Solution Overview

Problem

Cable tracks face challenges in preventing snagging when sections move relative to each other, which can cause damage to electrical cables or flexible tubing, and existing solutions often increase stiffness and friction, limiting mobility and requiring more energy for movement.

Innovation Solution

The use of spacers with pins that maintain a minimum distance between sections of the cable track, preventing snagging without significantly increasing friction, achieved through the design of spacers and pins that protrude from the cable track's surfaces and are coated with friction-reducing materials, allowing for smooth movement and protection of cables or tubing.

1Reliability

If mechanical means such as springs are used to prevent cable track snagging, then snagging is reduced, but stiffness and internal friction increase, limiting mobility and increasing energy requirements

Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces spacers as intermediary elements between cable track sections. These spacers maintain a minimum distance between adjacent sections, preventing direct contact and snagging without requiring mechanical springs or complex mechanisms. The spacers act as mediators that separate the cable track sections while allowing smooth relative movement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts the snag-prevention function from complex mechanical means (springs, friction elements) and implements it through simple geometric spacers with pins. By removing the need for active mechanical prevention mechanisms, the system achieves snagging prevention through passive geometric constraints that maintain separation between cable track sections.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If mechanical means such as springs are used to prevent cable track snagging, then snagging is reduced, but energy requirements for movement increase

Engineering Contradiction:
Improvesnagging preventionVSAvoidenergy for movement
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The spacers serve as passive intermediaries that prevent snagging through their geometric configuration rather than active mechanical forces. The pins on the spacers maintain separation between cable track sections without requiring energy input, eliminating the need for powered spring mechanisms or friction-based prevention systems that would consume energy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The spacer-pin structure provides self-service snag prevention through its inherent geometry. The spacers automatically maintain minimum distance between cable track sections during movement, with the pins engaging to prevent direct contact. This passive self-regulating mechanism requires no external energy input while continuously preventing snagging.

Inventive Principle:
Principle #25Self-service

3Reliability

If spacers with pins are used to maintain minimum distance between cable track sections, then snagging is prevented without significantly increasing friction, but device complexity increases

Engineering Contradiction:
Improvesnagging preventionVSAvoidcable track structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cable track is segmented into discrete sections with spacers positioned between them. Each spacer is a separate, simple component with pins that can be independently attached to the cable track sections. This segmentation allows the complex snag-prevention function to be achieved through multiple simple, standardized components rather than a single complex mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spacers and pins are strategically positioned at specific locations along the cable track where snagging is most likely to occur. Rather than uniformly complicating the entire cable track structure, the invention applies localized spacer-pin assemblies only where needed to maintain minimum distance between sections, minimizing overall structural complexity.

Inventive Principle:
Principle #3Local quality
