Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional crank drive mechanisms are used, then the engine can convert oscillating piston motion into rotary motion, but the torque output becomes non-uniform and mechanical dead centers are encountered
Solution Approach 1:
The patent replaces the conventional mechanical crank drive transmission with a hydraulic transmission system. The hydraulic system uses fluid pressure to transmit force from the piston to the drive shaft, eliminating the need for crank mechanisms with connecting rods. This substitution resolves the technical contradiction by providing uniform torque output through hydraulic pressure while simplifying the mechanical transmission structure.
Solution Approach 2:
The patent employs a hydraulic transmission system where hydraulic fluid transmits the force generated by piston movement to the drive shaft. The hydraulic cylinder and piston arrangement converts linear piston motion into rotary motion of the drive shaft through fluid pressure, achieving uniform torque across the entire rotation cycle without mechanical dead centers.
2Power
If flywheels are added to smooth torque output, then torque uniformity improves, but the engine size and weight increase
Solution Approach 1:
The patent eliminates the need for flywheels by replacing the mechanical crank drive with a hydraulic transmission system. The hydraulic system inherently provides uniform torque transmission through fluid pressure, removing the requirement for heavy flywheels to smooth torque fluctuations. This resolves the contradiction by achieving torque uniformity without increasing engine weight.
3Power
If conventional mechanical transmissions are used, then power can be transmitted from piston to crankshaft, but high torque at low speeds is limited by mechanical dead centers
Solution Approach 1:
The patent uses a hydraulic transmission system where hydraulic fluid continuously transmits force from the piston to the drive shaft throughout the entire rotation cycle. The hydraulic pressure maintains constant force transmission even when the piston is at extreme positions, eliminating mechanical dead centers and enabling high torque output at low speeds with continuous operational smoothness.
Solution Approach 2:
The patent replaces the mechanical crank connection with a hydraulic force transmission system. This substitution allows the drive shaft to receive continuous rotational force from the piston through hydraulic pressure, eliminating the dead center positions inherent in mechanical crank mechanisms and enabling smooth operation at low speeds with high torque capability.
