Temporal Synchronization of Contactless Scanning on Moving Glass Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Temporal synchronization between automatic movement means and contactless detection means in quality control systems for glass products is challenging due to independent control modules and differing time origins, leading to inaccurate measurements of physical parameters along curved surfaces.
Innovation Solution
A method for temporal synchronization involves recording spatial coordinates and signals from both systems, searching for reference positions and signals, and translating time scales to align them, with optional use of a correlation function for efficient resynchronization and marker-based signal differentiation.

Engineering Contradiction Analysis
1Device complexity
If independent control modules are used for movement means and detection means to simplify system architecture, then temporal synchronization between spatial coordinates and measurement signals cannot be achieved
Solution Approach 1:
A timestamp field serves as a temporal intermediary that bridges the independent control modules of the movement means and detection means. Each spatial coordinate is tagged with its emission timestamp, and each measurement signal is time-stamped. These timestamps act as mediators that enable correlation between the two independent systems without requiring their control modules to be integrated or synchronized at the hardware level.
Solution Approach 2:
The system implements a feedback mechanism where the recorded timestamps from the movement means are used by the detection means to determine which spatial coordinate corresponds to each measurement. This feedback loop of timestamp comparison and matching enables temporal synchronization to be achieved through data processing rather than through tight control module integration.
2Adaptability or versatility
If different time origins are used by movement means and detection means to maintain independent operation, then accurate matching of spatial coordinates with measured parameters becomes impossible
Solution Approach 1:
Timestamps serve as universal temporal intermediaries that are independent of the time origins used by each system. Even though the movement means and detection means use different time origins, the timestamp field provides a common temporal reference framework that allows accurate matching. The timestamp acts as a mediator that translates between the two different time systems, enabling correlation without requiring unified time origins.
