Solution Overview

Problem

Drilling multiple pocket holes in a workpiece, especially adjacent holes at a predetermined distance, is time-consuming and challenging using a single pocket hole jig.

Innovation Solution

A pocket hole jig assembly comprising interconnected jigs with sliding bodies and angled drill bit apertures, allowing for easy alignment and coupling of multiple jigs to facilitate precise and efficient drilling of multiple holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single pocket hole jig is used to drill multiple adjacent holes, then the device complexity is low, but the productivity is reduced due to time-consuming repositioning

Engineering Contradiction:

Improvedrilling speedVSAvoidjig configuration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The pocket hole jig is divided into separate modular sections that can be independently positioned and then connected. Each section can drill one hole, and multiple sections are assembled together to drill multiple holes in sequence without repositioning the entire jig, thus improving productivity while maintaining manageable complexity through modularity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple pocket hole jig sections are combined into a single integrated assembly that spans across multiple drilling locations. The sections are coupled together with spacing elements that maintain predetermined distances between holes, allowing the operator to drill multiple adjacent holes in one continuous operation rather than repositioning a single jig for each hole.

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If multiple jigs are connected to drill adjacent holes at predetermined distances, then the manufacturing precision is improved, but the ease of operation is reduced due to coupling requirements

Engineering Contradiction:

Improvehole spacing accuracyVSAvoidjig assembly difficulty

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

Spacing elements or coupling mechanisms serve as intermediaries between adjacent jig sections. These intermediaries automatically maintain the predetermined distance between drilling locations when the sections are connected, ensuring manufacturing precision without requiring the operator to perform complex measurements or adjustments during assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The spacing and alignment features are pre-configured into the jig sections during manufacturing. Connection elements, guide rails, or positioning features are built into each section beforehand, so that when sections are assembled, the predetermined hole spacing is automatically achieved without requiring precise manual adjustment by the operator.

Inventive Principle:

AI summary

A pocket hole jig for locating pocket holes in a workpiece includes a base with a base plate and first and second side walls extending along the base plate, and a body disposed between the first and second side walls and slidable along the base in a forward direction and a rearward direction. The body includes a drill bit aperture angled downward toward the base plate. The pocket hole jig also includes a fastener configured to releasably couple the pocket hole jig to an adjacent second pocket hole jig.
