Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED-based lighting systems with optical transceivers are integrated, then communication capability and smart control are enabled, but device complexity increases
Solution Approach 1:
The patent combines lighting and communication functions into a single LED-based system. The LED serves dual purposes: providing illumination and transmitting data through optical communication. This merging eliminates the need for separate communication infrastructure, reducing overall system complexity despite adding smart capabilities.
Solution Approach 2:
The LED system is designed to perform multiple functions simultaneously - lighting, data transmission, and environmental sensing. This multi-functionality allows a single device to replace multiple separate systems, enabling smart building capabilities without proportionally increasing device complexity.
2Ease of operation
If wireless optical communication is used, then installation flexibility is improved, but transmission reliability may deteriorate due to environmental factors
Solution Approach 1:
The system incorporates feedback mechanisms where the LED transceiver monitors transmission quality and adjusts its operation accordingly. This feedback loop helps maintain reliable communication by compensating for environmental variations such as ambient light conditions, ensuring stable performance despite the wireless optical nature of the transmission.
3Ease of manufacture
If standard electrical connectors are used for compatibility, then ease of installation is improved, but adaptability to different architectural settings may be limited
Solution Approach 1:
By using standard electrical connectors, the LED-based lighting system can be installed in existing fixtures across various architectural settings. The universal connector design allows the same device to adapt to different locations and configurations, achieving architectural versatility through compatibility rather than customization.
