Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional internal continuous combustion engines are designed with separate compressor and motor components, then the engine can maintain continuous combustion operation, but the device complexity and space requirements increase

Engineering Contradiction:
Improvecontinuous combustion operationVSAvoidseparate compressor and motor components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the compressor and pneumatic motor into a single unified assembly where the compressor is directly coupled to the motor shaft. This merging of components maintains the continuous combustion operation while significantly reducing device complexity and eliminating the need for separate drive mechanisms, thereby reducing the overall number of parts and simplifying the engine architecture

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the engine uses a large displacement compressor to ensure sufficient compressed air supply, then the combustion process is maintained, but the engine size and weight increase

Engineering Contradiction:
Improvecompressed air supplyVSAvoidengine size and weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent employs a high-speed rotating compressor design that achieves sufficient compressed air supply through increased rotational speed rather than increased displacement size. This parameter change allows the compressor to deliver the required air flow rate while maintaining a compact size and reduced weight, as the high rotational velocity compensates for the smaller compressor displacement

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the engine operates at high rotational speeds to increase power output, then productivity improves, but mechanical stress and wear increase

Engineering Contradiction:
Improvepower outputVSAvoidmechanical stress and wear
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent utilizes pneumatic cushioning where compressed air is introduced into the combustion chamber to provide a cushioning effect during operation. This pneumatic mechanism reduces mechanical impact and stress on moving parts during high-speed rotation, thereby mitigating wear and mechanical stress while allowing the engine to operate at high rotational speeds for increased power output

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

An integrated rotary expansible chamber device comprises a compressor and a pneumatic motor housed within a single engine block. The pneumatic motor includes a cylindrical casing having a pressurized gas inlet, an exhaust outlet, and an off-center output shaft with a rotor mounted on it. The rotor have spring-loaded radially sliding vanes. The vanes sealed with the casing wall by pivoted shoes. The pneumatic motor powers the compressor, supplying compressed air to a combustion chamber, which produces pressurized combustion gases to drive the pneumatic motor. The device incorporates a recess for gradual (extended) exhaust gas release, air and fuel storage tanks for rapid starting without a starter motor. In another embodiment, the pneumatic motor consists of cylindrical casing with centrally meshed radial vanes mounted on coaxial shafts, driven by inverted crank slider mechanism in the adjacent drive box. This embodiment feature labyrinth sealing for oil-free operation and versatile functionality.
