Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If chemical absorption method using amine solution is used to capture carbon dioxide, then carbon dioxide capture effectiveness is improved, but equipment scale and structural complexity increase making it unsuitable for household use

Engineering Contradiction:

Improvecarbon dioxide capture effectivenessVSAvoidequipment scale and structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention divides the carbon dioxide capture system into separate functional components: an absorber containing the amine-based absorbent and filters positioned between the absorber and ambient air. This segmentation allows the system to be compact and suitable for household use while maintaining effective carbon dioxide capture through the amine solution

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention nests the absorber containing the amine-based absorbent within a housing structure that includes integrated filters. This nested configuration reduces overall equipment scale and simplifies the structural arrangement, making the carbon dioxide capture system suitable for household environments while preserving capture effectiveness

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If strong alkaline amine is used for carbon dioxide absorption, then carbon dioxide capture capability is improved, but health risks and safety concerns increase

Engineering Contradiction:

Improvecarbon dioxide capture capabilityVSAvoidhealth damage from strong alkaline amine

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention introduces filters as an intermediary component positioned between the absorber containing the strong alkaline amine and the ambient air. This filter acts as a mediator that allows carbon dioxide to pass through for absorption while preventing the strong alkaline amine from escaping into the living space, thus maintaining capture capability while eliminating health risks

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts the harmful strong alkaline amine from direct contact with the living environment by confining it within the absorber unit and using filters to prevent its release. This separation allows the system to maintain high carbon dioxide capture capability through the use of effective amine solutions while protecting occupants from health damage

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If amine-based absorbent is used without filtration, then carbon dioxide absorption efficiency is improved, but amine leakage and portability issues arise

Engineering Contradiction:

Improvecarbon dioxide absorption efficiencyVSAvoidamine leakage prevention and portability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The invention introduces filters as an intermediary component that mediates between the amine-based absorbent and the external environment. The filter allows carbon dioxide to reach the absorbent for efficient absorption while simultaneously preventing amine leakage, thus resolving the contradiction between absorption efficiency and reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention applies different properties to different parts of the system: the absorber contains the amine-based absorbent with high reactivity for efficient carbon dioxide absorption, while the filters provide selective permeability to allow gas passage but prevent liquid amine leakage. This local differentiation of properties achieves both high absorption efficiency and reliable leak prevention

Inventive Principle:

Principle #3Local quality
