Protector-equipped Wire Harness Sliding Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing protector designs for electrical wires have a through hole that allows the lock portion of the clamp to protrude outward, limiting the area where the protector can be disposed and risking contact with surrounding components.
Innovation Solution
A protector-equipped wire harness with a plate-shaped portion, slide supporting portion, and a receiver that includes a slidable member and attachment member, which are fixed together without the need for a conventional clamp, allowing the slidable member to slide and be locked in place to prevent protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a through hole is used to fix the clamp to the protector, then the clamp can be securely attached, but the lock portion protrudes outward by a large length, limiting the disposal area and risking contact with surrounding components
Solution Approach 1:
The invention transitions from a through-hole attachment method (one-dimensional penetration) to a surface-mounted attachment method using a receiver on the protector surface. The slidable member engages with the receiver through sliding motion, achieving secure attachment without protruding through the protector surface, thus resolving the contradiction between attachment security and disposal area.
2Reliability
If a conventional clamp with lock portion is used, then the electrical wires can be fixed to the protector, but the lock portion protrudes outward by a large length, increasing the space required for the wire harness
Solution Approach 1:
The invention merges the attachment function into the protector body by integrating a receiver directly on the protector surface. The slidable member of the clamp engages with this receiver, combining the protector and attachment mechanisms into a unified structure that reduces the overall volume and eliminates the need for a protruding lock portion.
3Reliability
If a through hole is used for attachment, then the clamp can be fixed to the protector, but the structure becomes more complex and the installation process becomes more difficult
Solution Approach 1:
The invention replaces the static through-hole attachment with a dynamic sliding mechanism. The slidable member can move along the receiver during installation and then locks into place, providing both ease of installation and secure attachment. This dynamic approach simplifies the structure compared to rigid through-hole configurations.

AI summary
A protector-equipped wire harness includes: an electrical wire; a protector that includes a plate-shaped portion, a slide supporting portion formed so as to extend inward in a first direction from one edge portion of the plate-shaped portion, and a receiver that is provided on a far side with respect to the slide supporting portion, the protector being disposed so as to cover at least a portion of an outer circumferential surface of the electrical wire; and an attachment member that includes a slidable member that includes a slidable portion supported by the slide supporting portion so as to be slidable in the first direction, the attachment member being provided with a harness-related component or a component attachment portion for a harness-related component. The protector and the attachment member are fixed to each other in a state where the slidable member of the attachment member is in contact with the receiver.
