Conveyor Display Prioritization Using Absolute Movement Amount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conveyor systems, when multiple abnormal locations are detected, it is difficult to determine which ones to prioritize for checking, as existing systems only display these locations without providing clear indicators of their severity.
Innovation Solution
An information display device that acquires absolute movement amounts based on acceleration information along the transportation path and displays this information alongside abnormality data, allowing for prioritization of locations with significant vibrations as potential failure points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple abnormal locations are displayed without priority indication, then all abnormal locations can be identified, but it becomes difficult to determine which one to check first
Solution Approach 1:
The patent applies color coding to represent different priority levels of abnormal locations. Locations with larger absolute movement amounts (indicating more serious vibrations) are displayed in different colors than those with smaller movement amounts, enabling operators to quickly identify and prioritize critical locations without losing information about all abnormal locations.
Solution Approach 2:
The patent uses the parameter of absolute movement amount (derived from acceleration information) to differentiate priority levels. By calculating and displaying this parameter for each abnormal location, the system transforms raw vibration data into actionable priority information, allowing operators to sort and focus on the most critical locations first.
2Reliability
If fixed detecting units are mounted around the conveyor device, then fault detection can be performed, but the detection range is limited
Solution Approach 1:
The patent makes the container serve multiple functions: it acts as both the object to be transported and as a mobile detection platform. By mounting detecting units on the container, the system achieves wide-area coverage along the entire transportation path without requiring fixed detectors at every location, thus expanding detection range while maintaining fault detection capability.
Solution Approach 2:
The patent transitions from static fixed detectors to dynamic mobile detectors mounted on moving containers. This allows the detection system to move with the transported objects, covering the entire transportation path dynamically rather than requiring static coverage of all areas, thereby expanding the effective detection range.
