Solution Overview
Problem
Electric cables installed in inclined and vertical regions tend to slip down due to their weight and thermal expansion, leading to degraded performance and excessive stress on supporting structures.
Innovation Solution
An apparatus comprising an anchor plate, bell mouth, guide supporting bars, elasticity controllers, and spring cleats that work together to maintain cable tension, preventing slipping by compressing or elongating in response to thermal changes and dispersing forces across multiple controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cables are installed in inclined and vertical regions, then cable routing flexibility is improved, but cable slipping down occurs due to weight and thermal expansion
Solution Approach 1:
The patent introduces an elasticity controller as an intermediary component between the cable and the supporting structure. This elasticity controller acts as a mediator that absorbs the harmful effects of cable weight and thermal expansion through elastic deformation, while maintaining reliable cable positioning. The elasticity controller deforms elastically in response to cable tension changes, preventing the cable from slipping down while allowing routing flexibility in inclined and vertical regions.
Solution Approach 2:
The patent utilizes parameter changes in the elasticity controller's physical state to resolve the contradiction. The elasticity controller changes its deformation parameter in response to varying cable tension caused by thermal expansion and contraction. By allowing the controller to dynamically adjust its elastic deformation, the system maintains cable positioning stability while accommodating the cable's natural movement due to temperature changes and weight.
2Reliability
If cables are fixed rigidly to prevent slipping, then cable positioning stability is improved, but excessive stress is delivered to supporting structures
Solution Approach 1:
The patent applies beforehand cushioning by positioning the elasticity controller in advance between the cable and the supporting structure. This elasticity controller serves as a cushioning element that absorbs and mitigates the stress generated by cable weight and thermal expansion before it reaches the supporting structures. The controller's elastic properties allow it to deform and absorb energy, preventing excessive stress transmission to the anchor plate and other supporting components.
3Stress or pressure
If elasticity controllers are used to absorb thermal tension, then stress on structures is reduced, but device complexity increases
Solution Approach 1:
The patent employs an elasticity controller that functions as a flexible element to reduce stress on supporting structures. This flexible component allows the system to accommodate thermal expansion and contraction of the cable without requiring complex rigid mechanical systems. The elasticity controller's flexible nature enables it to deform and absorb stress while maintaining a relatively simple overall apparatus structure, avoiding the need for complex adjustable mechanisms or multiple components.
