Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring methods are used to control building systems, then reliable control can be achieved, but installation costs increase and architectural features may be damaged
Solution Approach 1:
The patent replaces traditional mechanical wiring systems with optical communication systems using LEDs and photodetectors. Data is transmitted through light signals between transceivers installed in light fixtures, eliminating the need for complex electrical wiring while maintaining reliable control of building systems.
Solution Approach 2:
The patent integrates multiple functions into existing light fixtures. The same fixtures that provide illumination also serve as transceivers for data communication and control signals, eliminating the need for separate control wiring infrastructure.
2Ease of manufacture
If wireless communication systems like Wi-Fi are used, then ease of installation is improved, but reliability and control precision deteriorate
Solution Approach 1:
The patent uses light as an intermediary medium for data transmission between fixtures. Optical transceivers convert electrical control signals into light signals that travel through the fixture housing, providing a reliable physical medium for communication that is less susceptible to interference than wireless radio frequency systems.
3Ease of manufacture
If existing light fixtures are transformed into smart fixtures, then cost-effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines lighting elements and optical transceivers into integrated modules that can be installed as complete units in existing fixtures. This modular approach reduces the complexity of installation by pre-assembling the communication and lighting components together.
Solution Approach 2:
The patent divides the control system into independent transceiver modules that can be individually installed in each fixture. Each module contains its own photodetector, LED, and control circuitry, allowing for simplified installation and maintenance without requiring system-wide wiring changes.
