Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices suffer from a poor viewing experience due to excessive distance between dual display screens when opened or closed, disrupting visual continuity.
Innovation Solution
A foldable electronic device design featuring a dual-axis hinge module with linkage mechanisms that allow the first and second objects to slide relative to each other, reducing the distance between them when rotated, thereby eliminating gaps and enhancing viewing continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large distance is provided between the two display screens and the hinge module, then the display screens do not interfere with each other when the two bodies are opened or closed, but the distance between the two display screens becomes excessively large when the two display screens are parallel, hindering visual continuity
Solution Approach 1:
The patent applies the dynamics principle by making the first and second objects movable relative to the first and second bodies through sliding mechanisms. When the two bodies are parallel, the first object slides on the first body and the second object slides on the second body, allowing them to move closer together and eliminate the excessive distance gap. This dynamic adjustment resolves the contradiction by adapting the distance between display screens based on the relative position of the two bodies.
Solution Approach 2:
The patent segments the rigid structure into movable components by introducing sliding mechanisms that allow the first and second objects to independently adjust their positions on各自的 bodies. This segmentation enables the system to dynamically reconfigure the distance between display screens, resolving the contradiction between maintaining non-interference and achieving visual continuity.
2Ease of operation
If the two display screens are positioned close to each other when parallel, then visual continuity is improved, but the display screens may interfere with each other during opening or closing operations
Solution Approach 1:
The dynamic sliding mechanisms allow the first and second objects to automatically adjust their positions based on the relative angle between the two bodies. When the bodies are parallel, the objects slide to reduce distance and improve visual continuity. When the bodies are opened or closed, the objects slide to increase distance and prevent interference, thus resolving the contradiction between visual continuity and non-interference.
Solution Approach 2:
The patent changes the positional parameters of the first and second objects dynamically. By allowing the objects to slide along the bodies, the distance parameter between display screens is adjusted according to the operational state, enabling close positioning for visual continuity while maintaining sufficient separation to prevent interference during movement.
