## Functional fixedness

A familiar label can hide a useful property.

### Use when

- You need to examine whether the function you need differs from a familiar object’s usual purpose.

### Explanation

Functional fixedness is difficulty seeing an object beyond its customary use. A box can be more than packaging; its flat surface, weight or shape may matter to a new problem. The useful move is to describe the function you need before searching only for the tool normally sold for it.

State the required property: hold, separate, support, mark or contain. Inspect available objects for that property, then check whether the alternative use is safe and adequate.

### Example

A light draft keeps moving your paper pattern. You look for a paperweight while a closed notebook sits beside you. The missing function is simply safe, sufficient weight.

### Check

Am I rejecting this object because it cannot do the job, or because that is not its usual job?

### Limits

- An unusual use is not necessarily a good one. Do not improvise load-bearing, electrical or protective equipment from this example.

### Evidence and sources
