Cable Guide Device Offset Connecting Arm Reduces Abrasion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable protection and guide devices experience noise, abrasion, and disconnection issues when moving from a flexional position to a linear position due to the flexion outer circumferential-side connecting arm coming into contact with the support surface.
Innovation Solution
The cable protection and guide device features a flexion outer circumferential-side connecting arm that is detachably mounted and positioned closer to the cable flexion inner circumferential side, with a hinge structure to prevent disconnection, and link side plates arranged to create a gap between the arm and the support surface, reducing contact and impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexion outer circumferential-side connecting arm is coplanar with the link side plate, then the device can take a linear position in contact with the support surface, but the connecting arm comes into contact with the support surface causing noise, abrasion, and disconnection
Solution Approach 1:
The connecting arm is positioned in the depth direction (third dimension) rather than being coplanar with the link side plate. Specifically, the connecting arm is arranged closer to the cable flexion inner circumferential side, creating a spatial offset that prevents contact with the support surface while maintaining the linear position functionality
Solution Approach 2:
The link side plate structure acts as an intermediary that mediates between the connecting arm and the support surface. By positioning the connecting arm offset from the plate's outer edge, the plate itself becomes the contact element with the support surface, protecting the connecting arm from direct contact and resulting harm
2Device complexity
If the flexion outer circumferential-side connecting arm is coplanar with the link side plate, then the device structure is simple, but the connecting arm collides with the support surface causing disconnection
Solution Approach 1:
The solution maintains structural simplicity by not adding extra components, but rather by repositioning the existing connecting arm in the depth direction. This spatial rearrangement prevents collision and disconnection while keeping the overall structure straightforward and easy to manufacture
3Object-generated harmful factors
If the connecting arm is positioned closer to the cable flexion inner circumferential side, then contact with the support surface is prevented, but the cable distribution may be affected
Solution Approach 1:
The connecting arm is positioned specifically at the cable flexion inner circumferential side, which is the optimal location for preventing support surface contact. This localized positioning maintains proper cable distribution because it follows the natural cable path while providing the necessary offset from the support surface

AI summary
A cable protection and guide device is capable of preventing noise and abrasion powder generated by a flexion outer circumferential connecting arm and avoiding disconnection of the arm. The device includes: a number of link frame bodies each having link side plates each having a front side plate portion connected longitudinally to a preceding link side plate to form a cable flexion inner circumferential side; a rear side plate portion connected longitudinally to a succeeding link side plate to form a cable flexion outer circumferential side; and, a flexible linkage portion interposed between the front and rear side plate portions. The link frame body also includes a flexion outer circumferential-side connecting arm whose flexion outer circumferential-side surface is provided so as to be closer to the cable flexion inner circumferential side than a flexion outer circumferential edge of the rear side plate portion.
