Typical Design

Based on a model of a transformation system, a complete set of classes of properties for all products is developed. The design specification should give a clear statement of the requirements for the product. Various kinds of product can be recognized. Consequently three typical design processes are: design engineering, industrial design, and integrated product development. For a design process, the proposed set of classes of properties provides a good guideline or heuristic for setting up a design specification. This set of classes of properties supports a directed creativity. It indicates where expertise is needed to obtain an optimal designed product.

Role Of Information

Engineering aims to provide technical processes (TP) and technical systems (TS) to solve a specific task. Human aspects of designing to establish these TP and TS include action modes, expertise, competencies and the role of information. Aspects of the design process include a methodology that can be applied, and the contrast of synthesis with analysis.

Designing is anticipating and establishing a product to fulfill a need. Design engineering is a function of industry offering technical systems. It involves iterative and recursive processing, a design specification, searching for solutions, evaluating, decision-making, and communicating, supported by obtaining and preparing information, verifying, checking, reflecting, and representing. The steps can be performed intuitively and/or systematically, using various methods, feedback, iteration and recursion. Engineering curricula should expose students to design methodology and theory to develop the ability and skill for designing. This exposure should occur for the whole class, not just by separate attention to individual students.

AbstractThe paper reports on a study that aims to gain an understanding of how senior engineering design students engage and attain throughout the various stages of the design process during a major design project. Following a literature review it sets out to answer 3 main research questionsQ1. Do students engage more with certain stages of the design process during major project work?;Q2. Do students attain better during certain phases of the design process during major project ?Q3. Is there a difference in this attainment between year groups of the same degree programme ?The methodology adopted employs an analysis of marks and an online questionnaire to collect data. Patterns and trends in how senior BEng and MEng Product Design Engineering students engage and attain within the design process are presented, identified and discussed and in turn used to inform reflection on the research questions set.

Relations Between Safety and Security in Technical Systems The subject of this paper deals with the relationship between safety and security of the man - machine system. In the above system a man can act both as a decision - maker and operator. His desired psychophysical efficiency lies in the undertaking the correct decisions as well as in the skilful machine control and operating.

Abstract We developed a new database tool to manage information during the product definition process. This tool is a result of an ongoing research program to coordinate marketing and design engineering efforts in new product developments, and consider the related life cycle issues early in the design process. The database tool facilitates a methodology that integrates customer and design information, and allows reuse of this information during redesign problems. This paper presents the development, implementation, and an example use of the database tool.

Blade profiles are used in many technical systems, including in the use of wind and water energy, and in aviation and shipping. The shape of the airfoil contour has a crucial influence on the resulting forces at the cross-section around the airfoil. The optimisation tasks are characterised by an exceptionally large number and dynamics of the influencing parameters. These are generated by a combined flow-related and structural mechanical simulation. The current research presented here takes up these core elements of the shaping processes and makes them more flexible and transparent than conventional design methodologies. The aim is to improve the design process through a direct and flexible mesh-contour coupling in such a way that the resulting shape change can be directly correlated to the initiating characteristic flow variable. The integration of the FEMSeq method enables the optimal distribution and reduction of the material without causing a failure of the overall structure.

Novel Design

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 student can select appropriate parts for other applications. Creativity is usually characterized by a wide search for solutions, especially those that are innovative. The search can be helped by this systematic and methodical approach. 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 mechanism to open and close the bow thruster covers for the Caravan Stage Barge.

Design Experience

The design experience of 3rd year undergraduates in Mechanical Engineering at Ryerson University, and the assessment of student design work, was found to be disjointed and highly variable across the program. To attempt to address this, the authors are constructing courseware to help instructors of non-design engineering courses embed rich and consistent design projects into their courses. A “lightweight” Fast-Design process was developed. Course-specific design project examples of the process are being developed for five 3rd year courses using this design process. Current versions of all courseware are freely available. This paper details the nature of the courseware and how it was designed, developed,and deployed for the project. To date, one case has been deployed, two developed, and two more are under development. While results are so far only anecdotal, there is reason to believe that our approach can noticeably improve the design experience of students in non-design engineering courses.
