Engineering Design Process

Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation". (Engineering Design, 2006)
problem, an existing condition in need of change, a challenge to look ahead for problematic conditions of the future, of design and construction. Because it is important for the engineers to be sure that they understand the problem thoroughly, the first step in the design process is for each group to state the problem. (Garmire, 2002)
To recognise the problem requires the ability to think laterally, to anticipate the unexpected and to appreciate the aesthetics of problem solving as well as the material aspect. The aspects within which the problem is being addressed must be understood. (Eng, 2006)
Because statements of problems exist within a context, they usually involve bias and often imply solutions. Effective engineers learn to observe the context and eliminate bias. They must clarify the problem statement by looking at each word or phrase and redefine it to make the statement more precise. What is the real problem (Garmire, 2002) Usually brainstorming is done in this stage and is effective enough to reach to a reasonable conclusion.

3. Develop possible alternative solutions: Choosing the right design requires a creative

team effort to identify several possible solutions, and evaluate development of the preferred

option to confirm its feasibility before being formulated and made. (Eng, 2006) This enables engineers to study and analyse in detail each and every alternative solution with respect to its opportunities and drawbacks. Performance, cost control and complexity objectives must be considered and balanced during design evaluation.

Example: Financial concerns might make an engineering company choose rental over equipment purchase. Specific performance objectives, that the new system must perform online data processing may result in a complex network design for which control procedures must be established. Evaluating and selecting the best design involves a balance of system objectives that will best support organisational goals.

4. Select the best solution: Out of several possible alternates, only one is chosen in the

light of its effectiveness and accuracy. After choosing the final solution, the design specifications

are said to be frozen, as this formal step avoid cost overruns and missed user expectations.

5. Prototype development: Prototyping acts as an iterative approach to the engineering
design process. During each iteration, requirements and alternative solutions to the problems are identified and analysed, new solutions are designed, and a ...Show more

Summary

Engineering design is a process in which an understanding of the physical world, sometimes embodied in quantitative (i.e. mathematical) scientific models, is used to devise a recipe for constructing physical entities (e.g. machines, buildings) or information structures (e.g…
