Solution Overview
Problem
Existing foldable electronic devices, such as those of the Watt six-bar type, face limitations in smoothly transitioning between unfolded and folded states, particularly in managing the flexible screen's bending and accommodation, and often require complex rotating mechanisms that can be cumbersome and inefficient.
Innovation Solution
A foldable electronic device employing Stephenson II six-bar mechanisms with sliding components, including inner and outer arc-shaped sliders, pivot joints, and a torque module with elastic washers, allows for synchronized and efficient transformation between unfolded and folded states by utilizing sliding instead of rotating motions, ensuring smooth operation and flexible screen accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Watt six-bar type rotating mechanisms are used, then the foldable electronic device can achieve folding function, but the transition between unfolded and folded states is not smooth and the structure becomes complex
Solution Approach 1:
The patent replaces the traditional rotating mechanism with a sliding mechanism. Specifically, the arc-shaped slider moves along the arc-shaped slideway, converting rotational motion into linear sliding motion. This substitution simplifies the mechanical structure while achieving smooth transition between unfolded and folded states, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent divides the folding mechanism into multiple independent sliding components: inner arc-shaped sliders, outer arc-shaped sliders, and corresponding slideways. Each component performs a specific sliding action, and their coordinated movement achieves the overall folding function. This segmentation reduces the complexity of any single component while maintaining smooth transition capability.
2Productivity
If complex rotating mechanisms are used to achieve folding, then the folding function is realized, but the operation becomes cumbersome and inefficient
Solution Approach 1:
By replacing rotating mechanisms with sliding mechanisms, the patent enables more efficient state transformation. The sliding action of the arc-shaped slider along the arc-shaped slideway requires less force and moves more smoothly than rotational mechanisms, directly improving productivity while reducing operational difficulty.
Solution Approach 2:
The patent employs dynamic sliding connections that allow continuous movement between states. The sliding interface between the arc-shaped slider and slideway maintains continuous contact, enabling smooth dynamic transition without the discrete steps or friction peaks associated with rotating mechanisms, thereby improving efficiency and ease of operation.
3Reliability
If traditional folding mechanisms are used, then the device can fold, but the flexible screen's bending and accommodation is not well managed
Solution Approach 1:
The sliding mechanism provides more predictable and stable motion control compared to rotating mechanisms. The arc-shaped slider moving along the fixed arc-shaped slideway ensures consistent geometric relationships throughout the folding process, providing reliable support for the flexible screen while maintaining simpler structure.
Solution Approach 2:
The patent employs arc-shaped sliders and arc-shaped slideways that utilize curved geometry. This curvature design naturally guides the motion of the folding components, providing inherent geometric constraints that stabilize the flexible screen during bending and folding, improving reliability without adding complexity.
