Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited energy storage capacity of electric vehicle batteries and the inefficiencies in charging systems restrict the range and practicality of electric battery-powered vehicles, while also increasing energy demands on public power systems.
Innovation Solution
A drive system for electric vehicles incorporating a chassis with motors attached to wheels that generate electricity to charge the battery system, combined with a magnet-based acceleration system using rare earth Neodymium magnets for propulsion, where the movement of a magnet element relative to a stationary magnet creates a repelling force to drive the vehicle, and hub motors generate electricity as wheels rotate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery system size is increased to extend driving range, then the energy storage capacity is improved, but the vehicle weight and cost increase
Solution Approach 1:
The vehicle generates its own charging energy through the electromagnetic propulsion system during normal operation. The moving magnetic elements cut through stationary magnetic fields to induce electrical current that charges the battery system, allowing the vehicle to self-recharge without external infrastructure or oversized batteries.
2Quantity of substance
If traditional charging systems are used, then the battery system can be recharged, but the energy demand on public power systems increases and charging infrastructure cost increases
Solution Approach 1:
The vehicle becomes self-sufficient for charging by generating electrical energy during propulsion. The electromagnetic system serves dual purposes: propelling the vehicle forward and simultaneously generating charging current for the battery system, eliminating dependence on external power infrastructure.
Solution Approach 2:
The propulsion system and charging system are merged into a single electromagnetic mechanism. The same magnetic fields and moving elements used for propulsion also generate electrical current for charging, combining two previously separate functions into one integrated system.
3Productivity
If electromagnetic propulsion system is implemented, then the vehicle can generate its own charging energy, but the device complexity increases
Solution Approach 1:
The electromagnetic propulsion system performs multiple functions simultaneously: it propels the vehicle through magnetic repulsion/attraction and generates electrical current for charging the battery system. This multi-functionality reduces the need for separate charging infrastructure and simplifies the overall system architecture.
