Disposable Carving Blade with Adjustable Eccentricity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carving cutters require multiple tools with specific eccentric values and width radii for varying slot widths, leading to increased costs and imprecise cutting due to mismatched settings, and existing disposable blades necessitate replacing both the blade and arbor to adjust eccentricity, complicating the process.
Innovation Solution
A disposable carving blade with a central hole, asymmetrical cutting rims, and adjustable eccentric value allows for changing the width radius and eccentricity by replacing the blade alone, without altering the cutter arbor, facilitating easier slot width adjustments and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple carving cutters with different eccentric values are used to achieve various slot widths, then cutting precision is improved, but device complexity and cost increase
Solution Approach 1:
The holder is designed with an adjustable eccentric mechanism that allows a single holder to accommodate multiple eccentric values (e=0.01mm to e=0.06mm) by changing the position of the eccentric sleeve. This makes the holder universal and multi-functional, eliminating the need for multiple specialized cutters for different slot widths.
Solution Approach 2:
The eccentric sleeve can be dynamically adjusted to different positions along the cutter arbor axis, changing the eccentric value in use. This dynamic adjustment capability allows the system to adapt to different cutting requirements without requiring multiple static tools.
2Adaptability or versatility
If the eccentric value is increased to accommodate larger width radius, then versatility is improved, but cutting precision deteriorates due to excessive eccentricity
Solution Approach 1:
The system allows precise control of the eccentric parameter by adjusting the eccentric sleeve to specific positions corresponding to different eccentric values (0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm). This enables the user to select the appropriate eccentric parameter for each cutting task, avoiding excessive eccentricity while maintaining versatility.
3Manufacturing precision
If both the disposable blade and cutter arbor are replaced to adjust eccentricity, then cutting precision is maintained, but loss of time and operational complexity increase
Solution Approach 1:
The system separates the adjustable eccentric function into a dedicated holder component, independent of the disposable blade. This segmentation allows the blade to be replaced without affecting the eccentric setting, and the eccentric value can be adjusted by changing the holder configuration rather than replacing the entire arbor assembly.
Solution Approach 2:
The holder acts as an intermediary between the cutter arbor and the disposable blade, providing the eccentric adjustment mechanism. This intermediary allows the arbor to remain fixed while the holder and blade can be independently replaced or adjusted, simplifying the replacement process.
4Manufacturing precision
If the cutting edge is ground to restore sharpness, then cutting precision is improved, but manufacturing complexity and time increase due to precise grinding requirements
Solution Approach 1:
The cutting blade is designed as a disposable component that is replaced when dull rather than being ground and reused. This eliminates the complex and time-consuming grinding process while maintaining cutting precision, as each new blade comes pre-sharpened to the correct specifications.

AI summary
A disposable carving blade contains a central hole defined at a central position thereof, a first central line passing through the central position thereof, a right cutting rim formed on a first peripheral side thereof and a left cutting rim formed on a second peripheral side thereof. The right cutting rim is connected with the left cutting rim to form a V-shaped portion, and the V-shaped portion includes a cutting edge defined on a distal end thereof. An intersection point of the right cutting rim on the first peripheral side of the disposable carving blade and the left cutting rim on the second peripheral side of the disposable carving blade is adjacent to the first central line, and a distance between the intersection point and the first central line is a first eccentric value.
