Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding display devices have limited folding configurations, which do not meet the evolving user experience demands as they typically have only a single or two folding axes parallel to each other.
Innovation Solution
A foldable device with a frame plate, a primary folding axis, and at least one secondary folding axis that does not intersect, dividing the frame plate into multiple sub-frame plates, connected by a folding mechanism comprising first and second folding hinges with damping mechanisms to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional folding display devices use only a single or two parallel folding axes, then the device structure remains simple, but the folding configuration variety is limited and user experience is insufficient
Solution Approach 1:
The frame plate is divided into multiple sub-frame plates (first, second, third, fourth sub-frame plates) through the intersection of primary and secondary folding axes. This segmentation enables multiple independent folding configurations while maintaining overall structural integrity, directly addressing the limitation of conventional single-axis or parallel dual-axis designs.
Solution Approach 2:
The patent introduces a secondary folding axis that intersects the primary folding axis at a predetermined angle, transitioning from a single-dimensional or parallel dual-dimensional folding system to a multi-dimensional folding configuration. This dimensional change creates diverse folding states (fully folded, partially folded, angle-folded) that enhance adaptability without proportionally increasing complexity.
2Adaptability or versatility
If multiple folding axes are introduced to improve user experience, then folding configuration variety increases, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The frame plate is divided into multiple sub-frame plates (first, second, third, fourth sub-frame plates) through the intersection of primary and secondary folding axes. This segmentation enables multiple independent folding configurations while maintaining overall structural integrity, directly addressing the limitation of conventional single-axis or parallel dual-axis designs.
Solution Approach 2:
The folding mechanism uses standardized hinge structures (first folding hinges and second folding hinges) that can be replicated across different axes and configurations. These universal hinge components perform multiple functions: enabling rotation, providing damping feedback, and maintaining structural alignment, thereby simplifying manufacturing despite the complex multi-axis configuration.
3Ease of operation
If damping mechanisms are added to folding hinges, then user feedback and control are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Damping mechanisms are integrated into the folding hinges to provide tactile feedback and resistance during the folding operation. This feedback mechanism allows users to感知 the folding state and exert appropriate force, improving ease of operation and control while preventing unintended folding or damage to the display panel.
Solution Approach 2:
The damping mechanism is merged with the folding hinge structure, combining the rotational function with the damping function in a single integrated component. This merging reduces the need for separate damping components and simplifies the overall hinge mechanism, thereby mitigating the increase in device complexity while maintaining improved user feedback.
