Solution Overview

Problem

Existing connector assemblies face challenges in accurately confirming the complete fastening state and position of female and male connectors, as well as the lever, which affects the stability and quality of the electrical connection.

Innovation Solution

A connector assembly with a device for dual position confirmation, featuring a male connector with a position confirmation protrusion and guide pins, a female connector with guide holes, and a lever system that includes a device with a hook and locking bar for ensuring the connectors are securely fastened and the lever is firmly positioned.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a device for lever position assurance is used to confirm the lever position, then the lever position can be recognized, but it is difficult to accurately recognize whether the female and male connectors have been completely fastened to each other

Engineering Contradiction:
Improveposition confirmation accuracyVSAvoidconnector fastening state information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent combines the lever position assurance device and connector position assurance device into a single integrated device for dual position confirmation. This unified device simultaneously confirms both the lever position and the connector fastening state, eliminating the information loss that occurs when separate devices are used. The integration allows one device to provide dual confirmation functions that were previously distributed across multiple components.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If separate devices are used for connector position assurance and lever position assurance, then each position can be confirmed individually, but the device complexity increases

Engineering Contradiction:
Improveposition confirmation capabilityVSAvoidnumber of confirmation devices
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges two separate confirmation devices into one integrated device for dual position confirmation. This single device simultaneously performs both connector position assurance and lever position assurance functions, reducing the overall device complexity while maintaining comprehensive position confirmation capabilities. The integrated design eliminates the need for multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device for dual position confirmation is designed with multi-functionality, serving both as a connector position assurance device and a lever position assurance device. This universal device can confirm multiple positions and states simultaneously, reducing the total number of devices needed while maintaining comprehensive monitoring capabilities for both connector and lever positions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If a simple confirmation mechanism is used, then the device complexity is reduced, but the reliability of position confirmation decreases

Engineering Contradiction:
Improveconfirmation mechanism structureVSAvoidfastening state verification
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The device for dual position confirmation is segmented into distinct functional components: a lever position confirmation portion and a connector position confirmation portion. Each segment independently verifies its specific position, ensuring reliable confirmation of both lever and connector states. This segmentation allows complex verification functions to be divided into manageable, reliable sub-functions that work together systematically.

Inventive Principle:
Principle #1Segmentation

AI summary

A connector assembly has a device for dual position confirmation and is able to accurately show whether female and male connectors have been completely connected to each other at an appropriate position by a lever using the device for dual position confirmation and also to show the connected state and position of the lever. Rotation of the lever draws the connectors together so that, upon complete mating, a protrusion on the male connector causes release of a hook that retains the device whereby the device becomes tilted to indicate complete connection. The device is moved to a position in which it engages and fixes a handle of the lever.
