Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electric car charging is expanded to meet increasing demand, then charging capacity and service coverage are improved, but public electricity networks experience severe pressure and power outages
Solution Approach 1:
The patent divides the centralized grid-connected charging system into distributed autonomous charging units that operate independently. Each charging unit is a self-contained module with its own generator and control system, allowing charging capacity to be expanded without overloading the public electricity network.
Solution Approach 2:
The patent extracts the power generation function from the public electricity network by equipping charging units with independent soundless electric generators. This allows the charging system to operate autonomously without drawing excessive power from the grid, thus avoiding network overload and power outages.
2Ease of manufacture
If traditional grid-connected charging stations are installed, then charging infrastructure is provided, but installation costs are high and construction time is lengthy
Solution Approach 1:
The charging infrastructure is divided into modular autonomous charging units that can be deployed independently. Each unit is a complete, self-contained package requiring minimal infrastructure work, enabling rapid deployment without lengthy construction processes.
Solution Approach 2:
The charging units are designed to be self-sufficient with integrated generators and control systems, eliminating the need for complex grid connections and extensive infrastructure development. This self-service capability dramatically reduces both installation cost and construction time.
3Ease of operation
If first-level charging is used with standard electricity networks, then charging is accessible, but charging time is excessively long (16-18 hours)
Solution Approach 1:
The patent changes the power output parameter of the charging system by equipping units with high-capacity soundless electric generators that can deliver significantly higher charging power than standard first-level charging. This enables fast charging while maintaining accessibility through distributed deployment.
4Use of energy by moving object
If charging stations are connected to public electricity networks, then power supply is available, but network stress increases and carbon emissions increase
Solution Approach 1:
The patent extracts the power supply function from the public electricity network by integrating soundless electric generators into autonomous charging units. This eliminates dependence on grid power, reducing network stress and avoiding the carbon emissions associated with conventional electricity generation.
Solution Approach 2:
The patent converts the previously harmful reliance on carbon-intensive grid electricity into a beneficial autonomous power generation system using soundless electric generators, thereby eliminating carbon emissions while ensuring energy availability.

AI summary
A mobile and stationed charging system for electric cars designed to expand the charging infrastructure instead of the limited charging stations connected to public electricity networks, charging on the power of soundless electric generators to avoid noise, and operating on gasoline, diesel, natural gas, or hydrogen. To protect the environment, palladium is used in the catalytic converter to purify the exhaust gas, and a third level rapid charging device “high power charger” (HPC) is added. Fixed stations are integrated within the scope of traditional gas stations and may share with them the use of one of the fuels. Mostly they are independent. They can be installed and operated anywhere, either mobile stations on conventional or electric self-driving cars or with a driver with sufficient fuel tanks, with communication devices to meet charging requests anywhere. The charging system could be a solution for expanding the charging infrastructure.
