Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a shunt system is provided exclusively on the fixed plate side, then the shunt function can be implemented between female couplings, but it is not possible to activate the shunt function on the movable plate side during connection and disconnection maneuvers

Engineering Contradiction:

Improveshunt function activation capabilityVSAvoidadditional valves or devices

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shunt function is merged into the male coupling structure itself by integrating a shunt conduit through the movable plate and connecting it to the main body of the male coupling. This eliminates the need for separate valves or additional devices on the fixed plate side, as the male coupling now independently provides shunt capability during connection and disconnection maneuvers.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The male coupling is designed to perform multiple functions: it serves as both the connection interface for hydraulic lines and as the shunt system activator. The integrated shunt conduit allows the same component (male coupling) to enable both fluid connection and shunt operations, eliminating the need for dedicated shunt valves.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the fixed plate is exploited to convey fluid from one female coupling to another, then the shunt function is achieved, but the movable plate side cannot activate shunt function without additional valves

Engineering Contradiction:

Improveshunt function on movable plateVSAvoidadditional valves

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shunt function is segmented and relocated to the movable plate side through the male coupling structure. Instead of relying on the fixed plate's shunt conduit, the system divides the shunt capability into the male coupling assembly, which includes its own shunt conduit opening into the hydraulic line, enabling independent shunt activation on the movable plate side.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If male couplings are inserted in seats of the movable plate, then the coupling structure is established, but the shunt function cannot be activated on the movable plate side

Engineering Contradiction:

Improvecoupling structureVSAvoidshunt function capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The shunt conduit is merged into the existing male coupling structure by opening it directly into the hydraulic line within the main body of the male coupling. This integration allows the same coupling structure that supports male couplings in seats to also activate the shunt function, eliminating the need for separate shunt activation mechanisms.

Inventive Principle:

Principle #5Merging (Combining)
