Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple filtering parts and driving parts are connected by connecting pipes, then the device can perform filtration and pumping functions, but the connection airtightness deteriorates and the structure becomes complicated

Engineering Contradiction:
Improveconnection airtightnessVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the driving pump unit directly within the filtering unit housing, eliminating the need for external connecting pipes between these components. This merging of functions into a single integrated device maintains connection airtightness while simplifying the overall structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The driving pump unit is nested inside the filtering unit housing, with the pump chamber formed within the same housing that contains the filtering chamber. This nesting arrangement eliminates external connections while maintaining functional separation through internal partitions.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If multiple filtering parts and driving parts are connected by connecting pipes, then the device can perform filtration and pumping functions, but the overall volume increases and operation becomes inconvenient

Engineering Contradiction:
Improveoperation convenienceVSAvoiddevice volume
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

By combining the filtering unit and driving pump unit into a single integrated device with a unified housing, the overall volume is reduced compared to separate components connected by pipes. The integrated design also simplifies operation by eliminating multiple connection points and reducing the number of components the operator must manage.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple filtering parts and driving parts are repeatedly used through connecting pipes, then the device can be reused, but bacterial cross-infection risk increases

Engineering Contradiction:
Improveinfection preventionVSAvoidsurgery efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent designs the integrated intracavity gas circulation treatment device as a disposable single-use item. The housing, filtering unit, and driving pump unit are all configured for one-time use and then discarded, eliminating the risk of bacterial cross-infection from repeated use while maintaining high surgery efficiency through ready-to-use sterile devices.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
