Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If constant length rotors are used to provide continuous rotational motion, then the rotational continuity is maintained, but the torque efficiency and power generation capability are limited
Solution Approach 1:
The rotor is divided into multiple variable length arms that can independently adjust their lengths. This segmentation allows each arm to optimize its length for maximum torque generation at different rotational positions, thereby improving overall power generation capability without requiring a completely complex new structure
Solution Approach 2:
The rotor arms are designed with variable length capability, transitioning from static constant-length arms to dynamic adjustable-length arms. This allows the rotor to adapt its geometry during operation, optimizing torque efficiency and power output while maintaining continuous rotational motion
2Loss of energy
If low-frictional elements such as bearings are used in rotational components, then friction is reduced, but power efficiency can still be improved further
Solution Approach 1:
The patent replaces traditional bearing-based friction reduction mechanisms with a variable length arm mechanism that optimizes torque generation through geometric adaptation. This substitution aims to reduce frictional losses while avoiding the complexity of multiple bearing assemblies
3Use of energy by moving object
If traditional wind turbine structures are used for energy conversion, then the conversion from wind energy to rotational motion is achieved, but torque efficiency and power generation capability are limited
Solution Approach 1:
The rotor arms are designed with variable length capability, transitioning from static constant-length arms to dynamic adjustable-length arms. This allows the rotor to adapt its geometry during operation, optimizing torque efficiency and power output while maintaining continuous rotational motion

AI summary
A rotary machine for a power system includes a rotary drum having a rotational center shaft, a stationary half gear including a generally circular non-geared portion and a geared portion having gear teeth, and at least one pair of revolving gears formed of two revolving gears symmetrically positioned about the center shaft and configured to simultaneously revolve around the stationary half gear. At least one rack shaft is operably coupled, directly or indirectly, to the revolving gears to reciprocate back and forth upon rotation of the revolving gears, and as the revolving gears revolve around the stationary half gear, one of the two revolving gears is configured to have gear engagement with the geared portion of the stationary half gear, while the other revolving gear is floating over the non-geared portion of the stationary half gear.
