Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spreading tools for hollow metal door frames are not adjustable, cannot secure themselves at multiple heights, fail to correct imperfections and twisting during installation, and lack the ability to pull and push the frame to the desired width, leading to improper alignment and installation challenges.
Innovation Solution
An adjustable door frame spreading tool with bifurcated ends and a collapsing/expanding middle section, featuring magnets for secure attachment and adjustable width, allowing for proper leveling and alignment of the door frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional non-adjustable spreader is used, then the tool structure is simple, but it cannot accommodate various frame sizes and dimensions
Solution Approach 1:
The spreader incorporates an adjustable middle section with telescoping components that allow the tool length to be dynamically changed. This enables the same tool to accommodate different door frame sizes by extending or retracting the middle section, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The spreader is divided into multiple segments including a first end, an adjustable middle section, and a second end. This segmentation allows independent adjustment of each component, enabling the tool to adapt to various frame dimensions while maintaining manageable structural complexity through modular design.
2Reliability
If a traditional spreader is used, then the tool is simple to manufacture, but it cannot secure itself to the frame at multiple heights
Solution Approach 1:
The spreader incorporates magnets at its ends that automatically attract to the metal door frame, providing self-securing capability without requiring manual fastening. This eliminates the need for complex manual attachment mechanisms while ensuring reliable securement at the required heights.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems (screws, clips, or manual clamps) with magnetic attraction forces. This substitution simplifies the attachment mechanism while maintaining or improving reliability, as the magnets automatically secure the tool to the metal frame without complex mechanical components.
3Manufacturing precision
If a traditional spreader is used, then the tool lacks additional functional features, but it cannot correct imperfections and twisting during installation
Solution Approach 1:
The spreader's adjustable middle section allows installers to pre-set the correct spacing and alignment before final installation. By adjusting the tool to match the desired door frame dimensions in advance, any twisting or misalignment issues can be prevented or corrected during the positioning phase, improving manufacturing precision without requiring complex correction mechanisms.
4Force
If a traditional non-adjustable spreader is used, then the installation process is simple, but it lacks the ability to pull and push the door frame to the desired width
Solution Approach 1:
The adjustable middle section of the spreader can be extended or retracted to apply controlled pushing or pulling forces to the door frame. This dynamic adjustment capability allows the installer to exert the necessary force to move the frame to the correct width and position, while the adjustable nature maintains operational simplicity by using a straightforward telescoping mechanism.
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 accurate alignment and expedites the installation process by securely attaching to the door frame, correcting misalignments and twisting issues, and accommodating various frame sizes and dimensions.
Implementation Method 1
The square ends having a magnet for attachment to the door frame rabbet on either side of the door stop. The magnets present in the square ends will secure the tool to the door frame. These magnets have adequate strength to support and secure the tool to the door frame and pull the door frame to the proper width and position

AI summary
An adjustable door frame spreading tool to aid in the alignment and mounting of a hollow metal door frame. The tool includes and first end and second end connected to a collapsing/expanding middle section. The first end and the second end are bifurcated with an adjustable width of the bifurcation. Each end of the bifurcation being square and level and including a magnet for attachment to the door frame. The tool will spread the door frame and pull the door frame into alignment for attachment to an opening.
