Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electric vehicles charge at charging stations, then the battery is recharged, but charging infrastructure is limited and costs are high
Solution Approach 1:
The electric vehicle generates its own electricity through wind power generation during travel, eliminating dependence on external charging stations. The turbine rotates with wind flow to generate electrical energy that charges the battery, enabling the vehicle to serve its own charging needs independently.
Solution Approach 2:
The air inlet structure dynamically opens during vehicle travel to allow wind flow to the turbine, and closes when stationary to prevent water ingress. The controller adjusts the air inlet state based on vehicle motion status, optimizing both power generation and protection functions.
2Duration of action of moving object
If fossil fuels are used for charging, then vehicles can travel long distances, but air pollution increases
Solution Approach 1:
The patent replaces the chemical combustion system (fossil fuel engines) with a wind-powered mechanical generation system. The turbine converts wind kinetic energy directly into electrical energy through mechanical rotation, eliminating combustion processes and associated air pollution while enabling long-distance travel.
3Productivity
If the air inlet is always open to allow wind flow, then power generation is maximized, but water and foreign substances can enter during rain or stationary periods
Solution Approach 1:
The air inlet is designed as a dynamic structure that changes state based on vehicle operation conditions. It opens during travel to maximize wind flow and power generation, then closes during stationary periods or rain to prevent water and foreign substance ingress, protecting the turbine and electrical components.
Solution Approach 2:
The controller monitors vehicle travel state and weather conditions to automatically control the air inlet opening/closing. When the vehicle is traveling, the controller opens the air inlet to enable power generation; when stationary or rain is detected, it closes the inlet to prevent damage, creating a feedback-controlled protection system.
