U-Profile Adjustment System for Door Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adjustment of window or door frames in buildings is a tedious and labor-intensive process requiring specialized workers, as it typically allows adjustment in only two dimensions, necessitating manual correction in the third dimension, which can be precarious and costly.
Innovation Solution
A simplified fixing and adjustment system featuring 'U'-shaped profiles attached to both the frame and the enclosure, with a linking mechanism allowing movement in two or three dimensions, incorporating wedges and a safety harness for stability and weather protection, facilitating easier assembly and adjustment by less specialized operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional adjustment methods using wedges and manual leveling are used, then the pre-frame can be adjusted in two dimensions, but the third dimension adjustment becomes precarious and requires highly specialized workers
Solution Approach 1:
The patent introduces an intermediary adjustment device with profiles and link means that mediates between the pre-frame and the enclosure opening. This device provides controlled movement in three dimensions through its mechanical structure, replacing direct manual adjustment with wedges and levels. The intermediary mechanism ensures precise positioning while being easier to operate than traditional methods.
Solution Approach 2:
The adjustment device incorporates dynamic elements including link means with torn areas that allow sliding movement, and a fixing nut that can be positioned at different locations along the link means. This dynamic structure enables continuous adjustment in three dimensions rather than fixed positional adjustments, improving both precision and ease of operation.
2Reliability
If traditional fixing operations with wedges, nails, and cement are used, then the pre-frame can be immobilized to the enclosure opening, but the process requires specialized workers and long performance times resulting in high labor cost
Solution Approach 1:
The adjustment device is pre-assembled with the pre-frame before installation at the enclosure opening. The link means and fixing nut are prepared in advance, allowing the entire adjustment and fixing operation to be completed in one continuous action during installation, rather than requiring multiple separate operations (wedges, nails, cement application, curing time) after installation begins.
Solution Approach 2:
The patent extracts the time-consuming cement application and curing process from the fixing operation. The adjustment device provides mechanical fixing that immobilizes the pre-frame immediately upon installation, eliminating the need for cement or plaster application and the associated waiting time for solidification.
3Manufacturing precision
If adjustment is performed manually with great care to maintain previously adjusted dimensions, then the third dimension can be corrected, but the operation becomes complex and time-consuming
Solution Approach 1:
The adjustment device with its profiles and link means serves multiple functions simultaneously: it enables adjustment in all three dimensions, provides stabilization of the pre-frame, and facilitates final fixing to the enclosure opening. This multi-functional design consolidates what would otherwise require multiple separate tools and operations into a single integrated device, reducing procedural complexity while maintaining dimensional accuracy.

AI summary
Simplified fastening and/or adjustment system for door and/or window frames, made up of - a first profile (4) in a basic "U" shape that is attached to the profile of the window or door enclosure (2) - a second profile (5) also in the shape of a "U" that is attached to the profile of the pre-frame (1) fastened in a single fixing point between both the first profile (4) and second profile (5) with the ability to carry out between both the first profile (4) and second profile (5) a movement in two or three dimensions without invading the polyamide zone of thermal break of the frame improving the thermo-acoustic insulation of the enclosure.
