Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tools, such as speed squares, struggle to maintain accuracy in wet environments, particularly when cutting non-flat materials like quarter round tile or Schluter trim, as they are difficult to securely engage with wet saws and maintain position.

Innovation Solution

A squaring tool with a right triangle configuration, featuring a hypotenuse slit, second slit, indentation, and pass-through, designed to securely engage with cutting tools like wet saws, providing accurate straight cuts and lines on unusual shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a speed square is used for tile cutting, then perpendicular lines and desired angles can be easily made, but the tool cannot be securely engaged with the wet saw in wet environments

Engineering Contradiction:

Improveease of making perpendicular lines and anglesVSAvoidability to maintain position in wet environment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The tool is divided into distinct functional segments: a speed square component for marking, a clamp component for secure engagement, and a work piece holder for positioning. This segmentation allows each component to perform its specific function optimally while working together as an integrated system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple previously separate tools into one integrated device: the speed square, clamp, and work piece holder are merged into a single unified tool that can be attached to the wet saw, eliminating the need for separate clamps or vices.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If standard cutting tools are used for non-flat materials like quarter round tile, then cutting can be performed, but the materials cannot be held steady or positioned accurately

Engineering Contradiction:

Improveability to cut non-flat materialsVSAvoidaccuracy of cuts on non-flat materials

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The work piece holder features a V-groove with specific angular configurations (e.g., 45-degree angles) designed to match the geometry of quarter round tile and other non-flat materials. This localized geometric adaptation allows the holder to cradle and secure irregular shapes firmly against the saw fence, enabling precise cutting of materials that standard flat tools cannot accommodate.

Inventive Principle:

Principle #3Local quality

3Reliability

If additional clamps or vices are used to secure the speed square, then the tool can be held in position, but the system becomes more complex and less convenient

Engineering Contradiction:

Improvesecure engagement with wet sawVSAvoidnumber of additional components needed

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the clamp functionality directly into the tool body, creating a unified device where the clamp is part of the speed square assembly rather than a separate component. This merging eliminates the need for additional standalone clamps or vices, reducing overall system complexity while maintaining secure engagement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated clamp is designed to perform multiple functions: it secures the speed square to the wet saw, positions the work piece holder, and maintains alignment during cutting. This multi-functionality reduces the need for multiple specialized components, simplifying the overall system.

Inventive Principle:

Principle #6Universality (Multi-functionality)
