Solution Overview

Problem

Existing methods for demating multi-pin connectors (MPCs) often result in misalignment, damage to pins or sockets, and lead wire breakage due to manual handling, which lacks a reliable mechanism for stable and even separation.

Innovation Solution

A demating tool with a handle assembly, first and second separating members, and a gripping assembly featuring claws and an elastic member, allowing for parallel movement and radial closure to securely grip and demate connectors without twisting or damaging them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling is used to separate MPC portions, then ease of operation is improved, but reliability deteriorates due to misalignment and damage to pins, sockets, or lead wires

Engineering Contradiction:
Improveease of separationVSAvoiddamage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A demating tool serves as an intermediary device between the user and the MPC portions. The tool includes gripping members that engage with the connectors and separating members that apply controlled separating force, eliminating direct manual handling while preventing misalignment and damage to pins, sockets, and lead wires

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The demating tool is designed to automatically maintain proper alignment between MPC portions during separation through its mechanical structure. The gripping members and separating members are configured to work together in a way that self-corrects alignment issues, allowing the tool to protect the connectors without requiring precise user skill

Inventive Principle:
Principle #25Self-service

2Device complexity

If fixed-size gripping mechanism is used, then device complexity is reduced, but adaptability deteriorates for different connector sizes

Engineering Contradiction:
Improvegripping mechanism simplicityVSAvoidconnector size compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The gripping mechanism incorporates movable and adjustable components that allow the demating tool to adapt to different connector sizes. The gripping members can be positioned at different locations along the connector body, and the elastic member provides flexible engagement force, enabling the same tool to handle various MPC configurations without increasing fundamental device complexity

Inventive Principle:
Principle #15Dynamics

AI summary

A demating device configured to demate an electrical connector assembly having a first connector and a second connector is provided. The demating device may include a first separating member, a second separating member, and a gripping assembly. Actuation of the first separating member and the second separating member towards one another drives the jaws of the gripping assembly together, therein allowing secure gripping of the electrical connector assembly via the demating device for separation of the first and second connectors.
