Spacer Clip Stop Lug for Window Seal Gap Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window systems experience misalignment and deformation of seals due to relative deviations between the frame and sash, leading to premature wear, water accumulation, and visual deformity, particularly when aluminum frames or shells are attached, causing the seal to be subjected to torsion and compression.
Innovation Solution
An adjustment aid with a stop lug that projects beyond the frame's inner visible surface to create a defined gap and ensure proper alignment, using snap-fit or clamping fastening, and can be adapted to different thicknesses of aluminum shells or frames, optionally made of plastic and with rubberized tips to minimize noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If aluminum frames or shells are attached to reduce the gap, then the sealing gap is reduced, but the seal is subjected to torsion and compression leading to deformation
Solution Approach 1:
The adjustment aid is installed on the frame before the final assembly, establishing a predetermined reference position that guides the sash frame alignment. This preliminary positioning action prevents misalignment and subsequent seal deformation during closing operation.
Solution Approach 2:
The adjustment aid serves as an intermediary element between the frame and sash frame, providing a physical reference surface that mediates the alignment relationship. This intermediary component ensures proper spacing and positioning without directly involving the seal in the alignment process.
2Adaptability or versatility
If the sash position is adjusted to accommodate tolerances, then alignment flexibility is improved, but the seal adheres to the frame and experiences harmful stresses
Solution Approach 1:
The adjustment aid preemptively counteracts the harmful effect of misalignment by establishing a fixed reference position. This preliminary anti-action prevents the sash from adhering to the frame and eliminates the torsional and compressive stresses that would otherwise damage the seal.
3Manufacturing precision
If the gap is reduced with aluminum frames, then manufacturing precision is improved, but water accumulation occurs at indentations
Solution Approach 1:
The adjustment aid is installed in advance to establish the correct gap dimension before final assembly. This preliminary positioning ensures consistent spacing that prevents water accumulation while maintaining the precision benefits of aluminum frames.
4Reliability
If the seal is compressed to ensure tight sealing, then sealing effectiveness is improved, but the seal deforms and becomes clogged more quickly
Solution Approach 1:
The adjustment aid establishes the correct sash position before the seal is subjected to compression. This preliminary alignment ensures that the seal receives only the intended compressive force without additional torsional stress, maintaining both sealing effectiveness and extending service life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures a consistent seal gap and prevents seal deformation, reducing noise and water accumulation, maintaining a visually appealing and functional seal over time.
Implementation Method 1
the means for attaching the adjustment aid are a snap-fit or clamping fastening, which allows for a defined attachment of the adjustment aid to the frame
Implementation Method 2
The tip of the stop nose can optionally be insulated, preferably rubberized, so that when used as intended, it makes no noise or only a quiet, pleasant noise when it comes into contact with the sash frame
