Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses multiple electric power sources and communication modes simultaneously, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The power supply controller dynamically adjusts the power supplying state between wireless and wired communication modes based on real-time power-source state detection. When the second electric power source is connected, the system switches to wired communication mode which consumes less energy, while maintaining communication reliability through automatic mode selection
Solution Approach 2:
The system changes operational parameters by switching between different communication modes (wireless/wired) and power source configurations based on detected power-source states. This parameter change allows the system to optimize energy consumption while maintaining communication effectiveness
2Loss of energy
If the system preferentially uses the second electric power source when connected, then stored electric power conservation is improved, but system complexity increases
Solution Approach 1:
The detector automatically detects the power-source state and provides this information to the power supply controller, which then autonomously decides the optimal power supplying state. This self-service mechanism simplifies the overall system by using automatic detection and control rather than manual intervention or complex external management systems
Solution Approach 2:
The system implements a feedback loop where the detector continuously monitors the power-source state and feeds this information back to the power supply controller. Based on this feedback, the controller adjusts the power supplying state to preferentially use the second electric power source when connected, thereby conserving stored electric power in the first power source

AI summary
A control device for a first communicator of a human-powered vehicle configured to establish one of a wireless communication and a wired communication with a second communicator comprises a power supply controller. The power supply controller is configured to control a power supplying state of at least one of a first electric power source and a second electric power source to supply electric power to the first communicator based on at least one of a power-source state of at least one of the first electric power source and the second electric power source and a communication state between the first communicator and the second communicator.
