Multi-Joining Jig With Interchangeable Templates for Precise Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing woodworking methods for connecting workpieces using connectors like dovetails, box joints, mortise and tenon, dowels, biscuits, and dominos require individual structures, which are expensive and occupy significant workshop space.
Innovation Solution
A multi-joining system comprising a workpiece joining jig with a template holding jig and a workpiece support that allows for precise orientation and positioning of templates and workpieces, enabling various connections such as dovetails, mortise and tenon, dowels, dominos, and butterflies, while reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual structures are used for each connection type (dovetails, box joints, mortise and tenon, dowels, biscuits, dominos), then each connection can be formed with high precision, but the workshop space required and cost increase significantly
Solution Approach 1:
The patent implements a universal jig system with interchangeable templates that can form multiple connection types (dovetails, box joints, mortise and tenon, dowels, biscuits, dominos) using a single base structure. The template holder accepts different templates for various joint types, eliminating the need for separate dedicated jigs for each connection method, thus reducing workshop space while maintaining precision.
Solution Approach 2:
The system divides the connection-forming capability into separate interchangeable templates that can be attached to a single template holder. Each template is designed for a specific connection type, allowing the user to swap templates as needed rather than having multiple complete jig structures, thereby reducing space requirements while preserving manufacturing precision for each joint type.

AI summary
A template holding jig for holding a template for use with a router for routing a workpiece is provided. The holding jig may also be part of a workpiece joining jig that includes a plurality of templates. The template holding jig includes a template support, a workpiece support and a template guide. The template support defines a template support plane. The workpiece support defines a workpiece support plane extending perpendicular to the template support plane. The template guide defines at least one abutment preventing motion of a template located on the template support parallel to a first axis being parallel to the workpiece support plane and parallel to the template support plane. The at least one abutment permits motion of the template parallel to a second axis being orthogonal to the workpiece support plane and perpendicular to the first axis and parallel to the template support plane.
