How to Think Like an Inventor in 20 Minutes

Almost every invention you can name started with somebody getting annoyed. The zipper exists because shoelaces kept coming undone. Post-it notes came out of a glue that was too weak to be useful. Velcro came from a guy walking through a field and picking burrs off his dog.

None of them sat down planning to invent something. They noticed something that bugged them and asked one question: what if there were a better way to do this?

No lab, no special kit, no permission needed. Four steps and about twenty minutes is enough.

1. 1

   Find a problem

   Go small and annoying. A door that keeps swinging shut. A charger that never stays plugged in. A zipper that snags on the same tooth every time. Tiny frustrations beat huge ones, because you can actually test a fix for a tiny one.

2. 2

   Sketch a solution

   Draw the fix. Even a lumpy shape on notebook paper counts. You are not making art. You are making your idea specific enough that someone could argue with it.

3. 3

   Build a rough prototype

   Whatever is nearby works: paper, tape, cardboard, rubber bands. It does not have to look good. It has to be testable.

4. 4

   Test it

   Now try to break it. If it survives the first try easily, your test was too soft. Find the weak spot. Congratulations, that is your next problem.

Step one trips up most students, and not because the world is short on problems. It is because we all get really good at ignoring small annoyances instead of noticing them.

• What takes way longer than it should?
• What breaks more often than it should?
• What are you always holding in some awkward way?
• What do you do every single day that you wish you did not have to?

Then pick the smallest one on your list. A problem you can hold in your hands is far easier to invent for than one the size of a city.

A sketch is not a drawing. It is a decision. The second you put it on paper you have to commit: the hinge goes here, this side opens, the grip is about this wide.

That commitment is what makes the idea testable. Skip the sketch and you just adjust as you go, which works, but it is slower and you never notice when reality drifted away from your plan. With a sketch, you can see the gap.

A prototype is the fastest version of your idea that you can actually test. It is not a product. It is not supposed to be pretty. Its only job is to teach you something you did not already know.

• Tape instead of glue, because you will be pulling it apart in five minutes
• Use the simplest shape that tests the one thing you care about
• Build to answer one question: does the hinge hold? does it fit? does it slide?
• If it takes more than 10 minutes, you are overbuilding it
