Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple charging stations are installed in major base facilities, then charging capacity and service quality are improved, but system complexity and infrastructure cost increase
Solution Approach 1:
The patent combines multiple charging stations into a single multi-channel charging system that can serve multiple vehicles simultaneously through a unified control platform. This merging approach increases charging capacity while managing system complexity through centralized control rather than separate independent systems.
Solution Approach 2:
The charging system is designed with multi-functionality to handle various charging modes including simultaneous charging of multiple vehicles, vehicle-to-vehicle power sharing, and integration with renewable energy sources. This universal design allows a single system to perform multiple functions that would otherwise require separate specialized systems.
2Productivity
If simultaneous charging of multiple vehicles is enabled, then charging efficiency is improved, but power distribution complexity and control difficulty increase
Solution Approach 1:
The system employs feedback mechanisms where the controller continuously monitors the charging status, power consumption, and battery states of all connected vehicles. Based on this real-time feedback, the controller dynamically adjusts power distribution to optimize charging efficiency while managing control complexity through automated decision-making algorithms.
Solution Approach 2:
The power distribution system is designed to be dynamic rather than static, allowing real-time adjustment of power allocation based on changing conditions such as battery charge levels, charging priorities, and available power from renewable sources. This dynamic approach enables efficient simultaneous charging while adapting to varying system states without requiring complex manual control.
3Use of energy by moving object
If vehicle-to-vehicle power sharing is implemented, then energy utilization efficiency is improved, but system reliability and safety requirements increase
Solution Approach 1:
The charging system acts as an intermediary between vehicles enabling power sharing. Rather than direct vehicle-to-vehicle power transfer, the charging system mediates the power exchange, monitoring and controlling the flow to ensure safety and reliability. This intermediary approach maintains system reliability while enabling efficient energy utilization through vehicle-to-vehicle power sharing.
4Use of energy by moving object
If renewable energy integration is increased, then sustainability and energy efficiency are improved, but power stability and grid reliability may be affected
Solution Approach 1:
The system incorporates preliminary actions by storing energy from renewable sources when available and preparing power distribution in advance. Energy storage systems are charged during periods of high renewable energy availability, and this stored energy is then used during periods of low renewable generation to maintain power stability and reliability.
