Reversible Cable Pressing Structure for Multi-Thickness Cable Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable pressing blocks are limited in versatility due to fixed size specifications, making them ineffective for cables of varying thicknesses, leading to issues of looseness or detachment when cables are pulled.
Innovation Solution
A cable pressing structure with a main portion and two connecting portions that can be detachably connected to a carrying base, featuring different cable pressing portions on each side to accommodate cables of varying thicknesses, allowing for adjustable installation states to accommodate cables of different specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing block with fixed size specification is used, then the cable can be fixed with sufficient pressing force, but the pressing block can only accommodate cables of one thickness specification, resulting in poor versatility
Solution Approach 1:
The pressing block is divided into multiple pressing surfaces with different size specifications. Each pressing surface can independently contact the cable, allowing the pressing block to adapt to cables of various thicknesses while maintaining sufficient pressing force through the segmented pressing areas
Solution Approach 2:
The pressing block is designed with multi-functionality by incorporating pressing surfaces of different size specifications on its sides. This allows a single pressing block to serve multiple cable thickness specifications, transforming it from a single-purpose component to a universal fixing device that can handle various cable sizes
2Adaptability or versatility
If the pressing block size is increased to accommodate thicker cables, then versatility improves, but the pressing force distribution becomes insufficient for thinner cables
Solution Approach 1:
Different sides of the pressing block are equipped with pressing surfaces of different size specifications, creating local quality variations. This allows the pressing block to apply appropriate pressing force distribution for each cable thickness - larger pressing surfaces for thicker cables and smaller pressing surfaces for thinner cables, ensuring reliable fixation across all cable sizes
