Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple battery packs are connected in parallel to increase electric quantity, then the operating time of the load controller is extended, but unbalanced voltages between battery packs cause unnecessary power consumption and reduced battery life
Solution Approach 1:
The power supply system is segmented into separate battery packs, each independently connected to the load controller through switching circuitry. This allows individual battery packs to operate independently without causing voltage imbalance and energy loss from recharging, while still providing extended operating time through sequential or selective usage.
Solution Approach 2:
The system dynamically switches between different battery packs based on their charge states and operational requirements. The switching mechanism allows the load controller to adaptively select which battery pack to use, optimizing power consumption and extending overall system operating time without the energy losses associated with static parallel connections.
2Duration of action of stationary object
If multiple battery packs are connected in parallel to increase electric quantity, then the replacement frequency of batteries is reduced, but unbalanced voltages shorten the lifetime and decrease the efficiency of the battery packs
Solution Approach 1:
Battery packs are segmented into separate operational units with independent switching control. This prevents voltage imbalance from causing one battery to recharge another, thereby avoiding the efficiency degradation and lifetime reduction that occur in traditional parallel connections, while still achieving extended operational duration.
Solution Approach 2:
The switching mechanism incorporates feedback from the battery packs' charge states and performance metrics. This feedback allows the system to intelligently select which battery pack to use, preventing inefficient operation and extending battery lifetime by avoiding the harmful effects of voltage imbalance and unnecessary recharging cycles.
3Power
If multiple battery packs are connected in parallel to increase electric quantity, then the power availability is improved, but unbalanced voltages cause one battery pack to recharge the other, resulting in unnecessary power consumption
Solution Approach 1:
The system dynamically switches between battery packs based on real-time charge state monitoring. This dynamic switching ensures that power is drawn from the most suitable battery pack at any given time, maintaining high power availability while preventing the energy-wasting recharging phenomenon that occurs in static parallel connections with unbalanced voltages.
Solution Approach 2:
Each battery pack serves itself independently through the switching mechanism, which directs the load controller to draw power from the appropriate battery pack based on its charge state. This self-service approach eliminates the need for one battery to recharge another, thereby preventing unnecessary energy consumption while maintaining adequate power availability.

AI summary
A load control system includes a power switching device and a control device, wherein the power switching device includes a first power input port, a second power input port and a power output port. The first power input port and the second power input port are electrically connected to a first battery and a second battery respectively, and the power output port is electrically connected to the control device. The power output port receives the power which is input to the first power input port or the second power input port so as to supply the power to the control device. The control device is adapted to control a load to switch and to control the power switching device to utilize the power from the first power input port and the second power input port alternatively, thereby extending the respective usage time of the first battery and the second battery.
