Simple Design Problems
Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost
What a learner can do afterwards
- Define a design problem by describing the need or want it addresses
- Specify at least two criteria for a successful solution (e.g. must hold X weight, must cost less than Y)
- Identify constraints such as available materials, time limits, or cost
The lesson
Every design starts with a problem. A problem is a need or a want, something people wish they had or wish worked better. Before you build anything, you write that need down in one clear sentence.
At Lincoln School, kids wobble when they cross the walkway between two buildings, especially when more than one person crosses at once. The need: a steadier bridge so everyone can cross safely.
Once you know the need, you write criteria: exact rules that tell you whether your design worked. A good criterion uses a number, like 'must hold 5 blocks without bending.'
You also need constraints: limits on materials, time, or cost. If you only have 20 straws, one roll of tape, and 15 minutes, your design has to work within those limits, not with unlimited supplies.
A design problem names the need, gives at least two criteria for success, and lists the constraints on materials, time, or cost.
