Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single battery group is used for both power supply and standby modes, then the device complexity is reduced, but the reliability of power supply during blackouts deteriorates due to potential imbalances and inefficiencies
Solution Approach 1:
The battery system is divided into multiple battery groups (first battery group and second battery group) that can be dynamically allocated to different functional modes. This segmentation allows one battery group to serve as power supply while another serves as standby, thereby improving reliability through redundancy and load distribution.
Solution Approach 2:
The patent implements dynamic allocation of battery groups to power supply and standby modes based on predetermined conditions such as state of charge, usage count, and temperature. The control unit continuously monitors these parameters and switches the functional roles of battery groups accordingly, ensuring optimal reliability under varying operating conditions.
2Reliability
If multiple battery groups are used with dynamic allocation, then the reliability of power supply is improved, but the device complexity increases due to additional battery groups and control mechanisms
Solution Approach 1:
Each battery group is designed to be multi-functional, capable of operating in either power supply mode or standby mode. This universality allows the system to maintain reliability through dynamic role assignment while avoiding the need for dedicated hardware for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The control unit monitors and compares operational parameters (state of charge, usage count, temperature) of different battery groups and dynamically changes their functional assignment based on these parameter variations. This parameter-driven approach enables automatic optimization without requiring complex manual intervention or overly sophisticated control systems.
3Ease of operation
If a single battery group is used, then the ease of operation is maintained, but the productivity of energy usage deteriorates due to imbalances in charge/discharge operations
Solution Approach 1:
The control unit continuously monitors the operational state of battery groups including state of charge, usage count, and temperature, and uses this feedback to dynamically allocate which battery group serves power supply and which serves standby. This feedback mechanism optimizes energy usage by preventing over-discharge and thermal accumulation, thereby improving productivity while maintaining ease of operation through automatic control.
4Ease of operation
If battery groups operate in fixed modes, then the ease of operation is maintained, but the adaptability to different emergency situations deteriorates
Solution Approach 1:
The patent implements dynamic mode allocation where battery groups can switch between power supply and standby roles based on real-time monitoring of operational parameters. This dynamic adaptability allows the system to respond flexibly to different emergency situations (blackouts, overloads, thermal events) while maintaining ease of operation through automated control that requires no user intervention.

AI summary
A power supply apparatus is provided comprising an input terminal adapted to receive an external AC power; an output terminal adapted to output a first AC power, a first power conversion unit adapted to convert the received external AC power to a first DC power and outputs the first DC power; a second power conversion unit adapted to convert a DC power to a first AC power and outputs the first AC power to the output terminal; a first node electrically connected between the output of the first power conversion unit and the input of the second power conversion unit; a control unit adapted to control the operations of the first and second power conversion units; and a first and a second battery group each connected to the control unit and electrically connectable to first node. The first and second battery groups are distinct from each other and can be separately connected to the first node. The control unit is adapted to dynamically allocate one of the first and the second battery group as a first dynamic battery group and the other of the first and the second battery group as a second dynamic battery group depending on a predetermined condition, wherein the first dynamical group acts in a power supply mode, and the second dynamic battery group acts in a standby mode.
