MAE 1351 Exam 1 Review1. Stages of the Design Process:
1)Identify
2)Conceptualize
3)Refine
4)Analyze
5)Prototype
6)Document
7)Produce
8)Life Cycle

2. Problem Identification (Design process, STEP 1): the design engineer must
address questions and answers from the customer's/client's perspective and
from the engineer's perspective.
-may involve generating new ideas, or improving an existing design
-may use MARKET SURVEY to determine specs of the project (useful, market
appeal, produce-able, profit)
-take into consideration the LIFE CYCLE of the product
-Environmental considerations (GREEN ENGINEERING) and disposal of a
product must be considered
3. market survey (problem identification - step 1): may demonstrate that the
new product or system is useful, has market appeal, is producible with today's
technology, and will make a profit for the company supporting the design effort
4. Life Cycle (of product) (step 1): When a product is designed, one of the
design considerations is how long will it be used before it is no longer effective
5. Green Engineering (step 1): Environmental considerations and disposal of a
product must be considered throughout the design process. In the design
process called ________________ __________________, 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
6. Concept Generation (Design process, STEP 2): -most creative phase of the
design process
-use methods for creative thinking and concept generation
, MAE 1351 Exam 1 Review
-criticism of ideas is limited in this phase (want to come up with as many ideas as
possible)
-At the end of the concept generation stage, the team should have selected a few
main ideas that it will focus on for future refinement and analysis. -Sketching is an
integral way to develop concepts for a new design
7. Concept Selection and Refinement (Design process, STEP 3): Once a few
quality concepts have been identified, the design team must converge on *one
or two final concepts to further explore* in the design process.
-use a WEIGHTED DECISION TABLE to help make these decisions
-initial concepts may need to be refined before final decision is made
-REFINEMENT will likely include the development of 3-D computer models for
defining geometry not accurately expressed in the concept sketches.
8. Weighted Decision Table (step 3): A common technique for selecting the final
design concept(s)
HOW TO SET UP:
-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
-Adding all of the scores for individual attributes yields a final "bottomline" number
that can be used to select the highest-ranked option
9. Refinement (step 3): will likely include the development of 3-D computer
models for defining geometry not accurately expressed in the concept sketches.
(used in step 3 of the design process)
10. Design Evaluation and Analysis (Design Process, STEP 4): -the selected
concept is further analyzed by any number of numerical methods.
-*The tests are conducted to determine mechanical properties of objects or
systems and their performance during simulated conditions.*
