Latch Assembly Guide for Movable Barrier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch assembly installation methods are complex and prone to human error due to the need for precise alignment and aperture formation, which complicates the mounting process and requires additional tools.
Innovation Solution
A guide with marking and alignment indicators simplifies the installation of latch assemblies by facilitating the correct positioning of apertures on a structure, reducing the need for additional tools and minimizing human error through visual and structural alignment features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector is positioned externally of the gate post to allow ease of installation, then the ease of operation is improved, but the reliability deteriorates because the connector is exposed to the external environment
Solution Approach 1:
The connector is nested within the gate post structure by passing through an aperture in the post. The connector is housed inside the gate post rather than being externally mounted, protecting it from environmental exposure while still allowing it to function as part of the latch mechanism.
2Reliability
If a connector passes through an aperture in the gate post, then the reliability is improved by protecting the connector, but the device complexity increases due to alignment requirements
Solution Approach 1:
Alignment features such as guide pins, marking indicators, and reference axes are provided on the latch assembly and gate post to pre-establish the correct positioning before final assembly. These preliminary alignment aids ensure that the connector passes through the aperture correctly without requiring complex adjustment during installation.
3Manufacturing precision
If precise alignment and aperture formation are required for latch installation, then the manufacturing precision is improved, but the ease of manufacture deteriorates due to complex installation processes
Solution Approach 1:
The latch assembly includes self-aligning features such as guide pins, marking indicators, and reference axes that automatically guide the installation process. These features enable the latch to be correctly positioned and aligned without requiring complex external tools or sophisticated installation procedures, making the process both precise and simple.

AI summary
Disclosed is a latch assembly mountable to a structure including a latch, remote actuating unit, and a guide. The guide is adapted to facilitate installation of the latch assembly. The guide is formed separately to the latch and the remote actuating unit. The guide is mounted with one of the latch or remote actuating unit on installation of the assembly on the structure.
