Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial hoppers and grinding tubes often experience buildup, which is difficult to detect and remove, especially in hard-to-access locations, leading to operational issues and potential system downtime.
Innovation Solution
A method involving a sensor and excitation unit that imparts vibrations to the component, analyzing changes in vibrational characteristics to detect buildup, and applying a second vibration to remove it, utilizing resonance frequencies and impulse excitations to effectively clear material accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If conventional detection methods are used for buildup, then detection is possible, but the component must be accessed directly which is difficult for hard-to-reach locations
Solution Approach 1:
The patent uses vibration sensors and excitation units as intermediary devices attached to the component to detect buildup indirectly through vibrational changes, eliminating the need for direct visual inspection or physical access to hard-to-reach areas where buildup occurs
2Productivity
If the system operates continuously without maintenance, then productivity is maintained, but buildup accumulates and adversely affects operation
Solution Approach 1:
The patent implements a feedback mechanism where vibration sensors continuously monitor the component's vibrational characteristics, and when changes indicating buildup are detected, the system automatically triggers an excitation unit to remove the buildup, allowing continuous operation without manual intervention or downtime
Solution Approach 2:
The system performs self-diagnosis and self-cleaning by using sensors to detect buildup and automatically activating excitation units to remove it, enabling the component to maintain its own reliability without external maintenance intervention
3Reliability
If vibration-based detection and removal is implemented, then buildup can be detected and removed, but additional components (sensors and excitation units) are added to the system
Solution Approach 1:
The excitation unit serves multiple functions: it can be used to remove buildup during normal operation and can also serve as part of the detection system by providing the vibrational excitation needed to measure resonant frequency changes, reducing the need for separate dedicated components

Data Source
AI summary
In a method for operating a system, a first vibration is imparted to a component of the system and the first vibration of the component is detected by a sensor. The sensor generates a sensor signal for transmission to a control device, which analyzes the sensor signal and determines whether a buildup is present on the component based upon the analysis of the sensor signal. A second vibration is imparted to the component to remove the buildup when the buildup has been detected.
