Below are sample questions representative of the exercises included on this worksheet and related 8.124 Generate, Compare and Optimize Solutions skill assessments:

Problem 1Difficulty: Mastery

A capstone team designs a portable phone charger. It must charge 50 percent in 30 minutes, weigh under 180 g, cost under $18, and stay below a safe temperature. Prototype A charges 55 percent, 210 g, $16, safe. Prototype B charges 48 percent, 160 g, $14, safe. Prototype C charges 52 percent, 170 g, $19, safe. Which next step best uses evidence to compare and improve the prototypes?

ASelect Prototype A because it charges fastest and ignore mass.

BSelect Prototype B because it is cheap and light and ignore charge amount.

CStop the project because all prototypes are equally successful.

DUse evidence to iterate, such as reducing A's mass or improving B's charging rate, because no prototype meets all criteria and constraints.

Solution & Explanation:Each prototype fails at least one requirement, so the team should use the evidence to target a redesign rather than choose a noncompliant option.

Problem 2Difficulty: Mastery

A team comparing bike-lock designs has data on cutting resistance and price, but no data on how long each lock takes to use. The criteria include security, affordability, and quick locking. What should the team do next?

AMeasure locking and unlocking time for each design under the same conditions.

BChoose the strongest lock immediately.

CIgnore quick locking because it is harder to test.

DUse color as a substitute for time data.

Solution & Explanation:Since quick locking is one criterion, the team needs comparable time data before making a balanced decision.

Problem 3Difficulty: Mastery

A portable speaker design is loud and cheap but fails a water-resistance constraint. Which response best handles the conflict?

AChoose the design because loudness is exciting.

BRevise the housing seal or materials and retest loudness, cost, and water resistance.

CRemove the water-resistance constraint without explaining why.

DStop testing after the loudness result.

Solution & Explanation:The design has strengths but violates a constraint, so the team should target the waterproofing weakness and retest all key factors.
