Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric vehicle charging infrastructure is expanded, then charging availability improves, but infrastructure complexity increases
Solution Approach 1:
The patent introduces a route determination module as an intermediary system that mediates between the driver and the complex charging infrastructure. This module automatically plans routes considering battery status, charging location availability, and journey requirements, shielding users from infrastructure complexity while utilizing expanded charging networks effectively
2Speed
If fast charging infrastructure is increased, then recharging speed improves, but infrastructure cost and complexity increase
Solution Approach 1:
The route determination module dynamically adjusts charging plans based on real-time battery status monitoring and journey requirements. It optimizes the mix of fast and standard charging stops along the route, adapting to varying infrastructure availability without requiring uniform fast charging deployment everywhere
Solution Approach 2:
The system changes operational parameters by adjusting charging duration, charging power levels, and stop frequency based on battery state of charge, journey time constraints, and infrastructure characteristics, maximizing efficiency without requiring maximum fast charging infrastructure deployment
3Measurement precision
If charging network data is integrated into routing, then route planning accuracy improves, but system complexity increases
Solution Approach 1:
The patent merges the route determination function with battery status monitoring and charging location database integration into a unified navigation system. This combination provides accurate charge-based routing while consolidating system complexity into a single integrated module rather than separate independent systems
4Reliability
If battery status monitoring is implemented, then energy management improves, but device complexity increases
Solution Approach 1:
The battery status monitoring module operates autonomously, continuously tracking battery charge levels and autonomously providing data to the route determination system. This self-service approach improves energy management reliability without requiring complex manual intervention or additional control systems
Data Source
AI summary
An electric vehicle routing system comprising a route determination module configured to receive, via a graphical user interface (GUI) module, user input data defining, for a desired journey of a vehicle in which the vehicle routing system is installed, a start location in a road network, a destination location in the road network, and at least one waypoint in the road network. On the basis of the received user input data, data received from a vehicle battery status monitoring module, data retrieved from a road network storage database and data retrieved from a charging network storage database, the route determination module determines at least one route in the road network from the start location to the destination location via the at least one waypoint and transmits data associated with the at least one determined route to the GUI module.
