Retainer Member Claw Locking for Noise Reduction Cable Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing noise reduction members with cables suffer from high costs, limited cable winding capacity, and difficulty in repositioning or removing the noise reduction members, as they require complex arrowhead fixing portions or increased size for clamping structures.
Innovation Solution
A retainer member with multiple retaining portions, each equipped with a claw for locking the cable, a suspension portion, and a placement portion, allowing for secure retention and easy mounting of noise reduction members wound with cables, while a cover part and fixing portion ensure stability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an arrowhead fixing portion is formed at the cover of the noise reduction member and fixed in a hole at the mount subject, then the noise reduction member can be fixed in position, but the manufacturing cost increases and the operation of removing or repositioning becomes difficult
Solution Approach 1:
The retainer member is divided into a cover and a separate retaining portion, allowing the retaining portion to be detached and repositioned independently while the cover remains fixed, thus enabling easy removal and reinstallation without affecting the overall structure
Solution Approach 2:
The retaining portion is extracted as a separate component from the cover, allowing it to be independently installed, removed, and repositioned. This separation eliminates the need for complex arrowhead fixing portions integrated into the cover, reducing manufacturing cost and structural complexity
2Reliability
If an inside-periphery retaining portion is used to clamp the noise reduction member, then the noise reduction member can be locked in position, but the cable winding capacity is limited and the member size must be increased for long cables
Solution Approach 1:
The retaining portion is positioned at the end of the cable in the axial direction rather than on the inside periphery, utilizing the cable's endpoint to provide locking. This dimensional shift allows the noise reduction member to maintain a compact size while still achieving reliable locking, and enables longer cables to be wound without increasing the member volume
3Reliability
If the noise reduction member is clamped between outside-periphery and inside-periphery retaining portions, then the noise reduction member can be locked, but the number of cable windings is limited
Solution Approach 1:
The inside-periphery retaining portion is removed entirely, and the retaining function is transferred to a separate retaining portion positioned at the cable end. This extraction eliminates the space constraint imposed by the inside-periphery structure, allowing increased cable winding capacity while maintaining locking stability through the external retaining mechanism

AI summary
In a retainer member for retaining a noise reduction member, a retaining portion for retention of a noise reduction member wound with a cable is provided with a claw for locking the cable wound on the noise reduction member.
