Solution Overview

Problem

Visual guides for tools on materials are difficult to follow manually, especially for complex paths, and mechanical guides are cumbersome to set up and lack flexibility.

Innovation Solution

A computer-implemented method and system that uses sensors, cameras, and positioning logic to accurately guide tools on materials by generating custom designs, determining tool positions, and automatically correcting deviations from a design path using servomechanisms, stepper motors, and eccentric mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visual guides are drawn on material using measuring devices, then the tool can be guided along a path, but the guides are difficult for users to follow manually

Engineering Contradiction:
Improveease of following visual guidesVSAvoidprecision of tool positioning
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces manual visual guidance with an automated optical guidance system. A camera captures images of the material surface and design features, while a processor automatically calculates tool positions and provides real-time guidance, eliminating the need for users to manually follow drawn visual guides.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a digital copy of the material surface and design by capturing images with a camera. This digital representation is then processed to generate precise tool path guidance, allowing the tool to follow the design path accurately without requiring manual interpretation of visual guides.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If mechanical guides such as railings or fences are put in place to assist the user in guiding the tool, then movement can be constrained, but the guides take time to set up and may not support complex paths

Engineering Contradiction:
Improveability to support complex pathsVSAvoidsetup time for mechanical guides
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces physical mechanical guides with a digital guidance system. The camera and processor capture and calculate tool paths for complex designs, providing flexibility and adaptability without requiring physical setup of railings or fences.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The guidance system is dynamic and adaptable, allowing the tool to follow complex paths by processing real-time images and calculating appropriate tool positions. The system can accommodate various design complexities without requiring different physical guide structures.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If hand tools are used to facilitate guiding a tool, then movement in one or more directions can be minimized, but the tools lack flexibility for complex paths

Engineering Contradiction:
Improveflexibility for complex pathsVSAvoidprecision of tool movement control
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent replaces manual hand tools with an automated guidance system that uses camera imaging and processor calculations to precisely control tool movement. This provides both the precision needed for accurate path following and the flexibility to handle complex designs.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system continuously captures images of the material surface and design features, processes this information to determine current tool position, and provides real-time feedback for adjusting tool movement. This closed-loop control ensures both precision and flexibility in following complex paths.

Inventive Principle:
Principle #23Feedback
