Wire Harness Protector Layout for Stable Lead-Out Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire protectors for vehicles do not effectively regulate the route of electric wires, leading to potential interference with other components due to variability in cable tie tightening, which can cause the wires to collide with nearby components.
Innovation Solution
A wire harness protector with an accommodating portion and a lead-out portion that includes a wire fixing portion and a regulating wall portion, where the regulating wall portion is positioned at a different location from the wire fixing portion to control the electric wire's route and prevent interference with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire fixing portion with cable ties is used to fix electric wires, then the wires can be secured to the protector, but variability in tightening degree causes wires to potentially interfere with other components
Solution Approach 1:
The lead-out portion is divided into two distinct functional elements: a wire fixing portion for securing the wire and a regulating wall portion for controlling the wire route. This segmentation allows each element to perform its specific function independently, with the regulating wall providing additional constraint to prevent wire deviation and interference with surrounding components.
Solution Approach 2:
The regulating wall portion acts as an intermediary structure between the wire fixing portion and the surrounding environment. It provides a controlled pathway that guides the wire from the fixing portion to the lead-out port, preventing the wire from contacting or interfering with other components in the vicinity.
2Ease of manufacture
If cable ties are used for wire fixation, then wires can be bound to the protector, but the degree of tightening variability leads to unstable wire positioning
Solution Approach 1:
The lead-out portion is divided into two distinct functional elements: a wire fixing portion for securing the wire and a regulating wall portion for controlling the wire route. This segmentation allows each element to perform its specific function independently, with the regulating wall providing additional constraint to prevent wire deviation and interference with surrounding components.
Solution Approach 2:
The invention changes the geometric parameters of the lead-out portion by adding a regulating wall with specific dimensions (extending in a direction intersecting the lead-out port). This structural parameter change creates a physical constraint that stabilizes the wire route, compensating for the variability in cable tie tightening and ensuring consistent wire positioning.

AI summary
One aspect of the present disclosure provides a protector configured to suppress interference of an electric wire lead out from the protector with another component. A protector according to one aspect of the present disclosure includes an accommodating portion for accommodating an electric wire, and an intermediate lead-out portion for leading the electric wire accommodated in the accommodating portion to outside of the accommodating portion. The intermediate lead-out portion includes a wire fixing portion for fixing the electric wire, and a regulating wall portion for regulating a route of the electric wire at a different position from that of the wire fixing portion.
