Interchangeable Parts: The Key to Mass Production and Modular Design

Interchangeable parts are components that can be swapped out with other identical components without affecting the overall function of a system. This concept was first introduced by Eli Whitney in the late 18th century and has since become a fundamental principle of mass production and manufacturing.

In a system that uses interchangeable parts, each component is designed to be identical to every other component of the same type. This means that any one component can be replaced with another identical component without affecting the performance or functionality of the system as a whole. This makes it easier to repair, maintain, and upgrade systems, as well as to produce them in large quantities at a lower cost.

Interchangeability is a key principle of modular design, where components are designed to be easily removable and replaceable with other components of the same type. This allows for greater flexibility and customization in system design, as well as easier maintenance and upgrades.
