Cased Carbide Deburring Tool for Safer Edge Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual deburring tools, such as carbide plates, pose risks of cuts to operators and scratches to workpieces, leading to quality issues and prolonged operation times, especially in the aeronautical field.
Innovation Solution
A manual deburring tool with a casing that houses a consumable carbide plate, exposing only the deburring edges through openings, providing operator protection and reducing workpiece damage, featuring a plastic casing with anti-slip properties and adjustable openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carbide plate is used for deburring, then deburring function is achieved, but operator safety deteriorates due to cut risks
Solution Approach 1:
A casing made of robust plastic material is introduced as an intermediary between the operator and the carbide plate. The casing encloses the plate while providing openings that expose only the deburring edges, allowing the operator to handle the tool without direct contact with the sharp carbide plate, thus eliminating cut risks while maintaining operational effectiveness
2Manufacturing precision
If a carbide plate is used for deburring, then deburring function is achieved, but workpiece quality deteriorates due to scratches and shocks
Solution Approach 1:
The casing acts as a protective intermediary that interfaces with the workpiece instead of the carbide plate directly. Only the necessary deburring edges are exposed through controlled openings, minimizing the risk of accidental scratches and shocks to the workpiece surface while maintaining the deburring function
Solution Approach 2:
The casing is made of robust plastic material that provides a flexible yet protective enclosure. This material choice allows the casing to absorb minor impacts and prevent direct transmission of shocks to the workpiece, while the controlled openings ensure the deburring edges remain accessible for effective operation
3Reliability
If a casing is added to house the carbide plate, then operator protection is improved, but device complexity increases
Solution Approach 1:
The casing is designed as a segmented structure with strategic openings positioned to expose only the deburring edges of the carbide plate. This segmentation allows the protective function to be achieved while maintaining simplicity - the openings are precisely located to provide necessary access without requiring complex mechanisms or additional components
4Productivity
If openings are created in the casing to expose deburring edges, then deburring effectiveness is maintained, but operator safety could deteriorate if openings are too large
Solution Approach 1:
The openings in the casing are strategically designed with specific dimensions and positions that expose only the deburring edges of the carbide plate. This local quality approach ensures that the openings are large enough to allow effective deburring operation but small and precisely positioned enough to prevent operator contact with other parts of the carbide plate, thus maintaining both productivity and safety

AI summary
A manual deburring tool including a consumable carbide plate having deburring edges, and a casing which is configured to be grasped manually and has an internal cavity for housing the plate, the casing including a body and a cover removably attached to the body so as to allow the insertion of the plate into the cavity and the removal of said plate from the cavity, the housing including at least one opening that opens into the cavity and exposes a deburring edge.
