Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screw connection with bushings is used to connect the cooling pipe to the housing, then the connection is secure and reliable, but the manufacturing process becomes more complex and costs increase

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

Solution Approach 1:

The male connector integrates the connection function directly into the cooling pipe component itself, merging what were previously separate elements (pipe and connector) into a single integrated part. This eliminates the need for separate bushings and screw connections while maintaining secure attachment through the elastic pin mechanism that engages with the housing bore.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts and eliminates the unnecessary intermediate components (bushings and screws) from the connection system. By removing these extraneous elements and replacing them with a direct elastic pin engagement mechanism integrated into the male connector, the design simplifies the manufacturing process while preserving connection reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If screws and bushings are used for connection, then the connection is stable, but additional manufacturing effort and costs are required

Engineering Contradiction:
Improveconnection stabilityVSAvoidmanufacturing ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The male connector combines the cooling pipe and connector functions into a single integrated component with elastomeric pins directly formed as part of the pipe structure. This merging eliminates the need for separate bushings and screw fasteners, reducing the number of parts to manufacture while maintaining stable connection through the elastic pin-housing bore engagement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastomeric pins provide self-aligning and self-securing functionality during insertion into the housing bore. The elastic deformation of the pins during insertion and their subsequent recovery creates an automatic locking mechanism that ensures stable connection without requiring separate fastening operations or additional components.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If an elastic pin is added to the male connector, then the connection becomes easier and cheaper, but the device structure becomes more complex

Engineering Contradiction:
Improvemanufacturing easeVSAvoidconnector structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The elastomeric pins are integrated directly into the male connector body as a unified structure, combining the connector housing and fastening elements into a single component. This integration adds minimal structural complexity compared to separate screw and bushing assemblies, while significantly simplifying the manufacturing process by reducing the number of parts and assembly steps.

Inventive Principle:
Principle #5Merging (Combining)
