Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges with internal stress and structural stability due to differences in screen distance between folded and unfolded states, leading to potential damage and reduced portability.
Innovation Solution
A foldable supporting apparatus comprising a mounting base, rotating shaft, telescopic assembly, and pushing assembly, which allows for adjustable distance between components to compensate for differences in screen distance, ensuring stable folding and unfolding while maintaining a large display area and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display area is increased, then the screen size is improved, but the portability deteriorates
Solution Approach 1:
The device is divided into two separate bases (first base and second base) that can be folded together, allowing the large display to be segmented into foldable sections. This enables a large screen area while maintaining portability through folding capability.
Solution Approach 2:
The device employs a dynamic folding mechanism with rotating shafts and telescopic assemblies that allow the device to transition between unfolded (large display) and folded (compact) states. This dynamic structure resolves the contradiction between large display area and portability.
2Length of moving object
If the screen is folded, then the portability is improved, but the internal stress increases causing screen damage
Solution Approach 1:
A telescopic assembly is introduced as an intermediary component between the bases and the screen assembly. This telescopic mechanism compensates for distance differences during folding, reducing internal stress on the screen by providing a buffer that absorbs dimensional changes.
Solution Approach 2:
The telescopic assembly changes its length parameter dynamically during the folding process, adjusting to compensate for the distance difference between the two ends of the screen. This parameter adjustment reduces internal stress by maintaining appropriate tension throughout the folding transition.
3Length of moving object
If the screen is folded, then the portability is improved, but the structural stability deteriorates
Solution Approach 1:
The supporting apparatus is segmented into multiple independent components (first base, second base, rotating shafts, telescopic assemblies, pushing assemblies) that work together to maintain structural stability during folding. Each segment can move independently while contributing to overall structural integrity.
Solution Approach 2:
The device uses dynamic mechanisms (rotating shafts with telescopic and pushing assemblies) that actively adjust during folding to maintain structural stability. These dynamic components ensure that the screen and bases remain properly positioned and supported throughout the folding transition.
