Solution Overview

Problem

Conventional connectors are prone to breakage when subjected to non-axial tension, which is common in environments like aircraft cabins where headsets or cables can be accidentally pulled or caught, leading to damage.

Innovation Solution

The connector apparatus incorporates magnetic means and spring contacts with a specific alignment contour to ensure secure connection and prevent damage by allowing power supply only when the plug is correctly connected, utilizing a magnetic connection system with conductor contact regions arranged in layers for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connectors with pins and sockets are used, then electrical connection is established, but the connector is prone to breakage when subjected to non-axial tension

Engineering Contradiction:
Improveconnector reliabilityVSAvoidresistance to non-axial tension
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent replaces the conventional mechanical pin-and-socket connection system with a magnetic field-based connection system. Magnets embedded in both the plug and socket create magnetic attraction forces that hold the connector components together, eliminating the need for rigid mechanical interlocking pins and sockets that are susceptible to breakage under non-axial tension.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental connection parameter from mechanical interlocking to magnetic field interaction. By utilizing magnetic field strength as the binding parameter instead of mechanical fit, the connector achieves greater flexibility and resistance to non-axial forces while maintaining reliable electrical connection.

Inventive Principle:
Principle #35Parameter changes

2Strength

If magnets are used to hold connector components together, then resistance to non-axial tension is improved, but the magnetic field may interfere with other components

Engineering Contradiction:
Improveresistance to non-axial tensionVSAvoidmagnetic field interference
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the magnetic field generation function into separate magnet components that are embedded within the plug and socket housings. This allows the magnetic field to be contained and directed primarily between the connector components, reducing stray magnetic field interference with other electronic components while maintaining the beneficial magnetic holding force.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces magnetic shielding materials or non-magnetic structural elements as intermediaries between the magnets and other electronic components. These intermediaries redirect or contain the magnetic field lines, preventing harmful magnetic interference with sensitive electronics while allowing the magnetic connection to function effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If contact regions are exposed for connection, then ease of connection is improved, but the connector is more vulnerable to damage

Engineering Contradiction:
Improveease of connectionVSAvoidprotection against damage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent nests the electrical contact regions within recesses or cavities in the plug and socket structures. The contacts are positioned inside these nested spaces, which are accessible for connection but provide protective enclosure. This nested arrangement allows easy insertion and connection while shielding the vulnerable contact regions from external damage and contamination.

Inventive Principle:
Principle #7Nested doll (Nesting)
