Adjustable Mate Assist Lever for Multi-Width Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mate assist devices for electrical connectors are limited to specific connector housing widths, leading to high production and logistics costs due to the need for differently sized devices.
Innovation Solution
A U-shaped mate assist device with adjustable width, featuring symmetrical arms with form-locking elements such as snap-fit hooks and protrusions, allowing for versatile connection to various connector housings through multiple interlocking positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a U-shaped lever is made rigid to withstand forces during activation, then strength is improved, but flexibility to be securely attached to the connector deteriorates
Solution Approach 1:
The lever is divided into two separate arms that can be attached to the connector housing independently. Each arm can be secured separately, allowing the connector to accommodate both rigid structural requirements and flexible attachment needs. The segmentation allows each part to be optimized independently for its specific function.
2Reliability
If mate assist devices are designed for specific connector housing widths, then reliability is improved, but adaptability to various connector widths deteriorates
Solution Approach 1:
The mate assist device with two adjustable arms can accommodate multiple connector housing widths by adjusting the spacing between arms. This universal design allows a single device type to serve multiple functions across different connector sizes, eliminating the need for multiple specialized devices while maintaining reliable operation for each specific connector width.
Solution Approach 2:
The lever arms are designed to be adjustable in position relative to each other, allowing the device to dynamically adapt to different connector widths. This adjustability transforms a static, width-specific device into a dynamic, multi-width compatible tool that maintains reliability across various applications.
3Adaptability or versatility
If multiple differently sized mate assist devices are produced for various connector widths, then adaptability is improved, but manufacturing complexity and logistics costs worsen
Solution Approach 1:
By designing a single mate assist device type with adjustable arm spacing, the invention consolidates multiple width-specific devices into one universal product. This reduces manufacturing complexity by standardizing production around a single design, simplifies inventory management, and lowers logistics costs while maintaining the ability to accommodate various connector widths through the adjustable mechanism.

AI summary
The invention relates to a connector assembly that includes a housing and a U-shaped mate assist device. This device comprises two arms that can be connected. Each arm has one or more locking elements designed to engage with matching locking elements on the other arm, creating e.g. a form-locked connection. Additionally, these locking elements are positioned on an interlocking portion of each arm in such a way that they can interlock in at least two different positions. This feature allows the width of the U-shaped mate assist device to be adjusted as needed.
