Curved Surface Substrate Support via Adjustable Suction Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting devices are inadequate for securely fixing curved surface substrates due to uneven spacing between the display screen and viewer's eyeballs, leading to vision fatigue and suboptimal display quality, especially as curved surface display apparatuses increase in size and market share.
Innovation Solution
A supporting suction assembly with adjustable height and rotatable suction cups made of flexible materials, arranged in an array to form a customizable supporting face that can conform to irregular shapes, utilizing a vacuum system for secure adhesion and adjustable extraction paths to accommodate varying curvatures and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional flat panel supporting devices are used, then flat substrates can be supported, but curved surface substrates cannot be securely fixed due to uneven spacing and poor contact
Solution Approach 1:
The supporting device employs adjustable supporting units that can independently move in vertical and horizontal directions, allowing the device to dynamically adapt to curved surface substrates. Each supporting unit includes a movable supporting plate and adjustable suction cups that can be positioned to match the contours of curved panels, resolving the contradiction between adaptability and fixing reliability.
Solution Approach 2:
The supporting device is divided into multiple independent supporting units distributed across the supporting surface. Each unit can be independently adjusted to contact specific points on the curved substrate, enabling the system to accommodate irregular shapes while maintaining secure fixation through distributed contact points.
2Area of stationary object
If the supporting device is designed for large curved surface substrates, then coverage area increases, but device complexity and adjustment difficulty increase
Solution Approach 1:
The large supporting surface is divided into multiple modular supporting units, each with identical adjustment mechanisms. This segmentation allows the system to cover large areas while maintaining manageable complexity through standardization and modularity of the adjustable components.
Solution Approach 2:
Each supporting unit is designed as a universal module capable of supporting both flat and curved surfaces through standardized adjustment mechanisms. The multi-functional design allows the same unit to adapt to various substrate shapes and sizes, reducing overall device complexity while maintaining large supporting area capability.
