Disposable Carving Blade with Adjustable Eccentric Value
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 components, and existing disposable blades necessitate matching holders, complicating adjustments and increasing expenses.
Innovation Solution
A disposable carving blade with a parallelogram shape and asymmetric cutting rims, allowing the eccentric value to be changed by replacing the blade without altering the cutter arbor, enabling flexible slot width adjustments and reducing production and assembly 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 patent applies universality by designing a single cutter arbor that can accommodate multiple disposable carving blades with different eccentric values. The standardized interface and mounting mechanism allow one arbor to perform multiple functions by simply changing the blade, eliminating the need for multiple dedicated cutters for different slot widths.
Solution Approach 2:
The patent segments the carving cutter into two parts: a reusable cutter arbor and disposable carving blades. This segmentation allows the eccentric value to be changed by replacing only the blade rather than the entire cutter assembly, reducing complexity while maintaining precision for various slot widths.
2Ease of manufacture
If conventional disposable blades are used with fixed eccentric values, then manufacturing simplicity is improved, but adaptability to different slot widths deteriorates
Solution Approach 1:
The patent applies parameter changes by varying the eccentric value parameter across different disposable blade designs while maintaining a standardized mounting interface. This allows simple manufacturing of individual blades with fixed eccentric values while achieving high adaptability through parameter variation in the blade selection.
3Adaptability or versatility
If the eccentric value is increased to accommodate larger width radii, then versatility for different slot widths is improved, but cutting precision deteriorates due to excessive eccentricity
Solution Approach 1:
The patent applies dynamics by making the eccentric value adjustable and selectable based on the specific cutting requirement. Instead of using a fixed high eccentric value that compromises precision, the system dynamically selects the appropriate eccentric value by changing the disposable blade, optimizing both versatility and precision for each task.

AI summary
A disposable carving blade (10) contains a central hole (11) defined at a central position thereof, a first central line (15) passing through the central position thereof, a right cutting rim (12) formed on a first peripheral side thereof and a left cutting rim (13) formed on a second peripheral side thereof. The right cutting rim (12) is connected with the left cutting rim (13) to form a V-shaped portion, and the V-shaped portion includes a cutting edge (14) defined on a distal end thereof. An intersection point of the right cutting rim (12) on the first peripheral side of the disposable carving blade and the left cutting rim (13) on the second peripheral side of the disposable carving blade (10) is adjacent to the first central line (15), and a distance between the intersection point and the first central line (15) is a first eccentric value (e).
