Adjustable Door Frame With Integral Shim Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional installation of door frames in rough openings is labor-intensive and time-consuming, often resulting in incorrect positioning and operation issues due to the use of shims and anchor screws.
Innovation Solution
A door frame assembly with integral shim screws that are adjustable and embedded within hollow rectangular tubes, allowing for secure and precise positioning of the frame by exerting compression force against the rough opening surfaces, facilitating faster and more accurate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shims and anchor screws are used to secure the door frame, then the door frame can be installed in the rough opening, but the installation process becomes labor-intensive and time-consuming
Solution Approach 1:
The shim and anchor screw functions are merged into a single integrated component - the shim screw. This combined component simultaneously provides shimming (positioning) and anchoring (securing) functions, eliminating the need for separate shims and anchor screws, thereby reducing installation steps and time while maintaining positioning accuracy
Solution Approach 2:
The shim screw serves multiple functions: it acts as both a positioning shim and an anchoring fastener. This multi-functional component can be adjusted to provide precise positioning while simultaneously securing the door frame to the rough opening, replacing multiple traditional components with a single universal solution
2Reliability
If traditional shims and anchor screws are used to secure the door frame, then the door frame can be installed in the rough opening, but the installation process becomes complex and prone to errors
Solution Approach 1:
By combining the shim and anchor screw into a single integrated component, the number of parts and assembly steps is reduced. This simplifies the installation process, making it less complex and more straightforward, while maintaining the reliability of door frame positioning through the integrated design
Solution Approach 2:
The shim screw is designed to be self-aligning and self-adjusting during installation. The threaded structure allows for easy adjustment and secure engagement with the rough opening without requiring complex alignment procedures or multiple components, making the installation process more foolproof and less prone to errors

AI summary
A door frame assembly includes integral shim screws in the vertical jambs that facilitate installation of the assembly into a rough opening or doorway. The vertical frame jambs have one or more holes therethrough. Shim screws are positioned in those apertures and are adjustably extendable outwardly therefrom to engage a rough opening to assist in fixing the frame in that opening.
