Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If conventional reciprocating engine designs are used, then power output is generated, but vibration occurs and operating efficiency is limited

Engineering Contradiction:
Improvepower outputVSAvoidvibration
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional reciprocating mechanical system with a rotary system where combustion occurs in stationary chambers and thrust is generated through angled exhaust ports. The rotor rotates continuously without reciprocating motion, substituting the piston-crank mechanism with a rotary thrust generation system that eliminates vibration while maintaining power output.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent inverts the conventional approach by having combustion occur in stationary chambers rather than moving pistons, and generating thrust through angled exhaust ports rather than linear piston motion. This inversion of the combustion and thrust generation mechanism eliminates the need for reciprocating components and associated vibration.

Inventive Principle:
Principle #13The other way round (Inversion)

2Power

If conventional engine designs are used, then power output is generated, but operating efficiency is limited due to energy loss

Engineering Contradiction:
Improvepower outputVSAvoidenergy loss
Core Design Contradiction:
PowerVSLoss of energy

Solution Approach 1:

The patent captures the harmful shockwaves and exhaust gas energy that would normally be wasted and redirects them through reflective surfaces back onto the rotor vanes. This converts the harmful exhaust energy into useful thrust, increasing operating efficiency by recovering energy that would otherwise be lost.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent implements a feedback mechanism where reflective surfaces redirect exhaust shockwaves and gas back onto the rotor vanes, creating a feedback loop that recovers energy from the exhaust process and feeds it back to enhance continued rotation, thereby improving overall energy efficiency.

Inventive Principle:
Principle #23Feedback

3Power

If conventional engine designs are used, then power output is generated, but adaptability to different RPM requirements is limited

Engineering Contradiction:
Improvepower outputVSAvoidadaptability to different RPMs
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The patent employs dynamic configuration where the rotor, combustion chambers, and exhaust ports can be adjusted or designed in various configurations to optimize performance at different RPM ranges. This dynamic adaptability allows the engine to be tailored for specific applications requiring peak power at particular rotational speeds.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes by varying the configuration of combustion chambers and exhaust port angles to optimize performance across different RPM ranges. By changing geometric parameters of the combustion system, the engine can be adapted to deliver peak power at specific rotational speeds suitable for different applications.

Inventive Principle:
Principle #35Parameter changes

AI summary

A rotary engine includes a rotor having one or more combustion chambers connected to an exhaust passageway extending radially outward from the combustion chamber to an exhaust port adjacent a peripheral edge of the rotor. The exhaust gas is expelled at an angle to thereby generate cause the rotor to rotate. The housing may include reflective surfaces that reflect shockwaves from the exhaust gas back towards vanes on the rotor to thereby capture additional energy from the exhaust gas. The housing may also include stators that capture additional energy from the exhaust gas and rotate the rotor. An intake port fluidly connected to the combustion chamber is aligned with an opening in the housing as the rotor rotates to thereby allow comprised air to flow into the combustion chamber. As the combustion chamber rotates, it is closed off by a closed portion of the housing, fuel is injected, and ignited, to thereby generate exhaust gases and generate power. The engine does not include reciprocating components, and relatively few moving parts are required.
