2 lessons
4 quiz questions
Lesson 1: Define and Evaluate
Define design problems and compare competing solutions.
Learning goals
- Define criteria and constraints.
- Develop multiple solutions.
- Evaluate solutions systematically.
Problem definition
A strong engineering problem statement includes the need, criteria for success, constraints, and relevant scientific principles.
Competing solutions
Engineers compare solutions using evidence. Trade-offs are common because improving one feature can reduce another.
Lesson 2: Test, Analyze, and Optimize
Use data from tests and models to improve designs.
Learning goals
- Plan fair tests.
- Analyze data from prototypes.
- Use models to optimize solutions.
Testing prototypes
Prototype tests provide data about how well a design meets criteria. Tests should be controlled so results are meaningful.
Optimization
Optimization means improving a solution by using data, comparing trade-offs, and changing design features.
