Solution Overview

Problem

There is a need for an improved masonry corner jig that provides enhanced repeatability, accuracy, and interchangeability in woodworking and masonry applications, as existing jigs are not adequately tailored for specific tasks.

Innovation Solution

A masonry corner jig with a main elongate body, adjustable grade stakes, L-shaped plates, leg hinges, adjusting rods, and a foot plate, which allows for precise alignment and leveling of concrete slabs and walls, enabling efficient and accurate construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a masonry corner jig is designed with adjustable components and multiple attachment points, then alignment precision and adaptability improve, but device complexity increases

Engineering Contradiction:
Improvealignment precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The masonry corner jig is divided into multiple independent components including the main body, adjustable legs, grade stakes, and attachment mechanisms. Each component can be independently adjusted or replaced, allowing precise alignment while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The jig incorporates dynamically adjustable elements such as legs with multiple positioning holes, adjustable grade stakes, and removable attachments. These dynamic features enable the device to adapt to various alignment requirements and terrain conditions, improving measurement precision without requiring a completely different device for each scenario.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the masonry corner jig includes multiple adjustment mechanisms and components, then adaptability improves, but ease of operation deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adjustment mechanisms are pre-configured with standardized positioning holes and pre-attached components that can be quickly engaged or disengaged. Grade stakes come pre-marked with reference points, and legs have predetermined adjustment positions, eliminating the need for complex calculations or measurements during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The design incorporates self-aligning features and intuitive attachment mechanisms that guide the operator through the setup process. The jig's structure naturally guides components into correct positions, and quick-release mechanisms allow operators to make adjustments without specialized tools or complex procedures.

Inventive Principle:
Principle #25Self-service
