Engineering Contradiction Analysis
1Reliability
If separate hardwired electrical lines are used for power supply to lighting device and memory device, then reliable power delivery is achieved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines separate electrical lines for power supply to the lighting device and memory device into a single shared electrical line. This merging reduces the number of electrical contacts and simplifies the coupling device while maintaining reliable power delivery to both components through a unified power transmission path.
Solution Approach 2:
The shared electrical line serves multiple functions simultaneously: it provides power supply to both the lighting device and memory device, and also functions as a communication link for data transmission. This multi-functionality reduces the overall number of electrical connections required while maintaining system reliability.
2Reliability
If multiple separate electrical lines are used for power supply and communication, then reliable data transmission is achieved, but the number of electrical contacts increases
Solution Approach 1:
The patent merges power supply and communication functions into a single shared electrical line, reducing the number of electrical contacts at the coupling device interface. The microcontroller enables bidirectional communication over this shared line through signal modulation, eliminating the need for separate dedicated communication wires.
Solution Approach 2:
The shared electrical line serves as both a power supply conduit and a communication channel. The microcontroller modulates signals on this line to enable data transmission while simultaneously providing power to the lighting device and memory device, achieving multi-functionality with a single electrical connection.
3Ease of operation
If separate electrical lines are used for lighting device and memory device power supply, then independent power control is achieved, but space requirements increase
Solution Approach 1:
The patent combines power supply lines for the lighting device and memory device into a single shared electrical line, reducing the physical space required in the coupling device. The microcontroller enables independent power control by selectively activating or deactivating power delivery to different components through electronic switching, eliminating the need for separate physical power lines.
