Deformable Cable Noise Absorber Fixing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for absorbing electrical noise on cables often fail to securely fasten to cables of varying thickness and flexibility, particularly those with thick, solid wires which are less flexible than cables with many thin strands.
Innovation Solution
A clamshell housing with deformable fixing means that can accommodate different cable sizes and flexibilities by allowing deformation in both the longitudinal and transverse directions, featuring fixing edges that form a slot for secure attachment, and L-shaped webs connected to the housing end faces for enhanced stability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid fixing means with teeth or clamps are used to prevent housing from slipping on the cable, then the fixing strength is improved, but the adaptability to different cable flexibilities deteriorates
Solution Approach 1:
The fixing means is designed to be deformable, allowing it to adapt its shape based on the cable's flexibility and thickness. The deformation capability enables the same fixing structure to work effectively on both rigid cables (with thick solid wires) and flexible cables (with many thin strands), resolving the contradiction between fixing strength and adaptability.
Solution Approach 2:
The fixing means can change its physical parameters (shape, deformation degree) in response to different cable characteristics. This parameter adaptability allows the fixing structure to maintain optimal fixing strength across various cable types without requiring multiple different fixing designs.
2Reliability
If the fixing means is made rigid to provide sufficient reaction force, then the fixing reliability is improved, but the ability to accommodate different cable thicknesses deteriorates
Solution Approach 1:
The fixing means incorporates deformable elements that can dynamically adjust to different cable thicknesses while maintaining reliable fixing. The deformation allows the structure to conform to various cable diameters, ensuring consistent fixing reliability across different cable sizes.
Solution Approach 2:
The fixing means utilizes flexible structural elements that can bend and deform to accommodate different cable thicknesses. This flexibility enables the same fixing structure to reliably secure both thin and thick cables without compromising fixing reliability.
3Strength
If the housing is designed to fit tight on thin flexible cables, then the fixing strength is improved, but it cannot accommodate thick rigid cables without damaging insulation, worsening the harmful effects on the cable
Solution Approach 1:
The deformable fixing means can adjust its compression force based on the cable's flexibility and thickness. For thick rigid cables, the structure deforms to reduce compression, preventing insulation damage. For thin flexible cables, it maintains sufficient compression for secure fixing, thus resolving the contradiction between fixing strength and prevention of harmful effects.
Solution Approach 2:
The fixing means changes its physical state and deformation degree according to the cable characteristics. This parameter adaptation ensures that the compression force and contact pressure are optimized for each cable type, preventing insulation damage on rigid cables while maintaining adequate fixing strength on flexible cables.

AI summary
A device for absorbing the electrical noise in cables contains a housing with a feed-through for a cable, which in the fastened position projects out of both end-faces of the housing. Externally on each of the end faces there are two strips which between them form a slot, and these strips form fixing edges bounding the slot. The strips are connected to the end-faces of the housing in such a way that they are able to turn away from one another, so that their fixing edges can be moved further away or nearer along the longitudinal direction of the cable. By this means the breadth of the slot can be adapted to the flexibility and/or the diameter of the cable.
