Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication technologies are used, then data transfer stability is improved, but bandwidth limitation and cost increase occur
Solution Approach 1:
The patent replaces wired mechanical connection systems with optical communication systems. Specifically, it uses light-emitting diodes (LEDs) to transmit data wirelessly through visible light, eliminating the need for physical cables while achieving both high bandwidth and stable data transfer. This substitution of mechanical wiring with optical fields resolves the contradiction between stability and bandwidth.
2Ease of operation
If wireless communication technologies like Wi-Fi are used, then ease of operation is improved, but bandwidth limitation and security vulnerabilities occur
Solution Approach 1:
The patent replaces traditional radio-frequency wireless communication (Wi-Fi) with optical wireless communication using visible light. This substitution enables higher bandwidth capacity while maintaining wireless ease of operation, and inherently provides improved security through the line-of-sight requirement and inability to penetrate walls, thus resolving the contradiction between ease of operation and bandwidth/security.
3Productivity
If visible light communication is implemented, then bandwidth and security are improved, but device complexity increases
Solution Approach 1:
The patent makes existing LED components serve dual purposes: their traditional function for illumination and their new function for data transmission. By enabling LEDs to perform both lighting and communication tasks, the system avoids adding separate dedicated transmission components, thus reducing overall device complexity while achieving high bandwidth capability.
