Solution Overview
Problem
There is a need for improved window frame designs that enhance the sealing between window panes and frames, as well as between adjacent window frames, to better protect against natural elements and simplify the installation process.
Innovation Solution
A window sill frame with an adjustable top portion relative to a base portion, utilizing couplings such as screws, nuts, or hydraulic arms to secure and align windows, along with compression gaskets and heel seal gaskets for effective sealing, and a jacking screw for vertical alignment and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed window frame designs are used, then manufacturing and installation are simpler, but alignment precision and sealing effectiveness deteriorate
Solution Approach 1:
The window frame employs an adjustable top portion that can be moved vertically relative to the base portion through threaded rods and coupling mechanisms. This dynamic structure allows the frame to be adjusted during installation to achieve precise alignment and proper sealing, resolving the contradiction between alignment precision and structural complexity by introducing controlled adjustability only where needed.
Solution Approach 2:
The window frame is divided into separate adjustable components including a base portion, a top portion, and coupling mechanisms with threaded rods. This segmentation allows independent adjustment of the top portion to achieve precise alignment while maintaining the overall structural integrity, addressing the contradiction by making the adjustment mechanism modular and localized.
2Reliability
If adjustable components are added to the window frame, then alignment and sealing are improved, but installation complexity increases
Solution Approach 1:
The adjustable top portion with vertical movement capability enables proper sealing by allowing alignment adjustments during installation. The threaded rod mechanism provides controlled adjustability that improves sealing effectiveness while maintaining reasonable installation ease through a straightforward adjustment process.
Solution Approach 2:
The coupling mechanism allows change in the vertical position parameter of the top portion relative to the base portion. By adjusting this positional parameter, proper sealing alignment is achieved without requiring complex installation procedures, thus improving sealing effectiveness while keeping installation relatively simple.
3Measurement precision
If multiple coupling mechanisms are used for adjustment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism incorporates threaded rods that enable precise vertical adjustment of the top portion. This dynamic adjustment capability provides accurate vertical alignment control through rotational movement of the threaded rods, achieving measurement precision in alignment while maintaining manageable device complexity through a well-established mechanical principle.

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.
