2025 QUESTIONS AND ANSWERS
Design is a __________ process - ANS multistep
Design Process Steps - ANS 1. Identify
2. Conceptualize
3. Refine
4. Analyze
5. Prototype
6. Document
7. Produce
problem identification stage - ANS +STAGE 1*
the design engineer must address questions and answers from the customer's/client's
perspective and from the engineer's perspective.
life cycle of the product - ANS one of the design considerations
- how long will a designed product be used before it is no longer effective
green engineering - ANS design process where environmental concerns are considered
throughout the process, not just at the end, because an engineer's choices in the problem
definition stage often influence the overall environmental impact and life cycle of the product.

, most creative phase of the design process - ANS Concept generation
Sketching - ANS an integral way to develop concepts for a new design
concept generation starts - ANS with brainstorming, brainwriting, or a similar team meeting
where ideas are tossed around and discussed. Criticism is usually limited
end of the concept generation stage: - ANS team should have selected a few main ideas that
it will focus on for future refinement and analysis
weighted decision table - ANS common technique for selecting the final concept(s)
-All of the common attributes and desirable features of each concept are list in the first column.
A weighting factor for each feature/attribute is then established (e.g., using a scale of 0 to 10).
The various design options are listed in subsequent columns in a parallel fashion to the listed
features/attributes. The team then conscientiously scores each option for every
feature/attribute, each time applying the weighting factor to the score
stage 4: Design Evaluation and Analysis - ANS tests are conducted to determine mechanical
properties of objects or systems and their performance during simulated conditions
mass properties analysis report - ANS a useful document for evaluating and presenting the
static mechanical conditions of the design.
Further analysis of the design might include - ANS FEA of stress contours and deformation
Stage 5: Physical Prototyping - ANS Engineers can have the shop people build a *scale
mode*, an actual *true-size model*, or just a simple *mock-up concept model* that shows the
general physical appearance of the design.
recent years, modern technology has accelerated the production of prototype - ANS true
