Portable Computer Display Sliding Assembly Friction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable computers with rotatable displays face friction issues in their connecting mechanisms, leading to wear and inconvenience in operation, as they lack auxiliary sliding devices to reduce friction during rotation.
Innovation Solution
Incorporating a sliding assembly with an auxiliary sliding device made of materials with high surface slip properties, such as self-lubricating polyoxymethylene, between the sliding element and the sliding guide structure, to minimize direct contact and friction between the sliding element and the guide structure, allowing for smoother rotation of the display module relative to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connecting mechanisms (linkage rods or sliding blocks) are used to rotate the display screen, then the display can be rotated relative to the base, but friction between the elements causes wear and influences rotation smoothness
Solution Approach 1:
A buffer element is introduced as an intermediary component between the sliding block and the slide rail. This buffer element reduces direct friction contact between the connecting mechanism elements, thereby reducing wear and improving rotation smoothness while maintaining the rotational function of the display screen.
2Ease of operation
If auxiliary sliding devices are added to reduce friction, then the display module can move smoothly, but the device complexity increases
Solution Approach 1:
The buffer element serves as a simple intermediary component that can be integrated into the existing sliding assembly structure. It reduces friction without requiring complex additional mechanisms, thereby improving movement smoothness while minimizing increases in device complexity.
