Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupled vibrators face challenges in achieving appropriate catching and releasing operations, leading to inaccurate vibration detection due to amplitude exceeding allowable ranges and potential contact between mass parts and stopper parts, resulting in incomplete catching and releasing processes.
Innovation Solution
The vibration apparatus employs a control mechanism that applies an intermediate voltage between the holding and release voltages to attenuate vibration energy, and determines the success of catching operations to adjust voltage settings, ensuring accurate catching and releasing by increasing the electrostatic attractive force and amplitude control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mass parts are vibrated by catching and releasing them using the catch and release mechanism, then the vibration detection accuracy is improved, but the amplitude may exceed allowable ranges causing contact between mass parts and stopper parts
Solution Approach 1:
The control circuitry detects the vibration state of the mass parts and determines whether catching is successful or failed based on this feedback. When catching fails, the system adjusts the voltage applied to the electrode unit to increase electrostatic attractive force, ensuring reliable catching operations while maintaining accurate vibration detection within allowable amplitude ranges.
Solution Approach 2:
The system changes the voltage parameter applied to the electrode unit dynamically. By adjusting the voltage level based on catching success determination, the electrostatic attractive force is optimized to reliably catch the mass parts without causing excessive amplitude that would lead to contact with stopper parts.
2Device complexity
If a conventional catch and release mechanism is used, then the structure is simple, but the catching operation is not always successful leading to incomplete vibration detection
Solution Approach 1:
The control circuitry continuously monitors the vibration state to determine whether catching is successful. When catching fails, the system provides feedback by adjusting the voltage to the electrode unit, thereby improving the catching success rate while maintaining the simplicity of the basic catch and release mechanism structure.
Solution Approach 2:
The system replaces purely mechanical catching with an electrostatic field-based approach using the electrode unit. By applying voltage to create electrostatic attractive force, the catching operation becomes more reliable and controllable compared to conventional mechanical mechanisms, while the control circuitry maintains overall system simplicity.
3Reliability
If the amplitude is reduced to prevent contact with stoppers, then the reliability of catching operation is improved, but the vibration energy may be insufficient for accurate detection
Solution Approach 1:
The system optimizes the voltage parameter applied to the electrode unit to achieve the right balance. By carefully controlling the voltage level, the electrostatic attractive force is sufficient to reliably catch the mass parts while limiting the vibration amplitude to prevent contact with stopper parts, thereby maintaining both reliability and detection accuracy.
Solution Approach 2:
The control circuitry uses feedback from vibration state detection to adjust the voltage dynamically. This ensures that the vibration amplitude remains within the optimal range for accurate detection while preventing excessive amplitude that would cause contact with stopper parts, thus maintaining both reliability and measurement precision.
