Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face challenges in achieving a larger display size while maintaining mechanical stability and portability, particularly in foldable or rollable designs, due to limitations in their display structures.
Innovation Solution
The implementation of a hinge module that includes a rotating structure, interlocking mechanism, and fixing structure to stabilize the folding and unfolding of housings in electronic devices, allowing for a stable operation and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a foldable display structure is implemented to achieve a larger display size, then the display area is increased, but the mechanical stability deteriorates
Solution Approach 1:
The housing is divided into multiple segments (first housing and second housing) that can fold relative to each other, allowing the display to achieve a larger area when unfolded while maintaining a compact form when folded. The segmentation enables the display structure to adapt between expanded and contracted states without compromising overall structural integrity.
Solution Approach 2:
A hinge module is introduced as an intermediary mechanism between the first and second housings. This hinge module includes rotating members, guide members, and locking mechanisms that mediate the folding and unfolding motions, ensuring stable operation and maintaining mechanical stability during transitions between different display configurations.
2Area of moving object
If the display size is increased to satisfy multimedia service requirements, then the user experience is improved, but the portability deteriorates
Solution Approach 1:
The display structure is made dynamic through the foldable hinge mechanism, allowing it to change its effective length and area based on usage requirements. When unfolded, the display provides a large area for multimedia consumption; when folded, it reduces to a compact size for portable carrying, thus resolving the contradiction between display size and portability.
3Adaptability or versatility
If a foldable structure is implemented to enable larger display, then the display versatility is improved, but the device complexity increases
Solution Approach 1:
The hinge module components are nested within each other in a compact arrangement. The rotating members, guide members, and locking mechanisms are integrated in a space-efficient manner, reducing the overall complexity of the folding mechanism while maintaining the versatility of the display structure.
