Synthetic Resin Cable Guide with Torsional Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable protection and guide devices suffer from torsional instability, leading to shifting of side walls and lid pieces, and inability to open or close line accommodating passages, which affects operability and maintenance access.
Innovation Solution
A cable protection and guide device made of synthetic resin with integrally formed side and outer circumferential walls, featuring flexion restricting pieces, slits, concave and convex engagement mechanisms, and an openable outer wall, allowing for easy examination and providing strong torsional rigidity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional cable protection devices use separate side wall pieces and lid pieces, then assembly is simpler, but torsional rigidity is insufficient causing shifting and contact problems
Solution Approach 1:
The patent combines multiple separate components (side wall pieces and lid piece) into a single integrally molded accommodating body. This unification eliminates the shifting problems between separate parts while maintaining structural simplicity, directly resolving the contradiction between assembly simplicity and torsional rigidity.
2Stability of the object's composition
If line accommodating passages are sealed, then structural integrity is maintained, but examination of cables becomes impossible
Solution Approach 1:
The patent divides the accommodating body into a main body and a removable lid portion. This segmentation allows the lid to be detached for cable examination while the main body remains intact, resolving the contradiction between maintaining structural integrity and enabling cable accessibility.
Solution Approach 2:
The lid portion is designed to be removable and reattachable, transforming the static sealed structure into a dynamic one that can open for examination and close for protection, thus balancing structural integrity with operational accessibility.
3Strength
If wall thickness and material rigidity are increased to prevent torsion, then torsional stability improves, but the device becomes heavier and more complex
Solution Approach 1:
By integrating all wall portions into a single molded structure, the patent achieves torsional stability through structural unity rather than increasing wall thickness. This approach provides the necessary rigidity without adding excessive weight or complexity.

AI summary
The present invention provides a cable or the like protection and guide device which accommodates a cable or the like while allowing for examination of the cable. Smooth linear and flexional movement is achieved while not compromising the form stability of the cable accommodation space. Partial or local wear is suppressed. The device is made of a synthetic resin and accommodates a cable in a rectangular cable accommodating space. The accommodating space is surrounded by the outer circumferential wall portion, which is openable, a pair of side wall portions, and an inner circumferential wall portion. Inserting protrusion mechanisms, engagement mechanisms, slits, opening windows and flexion restricting piece portions contribute to the stability and usefulness of the device.
