Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration grinders with a single motor as a vibration source are inefficient for treating complex surfaces due to a fixed single directional flow pattern, which limits grinding efficiency and prevents abrasives from reaching curved surfaces, resulting in incomplete surface treatment.
Innovation Solution
A grinding cavity body with multiple ultrasonic vibration sources, classified as strong and weak, generating different frequencies to create a multi-directional flow pattern, allowing the abrasive slurry to flow and vibrate effectively in various directions, enhancing grinding efficiency and reaching complex surface features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single motor is used as the vibration source, then the device structure is simple, but the grinding efficiency is limited and the flow pattern is fixed in a single direction
Solution Approach 1:
The single motor vibration source is segmented into multiple ultrasonic vibration sources (at least three) with different vibration directions. Each vibration source independently generates ultrasonic vibrations in different directions, creating a multi-directional flow pattern that enhances grinding efficiency and enables treatment of complex surfaces.
2Productivity
If a single fixed flow pattern is used, then the device structure is simple, but the abrasive cannot reach curved deep surfaces and complex surface features
Solution Approach 1:
The fixed single-directional flow pattern is transformed into a dynamic multi-directional flow pattern by using multiple vibration sources with different vibration directions. The system can adaptively create flow patterns in various directions to reach curved deep surfaces and complex surface features that cannot be accessed by a single fixed flow pattern.
3Loss of time
If a single vibration direction is used, then the rubbing between abrasive and workpiece is unidirectional, but the grinding procedure becomes time-consuming for complex surfaces
Solution Approach 1:
The single vibration direction is segmented into multiple vibration directions using at least three ultrasonic vibration sources. Each vibration source vibrates in a different direction, creating multi-directional rubbing between the abrasive and workpiece surface, which significantly reduces grinding time for complex surfaces.
4Productivity
If a motor with low vibration frequency is used, then the device structure is simple, but the grinding is limited to macroscopic flow direction only
Solution Approach 1:
The conventional motor vibration source is replaced with ultrasonic vibration sources that generate high-frequency vibrations. This substitution enables not only macroscopic flow direction grinding but also microscopic surface treatment, significantly enhancing overall grinding performance.
