Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric vehicles use conventional charging methods at charging stations, then they can be recharged, but charging infrastructure is limited and charging is not easy
Solution Approach 1:
The electric vehicle is equipped with a wind power generation system that includes a turbine, rotor, and stator, enabling the vehicle to generate its own electricity while traveling. The turbine rotates under wind pressure to drive the rotor, which generates electrical energy through electromagnetic induction in the stator, charging the battery without external charging stations
Solution Approach 2:
The vehicle combines multiple functions: the turbine serves both as a wind power generator and an air inlet mechanism, the power generation unit provides both propulsion assistance and battery charging, and the control unit manages both motor control and power generation control, creating a multi-functional integrated system
2Duration of action of moving object
If electric vehicles rely on external charging stations, then battery can be recharged, but traveling distance is limited by charging station availability
Solution Approach 1:
The vehicle performs preliminary power generation during travel by capturing wind energy along the route. The turbine continuously converts wind kinetic energy into electrical energy that is stored in the battery, preparing energy reserves in advance rather than waiting for charging stations
Solution Approach 2:
The wind power generation system operates continuously during vehicle travel, with the turbine constantly converting wind energy to electrical energy. This continuous power generation extends the effective operating duration of the vehicle beyond what would be possible with intermittent charging station stops
3Use of energy by moving object
If electric vehicles use fossil fuel-powered vehicles as alternative, then energy security is improved, but air pollution and environmental problems worsen
Solution Approach 1:
The patent replaces the chemical combustion system of fossil fuels with a wind-powered mechanical-electrical system. The turbine converts wind kinetic energy to mechanical rotation, which drives the rotor to generate electricity through electromagnetic induction, eliminating exhaust emissions while maintaining energy security
Solution Approach 2:
The vehicle changes the energy source parameter from chemical energy (fossil fuels) to kinetic energy (wind). By utilizing wind power generation, the system transforms the fundamental energy input parameter, achieving clean energy operation while maintaining adequate energy supply for vehicle operation
4Use of energy by moving object
If electric vehicles charge at charging stations, then battery is recharged, but charging costs are high
Solution Approach 1:
The vehicle generates its own charging energy through the wind power system, eliminating or reducing the need to purchase electricity from external charging stations. The self-generated electrical energy from wind power directly charges the battery, reducing operational costs
