Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If high temperature combustion gas is used to heat the processing object from outside the processing cylinder, then the processing object can be carbonized, but material attachment occurs and steam flow is disrupted

Engineering Contradiction:

Improvecarbonization temperatureVSAvoidmaterial attachment

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces superheated steam as an intermediary heating medium between the combustion gas and the processing object. The steam circulates inside the processing cylinder, transferring heat to the material without direct contact between the combustion gas and material, thereby preventing attachment while maintaining effective carbonization temperatures

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct thermal contact heating with indirect steam heating. Instead of allowing combustion gas to directly contact the processing object, the system uses a steam circulation mechanism where steam is generated, injected into the processing cylinder, condenses on the material providing heat, and is then reheated and recirculated

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Temperature

If high temperature combustion gas is used from outside the processing cylinder, then carbonization can be achieved, but steam flow optimization is lost

Solution Approach 1:

The patent implements a continuous steam circulation system where steam is constantly generated, injected into the processing cylinder, condenses on the material, and is reheated for recirculation. This continuous cycle ensures uninterrupted heat transfer and maintains optimal carbonization conditions throughout the treatment process
