Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LED display is cut into desired shapes, then the adaptability and versatility of the display is improved, but the electrical connectivity is disrupted causing non-display areas
Solution Approach 1:
The display is divided into multiple LED modules, each with independent control capabilities. The daisy-chain wiring connects these modules in series, allowing each module to receive control signals sequentially. This segmentation enables the display to be cut into desired shapes while maintaining functional integrity, as each module can operate independently or be selectively controlled.
Solution Approach 2:
The patent implements dynamic control of LED modules through daisy-chain wiring, where control signals are sequentially transmitted through each module. This dynamic signal transmission allows the system to adapt to different cutting configurations, enabling flexible shape changes while maintaining reliable electrical connectivity through the serial connection architecture.
2Ease of operation
If the LED display is made flexible and transparent, then the ease of operation and installation is improved, but the manufacturing precision and structural stability deteriorate
Solution Approach 1:
The patent employs flexible and transparent substrates to mount the LED modules, enabling the display to be bent, stretched, or shaped without compromising functionality. The daisy-chain wiring architecture is specifically designed to work with these flexible substrates, maintaining electrical connectivity even when the physical structure is deformed or cut into non-traditional shapes.
Solution Approach 2:
By dividing the display into discrete LED modules connected through daisy-chain wiring, the patent achieves both flexibility and structural stability. Each module can be independently positioned and connected, allowing for precise assembly while maintaining overall structural integrity even when using flexible substrates.
