Solution Overview

Problem

Existing tools for installing door frames are either too complex, require multiple tools, or cannot simultaneously square, position, and level the frame effectively, lacking a compact solution for ensuring proper alignment and leveling.

Innovation Solution

A compact apparatus with magnets for positioning, a leveling device for alignment, and an optional laser slot for squaring, along with extendable magnets and spacers, allows for easy and precise installation of door frames by ensuring they are square, positioned correctly, and level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate tools are used for positioning, leveling, and squaring door frames, then each function can be performed with a specialized tool, but the overall device complexity increases and installation time increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidnumber of tools
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple door frame installation tools (level, square, positioning device) into a single integrated apparatus. The rectangular body serves as both the positioning reference and mounting structure for the level and square tools, eliminating the need for multiple separate tools while maintaining all necessary functions for accurate door frame installation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rectangular body of the apparatus serves multiple functions simultaneously: it acts as a positioning reference against the door frame, provides a mounting surface for the level tool, incorporates the square tool for alignment, and can be held by the installer. This multi-functionality reduces the number of separate tools needed while maintaining comprehensive installation capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional separate tools are used for door frame installation, then each tool can be optimized for its specific function, but the installation time and loss of time increase due to handling multiple tools

Engineering Contradiction:
Improveleveling accuracyVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent integrates the level tool, square tool, and positioning functions into a single apparatus that can be held and operated simultaneously. The installer positions the rectangular body against the door frame, activates the level and square functions, and makes adjustments all in one continuous action, eliminating the time required to put down and pick up multiple separate tools during the installation process.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a compact tool is used for door frame installation, then ease of operation and portability improve, but the functionality may be reduced compared to larger specialized tools

Engineering Contradiction:
Improvehandling convenienceVSAvoidinstallation functions
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The rectangular body is designed to provide multiple installation functions within a compact form factor. It serves as a positioning reference, mounting surface for the level, and incorporates the square tool, allowing the installer to perform positioning, leveling, and squaring operations with a single handheld device, maintaining full functionality while improving portability and ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
