Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional hoses and piping are used to interconnect separation units, then fluid connections can be established, but the process setup requires extensive space and becomes very cumbersome

Engineering Contradiction:
Improveease of setupVSAvoidspace requirement
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The system divides the process into modular separation units, each with integrated connection elements. This segmentation allows units to be closely positioned without requiring extensive external piping, reducing overall space requirements while maintaining operational flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connection elements are merged directly into the housing of each separation unit. This integration eliminates the need for separate external connection components and reduces the space required for fluid interconnections between units.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If conventional hoses and piping are used for fluid connections, then units can be interconnected, but the setup becomes cumbersome requiring special securing measures

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

Solution Approach 1:

The connection element integrates the fluid passage, mechanical connection, and securing functions into a single component mounted on the housing. This merger eliminates the need for separate securing measures and external piping, reducing setup complexity while ensuring reliable connections.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection element is designed to be self-securing through its integrated structure, automatically providing stable fluid connections without requiring additional external securing components or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If intermediate storage tanks or bags are used between separation steps, then incompatible interfaces can be managed, but the process becomes cumbersome and space-consuming

Engineering Contradiction:
Improveinterface compatibilityVSAvoidprocess complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection element provides universal interfacing capabilities directly integrated into each separation unit, allowing different units with potentially incompatible interfaces to connect directly without intermediate storage. This multi-functional connection element handles both fluid transfer and interface adaptation.

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

Solution Approach 2:

The intermediate storage function is extracted and eliminated by providing direct connection capabilities between separation units. The integrated connection element enables units to be linked directly, removing the need for separate intermediate storage tanks or bags.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If extensive piping and hoses are used for fluid connections, then units can be interconnected, but large dead spaces are created causing backmixing and reduced product yield

Engineering Contradiction:
Improveproduct yieldVSAvoiddead space volume
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The system uses segmented modular units with integrated connections, eliminating the need for extensive external piping. This segmentation reduces the volume of dead spaces where backmixing could occur, thereby improving product yield.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Fluid passages are merged directly into the housing structure of each unit through integrated connection elements. This eliminates separate external piping and reduces dead space volume, preventing backmixing and enhancing product yield.

Inventive Principle:
Principle #5Merging (Combining)
