Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable and guide devices experience wear loss and impact noise due to contact between adjacent side plate units when guiding control signal transmission cables, particularly during linear position holding and flexional position restriction.
Innovation Solution
A cable protection and guide device with pairs of spaced side plate units connected from a mounting fixed end to a movable end, featuring detachable connecting plates and flexible coupling portions, with elastically deformable stop members and larger abutment surfaces to disperse contact impact forces and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional cable chain with rigid side plates is used, then structural strength is maintained, but contact impact noise and wear occur between adjacent side plates during flexion
Solution Approach 1:
The side plate is divided into multiple independent units connected by flexible coupling portions, allowing each unit to move independently during flexion, thereby preventing direct contact between adjacent rigid side plates and eliminating impact noise while maintaining overall structural strength
Solution Approach 2:
The patent introduces flexible coupling portions made of elastic materials that connect adjacent side plate units, enabling the structure to flex without rigid contact, thus reducing impact noise while preserving the necessary structural integrity through the elastic properties of the coupling material
2Reliability
If rigid side plates are used to maintain structural integrity, then manufacturing simplicity is achieved, but wear loss occurs due to contact between adjacent side plates
Solution Approach 1:
By segmenting the side plate into multiple units connected by flexible couplings, the patent eliminates direct rigid contact between adjacent units during flexion, thereby preventing wear loss while maintaining the durability needed for reliable operation in clean environments
Solution Approach 2:
The patent changes the physical state of the connection between side plate units from rigid to flexible through the use of elastic coupling portions, which allows relative movement without contact wear, thus improving reliability by eliminating wear loss
3Force
If larger abutment surfaces are provided on outer circumferential side, then impact force distribution is improved, but device complexity increases
Solution Approach 1:
The patent applies different abutment surface sizes to different locations: larger abutment surfaces are provided on the outer circumferential side where impact forces are greater, while smaller surfaces are used on the inner circumferential side, optimizing force distribution without unnecessarily increasing overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively suppresses contact impact noise and enhances fatigue resistance by distributing contact forces and reducing wear, allowing for reliable operation in clean environments.
Implementation Method 1
a flexible coupling portion integrally intervened between the side plate front portion and the side plate rear portion
Implementation Method 2
The inner circumferential side flexional position restricting mechanism and the inner circumferential side linear position holding mechanism are each composed of an at least elastically deformable stop member

AI summary
A cable protection and guide device in which contact impact noise between adjacent side plates is dispersed. The noise is liable to occur at the time of linear position holding and at the time of flexional position restriction when cables accommodated therein are transmitted or moved from a mounting fixed end toward a mounting movable end. A number of pairs of right and left side plate units (110) are connected from a mounting fixed end to a mounting movable end and side plate unit comprises a side plate front portion (111) which is connected to a preceding side plate unit (110), a side plate rear portion (112) which is connected to a subsequent side plate unit (110), and a flexible coupling portion (113) integrally intervened between the side plate front portion (111) and the side plate rear portion (112). The side plate unit 110 includes an outer circumferential side linear position holding mechanism Xo and an outer circumferential side flexional position restricting mechanism Yo at a side plate front portion (111) on a flexional outer circumferential side rather than the coupling portion (113). The side plate also includes an inner circumferential side flexional position restricting mechanism Yi and an inner circumferential side linear position holding mechanism Xi at a side plate rear portion (112) on a flexional inner circumferential side rather than the coupling portion (113).
