Concern:
Using a nail that is too short will not result in the required performance, and one that is too long may protrude (become visible or penetrate another object).
Countermeasure:
: The heads of these pneumatic nails have different colors to correspond to different lengths and diameters. This makes it easy for workers to grab the right nails (less likely they will confuse sizes), and reorder the color they need.
It also makes it possible for workers and inspectors to see and verify whether or not nails were insta
Limitation:
| Triz Description | 32.1: Change the color of an object or its external environment. |
