Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If catalyst is coated inside the heating body to clean tar through chemical reactions, then cleaning function is improved, but device complexity and potential harmful secondary reactions increase

Engineering Contradiction:
Improvecleaning functionVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the cleaning function from complex chemical catalyst systems and implements it through simple microwave heating. The microwave heating device heats the tar directly through dielectric heating, causing it to vaporize and be expelled, eliminating the need for catalyst coating and associated complexity while maintaining effective cleaning functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the chemical reaction-based cleaning system (catalyst) with a physical heating system (microwave). The microwave energy directly heats the tar material, causing phase change from solid/liquid to gas, which is then expelled through the exhaust system, substituting chemical mechanisms with physical thermal processes.

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

2Reliability

If high temperature is used to evaporate tobacco tar, then cleaning effectiveness is improved, but harmful secondary compounds may form

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidharmful secondary compounds
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent controls the heating parameters by adjusting microwave power and heating duration to achieve tar vaporization at controlled temperatures. The system monitors and regulates the heating process to ensure tar is evaporated effectively while preventing excessive temperatures that would cause decomposition and formation of harmful secondary compounds.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If manual cleaning is used for the smoking set, then device structure is simplified, but cleaning completeness and time consumption are problematic

Engineering Contradiction:
Improvedevice structureVSAvoidcleaning completeness
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements self-service cleaning through automatic microwave heating. After use, the system automatically heats the tar residues in the heating chamber, causing them to vaporize and be expelled through the exhaust system. This eliminates the need for manual disassembly and cleaning while achieving complete removal of tar, improving both cleaning completeness and user convenience.

Inventive Principle:
Principle #25Self-service
