Pocket Hole Drilling Tool With Integrated Clamp and Angle Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power tool jigs for forming pocket holes in woodworkpieces are time-consuming, require multiple components, and involve complex method steps, often necessitating the repositioning and reclamping of the workpiece after each hole is drilled, which can be inefficient and labor-intensive.
Innovation Solution
A portable power tool apparatus with a drill bit, motor, and clamping mechanism that allows for guided and repeatable hole formation, featuring a movable part that advances the drill bit at an adjustable angle, reducing the number of steps required and eliminating the need for a separate drill guide, with a user-operable trigger and adjustment mechanism for secure clamping and precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional jig apparatus is used to form pocket holes, then guided and repeatable hole formation is achieved, but the apparatus is time-consuming to fit and requires multiple components
Solution Approach 1:
The patent combines the drill guide, clamping mechanism, and depth control into a single integrated power tool apparatus. The housing integrates the guide structure that defines the acute angle, while the clamping jaws and depth stop are built-in components rather than separate accessories. This merging eliminates the need for multiple separate components and reduces setup complexity.
Solution Approach 2:
The power tool apparatus serves multiple functions: it guides the drill bit at the correct acute angle, clamps the workpiece securely during drilling, controls the drilling depth, and provides repeatable positioning. This multi-functionality replaces the need for separate drill guides, clamps, and depth control devices, reducing the overall complexity while maintaining precision.
2Manufacturing precision
If conventional jig apparatus is used, then hole formation guidance is provided, but the drilling procedure requires multiple method steps and workpiece repositioning
Solution Approach 1:
The apparatus allows continuous drilling operations without requiring the workpiece to be removed, repositioned, or reclamped between holes. The workpiece remains clamped in the same position, and the operator can drill multiple holes sequentially by simply repositioning the tool along the workpiece edge. This eliminates the interruptive steps of conventional jig usage and maintains continuous productive action.
Solution Approach 2:
The apparatus automatically maintains the correct drilling angle and depth control through its integrated guide structure and depth stop mechanism. The system self-regulates the drilling parameters without requiring manual intervention or adjustment between holes, allowing the operator to simply move the tool to the next drilling location while the apparatus maintains precision automatically.
3Manufacturing precision
If conventional jig and drill combination is used, then pocket holes can be formed, but safety is reduced due to complex operation steps
Solution Approach 1:
By integrating the guide structure, clamping mechanism, and depth control into a single powered unit, the apparatus eliminates the need for multiple separate components that must be assembled and adjusted. This reduction in components decreases the opportunity for assembly errors and simplifies the operation, making the process safer and more reliable.
Solution Approach 2:
The patent replaces manual drill-and-jig operations with a powered tool that automatically provides rotational force and controlled advancement. The motor-driven mechanism reduces manual manipulation steps, minimizing the risk of operator error and improving safety while maintaining the precision of pocket hole formation.

AI summary
The current invention provides apparatus and a method for use with a drill bit to form a hole in a workpiece, said apparatus including a clamping means to clamp a workpiece in which the hole is to be formed in position with the apparatus, a drill bit holder assembly and drive means for rotating the drill bit and moving the same into the workpiece so as to drill the hole at a required angle and depth into the workpiece. Typically the depth of the hole is set in relation to the thickness of the workpiece which is clamped in position at that time and the apparatus includes a first part which is held by a first hand of the user and movable by the user with respect to a second part which is held by a second hand of the user and the relative movement is translated into movement of the drill bit holder to move the rotating drill bit into the workpiece.
