Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of substrates are used for different resolutions, then the display apparatus can be adapted to various resolutions, but the manufacturing complexity and device variety increase
Solution Approach 1:
The patent implements a universal substrate design where a single substrate type can be configured to support multiple resolutions through adjustable dimming block configurations. The substrate includes connection portions that can be selectively connected or disconnected to reconfigure the LED arrangements into different dimming blocks, allowing one substrate to serve multiple resolution requirements without requiring separate substrate types for each resolution.
Solution Approach 2:
The patent introduces dynamic reconfigurability to the substrate through connection portions that can be selectively connected or disconnected. This dynamic adjustment capability allows the same substrate to adapt its LED arrangement configuration based on the required resolution, transforming a static substrate design into a dynamic one that can respond to different operational requirements.
2Manufacturing precision
If the number of LEDs in dimming blocks varies by resolution, then the display quality can be optimized, but the wiring arrangement and driving devices must be redesigned for each substrate type
Solution Approach 1:
The patent designs the substrate with universal wiring patterns that can serve multiple dimming block configurations. The connection portions are strategically placed to allow the same wiring arrangement to support different numbers of LEDs in dimming blocks depending on which connection portions are activated, eliminating the need to redesign wiring for each resolution.
Solution Approach 2:
The patent segments the substrate into modular connection portions that can be independently controlled. Each connection portion represents a discrete segment that can be connected or disconnected to adjust the dimming block configuration, allowing flexible reconfiguration without affecting the entire wiring arrangement.
3Adaptability or versatility
If various types of substrates are required for different resolutions, then the display apparatus can support multiple resolutions, but the manufacturing process becomes more complex and inefficient
Solution Approach 1:
The patent creates a universal substrate platform that can be manufactured once and used for multiple resolutions. The single substrate type includes all necessary connection portions and wiring patterns to support different dimming block configurations, eliminating the need to manufacture and manage multiple substrate types for different resolutions, thereby significantly improving manufacturing efficiency.
