Triple-Track Interlinking With Elastic Roller for Smooth Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional track-based synchronous interlinking mechanisms suffer from vibrations and unsmooth sliding due to asynchronous interactions between tracks, high costs of toothed wheels and ruler-like sawteeth, and structural instability caused by down force, leading to suboptimal performance and economic inefficiency.
Innovation Solution
A track-based synchronous interlinking device featuring a lower track with a knurl pattern, a central track, and an external track with a knurl pattern, utilizing a flexible roller bracket and roller to facilitate smooth and accurate sliding, with the roller contacting the knurl patterns to ensure synchronous operation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a toothed wheel and ruler-like sawteeth are used for synchronous interlinking, then synchronous operation is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates the complex toothed wheel and sawteeth components from the synchronous interlinking mechanism. Instead, it uses a simplified structure where the external track directly engages with the lower track through complementary profiled surfaces, achieving synchronous operation without the need for intermediate gear-like components.
Solution Approach 2:
The patent uses profiled surfaces on the tracks that replicate the engagement function of teeth and gears. The interlocking profiles on the external and lower tracks copy the synchronous engagement function of traditional gear mechanisms but in a simplified, integrated form that reduces complexity.
2Reliability
If a toothed wheel and ruler-like sawteeth are used for synchronous interlinking, then synchronous operation is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent removes the expensive toothed wheel and sawteeth components and replaces them with profiled track surfaces that can be manufactured more economically through standard extrusion or molding processes, significantly reducing material costs and assembly requirements.
Solution Approach 2:
The patent merges the synchronous interlinking function directly into the track structures themselves, eliminating the need for separate interlinking components. This integration reduces the total number of parts, simplifies manufacturing, and lowers overall system cost while maintaining synchronous operation.
3Strength
If rigid material is used for toothed wheel and sawteeth, then structural strength is achieved, but down force causes axle deviation and unsmooth operation
Solution Approach 1:
The patent changes the material parameter from rigid to flexible for the external track, allowing it to deform elastically under down force. This flexibility compensates for axial deviations and maintains smooth operation, while the lower track retains its structural strength through rigid construction.
4Reliability
If toothed wheel and sawteeth are installed between slide tracks, then synchronous interlinking is achieved, but the track assembly height increases
Solution Approach 1:
The patent combines the synchronous interlinking function directly into the track profiles themselves, eliminating the need for separate toothed wheels and sawteeth that would add height. The interlocking profiled surfaces are integrated into the track cross-section, minimizing the vertical space required.

Implementation Method 1
a roller which is a flexible or elastic component pivoted to the roller bracket and allows its both sides to contact the lower track's knurl pattern and the external track's knurl pattern
Implementation Method 2

AI summary
A track-based synchronous interlinking device having a lower track with a knurl pattern; a central track completing slides relative to the lower track; and an external track completing slides relative to the central track and having a knurl pattern. A synchronous interlinking device includes a roller bracket positioned at the central track and a roller featuring flexibility and elasticity, pivoted to the roller bracket, and allowing both sides to resist the lower track's knurl pattern and the external track's knurl pattern. The synchronous interlinking device completes smooth and accurate relative slides based on a synchronous triple-track interlinking operation among the lower track, the central track and the external track.
