Wire Harness Protector With Rotatable Branch For Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protectors for wire harnesses on vehicles face challenges in improving assembling workability, particularly in managing and securing branched wiring materials effectively.
Innovation Solution
The protector design includes a main body unit, movable and fixed branch units, holding units, rotation support, and fixing units that allow for the insertion, rotation, and securement of main and branched wiring materials along different directions, enhancing assembly efficiency and structural integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate protection units with multiple lids and locking units are used to protect wire groups bending in multiple directions, then the protection coverage is improved, but the assembling workability deteriorates
Solution Approach 1:
The patent combines multiple separate protection units into a single integrated protector body with multiple space portions. Instead of using separate protection units for different wire group directions, the invention creates one unified structure that accommodates wire groups bending in multiple directions through internally divided spaces, thereby improving assembling workability while maintaining comprehensive protection coverage.
Solution Approach 2:
The protector body is segmented into multiple space portions (first space portion, second space portion, etc.) that are communicatively connected. Each space portion is designed to accommodate wire groups in specific directions, allowing the single integrated structure to provide targeted protection for different wire routing configurations without requiring multiple separate units.
2Stability of the object's composition
If a rigid fixed structure is used to position branched wiring materials, then the structural stability is improved, but the adaptability to different wiring configurations deteriorates
Solution Approach 1:
The patent incorporates a movable branch unit that can rotate relative to the main body unit through a rotation support unit. This dynamic capability allows the branch unit to adapt to different wiring configurations and directions while maintaining structural stability when fixed at the desired position using the fixing unit, thus resolving the contradiction between rigidity and adaptability.
Solution Approach 2:
The movable branch unit with rotation capability serves multiple functions: it can accommodate wiring materials in different directions, adapt to various branching angles, and provide stable positioning when fixed. This multi-functional design eliminates the need for multiple fixed structures for different wiring configurations.

AI summary
A protector applied to a wire harness includes a main body that has a main space formed along a first direction and into which a conductive main wiring material can be inserted; a movable branch that has a movable branch space communicated with the main space and into which a movable branch wiring material branched from the main wiring material can be inserted; a holding unit that can hold the movable branch wiring material inserted into the movable branch space to the movable branch; a rotation support unit that rotatably supports the movable branch relative to the main body, at a wiring position where the movable branch space is placed along a second direction and at a use position where the movable branch space is placed along a third direction; and a fixing unit that can fix the movable branch to the main body at the use position.
