Solution Overview

Problem

Existing door frame anchoring solutions fail to provide a secure and adjustable method for anchoring metal door frames to floors, particularly in conjunction with wall studs, leading to instability and difficulty in installation.

Innovation Solution

A door frame anchor system comprising a planar flange secured to the door frame and a planar base anchored to the floor, with tabs extending beyond the base's edge to accommodate wall studs, allowing for secure fastening and adjustable positioning to stabilize the door frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing door frame anchoring solutions are used, then installation can be completed, but the door frame lacks stability and security when anchored to floors with wall studs

Engineering Contradiction:

Improvestability of door frame anchoringVSAvoidadaptability to wall studs

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The anchor is divided into distinct functional segments: a flange portion for attachment to the door frame, a base portion for engagement with the floor, and tab portions extending between wall studs. This segmentation allows each portion to perform its specific function independently while contributing to overall stability and adaptability to different wall stud configurations

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The anchor extends in multiple dimensions to accommodate different structural elements: the flange extends vertically to engage the door frame, the base extends horizontally to engage the floor, and the tabs extend laterally to position between wall studs. This multi-dimensional configuration enables the single anchor to provide secure anchoring across multiple spatial dimensions and structural components

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If existing anchoring devices are used, then basic attachment is achieved, but adjustable positioning and ease of installation are compromised

Engineering Contradiction:

Improveease of installationVSAvoidcomplexity of anchor structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Multiple anchoring functions are merged into a single integrated anchor component: the flange provides door frame engagement, the base provides floor engagement, and the tabs provide lateral positioning between studs. This consolidation eliminates the need for multiple separate anchoring components, simplifying installation while maintaining the necessary structural complexity for secure attachment

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The anchor is designed as a multi-functional component that simultaneously performs attachment to the door frame, engagement with the floor, and positioning between wall studs. This universal design allows a single component to replace multiple specialized anchoring devices, improving ease of installation while the inherent structural complexity provides the necessary adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An anchor for securing a metal door frame to a floor comprises a generally planar flange securable in an upright position to an interior surface of the door frame, and a generally planar base extending generally orthogonally with respect to the flange and securable to the floor adjacent the door frame. The base comprises a central portion comprising an inner end adjacent the flange and an opposed outer end defining an outer edge. At least a first tab extends outwardly from the outer end of the central portion and beyond the outer edge.
