Solution Overview
Problem
Conventional steam turbines and internal combustion engines face inefficiencies due to energy loss from friction and the challenge of achieving high torque at lower RPM, which also leads to issues like increased weight and bearing failure.

A high-efficiency sine rotary engine is designed with a rotor housing, a power shaft eccentrically positioned, a reciprocating rotor performing linear and rotational motion, and an eccentric shaft connected to the reciprocating rotor for constant rotational orbit guidance, reducing friction and enhancing power transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional steam turbines rotate blades by pushing them, then the turbine can generate power, but energy loss occurs due to friction and not all steam pressure can effectively rotate the blades
Solution Approach 1:
The patent employs curved inner surfaces and arch-shaped grooves in the rotor housing to guide fluid flow and reduce turbulence. The curved geometry allows for smoother fluid passage, reducing energy loss from chaotic flow patterns while maintaining effective pressure application on the power shaft.
Solution Approach 2:
The invention replaces the conventional blade-pushing mechanism with a direct fluid pressure system acting on an eccentric power shaft. This substitution eliminates the intermediate blade component, reducing friction losses and improving direct energy transfer from fluid pressure to rotational motion.
2Power
If a reducer is installed on the power shaft to lower RPM and increase torque, then high torque at lower RPM is achieved, but weight increases, energy loss occurs, and bearing failure risk increases
Solution Approach 1:
The patent extracts and eliminates the reducer component from the system by designing the sine rotary engine to naturally produce high torque at lower RPM through its inherent mechanical geometry. The eccentric power shaft and reciprocating rotor mechanism directly generate the desired torque characteristics without requiring external speed reduction gearing, thereby removing the associated energy losses and maintenance issues.
3Power
If the reciprocating rotor performs linear reciprocating motion and rotational motion, then power transmission occurs, but frictional force and operating load increase
Solution Approach 1:
The patent introduces an arch-shaped groove as an intermediary element between the power shaft and rotor housing. This groove acts as a guiding mechanism that reduces direct frictional contact while maintaining the necessary mechanical guidance for the reciprocating rotor's motion, thereby reducing operating load and frictional force.
Solution Approach 2:
The invention changes the geometric parameters of the rotor housing inner surface to optimized curved profiles. These parameter changes create smoother motion paths for the reciprocating rotor, reducing abrupt directional changes and minimizing frictional forces during the reciprocating and rotational motions.
4Power
If fluid flows through the rotor housing, then power transmission occurs, but fluid backflow between inlet and outlet reduces efficiency
Solution Approach 1:
The patent uses curved inner surfaces and arch-shaped grooves to create a unidirectional fluid flow path through the rotor housing. The curved geometry design guides fluid from the inlet through the working chamber to the outlet, using pressure gradients and flow direction control to prevent backflow, thereby maintaining power transmission efficiency.
