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 effective processing of curved or deep surface areas.
Innovation Solution
A grinding cavity body with multiple ultrasonic vibration sources, allowing for adjustable frequencies and amplitudes to create a multi-directional flow pattern, enabling the abrasive to reach and process complex surfaces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor is used as the vibration source, then the device structure is simple, but the grinding efficiency is limited due to fixed single directional flow pattern
Solution Approach 1:
The single motor vibration source is segmented into multiple ultrasonic vibration sources arranged in specific patterns (rectangular, triangular, or circular arrays). This segmentation allows independent control of each vibration source, enabling multi-directional flow patterns while maintaining manageable device complexity through modular configuration.
Solution Approach 2:
The system transitions from a static single-directional flow pattern to a dynamic multi-directional flow pattern by independently controlling the amplitude and frequency of multiple vibration sources. This allows real-time adjustment of flow directions to match complex surface geometries, significantly improving grinding efficiency.
2Device complexity
If a single motor is used as the vibration source, then the device structure is simple, but the processing of complex surfaces and curved deep surfaces is ineffective
Solution Approach 1:
Different regions of the cavity body receive targeted vibration from specific ultrasonic sources, creating localized flow patterns adapted to specific surface features. This allows the system to address complex surfaces with varying geometries by concentrating abrasive flow where needed most.
Solution Approach 2:
The system adds directional dimensions to the abrasive flow by using multiple vibration sources arranged in three-dimensional configurations. This transforms the single-directional flow into multi-directional flow that can access curved deep surfaces and complex geometries from multiple angles simultaneously.
3Use of energy by stationary object
If a single motor is used as the vibration source, then the equipment cost is low, but the processing time for complex surfaces is excessive
Solution Approach 1:
Multiple ultrasonic vibration sources operate simultaneously to create continuous multi-directional abrasive flow, eliminating idle time between directional changes. This continuous action on multiple fronts reduces total processing time while using cost-effective ultrasonic technology.
Solution Approach 2:
The system uses periodic modulation of vibration frequencies and amplitudes across multiple sources to create oscillating flow patterns that systematically cover complex surfaces. This periodic action ensures thorough coverage of difficult-to-reach areas without extending processing time.
4Ease of operation
If a single motor is used as the vibration source, then the device is simple to operate, but the abrasive cannot reach curved deep surfaces
Solution Approach 1:
The arrangement of multiple ultrasonic vibration sources in three-dimensional space creates abrasive flow that propagates in multiple directions, enabling the abrasive to reach curved deep surfaces and complex geometries that are inaccessible to single-directional flow from a single motor.
