Movable Cleat Edge Bolt Wedging Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching edge fittings to openings, such as doors and windows, are time-consuming, require precise machining, and need specialized skills, making them costly and prone to assembly errors, especially in large-scale industrialization.
Innovation Solution
An edge fitting system that uses a movable cleat to securely attach a mounting plate to the opening edge without the need for pre-drilling or precise machining, utilizing a wedging mechanism between the cleat and the opening's stops to ensure a secure and stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw fixing is used to attach edge fitting to opening edge, then secure attachment is achieved, but installation time increases and requires precise machining
Solution Approach 1:
The cleat is designed to be movable during installation, transitioning from a retracted position (allowing insertion) to an extended position (providing secure attachment). This dynamic element eliminates the need for precise pre-drilling and screw fastening, reducing installation time while maintaining attachment security through the wedging action between the cleat and stop.
2Manufacturing precision
If screw fixing with pre-drilled holes is used, then precise alignment is achieved, but machining complexity and cost increase
Solution Approach 1:
The mounting plate is designed with pre-formed attachment features (the movable cleat mechanism) that eliminate the need for field drilling and alignment. The cleat is pre-positioned on the mounting plate and works with the stop on the opening edge to provide self-aligning attachment, removing complex machining operations from the installation process.
3Reliability
If traditional screw attachment is used, then firm fixation is achieved, but operator skill requirements increase
Solution Approach 1:
The movable cleat mechanism is designed to be self-actuating during installation. The installer simply moves the cleat to the extended position, and the wedging action between the cleat and stop automatically provides firm fixation. This eliminates the need for skilled operators to perform precise drilling, alignment, and screw fastening operations.
4Manufacturing precision
If multiple machining operations are performed on mounting plate and opening edge, then attachment precision is improved, but manufacturing cost increases
Solution Approach 1:
The attachment function is segmented into two independent elements: the movable cleat on the mounting plate and the stop on the opening edge. This segmentation allows each element to be manufactured separately with simple geometry, avoiding the need for complex coordinated machining of multiple holes and threads across different components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for rapid, error-free, and cost-effective attachment of edge fittings to openings by a single person without specialized skills, reducing installation time and labor costs while ensuring a secure fit.
Implementation Method 1
adapted to be able to be moved by at least one position, called the free position, in which it can be inserted between said front walls of the opening, to a position, called the blocked position, in which it is housed and wedged between said mounting plate and said stops so as to ensure that said mounting plate is pressed against the edge of the opening

AI summary
The edge fitting has a fixation unit for fixing a mounting plate (11) on an edge (4) of an opening. The fixation unit has a stop (13) that is movable for fixing the plate on the edge for being displaced from free position towards locked position. The stop is inserted between front walls (2, 3) of the opening in the free position. The stop is housed and wedged between the mounting plate and stopper (7) in a manner to ensure placing of the plate against the edge, which prohibits displacement of the plate with respect to the edge. An independent claim is also included for sliding opening such as door or window.
