Shim Jack Frame Assembly for Door Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frame assembly technologies face challenges in securely bracing door frames against framing members, particularly in ensuring precise adjustment and secure fastening, which can lead to misalignment and instability.
Innovation Solution
A frame assembly incorporating a shim jack with an adjustment screw and feet featuring surface features for gripping, allowing for adjustable connection to a jamb leg, enabling precise bracing and secure fastening within a door opening by moving the shim jack in the shim space between the frame and framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional bracing methods are used to secure door frames, then the door frame can be installed, but misalignment and instability occur due to inability to make precise adjustments
Solution Approach 1:
The shim jack incorporates an adjustment mechanism that allows the bracing element to be dynamically positioned at various heights and angles during installation. This dynamic adjustability enables precise alignment of the door frame with the rough opening while maintaining structural stability through secure fastening options.
Solution Approach 2:
The shim jack allows changing of geometric parameters (height, angle, position) to achieve proper door frame alignment. By adjusting these parameters, the system can accommodate variations in rough opening dimensions and ensure precise installation without compromising frame stability.
2Manufacturing precision
If adjustable bracing mechanisms are added to improve alignment, then alignment precision improves, but device complexity increases
Solution Approach 1:
The shim jack is divided into functional segments: a bracing element for positioning, an adjustment mechanism for height/angle control, and a fastening system for securing. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple and manageable.
Solution Approach 2:
The shim jack serves multiple functions: it provides structural bracing, enables precise alignment through adjustment, and ensures secure fastening. This multi-functionality consolidates what would otherwise require multiple separate tools or components into a single integrated device, reducing overall system complexity.
3Reliability
If secure fastening is implemented to ensure stability, then frame stability improves, but ease of operation decreases due to complex adjustment and fastening procedures
Solution Approach 1:
The adjustment mechanism is designed to be self-contained and intuitive, allowing the installer to make adjustments without requiring additional tools or complex procedures. The integrated design enables the operator to both adjust and secure the bracing element using the same device, simplifying the installation process while maintaining stability.

AI summary
Aspects of the disclosure relate to a frame assembly, such as a door frame assembly for hanging a door. A frame assembly can include a longitudinal adjustment mechanism and a shim jack for connecting to the adjustment mechanism. The shim jack can include a longitudinal body with a first leg and a second leg extending from a base of the longitudinal body. The frame assembly can also include a frame with a jamb leg for adjustably connecting to the adjustment mechanism. The jamb leg can define a port for receiving the shim jack, and the adjustment mechanism may be operable to move the base of the shim jack with respect to the jamb leg to brace the frame assembly within an opening, e.g., by moving the first leg and the second leg against a framing member that defines the opening.
