1Adaptability or versatility

If a single control algorithm is used for managing charging infrastructure, then the system is simple to operate, but it cannot adapt to varying user needs and technical constraints, leading to reduced quality of service

Engineering Contradiction:
Improveadaptability to user needsVSAvoidcomplexity of control system
Core Design Contradiction:

Solution Approach 1:

The system dynamically selects control algorithms based on real-time conditions including user needs, vehicle characteristics, and infrastructure constraints. Instead of using a fixed algorithm, the system adapts its control strategy by evaluating multiple algorithms and selecting the most appropriate one for each charging scenario, thereby achieving adaptability without permanent system complexity.

Inventive Principle:

Solution Approach 2:

The system changes the parameter of algorithm selection based on varying conditions. By monitoring parameters such as user preferences, vehicle battery state, charging speed requirements, and infrastructure capacity, the system adjusts which control algorithm is deployed, allowing the same infrastructure to serve diverse needs through parameter-driven algorithm selection.

Inventive Principle:

2Reliability

If multiple control algorithms are evaluated and selected based on performance indicators, then the quality of service is optimized, but the computational complexity and time required for algorithm selection increases

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary evaluation of control algorithms by simulating their performance under predefined scenarios before actual deployment. By pre-assessing algorithms against various charging scenarios and establishing performance indicators in advance, the system reduces the time required for real-time decision-making, as the selection process relies on pre-computed performance data rather than exhaustive real-time analysis.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses simplified performance indicator calculations that require minimal computational resources. Rather than implementing complex, time-consuming simulations for each algorithm selection, the system employs lightweight evaluation metrics that can be quickly computed, sacrificing some depth of analysis for the benefit of rapid algorithm selection in real-time operations.

Solution Approach 1:

The system incorporates feedback from infrastructure constraints into the algorithm selection process. By continuously monitoring actual power delivery capacity, vehicle requirements, and charging progress, the system adjusts its algorithm selection to ensure that chosen algorithms are compatible with current infrastructure capabilities, preventing service interruptions caused by mismatched control strategies.

Inventive Principle:

Solution Approach 2:

The system takes preliminary actions to prevent service interruptions by evaluating infrastructure constraints before selecting control algorithms. By assessing power delivery limitations, connector types, and charging station capabilities in advance, the system chooses algorithms that are pre-suitable for the given infrastructure, thereby avoiding situations where algorithm execution would fail or cause service disruptions.
