Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wiring modules are difficult to transport and position along a predetermined route during assembly in vehicles due to lack of flexibility and rigidity in their design.

Innovation Solution

A wiring module with distinct sections of varying bendability and rigidity, including a first section with high rigidity, a second section with medium bendability, and a third section with high flexibility, allowing for easy folding and unfolding along a predetermined route.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wiring module uses uniform rigidity throughout, then structural stability is maintained, but ease of transportation and positioning deteriorates due to inability to fold

Engineering Contradiction:

Improveease of transportationVSAvoidstructural stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The wiring module employs different rigidity levels in different sections: the first section has high rigidity for structural stability, while the second section has low rigidity for easy folding and positioning. This local differentiation of mechanical properties allows the wiring module to be both stable during installation and easy to transport when folded.

AI summary

A wiring module includes: a wiring member including a first section, a second section, and a third section as sections different from each other along an extension direction; a first rigid member attached to the first section; and a second rigid member attached to the second section. A portion including the first section and the first rigid member is a first portion, a portion including the second section and the second rigid member is a second portion, and a portion including the third section is a third portion. The third portion has bendability to be able to be folded. The second section is more bendable than the first portion, and is less bendable than the third portion.
