Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tools face challenges in completely and smoothly removing burrs due to foreign substances attachment and are limited in their ability to handle surfaces of various shapes and sizes.
Innovation Solution
A deburring tool design featuring a cutting unit with a blade part that protrudes outwardly due to fluid injection, allowing for adjustable blade extension and rotation, along with a pressing unit and fixing unit to control the cutting unit's movement and angle, ensuring effective deburring regardless of debris presence and surface complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed blade is used in the deburring tool, then the structure is simple, but the tool cannot adapt to surfaces of various shapes and sizes
Solution Approach 1:
The cutting unit is designed to be movable rather than fixed, allowing it to adjust its position and protrusion degree according to different workpiece geometries. The cutting unit can move along the rotation axis direction and rotate around the rotation axis, enabling adaptation to various surface shapes and sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The deburring tool is divided into distinct functional modules: a rotation unit for rotating the tool, a cutting unit with the blade for cutting, and a movement unit for controlling the cutting unit's position. This segmentation allows each module to be optimized independently while working together to achieve versatility across different workpiece types.
2Reliability
If foreign substances are present during deburring, then debris removal is needed, but the deburring process cannot be performed completely or smoothly
Solution Approach 1:
The movement unit is designed to utilize the presence of foreign substances or debris as a signal to activate the cutting unit's adjustment. When debris is detected or anticipated, the movement unit adjusts the cutting unit's position and rotation to optimize cutting conditions, converting the harmful presence of debris into a trigger for adaptive action that ensures complete deburring.
Solution Approach 2:
The system incorporates feedback mechanisms where the presence of debris or the cutting resistance provides information to the movement unit, which then adjusts the cutting unit's parameters accordingly. This feedback loop ensures that the deburring process continues smoothly and completely even when foreign substances are present.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool enables efficient and complete deburring on diverse surface shapes and sizes by controlling blade protrusion and rotation, effectively removing debris and ensuring smooth operation.
Implementation Method 1
when a fluid supplied from the outside of the deburring tool through the first channel is injected into the cutting unit and presses the cutting unit, the cutting unit may move and a degree to which the blade part protrudes outwardly may increase
Implementation Method 2
When the fluid supplied from the outside of the deburring tool through the first channel is injected into the bottom surface of the cutting unit, the cutting unit may rotate with respect to the rotating shaft
