Elastic Wiring Attachment With Rigid Catch for Higher Removal Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic attaching members in automotive wiring systems do not effectively increase the force required for removal, leading to potential detachment issues under vibration and stress.
Innovation Solution
An elastic attaching member with a high rigidity part embedded within and protruding from an elastic main body, which catches on the attachment target member, inhibiting inward deformation and increasing the removal force, while also providing a guide surface and removal stopping surface for secure attachment and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic attaching member is used to attach an attachment component to an attachment target member, then the attachment is flexible and easy to install, but the force necessary for removal is insufficient under vibration and stress
Solution Approach 1:
The attaching member combines an elastic main body part made of elastic material with a high rigidity part made of rigid material. This composite structure allows the elastic portion to provide flexibility and ease of installation, while the rigid protruding part provides high removal force resistance through engagement with the attachment target member.
Solution Approach 2:
The attaching member is divided into functionally distinct segments: an elastic main body part for flexible attachment and a high rigidity protruding part for secure engagement. This segmentation allows each part to optimize its specific function - the elastic part absorbs deformation while the rigid part maintains engagement force.
2Reliability
If the elastic attaching member is designed to increase removal force, then attachment reliability improves, but the structure becomes more complex
Solution Approach 1:
The high rigidity part is integrated within the elastic main body part, with the rigid portion embedded in the elastic material. This merging creates a unified attaching member structure that combines both functional requirements without requiring separate components or complex assembly mechanisms.
Solution Approach 2:
By using composite materials with different rigidity characteristics in a single integrated structure, the design achieves high attachment security through the rigid protruding part while maintaining relative structural simplicity through the unified elastic-rigid composite form.
3Force
If a high rigidity part protrudes from the elastic main body, then removal force increases, but the attaching member may catch on surrounding components
Solution Approach 1:
The high rigidity part is positioned specifically at the protruding portion that engages with the attachment target member, while the main body remains elastic. This localized rigidity provides the necessary removal force at the engagement point without requiring the entire attaching member to be rigid, reducing interference with surrounding components.

AI summary
An object is to be able to increase the force necessary for removal in a state where an elastic attaching member is attached to an attachment target member as much as possible. An elastic attaching member for attaching an attachment component to an attachment target member includes an elastic main body part formed from an elastic material and a high rigidity part formed from a material more rigid than the elastic main body part, the elastic main body part covering at least part of the attachment component, part of the high rigidity part being embedded in the elastic main body part, and another part of the high rigidity part protruding outward from at least part of the elastic main body part to form a protruding part.
