Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If LED-based lighting systems with multiband ultra-wideband transceivers and optical communication capabilities are integrated, then wireless control and data transmission are enabled without extensive rewiring, but device complexity increases
Solution Approach 1:
The patent combines LED lighting elements with multiband ultra-wideband transceivers and optical communication capabilities into a single integrated system. The lighting fixture serves dual purposes: providing illumination through LEDs and enabling wireless communication through integrated transceivers that operate in both radio frequency and optical domains, thereby eliminating the need for separate communication infrastructure
Solution Approach 2:
The lighting system is designed to perform multiple functions simultaneously: it provides illumination, wireless data transmission via multiband ultra-wideband radio frequency communication, and optical communication capabilities. This multi-functional design allows the same hardware infrastructure to support diverse communication needs without requiring additional dedicated systems
2Reliability
If conventional building control systems are used with separate HVAC and lighting systems, then system reliability is maintained, but loss of energy increases due to independent operation
Solution Approach 1:
The integrated lighting and control system incorporates feedback mechanisms that allow real-time monitoring and adjustment of HVAC and lighting operations. The system uses communication between lighting fixtures and control devices to optimize energy consumption based on actual environmental conditions and occupancy, thereby improving overall energy efficiency while maintaining system reliability through coordinated control
3Measurement precision
If invasive wiring is used for building control systems, then measurement precision is improved, but object-affected harmful factors increase due to structural disruption
Solution Approach 1:
The patent replaces traditional mechanical wiring infrastructure with wireless communication technologies. Multiband ultra-wideband transceivers and optical communication systems transmit data through electromagnetic and optical fields respectively, eliminating the need for physical cable installation while maintaining high data transmission accuracy. This substitution preserves building structures intact while achieving precise measurement and communication capabilities
