Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rotational wind energy receivers are used, then the system structure is simple, but the coefficient of wind energy usage cannot be maintained at maximum across a wide range of wind speeds
Solution Approach 1:
The patent applies dynamics by transitioning from fixed rotational wind energy receivers to movable linear modules that can dynamically adjust their position, orientation, and operational status. The modules move linearly along guide belts and can be continuously added or removed from the system, enabling real-time adaptation to varying wind conditions while maintaining maximum energy usage efficiency across different wind speeds.
Solution Approach 2:
The system is divided into multiple independent modular units that can operate separately or in combination. Each module contains its own wind energy receiver, propulsion system, and generator components, allowing selective deployment and removal of individual modules based on wind conditions without affecting the entire system structure.
2Adaptability or versatility
If the number of modules is fixed, then the system structure is stable, but the total area of operating wind energy receivers cannot be adjusted to match varying wind speeds
Solution Approach 1:
The system enables dynamic adjustment of the total operating area by continuously adding or removing modules from the guide belts based on real-time wind speed measurements. This dynamic reconfiguration allows the total receiver area to scale with wind conditions while maintaining system operational stability through standardized module interfaces and control protocols.
Solution Approach 2:
The patent changes the operational parameter of total receiver area by adjusting the number of active modules in the system. This parameter change is achieved through controlled module addition or removal, allowing the system to optimize its wind energy capture area according to varying wind speeds without altering the fundamental system architecture.
3Use of energy by moving object
If wind energy receivers operate at low translational speed, then energy conversion is efficient, but aerodynamic noise and infra sound waves are generated
Solution Approach 1:
The system controls the harmful effects by adjusting operational parameters including module translational speed, aerodynamic profile orientation, and module spacing. By optimizing these parameters, the system maintains efficient energy conversion while minimizing aerodynamic noise and infra sound generation through controlled operation within specific speed and orientation ranges.
4Object-generated harmful factors
If high speed operation is used to avoid noise, then aerodynamic noise is reduced, but the system generates high capacity infra sound waves dangerous to animals and people
Solution Approach 1:
The patent addresses this contradiction by implementing comprehensive parameter control including module speed, aerodynamic profile angle of attack, and module distribution along the guide belts. This multi-parameter optimization enables the system to operate in a regime that minimizes both aerodynamic noise and infra sound generation, ensuring safe operation near populated areas while maintaining energy conversion efficiency.
