1Adaptability or versatility

If a decentralized charging system is used, then installation flexibility is improved, but control and monitoring capabilities deteriorate

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidcontrol and monitoring capabilities

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into autonomous parking station control units that can operate independently, each managing its own charging operations. This segmentation allows decentralized installation while maintaining individual control capabilities at each station level.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A centralized control center acts as an intermediary between multiple parking stations and users. It receives data from individual stations, performs global optimization, and coordinates charging operations across the network, thereby providing system-wide control without compromising individual station autonomy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If individual vehicle parameter optimization is implemented, then charging efficiency is improved, but system complexity increases

Engineering Contradiction:

Solution Approach 1:

The control system automatically optimizes charging parameters for each vehicle based on its specific characteristics and current state. The system performs self-adjustment of charging currents, voltages, and timing without requiring manual intervention, thereby improving efficiency while keeping the user interface simple.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors vehicle battery status, charging rate, and power consumption, using this feedback to dynamically adjust charging parameters. This closed-loop control enables efficient individualized charging while automating the complexity of parameter management.

Inventive Principle:

Principle #23Feedback

3Reliability
