Elastic Wire Guide for Slide Door Auto-Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wire routing apparatuses face challenges in maintaining reliability and preventing damage when trampled, as they often experience difficulty returning to their original state after being displaced.
Innovation Solution
An electrical wire routing apparatus featuring a stretchable elastic member between the wire guide and the vehicle body or movable body, guided by a bracket that allows the wire guide to bend and return to its original position using an elastic restoring force, preventing excessive stress and facilitating automatic recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical wire guide is made flexible to allow bending displacement, then adaptability to motion is improved, but reliability when trampled deteriorates
Solution Approach 1:
The electrical wire guide is designed with multiple linking members that can dynamically change their configuration. The linking members are capable of rotating relative to each other, allowing the wire guide to adapt its shape during motion while maintaining structural integrity. This dynamic structure enables the wire guide to bend and return reliably without permanent deformation.
Solution Approach 2:
The electrical wire guide is divided into multiple linking members connected by linking belts. This segmentation allows each member to move independently while maintaining overall coherence. When trampled, the linking members can separate and rotate to absorb stress, then return to their original positions due to the elastic restoring force of the linking belts, ensuring reliable returning motion.
2Strength
If the linking members are allowed to separate to prevent damage, then strength protection is improved, but manufacturing precision deteriorates
Solution Approach 1:
The elastic linking belts provide a feedback mechanism through their elastic restoring force. When linking members separate due to trampling, the stretched linking belts generate a restoring force that automatically guides the members back to their original linked positions. This feedback ensures that even after separation for stress protection, the manufacturing precision of the linking positions is restored.
Solution Approach 2:
The electrical wire guide structure is designed to self-correct its configuration. The elastic linking belts automatically pull the linking members back to their proper positions after separation, without requiring external intervention. This self-service mechanism maintains linking position accuracy while allowing temporary separation for stress resistance.

Function Achieved in This Case
The solution effectively distributes stress and ensures the electrical wire guide can automatically return to its original state, enhancing reliability and preventing damage from trampling, while allowing flexible selection of elastic member materials and shapes for stability.
Implementation Method 1
a stretchable elastic member (60) that connects the bracket (40) and the electrical wire guide (10)... the electrical wire guide can automatically return to the original state due to the electrical wire guide being guided by the bracket while receiving an elastic restoring force of the elastic member

AI summary
An electrical wire routing apparatus with high reliability of a motion returning to the original state after being trampled on. The electrical wire routing apparatus includes an electrical wire guide into which an electrical wire routed between a vehicle body and a movable body such as a slide door is insertable and that interlocks with a motion of the slide door, a stretchable elastic member that is installed between the electrical wire guide and the vehicle body, between the electrical wire guide and the slide door, or partway through the electrical wire guide, and a bracket for guiding a displacement motion of the electrical wire guide when the elastic member stretches or shrinks.
