Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional PoE lights are used, then installation is simple, but they cannot provide sufficient wattage for high-quality video lighting applications
Solution Approach 1:
The patent combines power delivery and data communication into a single Ethernet cable infrastructure. The PoE injection unit delivers both electrical power and control signals through the same cable that would traditionally only carry data, eliminating the need for separate power wiring while supporting high-wattage lights of 30 watts or more.
Solution Approach 2:
The Ethernet cable infrastructure is made multi-functional by enabling it to simultaneously provide power delivery, data communication, and lighting control. The PoE injection unit and receiving unit work together to make the standard Ethernet cable capable of supporting high-wattage lighting applications while maintaining compatibility with existing network infrastructure.
2Power
If separate power wiring is installed for high-wattage lights, then sufficient power can be delivered, but installation becomes extensive and costly
Solution Approach 1:
The patent merges power delivery and data communication into a single Ethernet cable infrastructure. The PoE injection unit delivers both electrical power and control signals through the same cable that would traditionally only carry data, eliminating the need for separate power wiring while supporting high-wattage lights of 30 watts or more.
Solution Approach 2:
The system utilizes the existing Ethernet cable infrastructure already present in the building for its dual purpose of data communication and power delivery. By making the existing infrastructure serve the additional function of power delivery, the patent eliminates the need for new power wiring installations, reducing both cost and complexity.
3Power
If conventional lighting systems are used, then high wattage can be achieved, but independent control and mounting options are limited
Solution Approach 1:
The patent segments the lighting control into individually addressable PoE lights, each with its own receiving unit that can be independently controlled through the network. This allows each light fixture to be mounted separately and controlled independently, providing versatility in both placement and operation while maintaining high-wattage capability.
Solution Approach 2:
The network infrastructure acts as an intermediary between the control system and the PoE lights. The Ethernet cable and PoE injection/receiving units enable independent control of each light fixture through digital communication protocols, allowing flexible mounting options and individual adjustment of lighting parameters without physical reconfiguration.
