Window Frame Jacking Screw for Alignment and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved window frame designs that enhance sealing between window panes and frames, as well as between adjacent frames, to better protect against natural elements and simplify the window installation process.
Innovation Solution
A window sill frame with an adjustable top portion and a base portion, secured using couplings such as screws, nuts, or hydraulic arms, which allows for vertical alignment of windows during installation, and incorporates compression gaskets and heel seal gaskets for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed window frame designs are used, then manufacturing is simpler, but alignment precision and sealing effectiveness deteriorate
Solution Approach 1:
The window frame transitions from a fixed structure to a dynamically adjustable one through the jack screw mechanism. The top portion of the frame can be adjusted vertically relative to the base portion, allowing the frame to adapt to installation variations and achieve precise alignment while maintaining structural integrity.
Solution Approach 2:
The frame is divided into distinct segments: a base portion, a top portion, and adjustable intermediate portions. This segmentation allows independent adjustment of each section, enabling precise alignment control without requiring the entire frame to be complex or non-standardized.
2Reliability
If adjustable components are added to the window frame, then alignment and sealing are improved, but device complexity increases
Solution Approach 1:
The jack screw mechanism serves multiple functions simultaneously: it adjusts the vertical position of the frame top, compresses the gasket to ensure sealing, and maintains structural support. This multi-functionality reduces the need for separate adjustment mechanisms and gasket compression devices, thereby limiting the increase in overall complexity.
Solution Approach 2:
The adjustment mechanism and sealing mechanism are merged into a single jack screw assembly. Turning the screw simultaneously adjusts frame alignment and compresses the gasket, combining two critical functions into one component that reduces overall system complexity.
3Object-affected harmful factors
If compression gaskets are used to improve sealing, then protection against natural elements is enhanced, but installation complexity increases
Solution Approach 1:
The gasket is pre-installed in the groove between the base and top portions before the frame is fully assembled. This preliminary placement ensures proper gasket positioning and allows the jack screw mechanism to simply compress it during final assembly, simplifying the overall installation process while ensuring effective sealing.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved sealing against water and wind, facilitates easier window alignment and installation, and maintains structural integrity while ensuring proper sealing between window frames and panes.
Implementation Method 1
turning the jack screw adjusts the top portion of the window sill frame with respect to the base portion of the window sill frame about an axis
Implementation Method 2
compression gasket for engaging a first surface of the window when the window is installed in the window sill frame
Implementation Method 3
heel seal gasket for engaging a second surface of the window when the window is installed in the window sill frame

AI summary
Embodiments described herein may be directed to the functional application and method of use of a jacking screw for adjusting a window frame. In accordance with the present disclosure, adjusting the jacking screw may cause a first portion of the window frame to be lifted or lowered with respect to a second portion of the window frame. In doing so, a desired alignment of a window installed in the window frame may be achieved. This process may eliminate the use of shimming the underlying surface, thereby making it easier to install the window frame on surfaces that are not perfectly level.
