Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools require complicated and time-consuming processes to establish proper orientation, often necessitating manual adjustment with external sensors like spirit levels, which can be cumbersome and skill-dependent.
Innovation Solution
Integration of sensors, such as accelerometers, within the tool bar of a cutting tool to estimate its rotational orientation relative to the axis, eliminating the need for external sensors and simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external sensors like spirit levels are used to check cutting tool orientation, then orientation measurement capability is provided, but device complexity and ease of operation deteriorate due to manual placement and adjustment requirements
Solution Approach 1:
The patent combines the cutting tool with integrated sensors (accelerometers, gyroscopes, or magnetometers) directly mounted on the tool bar, merging the measurement function into the tool itself. This eliminates the need for separate external spirit levels and manual placement procedures, thereby reducing device complexity while maintaining orientation measurement capability.
Solution Approach 2:
The cutting tool becomes self-sufficient for orientation measurement through integrated sensors that automatically provide orientation data without requiring external assistance. The tool serves its own measurement needs, eliminating the need for operators to manually place and read external spirit levels, thus improving ease of operation.
2Measurement precision
If external sensors like spirit levels are used to check cutting tool orientation, then orientation measurement capability is provided, but loss of time increases due to manual adjustment and reading procedures
Solution Approach 1:
The patent replaces mechanical spirit levels with electronic sensors (accelerometers, gyroscopes, or magnetometers) that provide digital orientation data. This substitution eliminates manual placement, adjustment, and reading procedures, significantly reducing the time required for orientation establishment while maintaining or improving measurement precision.
Solution Approach 2:
The integrated sensors provide real-time orientation feedback to the operator through displays or interfaces on the cutting tool itself. This immediate feedback eliminates the time delay associated with manual spirit level reading and adjustment, allowing operators to quickly determine and correct orientation as needed.
3Measurement precision
If manual adjustment with external spirit levels is used, then orientation checking is possible, but ease of operation worsens due to skill-dependent procedures
Solution Approach 1:
The patent replaces skill-dependent manual spirit level procedures with electronic sensors and digital displays that automatically calculate and present orientation information. This substitution removes the need for operator skill in manually placing and reading spirit levels, making the orientation process easier and more accessible to operators of all skill levels.
