Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional multiports use separate receptacles mounted through the housing wall with threaded or bayonet couplings, then connector security and reliability are improved, but the device becomes bulky and consumes significant space

Engineering Contradiction:

Improveconnector securityVSAvoiddevice volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent merges the coupling mechanism and connector retention into a single integrated structure. The coupling mechanism includes a body with an internal cavity that directly receives and secures the connector, eliminating the need for separate receptacles mounted through the housing wall. This integration reduces the overall device volume while maintaining secure connector connection through the unified coupling body design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connector is nested within the internal cavity of the coupling mechanism body. The coupling mechanism contains the connector inside its structure rather than mounting it externally through the housing wall. This nesting approach allows the connector to be housed within the compact coupling body, significantly reducing the space required compared to external receptacle mounting.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If conventional multiports use threaded or bayonet couplings requiring rotation about the longitudinal axis, then connector security is improved, but the device complexity and space requirements increase

Engineering Contradiction:

Improveconnector securityVSAvoidcoupling mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the rotational coupling mechanism (threads or bayonets) from the design and replaces it with a simplified direct-insertion coupling mechanism. The new mechanism uses a coupling body with an opening that directly receives the connector without requiring rotation about the longitudinal axis. This extraction of the complex rotational elements significantly reduces device complexity while maintaining secure connector connection through the simplified direct-insertion design.

Inventive Principle:

Principle #2Taking out (Extraction)

3Volume of moving object

If compact multiport designs are used to reduce space consumption, then device volume is reduced, but connector alignment precision deteriorates

Engineering Contradiction:

Improvedevice volumeVSAvoidconnector alignment precision

Core Design Contradiction:

Volume of moving objectVSManufacturing precision

Solution Approach 1:

The coupling mechanism includes a precisely formed internal cavity and opening that are pre-configured during manufacturing to ensure accurate connector alignment. The body geometry is designed in advance with precise dimensions and orientations that guide the connector into proper alignment upon insertion. This preliminary precision engineering of the coupling cavity ensures that even in compact designs, connector alignment precision is maintained through the pre-configured geometric constraints.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If multiple receptacles are mounted on the housing wall, then port availability is improved, but the device becomes bulky and aesthetically challenging

Engineering Contradiction:

Improveport availabilityVSAvoidhousing surface area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent transitions from mounting receptacles on the external housing surface (2D surface mounting) to integrating coupling mechanisms within the internal volume of the housing (3D internal arrangement). Multiple coupling mechanisms can be arranged in three-dimensional space inside the housing, allowing multiple ports to be available without increasing the external housing surface area. This dimensional transition enables high port availability within a compact footprint by utilizing internal volume rather than external surface area.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
