Parallel Square Alignment Tool for Repeatable Cutting Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning tools and fixtures require multiple steps and secondary tools to achieve precise parallelism and squareness between edges of a work piece, leading to inefficiencies and potential dimensional variations during cutting or routing operations.
Innovation Solution
A parallel and square alignment tool system that utilizes complementary reference surfaces for direct and precise alignment of a work component, such as a track saw rail, allowing for simultaneous perpendicular and parallel alignment without the need for additional marking or tools, using a combination of square and parallel alignment portions with a movable arm assembly for flipstop functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If T-slots are used to connect alignment tools to work components, then the connection can be established, but the precision and sturdiness of the connection deteriorates
Solution Approach 1:
The alignment tool is divided into separate modular components (square alignment portion and parallel alignment portion) that can be independently positioned and connected to the work component, allowing each segment to be precisely aligned independently while maintaining overall connection stability
Solution Approach 2:
Complementary reference surfaces act as intermediary elements between the alignment tool and work component, providing a precise mating interface that ensures accurate alignment without relying on T-slot connections alone
2Manufacturing precision
If manual marking and multiple steps are used to achieve parallelism, then alignment can be attempted, but the time and complexity increase
Solution Approach 1:
The square alignment portion and parallel alignment portion are combined into a single integrated tool that simultaneously provides both alignment functions, eliminating the need for separate marking operations and multiple alignment steps
Solution Approach 2:
The alignment tool pre-establishes the correct geometric relationships (square and parallel) through its built-in reference surfaces, so that the work component can be directly aligned without preliminary manual marking or measurement steps
3Productivity
If a single alignment tool is used for both square and parallel alignment, then efficiency improves, but the device complexity increases
Solution Approach 1:
The unified alignment tool is segmented into distinct functional portions (square alignment portion with first reference surface, and parallel alignment portion with second reference surface) that can be independently configured, allowing complex alignment tasks to be performed efficiently while maintaining modular simplicity
Solution Approach 2:
The alignment tool is designed with multi-functionality, where the same tool structure provides both square alignment (perpendicular to first edge) and parallel alignment (parallel to second edge) capabilities through its complementary reference surfaces, eliminating the need for multiple separate tools

AI summary
An alignment tool is disclosed for connection to a work component and for use in aligning the work component with a work piece to establish a repeatable set up for cutting or routing of the work piece, and wherein the alignment tool provides for parallel and square alignment of the work component relative to first and second edges of the work piece that are perpendicular to each other. Use of the parallel and square alignment tool aligns the work component for an operation parallel to the second edge of the work piece and the operation may be conveniently repeated on further work pieces without need to measure and mark the work pieces. Optional use of first and second parallel and square alignment tools along opposed second and third edges of a work piece that are perpendicular to a first edge provides for greater accuracy for operations having a greater length.
