Solution Overview

Problem

Existing plug connections are prone to errors and are expensive due to their complex structure, especially when handling multiple conductors, and they can only accommodate a small axis offset, which limits their ability to compensate for tolerances between connected components.

Innovation Solution

A connector design featuring a one-piece conductor with a spring area between its legs, allowing for axial offset compensation through elastic deformation without stress, and an outer conductor with a spring cage for additional support, enabling a compact, weight-reduced, and error-free transmission of high-frequency signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a rigid conductor design is used, then manufacturing precision is improved, but adaptability to axial misalignment deteriorates

Engineering Contradiction:
Improveconductor alignment precisionVSAvoidtolerance to axial offset
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The conductor is designed with a spring section that allows dynamic adjustment during insertion. The spring section can be pre-formed or created by bending, enabling the conductor to adapt its shape to compensate for axial misalignment between connectors while maintaining precise electrical contact.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conductor's geometric parameters are modified by introducing a spring section with specific curvature radius and pitch. This changes the conductor from a rigid straight form to a flexible form that can elastically deform to accommodate varying insertion depths and axial offsets.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a complex multi-part conductor structure is used, then adaptability to misalignment is improved, but device complexity increases

Engineering Contradiction:
Improvetolerance to axial offsetVSAvoidconductor structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spring section is integrated directly into the conductor as a single continuous piece, eliminating the need for separate spring components and multiple assembly steps. The conductor maintains its electrical function while incorporating the spring mechanism, reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conductor incorporates a flexible spring section that can be pre-formed or bent into shape. This flexible portion allows the rigid conductor to adapt to misalignment without requiring complex multi-part structures, achieving simplicity through controlled flexibility.

Inventive Principle:

Solution Approach 1:

The conductor exhibits different mechanical properties in different sections: the contact portions maintain high stiffness for reliable electrical connection, while the spring section has reduced stiffness to enable elastic deformation for compensating axial misalignment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The spring section's elastic deformation characteristics allow the conductor to dynamically adjust to misalignment during insertion. The spring constant is optimized to provide sufficient compliance for compensation while maintaining structural integrity and electrical performance.

Inventive Principle:
Principle #15Dynamics
