Linear Motor Assembly Clock Synchronization for Fault Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current linear motor systems in industrial applications, such as packaging assemblies, lack a robust and automatic method for error detection and synchronization of movable members, leading to imprecise sensor measurements and potential operational failures.
Innovation Solution
A linear motor system with a synchronization device that transmits a synchronization signal to movable members, allowing their processing units to adjust internal clocks and timestamp data synchronously, ensuring precise data correlation between on-board and off-board systems, thereby enhancing the accuracy of position and condition control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator checking or position error sensors are used to monitor package handling, then error detection capability is provided, but the system lacks automatic real-time monitoring and direct measurements of the forming and sealing process
Solution Approach 1:
The patent implements feedback by equipping movable members with processing units that collect data from sensors during the forming and sealing process, transmit this data to a central system, and enable real-time monitoring and automatic error detection, replacing manual checking with automated feedback loops
Solution Approach 2:
The system performs self-monitoring through onboard sensors and processing units that automatically detect errors and transmit data without requiring external operator intervention, enabling the system to monitor its own operation and detect failures autonomously
2Measurement precision
If movable members operate independently without synchronization, then system simplicity is maintained, but sensor measurements become imprecise and failure detection is delayed
Solution Approach 1:
The patent implements periodic synchronization where a central system periodically transmits synchronization signals to movable members at defined intervals, ensuring that all sensors and processing units operate on a synchronized timeline while maintaining operational simplicity through regular periodic updates rather than continuous complex coordination
