Pocket Hole Jig With Integrated Clamp and Pivoting Drill Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pocket hole jigs require the use of two hands to tighten and lock objects while also aligning the drill guide, making them cumbersome and inefficient for single-handed operation, especially when working with existing furniture or cabinets.
Innovation Solution
A self-aligning pocket hole jig that allows single-handed operation by using a moveable clamp head and actuator, which locks the clamp head against the object and rotates the drill guide to a suitable angle based on the object's dimensions, eliminating the need for two-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pocket hole jig is used with separate clamp and drill guide alignment mechanisms, then the clamping and alignment functions are provided, but two hands are required for operation making it cumbersome and inefficient
Solution Approach 1:
The patent combines the clamp head and drill guide into a single integrated assembly where the drill guide is rotatably coupled to the clamp head. This merging allows both clamping and alignment functions to be controlled by a single actuator, enabling single-handed operation while maintaining both functions.
Solution Approach 2:
The actuator serves multiple functions: it actuates the clamp head to clamp the workpiece and simultaneously rotates the drill guide to the correct angle. This multi-functionality eliminates the need for separate mechanisms and hands for each operation.
2Productivity
If a pocket hole jig requires separate locking mechanisms for clamping and alignment, then secure clamping is achieved, but the device becomes more complex and time-consuming to operate
Solution Approach 1:
The patent merges the clamping and alignment locking functions into a single actuator mechanism. When the actuator is moved to its actuated position, it simultaneously clamps the workpiece and locks the drill guide at the correct angle, eliminating the need for separate locking operations.
Solution Approach 2:
The drill guide is pre-configured with alignment features that automatically engage with the clamp head when the actuator is activated. This preliminary setup ensures that the correct angle is locked in place as part of the single clamping action, without requiring additional alignment steps.
3Adaptability or versatility
If a pocket hole jig uses fixed drill guide angle, then alignment is simplified, but adaptability to different workpiece dimensions is reduced
Solution Approach 1:
The patent makes the drill guide rotatable relative to the clamp head, allowing it to dynamically adjust to different workpiece dimensions. The drill guide can be rotated to different angles and locked in place, providing adaptability while maintaining a relatively simple mechanism through the use of rotational movement and locking features.

AI summary
A pocket hole jig includes a body; an actuator operatively coupled to the body; a clamp head movable relative to the body to selectively secure an object in a clamping region of the pocket hole jig; and a drill guide defining a guide axis for a drill bit, wherein the actuator is moveable between an open position and a closed position, wherein movement of the actuator from an open position to a closed position tightens the clamp head against the object and locks the clamp head in a tightened state against the object, and wherein movement of the actuator from an open position to a closed position pivots the drill guide and locks the drill guide with the guide axis at a specified alignment with respect to the clamping region.
