Solution Overview

Problem

High-power RF connector assemblies with low intermodulation require rigid connections, making quick connection/disconnection difficult and unsuitable for modular applications, especially in remote radio head technology where rapid integration of antenna tower modules is necessary.

Innovation Solution

A blind mating and floating RF connector assembly with a slotted configuration and guiding means, allowing the male and female connectors to float radially and axially, enabling quick connection/disconnection without precise alignment, using a floating unit and elastic members for radial and axial movement, and beveled guide portions for coaxial alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid connection is used between male and female connectors to ensure reliable contact and low PIM, then connection reliability is improved, but connection speed deteriorates due to requirement for precise alignment

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The connector employs a floating unit that can dynamically adjust its position relative to the fixed mount unit, allowing the connectors to self-align during insertion rather than requiring precise pre-alignment. This dynamic adjustment mechanism maintains reliable contact while enabling faster connection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guiding means acts as an intermediary mechanism between the male and female connectors, providing alignment guidance during the connection process. This intermediary structure enables quick blind mating while ensuring proper alignment for reliable electrical contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If precise axial alignment is required for rigid connection, then connection reliability is improved, but ease of operation deteriorates due to difficulty in quick blind mating

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of connection operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The floating unit provides dynamic positioning capability, allowing the connector to automatically adjust to slight misalignments during insertion. This eliminates the need for precise manual alignment while maintaining reliable connection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guiding means performs preliminary alignment action during the insertion process, automatically orienting the connectors correctly before final engagement. This preliminary alignment action simplifies the operation while ensuring reliable connection.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If high torque is applied to ensure reliable contact in high-power RF connector assembly, then connection reliability is improved, but device complexity increases due to need for special tools and sufficient operating space

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

Solution Approach 1:

The floating unit enables the connector to self-adjust and self-align during assembly, eliminating the need for special alignment tools and reducing the complexity of the assembly process. The connector essentially services its own alignment requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The dynamic floating mechanism allows the connector to automatically achieve proper contact pressure and alignment without requiring high assembly torque or special tools, thereby reducing assembly complexity while maintaining connection reliability.

Inventive Principle:
Principle #15Dynamics
