Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jigs for protecting wire harnesses during passage through vehicle panels require cumbersome manual manipulation for attachment and detachment, increasing operational complexity and cost.
Innovation Solution
A jig with a harness protective part that is enlargeable and reduceable, featuring a pair of tab operating parts and a spring member to facilitate easy attachment and detachment, ensuring stable mounting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer shape of the jig is reduced by increasing the overlapping amount, then the jig can be attached to and detached from the periphery of the through hole, but the technician must use both hands to compress the trumpet-shaped jig while squeezing the outer circumferential surface, reducing workability
Solution Approach 1:
The jig is designed with a spring member that automatically restores the harness protective part to its initial expanded state after it has been compressed for attachment or detachment. This self-restoring mechanism eliminates the need for manual restoration operations, allowing single-handed operation and significantly improving workability during attachment and detachment cycles
Solution Approach 2:
The harness protective part is designed to be dynamically changeable between an expanded initial state and a compressed reduced state. The spring member enables this dynamic transformation, allowing the jig to adapt its shape as needed for attachment, operation, and detachment without requiring complex manual manipulation for state transitions
2Object-affected harmful factors
If magic pile is used to protect the wire harness, then the wire harness is protected from damage, but the processes of wrapping and removing and then collecting and reusing the magic pile are troublesome and increase costs
Solution Approach 1:
The invention replaces the disposable magic pile with a durable, reusable jig that has a harness protective part. The jig can be attached and detached multiple times through the spring-restored compression mechanism, eliminating the need for continuous wrapping and collection of magic pile, thereby reducing operational complexity and costs while maintaining protection functionality
Solution Approach 2:
The spring member automatically restores the harness protective part to its protective expanded state, ensuring continuous protection readiness without manual intervention. This self-service mechanism eliminates the repetitive manual operations required for magic pile wrapping and repositioning, significantly reducing operational complexity
