Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a spiral rotor with slider mechanism is used to convert reciprocating motion to rotary motion, then the conversion efficiency is improved, but the device complexity increases due to additional components and mechanical arrangements

Engineering Contradiction:

Improvemotion conversion efficiencyVSAvoidsystem structural complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the reciprocating motion mechanism and rotary motion output into a single integrated spiral rotor assembly. The slider moves directly along the spiral profile of the rotor, merging the conversion function into one compact component rather than requiring separate mechanisms for reciprocating and rotary motion.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention employs a spiral (curved) profile on the rotor surface instead of straight or angular geometries. This curved spiral geometry naturally transforms the linear reciprocating motion of the slider into continuous rotary motion of the rotor, achieving efficient motion conversion through geometric curvature.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Stability of the object's composition

If the slider continuously contacts the interaction surface of the rotor, then smooth rotary motion is achieved, but friction losses increase reducing overall efficiency

Engineering Contradiction:

Improvemotion continuityVSAvoidfriction energy loss

Core Design Contradiction:

Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The patent incorporates a vibration mechanism that causes the slider to oscillate or vibrate along its path of motion. This vibration reduces the continuous contact pressure between the slider and rotor surface, minimizing friction losses while maintaining the continuous rotary motion output through the dynamic interaction.

Inventive Principle:

Principle #18Mechanical vibration

3Power

If multiple actuating devices are used on a single rotor, then power output is increased, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improverotor power outputVSAvoidmanufacturing complexity

Core Design Contradiction:

PowerVSEase of manufacture

Solution Approach 1:

The invention divides the power generation function into multiple separate actuating devices (such as multiple combustion chambers or actuators) that independently drive a single rotor. Each actuator can be manufactured separately using standardized processes, then assembled onto the rotor, simplifying production while achieving high total power output through cumulative effect.

Inventive Principle:

Principle #1Segmentation
