Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless transmitter is added to enable DLNA protocol compliance for audio data transmission, then wireless communication capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the wireless transmitter functionality directly into the LED lighting device by integrating a wireless communication module that supports DLNA protocols. This integration eliminates the need for separate external transmitters, thereby reducing overall system complexity while maintaining wireless communication capability for audio data transmission and lighting control.
Solution Approach 2:
The LED lighting device is designed with multi-functionality by incorporating a universal wireless communication module that can handle both lighting control and audio data transmission through DLNA protocol. This single module serves multiple purposes, replacing what would traditionally require separate specialized components, thus improving adaptability without proportionally increasing complexity.
2Adaptability or versatility
If a wireless transmitter is added to enable DLNA protocol compliance, then wireless communication capability is improved, but device cost increases
Solution Approach 1:
By combining the wireless communication module with the existing LED lighting device structure, the patent achieves cost efficiency through shared components and integrated manufacturing processes. The unified design allows for economies of scale and reduces assembly costs compared to integrating separate transmitter units.
Solution Approach 2:
The multi-functional wireless communication module serves both lighting control and audio transmission functions, reducing the need for multiple specialized components. This universality lowers the overall bill of materials cost and simplifies the manufacturing process while maintaining full DLNA protocol compliance.
3Adaptability or versatility
If a wireless transmitter is added for audio data transmission, then wireless communication capability is improved, but ease of integration with mobile terminals deteriorates
