Guided Tool Position Calibration for Dust-Obscured Cutting Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visual guides drawn on materials can be difficult for users to follow manually, and determining the position of a tool on these materials is challenging, especially when dust is generated during tasks like cutting wood, which can obscure markers and make it hard to detect the tool's position accurately.
Innovation Solution
The system includes a rig or frame with sensors and cameras that can determine the tool's position on a material by using location markers, force sensors to detect changes in force when the tool touches the surface, and a mechanism to direct and extract dust, allowing for accurate movement and positioning of the tool along a desired path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual guides are drawn on material, then positioning guidance is provided, but the guides become difficult to follow manually and position determination becomes challenging
Solution Approach 1:
The patent replaces manual visual tracking with an automated sensor system. Sensors mounted on the tool automatically detect position markers on the material surface, eliminating the need for manual following of visual guides. The system uses optical or electromagnetic sensors to detect marker positions and automatically calculates tool location coordinates, substituting human visual-motor coordination with automated detection mechanisms.
Solution Approach 2:
The patent introduces position markers as intermediaries between the tool and the material surface. These markers serve as detectable reference points that facilitate automated position determination. The markers act as a mediator that the sensor system can reliably detect to establish precise tool positioning without requiring manual interpretation of visual guides.
2Productivity
If dust is generated during cutting, then material processing is performed, but dust obscures markers and makes tool position detection difficult
Solution Approach 1:
The patent extracts or removes dust from the detection field using vacuum systems or airflow generators. By actively removing dust particles from the area between the sensor and the material surface, the system maintains clear optical paths for marker detection. This extraction of the harmful dust element preserves detection accuracy while allowing continuous cutting operations to proceed.
Solution Approach 2:
The patent converts the dust generation issue into a manageable parameter by using the dust presence as feedback. The sensor system detects both markers and dust particles, and the control system compensates for dust interference by filtering signals or adjusting detection parameters. This approach transforms the harmful dust into a detectable condition that can be managed through signal processing.
3Measurement precision
If automated positioning system is implemented, then tool position accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the positioning system into independent modular components: position markers on the material, sensors on the tool for detection, and a control system for processing. This segmentation allows each component to be optimized independently and simplifies the overall system architecture. The markers provide reference information, the sensors collect data, and the control system processes information, creating a distributed system that reduces central complexity.

Implementation Method 1
The system, method or apparatus can determine changes in the force exerted by the tip of the tool (e.g., a cutting bit) in order to determine when the tip of the cutting tool is touching or pressing against the surface of the material
Implementation Method 2
a fan of the tool may direct the dust towards the cavity
Implementation Method 3
