Problem

Existing connection devices for circulators are inefficient as they can disengage due to incidental forces, leading to potential electrical and mechanical issues.

Innovation Solution

A connection device comprising a connector and socket with guided insertion and locking mechanisms, including ramps and recesses for axial insertion, round guiding surfaces for rotation, and a snap-fit pawl mechanism for irreversible locking, preventing disengagement and ensuring a secure connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple connector and socket design is used, then the device complexity is reduced, but the connection reliability deteriorates due to potential disengagement from incidental forces

Engineering Contradiction:
Improveconnection device structureVSAvoidconnection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The connector incorporates a pawl that can dynamically change its state from engaged to disengaged from the ratchet teeth, allowing the connection mechanism to adapt to applied forces while maintaining reliability. The pawl's ability to move between positions enables the system to handle incidental forces without disengaging the connection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection device is divided into distinct functional segments: insertion means for guiding alignment, locking means with pawl and ratchet teeth for securing the connection, and abutment means for providing end-stop. This segmentation allows each component to perform its specific function efficiently while keeping the overall design manageable.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a secure locking mechanism is implemented, then the connection reliability is improved, but the device complexity increases due to additional locking components

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pawl automatically engages with the ratchet teeth when the connector is inserted and rotated into the locking position, without requiring additional actuators or complex control mechanisms. The spring-loaded pawl self-activates through the rotational motion itself, simplifying the overall system while maintaining secure locking.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The pawl acts as an intermediary element between the connector body and the socket, transferring the rotational motion into a locked position. This intermediary mechanism allows the connection to be secured through a simple rotational movement while providing robust locking through the pawl-ratchet interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If guided insertion means are added, then the ease of operation is improved, but the device complexity increases due to additional guiding components

Engineering Contradiction:
Improveinsertion easeVSAvoidconnection device structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guiding surfaces are integrated directly into the connector body and socket structure, combining the guiding function with the existing structural components. This merging approach provides guidance during insertion without requiring separate guiding elements, thus improving ease of operation while minimizing additional complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector incorporates rounded guiding surfaces that complement the socket's guiding walls, creating a smooth rotational path during insertion. The curved geometry naturally guides the connector into the correct position and orientation, improving ease of operation through intuitive alignment.

Inventive Principle:
Principle #14Spheroidality (Curvature)
