Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple rechargeable power units are used to supply power to a load, then power supply reliability and operational flexibility are improved, but the system complexity and control difficulty increase
Solution Approach 1:
The patent divides the power supply system into multiple independent rechargeable power units (first rechargeable power unit, second rechargeable power unit, etc.), each capable of independently supplying power to the load. This segmentation allows the system to maintain reliability through redundancy while managing complexity by treating each unit as a modular component with standardized control interfaces.
Solution Approach 2:
The control device dynamically adjusts the power distribution among multiple rechargeable power units based on real-time operational conditions, power consumption requirements, and battery states. This dynamic control enables the system to adapt to varying load demands and maintain optimal performance while managing complexity through intelligent algorithms that automatically balance power allocation.
2Duration of action of stationary object
If a solitary rechargeable power unit is used, then the system is simple and easy to control, but the power unit deteriorates rapidly and has limited operational lifespan
Solution Approach 1:
The patent segments the power supply function across multiple rechargeable power units, allowing the workload to be distributed and shared. This reduces the discharge depth and operational stress on each individual unit, thereby extending their lifespan and duration of action while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The control device monitors the state of charge and health of each rechargeable power unit, strategically managing their discharge and charge cycles. By rotating usage among multiple units and recovering energy through charging when not in use, the system extends the overall operational lifespan of the power sources while maintaining simple control logic for each individual unit.
3Productivity
If multiple rechargeable power units simultaneously supply power, then power utilization efficiency is enhanced, but the control complexity and power distribution management increase
Solution Approach 1:
The control device implements feedback mechanisms by continuously monitoring the power consumption of the load, the state of charge, and the operational status of each rechargeable power unit. Based on this feedback, the control device automatically adjusts the power distribution among units to optimize utilization efficiency while managing control complexity through closed-loop control algorithms that adapt to real-time conditions.
Solution Approach 2:
The control device dynamically changes operational parameters such as power output levels, charge/discharge rates, and activation states of different rechargeable power units based on load requirements and battery conditions. This parameter optimization enhances power utilization efficiency by matching supply capabilities with actual demand while keeping control complexity manageable through automated parameter adjustment rather than manual intervention.

AI summary
A method for distributing power using multiple power sources is performed by a control device electrically connected to multiple rechargeable power units and a load. The control device creates an output power reference table according to multiple power setting values, output power ranges and battery efficiencies of the multiple rechargeable power units. The output power reference table includes the power setting values and power distribution information corresponding to the power setting values. When receiving a consumed power value of the load, the control device selects corresponding power setting value and power distribution information in the output power reference table and controls the multiple rechargeable power units to simultaneously output power to the load according to the power distribution information. By referring to the output power values of all the rechargeable power units and allocating power outputted from all the rechargeable power units, power utilization efficiency can be enhanced.
