Sliding Track Assembly Torsional Spring Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding track assemblies using single or dual spring members suffer from vibration and spring breakage due to uneven alignment and shear forces when the sliding cover is moved, leading to instability and potential deformation.
Innovation Solution
A sliding track assembly utilizing two torsional springs with aligned locating holes on both the sliding and track members, along with self-lubricating injection-molded polyoxymethylen copolymer track members, ensures balanced movement and reduced vibration by compressing and releasing energy to facilitate smooth sliding without excessive effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two spring members are used to maintain balance, then the sliding cover stability is improved, but the spring members are prone to breakage or deformation due to misalignment and shearing forces
Solution Approach 1:
The patent positions the two locating holes of the bottom plate at the same elevation and arranged symmetrically relative to the sliding rails, ensuring the fixed ends of the two spring members are aligned in line when the top cover is moved to the dead point, eliminating shearing forces and preventing spring breakage or deformation
2Device complexity
If the locating holes are arranged at different elevations for structural design, then the device complexity is reduced, but vibration occurs due to misalignment of spring ends
Solution Approach 1:
The patent positions the two locating holes of the bottom plate at the same elevation and arranged symmetrically relative to the sliding rails, ensuring the fixed ends of the two spring members are aligned in line when the top cover is moved to the dead point, eliminating shearing forces and preventing spring breakage or deformation
Applied Scientific Principles
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 solution provides stable, vibration-free sliding motion and reduces the likelihood of spring breakage by aligning torsional spring ends and using self-lubricating materials, enhancing the usability and durability of the sliding track assembly.
Implementation Method 1
two torsional springs arranged in the same direction on the track member, each having a first end respectively fastened to the locating holes of the sliding member and a second end respectively fastened to the at least one locating hole of the track member
Implementation Method 2
the track member is injection-molded from a copolymer. Preferably, the copolymer is a self-lubricating plastic material, for example, polyoxymethylen

AI summary
A track assembly includes a track member, which has two parallel sliding grooves arranged in parallel at two sides and two locating holes spaced between the sliding grooves, a sliding member, which has two sliding rails respectively coupled to the sliding grooves of the track member and two locating holes spaced between the sliding rails, and two torsional springs arranged in the same direction on said track member and respectively connected between the locating holes of the track member and the locating holes of the sliding member such that the torsional springs automatically pushes the sliding rail to the open or close position when the user pushes the sliding rail to the midway toward the open or close position.
