Solution Overview

Problem

Conventional RF connectors require time-consuming threading mechanisms for connecting and disconnecting cables to testing equipment, which hampers efficiency, especially during frequent usage.

Innovation Solution

A female type RF connector with a push-on connection system, featuring a conductive sleeve with springs and a middle portion acting as a stop, allowing quick and easy insertion and removal of male type RF connectors, reducing the need for threading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a threaded connection mechanism is used in conventional RF connectors, then the connection provides mechanical strength and reliability, but the connection and disconnection process becomes time-consuming and reduces operational efficiency

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The connector is divided into two functional parts: a push-on connection component for rapid engagement/disengagement and a threaded component for securing the connection. This segmentation allows the operator to quickly connect by pushing (solving the time loss issue) while the threaded portion provides the mechanical reliability when engaged.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The push-on connection mechanism performs the preliminary action of engaging the connector quickly before the threaded mechanism is fully tightened. This preliminary engagement ensures proper alignment and electrical contact are established rapidly, reducing connection time while maintaining reliability through the subsequent threading action.

Inventive Principle:
Principle #10Preliminary action

2Strength

If a threaded fastening mechanism is used, then the connector maintains secure mechanical fastening, but the ease of operation deteriorates due to complex threading requirements

Engineering Contradiction:
Improvemechanical fastening strengthVSAvoidconnection ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The fastening mechanism is segmented into a push-on portion for easy operation and a threaded portion for strength. The push-on action requires minimal effort and no rotational movement, dramatically improving ease of operation, while the threaded section engages to provide the necessary mechanical fastening strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of requiring the user to initiate and complete a threading motion from scratch, the design inverts the approach by allowing push-on engagement first (the easier action), which then enables or facilitates the threading action. This reverses the traditional sequence where threading must be started first.

Inventive Principle:
Principle #13The other way round (Inversion)
