Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed DC charging stations are used, then charging capability is provided, but mobility and availability are limited
Solution Approach 1:
The patent transforms the static charging station into a dynamic system where any vehicle with a discharging outlet can become a mobile charging source. The cable assembly enables dynamic reconfiguration of charging relationships between vehicles, eliminating fixed infrastructure and improving charging availability throughout the day and across different locations.
Solution Approach 2:
The cable assembly serves multiple functions: it can connect any discharging vehicle to any charging vehicle, enabling peer-to-peer charging. This universal interface allows any vehicle to potentially serve as both charger and chargee, creating a versatile charging network without fixed stations.
2Productivity
If fixed charging stations are deployed, then charging service is provided, but the quantity and distribution are limited
Solution Approach 1:
Vehicles serve themselves and each other through direct peer-to-peer charging connections. A vehicle with excess battery capacity can automatically or manually charge another vehicle without requiring external charging infrastructure, enabling the fleet to self-sustain its charging needs and expand service coverage without adding physical stations.
Solution Approach 2:
The patent merges the functions of charging station and vehicle into a single integrated system. The cable assembly combines power transmission, communication, and connection control into one unit, allowing vehicles to function as both energy sources and energy receivers, effectively multiplying the charging service coverage without increasing the number of physical charging stations.
