Sliding Structure for Large-Screen Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding structures are inadequate for large-sized electronic devices, such as large-screen mobile phones, due to their design being suited for smaller, thicker devices with low precision requirements, which limits their application in larger formats.
Innovation Solution
A sliding structure comprising an upper and lower substrate with strategically positioned slide grooves and rails, along with optional springs and auxiliary slide rails, allowing for secure and precise sliding motion without interference from fastening components, and enabling a smaller gap between sliders for improved functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional slide rail structure is used for small devices, then the device can be opened or closed, but the structure becomes too thick and cannot be applied to large-sized devices with long slide rail strokes
Solution Approach 1:
The slide rail structure is divided into multiple segments: a first slide rail on the first substrate, a second slide rail on the second substrate, and a third slide rail connecting them. This segmentation allows the slide rail to achieve a longer effective stroke for large devices while keeping each individual segment compact, thus reducing overall device thickness.
Solution Approach 2:
The patent introduces a vertical stacking dimension by placing slide rails on different substrates (first substrate and second substrate) rather than extending a single long slide rail in one dimension. The third slide rail connects these stacked components, effectively converting a one-dimensional length problem into a three-dimensional spatial arrangement, enabling long stroke without increased thickness.
2Length of moving object
If a long slide rail stroke is required for large devices, then the sliding range increases, but the precision requirement increases making conventional structures inadequate
Solution Approach 1:
The slide rail is segmented into multiple sections (first, second, and third slide rails) that can be manufactured separately with standard precision requirements, then assembled together. This avoids the need to manufacture one extremely long slide rail with high precision, which would be difficult and costly.
Solution Approach 2:
The third slide rail acts as an intermediary component connecting the first and second slide rails on different substrates. This intermediary element enables the transmission of sliding motion across substrates while maintaining precision through controlled connection points, effectively bridging the gap between separate precision components.
3Stability of the object's composition
If fastening components are used to secure substrates, then structural stability is achieved, but the fastening components may interfere with the sliding motion
Solution Approach 1:
The patent applies fastening components only at specific locations that do not interfere with the sliding path. The slide rails are designed to pass through or around fastening points, ensuring that structural stability is maintained at connection points while sliding smoothness is preserved in the motion areas.
Solution Approach 2:
The slide rail structure serves as an intermediary mechanism that mediates between the need for structural stability (provided by fastening components) and the need for smooth sliding motion. The slide rail is designed to navigate around fastening points, allowing both requirements to coexist without interference.
