Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the system increases power supplying amounts from movable batteries to the grid through second control, then the electrical power resources provided to the grid are increased, but the complexity of control allocation and management increases
Solution Approach 1:
The patent segments the control strategy into two distinct control modes (first control for reducing charging amounts, second control for increasing power supplying amounts) and further divides the decision-making into hierarchical levels: the allocating unit performs high-level allocation decisions based on predicted usage situations, while the controlling module executes specific control actions. This segmentation simplifies the overall control complexity by breaking down the complex allocation problem into manageable segments with clear decision boundaries.
Solution Approach 2:
The patent applies preliminary action by using the estimating module to predict usage situations of movable batteries in advance, and the allocating unit to pre-allocate control strategies before actual power supply operations. By predicting future states and pre-determining allocation decisions, the system avoids complex real-time decision-making, thereby reducing control allocation complexity while ensuring optimal power resource provision to the grid.
2Adaptability or versatility
If the system uses both first control and second control for power allocation, then the flexibility in meeting grid power requirements is improved, but the difficulty of detecting and measuring optimal allocation strategies increases
Solution Approach 1:
The patent implements feedback mechanisms where the estimating module continuously monitors actual usage situations of movable batteries and compares them with predicted situations. The allocating unit uses this feedback information to adjust and optimize control allocation strategies dynamically. This feedback loop enables the system to learn from actual operations and automatically identify optimal allocation strategies, reducing the difficulty of detecting and measuring optimal solutions while maintaining high adaptability to grid power requirements.
3Device complexity
If the system preferentially allocates first control over second control, then the simplicity of control strategy is improved, but the amount of electrical power resources that can be provided to the grid may be limited
Solution Approach 1:
The patent applies dynamics by making the control allocation strategy adaptive rather than static. The allocating unit dynamically adjusts the preference between first control and second control based on real-time grid power requirements and predicted battery usage situations. When grid power demand is high, the system can shift preference toward second control (increasing power supplying amounts) to maximize power provision, while maintaining simpler overall strategy structure. This dynamic adjustment resolves the contradiction by allowing the system to maintain simplicity while adapting to conditions that maximize power resource provision.

AI summary
A system that controls charging of multiple movable batteries and a power supply from the multiple movable batteries to an outside, the system comprising: a controlling module that provides an electric power grid with an electrical power resource by performing at least one of a first control for reducing power charging amounts for the multiple movable batteries, or a second control for increasing power supplying amounts from the multiple movable batteries to the outside, in response to a first request for requesting power consumption to be reduced; and an allocating unit that allocates control, among the first control and the second control, with which each of the multiple movable batteries provide the electric power grid with an electrical power resource in each of multiple timeframes in a future, based on an amount of electrical power resources available to be provided to the electric power grid by each of the multiple movable batteries and an amount of electrical power resources required to be provided to the electric power grid, wherein the first control is preferentially allocated over the second control.
