Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If charging stations are limited to niche areas, then infrastructure cost is reduced, but charging convenience and accessibility deteriorate
Solution Approach 1:
The patent segments the charging infrastructure into multiple distributed charging stations across different geographic areas, allowing users to access charging services at various locations rather than relying on a single centralized facility. This segmentation enables broader accessibility while managing infrastructure costs through distributed deployment.
Solution Approach 2:
The charging station system is designed to serve multiple functions and user types, accommodating different electric vehicle models and charging needs at a single location. The universal design allows the infrastructure to be deployed in diverse settings (residential, commercial, public) rather than being limited to niche applications.
2Loss of time
If charging rate is increased to reduce recharging time, then charging speed is improved, but energy loss and system stress increase
Solution Approach 1:
The charging system dynamically adjusts the charging rate based on real-time conditions including battery state of charge, temperature, grid availability, and user preferences. The controller modulates power delivery to optimize charging speed while preventing excessive energy loss and system stress through adaptive control.
Solution Approach 2:
The system changes multiple parameters during the charging process including voltage, current, and power levels to maintain optimal charging efficiency. By continuously adjusting these parameters based on battery characteristics and environmental conditions, the system reduces energy loss while maintaining acceptable charging speeds.
3Ease of operation
If multiple charging stations are deployed across wide areas, then charging accessibility is improved, but infrastructure complexity increases
Solution Approach 1:
The patent introduces a central controller and communication network as intermediaries that coordinate between multiple distributed charging stations and the central management system. This intermediary layer simplifies the overall infrastructure complexity by providing centralized monitoring, control, and data management across the distributed network of charging stations.
Data Source
AI summary
A method for determining an availability of an electric vehicle charging station is disclosed. The method includes: obtaining a distance between a mobile device and the electric vehicle charging station using a first geolocation information and a second geolocation information; based on the determined distance, determining an availability of the electric vehicle charging station; and sending a message to a user regarding the determined availability of the electric vehicle charging station.
