Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet computers with sliding touch panels often experience friction issues due to over contact between the sliding structure and the track's side wall, leading to jammed situations and reduced operational convenience.
Innovation Solution
A fixing mechanism featuring a track portion with positioning structures and a sliding portion with engaging structures, including spherical members and resilient members, that engage only at specific positions to reduce friction and stabilize the display module's sliding motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sliding structure contacts the side wall of the track continuously, then the display module is constrained within the track, but friction increases causing jamming
Solution Approach 1:
The continuous contact between sliding structure and track side wall is segmented into discrete engagement points. Positioning structures are distributed at specific intervals along the track, and engaging structures on the sliding portion only contact these positioning structures at designated positions rather than continuously along the entire track length, thereby reducing overall friction while maintaining constraint stability.
Solution Approach 2:
Positioning structures and engaging structures serve as intermediary elements between the sliding portion and the track. These intermediaries enable selective engagement at specific positions, allowing the sliding structure to be constrained when needed while minimizing contact friction during movement, thus resolving the contradiction between stability and ease of operation.
2Ease of operation
If the sliding structure has minimal contact with the track, then friction is reduced, but the display module becomes unstable
Solution Approach 1:
Positioning structures are pre-positioned at specific locations along the track where engagement is required for stability. The engaging structures on the sliding portion are designed to automatically engage with these pre-positioned positioning structures when the sliding portion reaches these predetermined positions, ensuring stability is provided in advance at critical points without requiring continuous contact.
Solution Approach 2:
The constraint system transitions from a static continuous contact model to a dynamic selective engagement model. The engaging structures can move freely between positioning structures during sliding, then dynamically engage with the positioning structures when reaching specific positions to provide stability, and disengage to allow smooth movement, creating a dynamic balance between stability and ease of operation.

Function Achieved in This Case
This solution allows for smooth sliding and stable fixation of the display module, enhancing operational convenience and reducing jamming incidents by minimizing friction during the sliding process.
Implementation Method 1
The resilient member abuts against the spherical member for providing the spherical member with a resilient force, so as to drive the spherical member to engage with the recess structure when the sliding portion slides to the engaging position relative to the track portion
