineering education, especially as it pertains to design education are briefly described.
