Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If both batteries are selected simultaneously for power supply, then the power supply capacity is increased, but power loss increases and efficiency decreases
Solution Approach 1:
The patent implements dynamic power supply mode switching between single-battery mode and dual-battery combination mode based on real-time detection of battery voltages and operational requirements. The control circuit dynamically selects the optimal power supply configuration to balance power capacity and efficiency, avoiding continuous dual-battery operation that causes excessive power loss.
Solution Approach 2:
The system changes operational parameters by switching between different power supply modes (single battery vs. combination mode) based on voltage thresholds and load requirements. This parameter change allows the system to optimize the balance between power supply capacity and power loss under different operating conditions.
2Reliability
If combination mode is used continuously, then power supply stability is improved, but power loss increases
Solution Approach 1:
The control circuit dynamically switches between combination mode and single-battery mode based on real-time voltage detection and operational needs. This dynamic approach maintains power supply stability when combination mode is beneficial while avoiding continuous operation that causes excessive power loss.
Solution Approach 2:
The system uses its own voltage detection capability to automatically determine when to switch between power supply modes, making the decision-making process self-contained without external intervention. The control circuit monitors battery voltages and autonomously selects the optimal power supply configuration.
3Loss of energy
If single battery mode is used, then power loss is reduced, but power supply capacity is insufficient for high-load operations
Solution Approach 1:
The system dynamically transitions between single-battery mode and combination mode based on detected voltage levels and operational requirements. When high power capacity is needed, the system switches to combination mode; when lower power is sufficient, it operates in single-battery mode to minimize power loss.
Solution Approach 2:
The operational parameters are changed by switching power supply modes based on voltage thresholds and load conditions. This allows the system to adapt between efficiency-oriented single-battery operation and capacity-oriented combination operation.
4Loss of energy
If voltage threshold switching is implemented, then power efficiency is optimized, but control circuit complexity increases
Solution Approach 1:
The control circuit is pre-configured with voltage threshold values that determine when to switch between power supply modes. This preliminary setup allows the system to automatically optimize power efficiency through simple threshold comparisons rather than complex real-time calculations, minimizing control circuit complexity while maintaining optimization capability.

AI summary
An imaging apparatus which can be mounted with a first battery and a second battery includes: a load circuit configured to operate the imaging apparatus; and a control circuit configured to control power supply to the load circuit based on a first battery voltage in the first battery and a second battery voltage in the second battery. In a high-load mode, the control circuit selects any one of the first battery, the second battery, and a combination of the first and second batteries in accordance with the first and second battery voltages, to supply power to the load circuit. In a low-load mode, the control circuit selects either one of the first battery and the second battery in accordance with the first and second battery voltages without selecting the combination of the first and second batteries, to supply power to the load circuit.
