Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dense charging infrastructure with many charging devices is deployed to enable economical electric vehicle charging, then the ease of operation and accessibility for electric vehicle users is improved, but the load on the electrical power distribution system increases significantly
Solution Approach 1:
The patent implements peer-to-peer energy sharing where electric vehicle owners can directly share their excess battery capacity with other users. The system allows vehicle owners to act as both consumers and providers of electrical energy, eliminating the need for centralized charging infrastructure. Users can offer their battery capacity through a digital platform, and the system automatically manages the energy exchange, enabling charging accessibility without additional power distribution infrastructure.
Solution Approach 2:
The patent creates a multi-functional system where electric vehicle batteries serve dual purposes: as energy storage for vehicle operation and as distributed power supply for charging other vehicles. The same battery resource can simultaneously function as a mobile power plant, reducing the need for dedicated charging devices and power distribution infrastructure while maintaining charging accessibility.
2Reliability
If centralized charging infrastructure is used to recharge electric vehicles, then the reliability of power supply is improved, but the device complexity and infrastructure cost increase
Solution Approach 1:
The patent segments the centralized charging infrastructure into distributed, autonomous units located in individual electric vehicles. Instead of one centralized charging station, the system divides the charging function across multiple independent vehicle batteries. Each vehicle becomes an independent charging unit, simplifying the overall infrastructure while maintaining reliability through distribution across multiple nodes.
Solution Approach 2:
The patent introduces a digital platform as an intermediary that coordinates peer-to-peer energy sharing without requiring physical charging infrastructure. The platform matches energy providers and consumers, manages transactions, and coordinates battery-to-battery energy transfer, eliminating the need for complex charging devices while maintaining system reliability through digital coordination.
3Ease of operation
If electric vehicles are charged from the electrical grid, then the ease of operation is improved, but the loss of energy during transmission and distribution increases
Solution Approach 1:
The patent enables electric vehicle owners to self-supply energy to other users from their own battery capacity, eliminating the need for energy transmission through the electrical grid. This direct peer-to-peer energy sharing removes transmission losses entirely, as energy is transferred vehicle-to-vehicle without passing through power distribution infrastructure, while maintaining charging convenience through the digital platform.
