Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing linear and arc-shaped transmission mechanisms in cable management apparatuses suffer from limited processing accuracy, leading to slider deformation and reduced smoothness of sliding, which affects the efficiency of the transmission mechanism.

Innovation Solution

A transmission mechanism is designed with a guiding rail and a slider equipped with a rolling part that rolls on the guiding rail, limiting the slider's movement in specific directions perpendicular to the length direction of the guiding rail, thereby preventing deformation and ensuring smooth sliding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a guiding rail and slider are used to achieve relative movements in existing transmission mechanisms, then the mechanism can provide linear or arc-shaped motion, but the slider is easy to deform and get stuck on the guiding rail after long-term use due to limited processing accuracy, affecting the smoothness of sliding

Engineering Contradiction:

Improvesmoothness of slidingVSAvoidstability of slider movement

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the traditional sliding contact between slider and guiding rail with a rolling contact mechanism. The slider is equipped with rolling elements (such as rollers or balls) that roll along the guiding rail, converting sliding friction into rolling friction. This substitution significantly reduces friction and prevents the slider from deforming and getting stuck, thereby maintaining smooth operation and reliability over long-term use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If limited processing accuracy is used in manufacturing the transmission mechanism, then the manufacturing cost is reduced, but the slider deforms after long-term use, reducing the working efficiency of the transmission mechanism

Engineering Contradiction:

Improvemanufacturing costVSAvoidworking efficiency of transmission mechanism

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent introduces a rolling mechanism with rolling elements that compensate for manufacturing inaccuracies. The rolling contact allows for smoother movement even when the guiding rail or slider has minor dimensional variations, reducing the impact of limited processing accuracy on working efficiency while maintaining cost-effective manufacturing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the contact mode from sliding to rolling, fundamentally altering the friction characteristics and movement parameters of the transmission mechanism. This parameter change enables the system to maintain high working efficiency despite moderate manufacturing precision by reducing wear and deformation over time.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If the slider is allowed to move freely on the guiding rail, then the mechanism is simpler in structure, but the slider is prone to deformation and sticking, affecting the smoothness of sliding

Engineering Contradiction:

Improvestructure of transmission mechanismVSAvoidsmoothness of sliding

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent incorporates rolling elements into the slider structure, converting the simple sliding interface into a rolling contact system. While this adds some structural complexity, it dramatically improves the smoothness of sliding by reducing friction and preventing sticking, ensuring reliable operation throughout the mechanism's service life.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
