Multifunction Straight Edge Guide Angled Handle Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straight edge guides in woodworking are not versatile and require significant setup and time to make cuts at angles other than parallel to the workpiece edge, limiting their application and efficiency.
Innovation Solution
A multifunction straight edge guide with a handle featuring angled perimeter surfaces (90°, 45°, 27.5°, and 13.75°) that can be easily positioned to make cuts at various angles, allowing for quick and precise angle adjustments using a mating edge and locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional straight edge guides are used for angled cuts, then cutting capability is provided, but setup time and complexity increase significantly
Solution Approach 1:
The handle is divided into multiple segments with different angled surfaces (90°, 45°, 27.5°, 13.75°) that can be independently selected and engaged with the straight edge, allowing quick switching between different cutting angles without complex setup procedures
Solution Approach 2:
The handle is designed with multiple angled surfaces that enable the same tool to perform multiple cutting angle functions (90°, 45°, 27.5°, 13.75°), eliminating the need for separate specialized guides for each angle and providing universal angled cut capability
2Adaptability or versatility
If traditional straight edge guides are designed for specific purposes, then functional simplicity is maintained, but versatility is limited
Solution Approach 1:
The handle structure is segmented into distinct angled surfaces that can be independently engaged, allowing the same physical structure to serve multiple cutting angle applications without requiring completely different tools for each function
Solution Approach 2:
Multiple cutting angle capabilities (90°, 45°, 27.5°, 13.75°) are merged into a single handle structure through the inclusion of multiple angled surfaces, expanding application range while containing complexity within one integrated component

AI summary
A multifunction straight edge guide having a handle and a straight edge. The handle has a plurality of perimeter surfaces and the straight edge has a mating edge to mate with one of the perimeter surfaces to interconnect the handle and the straight edge. The handle has three sections, two outer sections and a central support ledge. The outer sections define sidewalls which are generally perpendicular to the support ledge so that the straight edge guide can be used with either the left or right hand by turning the straight edge guide over. Each of the plurality of perimeter surfaces are angled with respect to the sidewalls.
