Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional crank drive mechanism is used to convert piston motion to rotary motion, then the engine can generate torque, but mechanical dead points are created and the transmitted force decreases in a sinusoidal curve
Solution Approach 1:
The invention replaces the conventional crank mechanism with a spherical piston design that moves in a circular path within the cylindrical combustion chamber. The piston's spherical shape and circular motion path eliminate mechanical dead points and maintain constant torque transmission throughout the entire rotation cycle, converting the sinusoidal force variation into uniform rotational force.
Solution Approach 2:
The invention extracts and eliminates the crank mechanism entirely from the engine design. By removing the connecting rod and crankshaft assembly, the patent eliminates the source of mechanical dead points and sinusoidal force variation, achieving direct and continuous torque transmission from the spherical piston to the output shaft.
2Ease of operation
If a crank drive mechanism is used, then piston motion can be converted to rotary motion, but the transmitted power decreases towards dead points
Solution Approach 1:
The spherical piston design with circular motion path ensures that the force vector remains tangential to the rotation throughout the entire cycle. This geometric configuration maintains constant torque transmission without the force drops characteristic of crank mechanisms, as the spherical piston continuously pushes against the circular path without dead centers.
3Use of energy by moving object
If conventional reciprocating piston engines are used, then fuel combustion can drive the piston, but fuel efficiency is reduced due to mechanical losses
Solution Approach 1:
By removing the connecting rod and crank mechanism, the invention eliminates the mechanical losses associated with these components. The spherical piston directly converts combustion pressure into rotational motion, reducing friction, inertial losses, and mechanical inefficiencies while improving overall fuel energy utilization.
Solution Approach 2:
The spherical piston design with circular motion path creates more efficient force transmission by maintaining constant tangential force throughout the rotation. This geometric configuration reduces mechanical losses compared to the reciprocating motion of conventional pistons, improving fuel efficiency through better energy conversion.
