[SECTION 1: Questions 1–9] – Engineering Design Process (Define, Ideate, Prototype,
Test, Iterate)
Q1: A student team working on a water bottle design skips the "Define" phase and
immediately begins brainstorming solutions. According to the engineering design process,
what is the most likely consequence of this approach?
A. The team will save time and still produce an effective final product because ideation is
the most important phase.
B. The team may develop creative solutions that do not address the actual user needs or
constraints identified in the problem statement.
C. The team will naturally discover the problem definition during the prototyping phase,
making the Define phase redundant.
D. The team will produce a solution that is guaranteed to pass all testing criteria because
they focused on creativity first.
B. The team may develop creative solutions that do not address the actual user needs or
constraints identified in the problem statement. [CORRECT]
,Correct Answer: B
Rationale: The Define phase establishes the problem statement, constraints, criteria, and
user requirements that guide all subsequent phases. Skipping it means the team lacks a
clear target, so even creative solutions may miss the mark entirely—a common
misconception in EGR 1400. Choice A is wrong because saving time at the cost of
direction leads to wasted effort. Choice C is wrong because prototyping without a defined
problem produces random iterations, not insight. Choice D is wrong because testing
criteria derive from the Define phase; without it, there is no benchmark for success. This
aligns with ABET Criterion 3 (design) which emphasizes problem definition as
foundational.
Q2: During the "Iterate" phase of the engineering design process, a team discovers that
their prototype fails to meet the weight requirement specified in the Define phase. What
should the team do NEXT?
A. Abandon the current design entirely and start over from the Ideate phase with a
completely new concept.
B. Accept the failure and submit the prototype as-is, documenting that it did not meet all
criteria.
C. Return to an earlier phase (likely Ideate or Prototype) to modify the design, then retest
with the updated version.
D. Change the original problem statement to match what the prototype can actually do.
C. Return to an earlier phase (likely Ideate or Prototype) to modify the design, then retest
with the updated version. [CORRECT]
,Correct Answer: C
Rationale: Iteration means cycling back to earlier phases to refine the design based on test
feedback—this is the core of the spiral/iterative design model taught in EGR 1400. Choice
A is wrong because iteration does not require a full restart; targeted modifications are
more efficient. Choice B is wrong because engineering design requires meeting criteria,
not accepting failure. Choice D is wrong because changing the problem to fit the solution
violates the purpose of the Define phase and ABET design standards. Real-world
engineers iterate constantly (e.g., SpaceX rocket redesigns).
Q3: Which of the following best describes the purpose of the "Ideate" phase in the
engineering design process?
A. To build a full-scale working prototype of the best concept selected by the team.
B. To generate a large quantity of diverse potential solutions without immediate judgment
or evaluation.
C. To finalize the engineering drawings and specifications for manufacturing.
D. To conduct a formal cost-benefit analysis of all possible solutions.
B. To generate a large quantity of diverse potential solutions without immediate judgment
or evaluation. [CORRECT]
Correct Answer: B
Rationale: Ideation emphasizes divergent thinking—generating many ideas without
criticism to maximize creativity, following brainstorming rules from EGR 1400. Choice A is
wrong because prototyping comes after ideation. Choice C is wrong because final
drawings occur after testing and iteration. Choice D is wrong because economic analysis
, typically occurs in later phases or during evaluation. This reflects the NSPE emphasis on
creative problem-solving and aligns with standard design textbooks like Dieter & Schmidt.
Q4: A team tests their prototype and finds that it works perfectly under laboratory
conditions but fails when used in the real-world environment the customer described.
Which phase of the design process most likely failed to adequately address this issue?
A. The Ideate phase, because the team did not generate enough ideas.
B. The Define phase, because the team did not fully understand the real-world operating
conditions and user constraints.
C. The Prototype phase, because the prototype was built too quickly.
D. The Test phase, because the team should have tested more times in the lab.
B. The Define phase, because the team did not fully understand the real-world operating
conditions and user constraints. [CORRECT]
Correct Answer: B
Rationale: The Define phase requires identifying all constraints, including environmental
and use conditions. If the team only considered lab conditions, they failed to capture the
true problem. Choice A is wrong because having more ideas would not fix a
misunderstood problem. Choice C is wrong because prototype quality is not the
issue—the requirements were incomplete. Choice D is wrong because lab testing cannot
reveal failures caused by unanticipated real-world conditions. This is a classic EGR 1400
exam scenario testing understanding of requirements gathering per ABET Criterion 1.
Q5: In the engineering design process, why is the "Test" phase considered critical before
moving to full production?
