Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional flushing device with base element and pipe connection element is used, then the flushing solution can be received and transferred, but the equipment complexity increases and the transfer process becomes less efficient

Engineering Contradiction:
Improvetransfer efficiencyVSAvoidequipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the tubular core element and the foil hose into a single integrated fluid transfer device. The core element serves both as structural support and as part of the fluid conduction path, while the foil hose is sealed to the core element to form a continuous fluid pathway. This merging eliminates the need for separate base elements and pipe connection elements, reducing equipment complexity while maintaining transfer efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tubular core element performs multiple functions: it provides structural support for the foil hose, serves as a conduit for the flushing solution, and works with the sealing element to prevent leakage. The foil hose similarly serves both as the flexible connection to the pipeline and as part of the sealed fluid pathway. This multi-functionality reduces the number of components needed while maintaining effective flushing solution transfer.

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

2Reliability

If the flushing solution is transferred without proper sealing, then the transfer process is simpler, but uncontrolled leakage occurs causing environmental contamination and health hazards

Engineering Contradiction:
Improvesealing effectivenessVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a foil hose as a flexible thin-film structure that can be sealed to the tubular core element. This foil hose provides the necessary sealing function to prevent leakage of the flushing solution while maintaining a relatively simple device structure. The flexibility of the foil allows it to conform to the core element and create an effective seal without requiring complex sealing mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing element acts as an intermediary component between the tubular core element and the foil hose, creating a sealed connection that prevents leakage. This intermediary sealing mechanism ensures reliable containment of the flushing solution while adding minimal structural complexity to the overall device. The sealing element mediates the connection between the two main components, providing the necessary barrier function.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If gaseous components of the flushing solution are released, then the transfer process is less complex, but health risks and staining occur

Engineering Contradiction:
Improvehealth risks and environmental contaminationVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The foil hose, as a flexible thin-film structure, provides containment for the flushing solution and its gaseous components. The foil material creates a barrier that prevents the release of harmful gases and prevents staining by containing the flushing solution throughout the transfer process. This simple yet effective barrier function addresses the harmful factors without requiring complex containment systems.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The foil hose appears to be designed as a disposable or single-use component that provides effective containment during the flushing operation. This approach allows for reliable prevention of gas release and staining using a simple, inexpensive structure that can be discarded after use, avoiding the need for complex, reusable containment systems with multiple sealing mechanisms.

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