Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If motors or internal combustion engines are used to generate torque, then torque can be produced, but a large amount of energy is consumed
Solution Approach 1:
The patent replaces traditional electromagnetic motors or internal combustion engines with a control moment gyroscope-based mechanical system. The CMG utilizes conservation of angular momentum to generate torque through precession, eliminating the need for continuous energy input required by electromagnetic or combustion systems, thereby dramatically reducing energy consumption while maintaining torque generation capability
Solution Approach 2:
The control moment gyroscope generates torque through periodic modulation of the rotor's spin speed. By periodically accelerating and decelerating the high-speed rotor, the system creates precession motion that produces useful torque output, allowing torque generation with minimal net energy consumption over each cycle
2Force
If control moment gyroscopes generate torque in different directions, then torque can be generated, but the torque direction needs to be controlled to be unidirectional
Solution Approach 1:
The patent divides the torque generation function into two separate control moment gyroscopes, each responsible for generating torque in opposite directions. By independently controlling each CMG and using a unidirectional driving module, the system can select and combine torque from either CMG to produce unidirectional output torque, simplifying direction control while maintaining flexibility
Solution Approach 2:
The patent introduces a unidirectional driving module as an intermediary between the control moment gyroscopes and the load. This module acts as a mediator that receives torque from CMGs generating torque in different directions and outputs only unidirectional torque, effectively solving the direction control problem without requiring complex control algorithms
