Infinity Joint Jig Drill Guide Angled Wood Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for joining wood, such as dovetail and pocket hole joints, are either difficult to form, require expensive tooling, or are not suitable for angled connections, and lack aesthetic appeal and ease of use.
Innovation Solution
The development of an infinity jig and method that uses a base and upright with drill guides to form infinity holes, allowing for the insertion of an infinity plug to pull workpieces together, creating a strong, aesthetically pleasing joint that can be used at various angles and thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dovetail joints are used to join two pieces of wood, then a strong and durable connection is achieved, but the joint is difficult to form and requires complicated and expensive tooling and machinery
Solution Approach 1:
The dovetail joint is segmented into two separate operations: drilling rectangular holes through a jig and inserting pre-cut dovetail plugs. This divides the complex single-step cutting process into simpler, more manageable steps that can be performed with basic hand tools rather than expensive machinery.
Solution Approach 2:
A drilling jig serves as an intermediary device that guides the drill bit to create precisely positioned rectangular holes. The jig acts as a mediator between the simple drilling action and the complex dovetail joint formation, enabling accurate joint creation without sophisticated tooling.
2Ease of operation
If pocket hole joints are used to join two pieces of wood, then the joining process is simplified and ease of use is improved, but the joint is not suitable for angled connections and has limited adaptability
Solution Approach 1:
The drilling jig is designed with adjustable components that allow the user to change drilling angles and positions dynamically. This enables the same basic tool to adapt to different joint configurations including angled connections, eliminating the limitation of fixed-angle pocket hole jigs.
Solution Approach 2:
The drilling jig is designed as a universal tool that can create various types of holes at different angles and positions on workpieces. This multi-functional capability allows it to handle perpendicular joints, angled joints, and different workpiece thicknesses, making it more versatile than specialized pocket hole jigs.
3Device complexity
If traditional drilling methods are used without a jig, then device complexity is reduced, but manufacturing precision and alignment accuracy deteriorate
Solution Approach 1:
The drilling jig incorporates self-aligning features such as clamps and positioning mechanisms that automatically guide the workpiece into the correct position. This self-service capability ensures precise hole alignment without requiring complex adjustment procedures or highly skilled operation.
Solution Approach 2:
The jig replaces manual alignment and positioning with mechanical guidance features built into the device structure. Drill guides, stop blocks, and clamping mechanisms provide automatic mechanical alignment, substituting for imprecise manual positioning and ensuring consistent precision across multiple joints.

AI summary
An infinity jig, infinity plug and a method of forming an infinity joint is presented. The infinity jig has a base with a work surface and an upright with a work surface connected to the base at an approximate perpendicular alignment. The upright includes a plurality of drill guides that are positioned such that a portion of a drill bit inserted into the drill guide extends below the work surface of the base. An infinity hole is formed by using a drill bit having a stop collar to drill partially into a workpiece with a portion of the drill bit exiting a connecting surface of the work piece. To form an infinity joint, two workpieces having infinity holes therein are aligned with one another and an infinity plug is inserted in the aligned infinity holes. The infinity plug pulls the two workpieces together providing a tight and aesthetically pleasing joint.
