Cable Support Frame Control to Reduce Bending Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing support apparatuses for large structures like telescopes and antennas face challenges in moving the movable-side member with required accuracy due to rolling friction between the protective frame connected body and the supporters.
Innovation Solution
A support apparatus with a protective frame connected body, upper and lower supporters, detection sensors, and an upper supporter opening/closing controller that moves the supporters to avoid contact with the bending portion, reducing friction by dynamically adjusting their positions based on object detection information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective frame connected body is supported by rollers on supporters, then the cable guide can be supported at different positions and sagging can be prevented, but rolling friction is generated that reduces movement accuracy
Solution Approach 1:
The invention extracts the harmful rolling friction interface by removing the rollers from the supporters. Instead of using rollers to support the protective frame connected body, the patent uses direct contactless support through magnetic fields, eliminating the source of rolling friction that degrades movement accuracy while maintaining support stability.
Solution Approach 2:
The invention replaces the mechanical roller support system with a magnetic field-based support system. By using magnetic fields to support the protective frame connected body without physical contact, the system eliminates rolling friction while maintaining the ability to support the structure at different positions and prevent sagging.
2Manufacturing precision
If the supporter structure is simplified without rollers, then friction is reduced and movement accuracy improves, but the ability to support large cable guides may be compromised
Solution Approach 1:
The invention replaces mechanical contact-based support with magnetic field-based support. The magnetic field provides sufficient support capacity for large cable guides while eliminating the need for rollers, thus maintaining both support strength and movement accuracy simultaneously.
Solution Approach 2:
The invention changes the fundamental parameter of support interaction from mechanical contact to magnetic field interaction. This parameter change enables the support system to handle large cable guides without the friction inherent in mechanical roller systems, achieving both high support capacity and high movement accuracy.

AI summary
A support apparatus includes: a protective frame connected body to hold a plurality of protection targets flexibly, each protection target being a flexible cable or pipe having one end connected to a fixed-side member and the other end connected to a movable-side member that moves relative to the fixed-side member, the protective frame connected body having a bending portion bent in a middle, an upper side and a lower side of the protective frame connected body overlapped vertically; a lower supporter to support the lower side of the protective frame connected body; and a plurality of upper supporters, each of the plurality of upper supporters supporting the upper side of the protective frame connected body at a predetermined position of the protective frame connected body and being moved by movement of the movable-side member to pass the bending portion without being in contact with the bending portion.
