Adjustable Table Saw Sled for Repeatable Kumiko Joint Notches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DIY methods for creating Kumiko lattice grids are limited by fixed joint registrations, restricting the types, styles, and sizes of grids that can be made, and lack the ability to cut successive identical joint notches with adjustable spacing.
Innovation Solution
A table saw sled with adjustable registration keys and movable frameworks that allow for cutting identical joint notches at consistent intervals, featuring a substrate with guide blocks and adjustable registration keys to facilitate the formation of Kumiko lattice grids, accommodating various table saws and enabling both rectangular and angled joint cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed registration keys are used in DIY table saw sleds, then the structure is simple and easy to manufacture, but the adaptability is limited because users can only make one type of grid with fixed joint spacing
Solution Approach 1:
The registration keys are made movable along the miter track rather than fixed, allowing users to adjust the spacing between joint notches. The registration keys can be repositioned to different locations on the miter track, enabling the same sled to accommodate various grid sizes and patterns. This dynamic adjustment capability resolves the contradiction by providing versatility without requiring multiple separate sleds.
Solution Approach 2:
The table saw sled is designed to perform multiple functions: it can create different grid patterns, accommodate various workpiece widths, and adjust joint spacing by repositioning the registration keys. This multi-functional design allows a single device to replace multiple specialized tools, improving adaptability while maintaining reasonable structural simplicity.
2Adaptability or versatility
If the runner is fixed relative to the miter track, then the structure is simple, but the adaptability is reduced because the sled cannot accommodate various table saw configurations
Solution Approach 1:
The runner is designed with adjustable positioning relative to the miter track, allowing it to be moved to different locations. This dynamic adjustment enables the sled to accommodate various table saw configurations and workpiece widths. The runner can be repositioned along the miter track to maintain proper alignment with the blade and miter track, resolving the contradiction between simplicity and adaptability.
3Adaptability or versatility
If angled guide planes are embedded in grooves along the upper surface, then the structure is simple and stable, but the adaptability is limited because the guide planes cannot be repositioned for different cutting angles
Solution Approach 1:
The guide planes are made movable rather than fixed in grooves, allowing them to be repositioned along the miter track. This enables the sled to accommodate different cutting angles and workpiece orientations. The guide planes can be adjusted to maintain proper alignment for various joint types and grid patterns, providing adaptability while keeping the overall structure relatively simple.

AI summary
A table saw sled that facilitates cutting successive identical joint notches with identical spacing along an elongated strip of material, wherein the spacing is selectively adjustable through reconfigurable elements of the table saw sled. The table saw sled mounts a table saw by providing movable frameworks and reference points via registration keys that can both retain the strip of material at a desired distance from and orientation to relative to the saw blade. The selectively movable registration keys enable the cutting of identical joint notches at identical intervals along the length of the strip of material, thereby facilitating the formation of lattice grids for Kumiko work.
