Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional kinetic energy conversion methods are used, then energy conversion can occur, but the conversion efficiency is low
Solution Approach 1:
The rotor is divided into multiple cup-shaped blades instead of using a conventional solid rotor design. Each cup-shaped blade independently captures kinetic energy from the air flow, allowing for more efficient energy capture across different portions of the rotor surface. This segmentation enables better utilization of the air flow's kinetic energy, directly addressing the low conversion efficiency problem.
Solution Approach 2:
The patent employs cup-shaped blades with curved surfaces instead of flat or straight designs. The curved geometry of the cup-shaped blades optimizes the capture of kinetic energy from air flow by creating more effective aerodynamic interactions. This curvature principle improves the conversion efficiency by better matching the natural flow patterns of air, thereby increasing the overall energy conversion rate.
2Object-generated harmful factors
If battery capacity is increased to reduce pollution, then pollution reduction is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the wind energy conversion system with the vehicle's existing electrical system, integrating the rotor, generator, and battery charger into a unified assembly. This merging allows the vehicle to simultaneously generate electricity from wind energy while charging the battery, reducing the need for larger battery packs and thereby decreasing production-related pollution without significantly increasing overall device complexity.
Solution Approach 2:
The system enables the vehicle to self-charge by converting kinetic energy from air flow into electrical energy that directly charges the battery. This self-service capability reduces the burden on the battery pack size requirements, as the vehicle can replenish its energy supply during operation, thereby reducing the need for larger, more complex battery assemblies and associated production pollution.
