Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If separate components are used to supply samples and absorption liquids to the combuster and absorber, then the system is reliable and functional, but the device structure becomes complex and bulky

Engineering Contradiction:
Improvenumber of componentsVSAvoidsupply function reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines separate supply components into a single integrated supplier that supplies both samples and absorption liquids. This merging reduces the number of components and simplifies the device structure while maintaining the functional reliability of supplying both materials to their respective processing units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The supplier is designed as a universal component that performs multiple functions: supplying samples to the combuster, supplying absorption liquids to the absorber, and potentially performing cleaning functions. This multi-functionality reduces the overall component count while ensuring reliable operation across different supply needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Volume of moving object

If multiple separate components are used for sample and absorption liquid supply, then each component can be optimized for its specific function, but the overall device size increases

Engineering Contradiction:
Improvedevice sizeVSAvoidcomponent optimization
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

By merging the sample supply and absorption liquid supply into a single supplier component, the overall device volume is reduced. The integrated design eliminates the need for separate supply mechanisms, thereby compacting the device while still allowing internal optimization of the supply pathways and mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal supplier design allows for optimized internal structure that handles multiple materials (samples and absorption liquids) through a single integrated system, reducing device size while maintaining manufacturing feasibility through standardized multi-functional component design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If a simplified supplier structure is used, then the device becomes compact and cost-effective, but the precision of sample and absorption liquid supply may be compromised

Engineering Contradiction:
Improveprocess efficiencyVSAvoidsupply precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The integrated supplier maintains high supply precision by incorporating precise control mechanisms within the unified structure. The merging of functions does not compromise precision because the internal design includes controlled pathways and dosing mechanisms for both samples and absorption liquids, ensuring accurate delivery while improving overall process efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal supplier achieves both compactness and precision through multi-functional design that incorporates precise metering and control systems for different materials. This allows the single component to maintain manufacturing precision while enhancing productivity through streamlined operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
