Partial trimming

Partial trimming is redistributing some useful functions of a system component to other components, while leaving the component in the system for performing remaining functions.

Overview

In simple terms, partial trimming means that the component remains in the system, but redistributing some of its useful functions to other components leads to its “unloading.” This often allows for reducing the component’s cost, size, weight etc.

The picture below presents an example. Consider a system component (component 1) that performs three useful functions but is large and heavy. By delegating two of its functions to other component (component 3), it can be made smaller and lighter. Component 1 remains in the system, but after partial trimming, it performs only one function, and its key disadvantages – size and weight – are eliminated.

Partial trimming can be applied to all engineering systems – both devices and processes. Just like with typical trimming, the redistribution of functions follows specific trimming rules, accordingly for devices and processes.
