Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the socket main body and socket base portion are separately provided to enable radial movement, then radial positional deviations can be corrected, but the external shape becomes larger and miniaturization is hampered

Engineering Contradiction:

Improvecorrection of radial positional deviationVSAvoidexternal shape size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges the socket main body and socket base portion into a single integrated structure. The housing includes both the base portion and the movable portion as one piece, eliminating the need for separate components while maintaining the floating mechanism's ability to correct radial positional deviations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a floating mechanism where the housing movable portion can move radially relative to the housing base portion. This dynamic structure allows the socket to self-adjust and correct radial positional deviations between plug and socket during connection, while the integrated design prevents increase in overall size.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If coil spring or disc spring is used for biasing the socket main body, then axial or radial movement is enabled, but the parts count increases and manufacturing complexity increases

Engineering Contradiction:

Improvefloating movement capabilityVSAvoidparts count

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing movable portion itself serves as the biasing element through its elastic deformation capability. The movable portion is designed with elastic properties that enable it to deflect and provide the necessary biasing force for the floating mechanism, eliminating the need for separate spring components.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent changes the material or structural parameters of the housing movable portion to give it elastic properties. By modifying the physical characteristics of the movable portion (such as material selection or structural design), it gains the ability to deform elastically and provide biasing force without requiring additional spring parts.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the socket allows movement in only radial directions, then radial misalignment is corrected, but axial gaps occur degrading shielding characteristic

Engineering Contradiction:

Improvecorrection of radial misalignmentVSAvoidshielding characteristic

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The housing movable portion is designed to perform multiple functions simultaneously: it enables radial movement for correcting radial misalignment, maintains axial contact for shielding, and provides elastic biasing force. This multi-functional design ensures both radial alignment correction and axial gap prevention.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The floating mechanism allows the housing movable portion to move dynamically in response to connection conditions. When plug and socket connect, the movable portion can deflect radially to correct misalignment while maintaining contact in the axial direction, ensuring continuous shielding without gaps.

Inventive Principle:

Principle #15Dynamics

AI summary

In a coaxial connector with a floating mechanism, a housing of a socket includes a housing base portion and a housing movable portion which can move radially over a plug-side end face of the housing base portion with a socket-side center contact. A top side of a plug-side shell is fitted onto the housing movable portion. A socket-side shell integrally includes shell contact plate portions which are exposed from the plug-side end face of the housing base portion. An end of the plug-side shell is configured to come into contact with the shell contact plate portions.
