Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional multi-component mating connector design is used, then connection reliability is improved, but manufacturing complexity increases

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

Solution Approach 1:

The patent combines multiple traditional connector components (body, sealing elements, locking mechanisms) into a single integrated sheet metal formed part. This merging reduces the number of separate components that need to be manufactured and assembled, thereby reducing manufacturing complexity while maintaining the functional reliability of the connection through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sheet metal formed part is designed to perform multiple functions simultaneously: providing structural support, creating sealing surfaces, enabling locking mechanisms, and facilitating connection to various components. This multi-functionality reduces the need for separate specialized components, simplifying manufacturing while maintaining connection reliability.

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

2Ease of manufacture

If a sheet metal formed part is used for the connector body, then ease of manufacture is improved, but structural strength may be reduced

Engineering Contradiction:
Improveease of manufactureVSAvoidstructural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent utilizes sheet metal forming to create a connector body that leverages the inherent strength-to-weight ratio of metal sheets. Through strategic forming and shaping, the thin sheet metal structure achieves sufficient structural strength for connector applications while maintaining ease of manufacture through standard sheet metal forming processes.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the physical parameters of the sheet metal through forming processes, creating varied thicknesses, reinforcements, and geometric configurations that optimize both structural strength and manufacturability. The sheet metal is transformed from a simple flat sheet into a complex three-dimensional structure with enhanced mechanical properties.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If a deep-drawn single-piece connector body is used, then manufacturing time is reduced, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemanufacturing timeVSAvoidmanufacturing precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The deep-drawing process is designed as a preliminary forming operation that creates the basic connector body shape in a single step. Subsequent operations build upon this pre-formed structure, allowing for efficient sequential manufacturing while maintaining precision through the controlled deformation of the sheet metal during each stage.

Inventive Principle:
Principle #10Preliminary action
