Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless or wired communication methods are used to control illumination devices, then communication functionality is achieved, but design complexity and cost increase due to complex power adaptor connections
Solution Approach 1:
The patent combines power supply and communication signal transmission into a single Ethernet cable using Power over Ethernet (POE) technology. The power supply module integrates both power reception from Ethernet and power generation for internal modules, eliminating the need for separate power adaptors and reducing design complexity while maintaining communication functionality.
Solution Approach 2:
The Ethernet cable is made multi-functional by enabling it to simultaneously transmit both electrical power and communication signals to the illumination control device. The power supply module receives power over Ethernet and generates multiple supply powers for different internal modules, allowing a single cable to serve multiple purposes and reduce overall system complexity.
2Power
If external power adaptors are used to power illumination control devices, then adequate power supply is ensured, but device complexity and cost increase
Solution Approach 1:
The patent extracts the power adaptor function from the external domain and integrates it into the illumination control device itself. The power supply module internally converts Power over Ethernet into multiple supply powers needed by different modules, removing the need for external power adaptors and reducing device complexity while ensuring adequate power supply.
Solution Approach 2:
The illumination control device becomes self-sufficient by integrating a power supply module that can autonomously convert Power over Ethernet into the multiple supply powers required by its internal modules. The device serves its own power needs without requiring external power adaptors, reducing complexity while maintaining adequate power supply.
