Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If reciprocating motion conversion components (connecting rods, crankshafts, flywheels) are added to convert piston motion to rotation, then the engine can perform rotational work, but the structure becomes complex, weight increases, and transmission efficiency decreases
Solution Approach 1:
The patent extracts and removes the traditional reciprocating motion conversion components (connecting rods, crankshafts, flywheels) from the engine system. By eliminating these intermediate conversion components, the invention directly converts the rotational motion of the piston into useful work, thereby simplifying the structure while maintaining rotational work capability.
Solution Approach 2:
Instead of converting reciprocating motion to rotation through intermediate components, the patent inverts the approach by designing the piston itself to rotate and directly perform rotational work. This fundamental reversal of the motion conversion mechanism eliminates the need for traditional conversion components.

If reciprocating motion conversion components (connecting rods, crankshafts, flywheels) are added to convert piston motion to rotation, then the engine can perform rotational work, but weight increases and transmission efficiency decreases
Solution Approach 1:
The patent extracts and removes the heavy reciprocating motion conversion components (connecting rods, crankshafts, flywheels) from the engine system. By eliminating these intermediate conversion components, the invention directly converts the rotational motion of the piston into useful work, thereby simplifying the structure while maintaining rotational work capability.
3Power

Solution Approach 1:
The patent extracts and removes the reciprocating motion conversion components (connecting rods, crankshafts, flywheels) from the engine system. By eliminating these intermediate conversion components, the invention directly converts the rotational motion of the piston into useful work, reducing energy loss and improving transmission efficiency.
4Productivity
If combustion and compression are performed in the same cylinder sequentially, then the engine can complete the four-stroke cycle, but the structure becomes complex and energy conversion efficiency decreases
Solution Approach 1:
The patent segments the cylinder into two separate functional chambers: a combustion cylinder and a compression cylinder. Each cylinder performs its specific function independently, with the combustion cylinder handling combustion and power generation, while the compression cylinder handles air compression and intake. This segmentation simplifies the overall structure by eliminating the need for complex valve mechanisms and piston movements required for sequential four-stroke operations in a single cylinder.
Solution Approach 2:
The rotary piston design enables the system to perform multiple functions simultaneously - compression and combustion occur at the same time in different chambers, rather than sequentially in the same chamber. This multi-functionality approach simplifies the mechanical structure while maintaining complete combustion cycles.
