Door and Window Sash Adjustment for Corner Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Misalignment between the sash and frame in doors or windows, particularly at the upper or lower corners on the lock side, leads to gaps that compromise smoke or air tightness, necessitating complex and invasive adjustments or replacements.
Innovation Solution
A door or window design featuring a frame and sash with adjustable devices, including spindle drives and sliding blocks, that allow for easy readjustment of the sash corners to align with the frame, using a central hollow chamber and multiple profile structures for secure and robust fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the frame is subsequently adapted to the sash or glazing is replaced with more rigid glazing, then the misalignment between sash and frame can be corrected, but this involves considerable effort and complex property-specific measures
Solution Approach 1:
The adjustment device is divided into separate modular components: a first adjustment element integrated into the sash frame and a second adjustment element integrated into the frame. This segmentation allows independent adjustment of each component without affecting the other, enabling precise alignment correction through simple relative positioning rather than complex structural modifications.
Solution Approach 2:
The adjustment elements incorporate adjustable features that allow dynamic modification of the sash-frame relationship after installation. The first adjustment element can shift the sash position relative to the frame, while the second adjustment element can shift the frame position relative to the building structure, providing continuous adaptability for alignment correction.
2Manufacturing precision
If tearing open the joint between building structure and building or replacing glazing is performed, then misalignment can be corrected, but this involves considerable effort and invasive measures
Solution Approach 1:
The adjustment elements are pre-integrated into the sash frame and frame structures during manufacturing, with built-in adjustment mechanisms that enable future alignment corrections without requiring invasive construction work. The adjustable features are prepared in advance, allowing simple field adjustments by end users or installers.
Solution Approach 2:
The adjustment elements serve as intermediary components between the sash frame and the frame, and between the frame and the building structure. These intermediaries provide the necessary adjustment capability without requiring direct modification of the building structure or replacement of the glazing, simplifying the correction process.
3Stability of the object's composition
If the sash is made heavier with more rigid glazing, then alignment stability can be improved, but this increases the weight and requires more robust support structures
Solution Approach 1:
Instead of relying on increased weight for stability, the adjustment elements provide dynamic stabilization through adjustable mechanical constraints. The first and second adjustment elements can be configured to provide precise positional control and stability at the desired alignment, maintaining light weight while achieving alignment stability through controlled adjustability rather than mass.
