Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices either have a limited viewing angle, making them unsuitable for multiple viewers, or struggle to switch between curved and flat display modes effectively.
Innovation Solution
A display device with a spliced back plate composed of central-axis, intermediate, and border sub-plates, connected via a support and driven by a power module and transmission module, allowing the display screen to convert between flat and curved states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a curved display device is used, then the viewing experience for a few persons is improved, but the viewing angle and suitability for multiple viewers deteriorates
Solution Approach 1:
The back plate is designed as a movable structure that can dynamically change between curved and flat states. The curvature adjusting mechanism allows the back plate to transition from a curved configuration (providing immersive viewing for few persons) to a flat configuration (providing wide viewing angle for multiple persons), making the display adaptable to different viewing scenarios.
2Adaptability or versatility
If a flat display device is used, then the viewing angle for multiple persons is improved, but the immersive viewing experience for a few persons deteriorates
Solution Approach 1:
The back plate can dynamically switch between flat and curved states. When flattened, it provides a wide viewing angle suitable for multiple persons; when curved, it creates an immersive viewing experience for a few persons, thus resolving the contradiction between viewing angle and viewing experience quality.
3Device complexity
If the back plate is made as a single integrated piece, then the structural simplicity is improved, but the ability to convert between curved and flat states deteriorates
Solution Approach 1:
The back plate is divided into multiple sub-plates that can move relative to each other. This segmentation allows the back plate to change its overall shape from flat to curved by adjusting the relative positions of the sub-plates, while still maintaining a relatively simple overall structure.
Solution Approach 2:
The back plate incorporates a curvature adjusting mechanism that enables dynamic transformation between flat and curved states. The movable sub-plates can be positioned differently to achieve the desired curvature, providing versatility without excessive structural complexity.
4Adaptability or versatility
If the back plate is divided into multiple movable sub-plates, then the curved-flat conversion capability is improved, but the structural complexity increases
Solution Approach 1:
The back plate is segmented into multiple sub-plates connected by movable joints, enabling curvature adjustment while keeping each individual component relatively simple. The modular design allows for curved-flat conversion without requiring an overly complex overall structure.
Solution Approach 2:
The back plate uses a series of movable sub-plates that can be arranged to form a curved surface when needed. The curvature is achieved through the geometric arrangement and relative movement of planar sub-plates, avoiding the need for complex curved components while still achieving the desired curved display effect.
