Measuring System Triggering for Precision Speed Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring systems face challenges in accurately correlating measurement values with measurement points on an object, as the determination accuracy of measurement points is inversely related to the movement speed of the measuring instrument, making precise measurements within a short time frame difficult.
Innovation Solution
A measuring system that includes a controller unit with a control module capable of reading position coordinates and triggering signals based on specified coordinate target regions and time, allowing for precise measurement object correlation by synchronizing the measuring instrument's movement with the machine's movement bar, enabling accurate and efficient data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the measuring instrument moves slower during measurement, then the determination accuracy of measurement points is improved, but the measurement time increases
Solution Approach 1:
The patent replaces the mechanical approach of manually controlling measurement speed with an automated trigger-based system. The control unit automatically triggers the measuring instrument at precisely calculated time intervals based on predetermined movement speed and measurement path, eliminating the need for manual speed adjustment while maintaining both accuracy and efficiency
Solution Approach 2:
The system dynamically adjusts the triggering parameters (time intervals, position coordinates) based on the predetermined movement speed and measurement path. By calculating and adjusting these parameters automatically, the system optimizes the balance between measurement speed and determination accuracy without requiring manual intervention
2Productivity
If the measuring instrument moves faster during measurement, then the measurement time is reduced, but the determination accuracy of measurement points deteriorates
Solution Approach 1:
The patent replaces manual control of measurement speed with an automated trigger-based system. The control unit automatically triggers measurements at precisely calculated intervals based on predetermined high-speed movement parameters, enabling fast measurement while maintaining accuracy through automated timing
Solution Approach 2:
The system performs preliminary calculation of trigger intervals and positions based on predetermined movement speed and measurement path before the actual measurement begins. This pre-planning allows the measuring instrument to operate at high speed while ensuring measurements are triggered at optimal moments for maximum accuracy
Data Source
AI summary
A measuring system for acquiring measured values by scanning, including an interface for connection to a control unit of a machine. The system is arranged on a movement axis of the machine, and an object can be measured by a measuring instrument of the system. During the measurement of the object, the measuring instrument generates a measured value that is stored in a control unit, that processes and stores the measured value. The control unit has a control module that reads out a position coordinate from the machine via the interface and compares the read-out position coordinate with a specified coordinate target range, and/or compares a time of a timer with a specified point in time, and releases a trigger signal if the control module detects that the position coordinate lies in the coordinate target range and/or if the time has reached or passed the specified point in time.
