Modular Router Guide Jig with Adjustable Backset and Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing router guide jigs are either not configurable for both doors and frames or are overly complicated and cumbersome, failing to efficiently route different sized mortises for various door thicknesses.
Innovation Solution
A modular router guide jig with a frame assembly featuring adjustable backset members, clamp members, and a divider block that allows for configuration changes to accommodate different door thicknesses by adjusting the receiving opening's dimensions and clamping force, enabling the formation of mortises for hinges and latch plates on doors and frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If router guide jigs are made configurable for different door and frame thicknesses, then adaptability is improved, but device complexity increases and becomes cumbersome for users
Solution Approach 1:
The router guide jig is divided into separate modular components including a frame assembly with legs, a support member with receiving opening, adjustable backset members, and clamp members. Each component can be independently positioned and secured, allowing the jig to be configured for different door and frame thicknesses without requiring a completely different tool for each application.
Solution Approach 2:
The jig incorporates adjustable backset members that can be repositioned along the legs and clamp members that can be adjusted to different positions. This dynamic adjustability allows the same jig to accommodate varying door and frame thicknesses while maintaining simplicity through straightforward adjustment mechanisms rather than complex reconfiguration.
2Adaptability or versatility
If the receiving opening is made larger to accommodate thicker doors, then adaptability is improved, but manufacturing precision for smaller mortises decreases
Solution Approach 1:
A divider block is introduced as an intermediary component that can be positioned within the receiving opening to effectively reduce its size. The divider block creates a smaller routing space within the larger receiving opening, allowing precise routing of smaller mortises for thinner doors while maintaining the ability to route larger mortises for thicker doors when the divider is removed or repositioned.

AI summary
A router guide jig includes a frame assembly that includes a first leg, a second leg, and a support member. The support member has an opening extending through the support member positioned at least in part offset from the first leg. The receiving opening defines a first axis. The router guide jig includes at least one backset member carried by the first leg having a first abutment surface facing away from the first leg. The at least one backset member is positionable in at least a first position and in a second position relative to the first leg. In the first position, the first abutment surface is spaced a first distance from the first leg. In a second position, the first abutment surface is spaced a second distance from the first leg. The router guide jig includes at least one clamp member carried by the second leg having a second abutment surface facing away from the second leg. The at least one clamp member is adjustable relative to the second leg to adjust a clamping force provided by the at least one clamp member.
