Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring objects with coordinate measuring devices are inefficient, requiring long measurement durations, high computing effort, and large data storage capacity, which increases process time and costs.
Innovation Solution
A method to dynamically adjust the measurement strategy by changing measurement quality-relevant parameters, such as reducing the number of measurement points or increasing relative movement speed, when the measurement quality exceeds a predetermined minimum, to reduce measurement time, computing effort, and data storage requirements while maintaining target quality standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of measurement points are acquired to improve measurement quality, then measurement quality is improved, but measurement duration increases
Solution Approach 1:
The patent applies dynamics by making the measurement strategy adaptive rather than static. The system dynamically adjusts measurement parameters (number of measurement points, scanning speed) based on real-time assessment of actual measurement quality versus target quality, enabling the measurement process to optimize itself during execution
Solution Approach 2:
The patent changes measurement parameters (number of measurement points, scanning speed) based on the assessed measurement quality. When quality exceeds the target, parameters are adjusted to reduce measurement points and increase speed, thereby resolving the contradiction between measurement quality and measurement duration
2Measurement precision
If a large number of measurement points are acquired to improve measurement quality, then measurement quality is improved, but computational effort increases
Solution Approach 1:
The system changes the parameter of number of measurement points based on quality assessment. When measurement quality exceeds the target, the system reduces the number of measurement points, thereby reducing computational effort while maintaining sufficient quality
Solution Approach 2:
The patent implements feedback by continuously assessing measurement quality during the measurement process and using this information to adjust the measurement strategy. The feedback loop enables the system to reduce computational effort when quality targets are already met
3Measurement precision
If a large number of measurement points are acquired to improve measurement quality, then measurement quality is improved, but data storage capacity required increases
Solution Approach 1:
The system adjusts the parameter of number of measurement points based on quality assessment. When quality exceeds the target, fewer measurement points are taken, directly reducing the data storage capacity required
4Measurement precision
If the speed of relative movement between object and sensor is reduced to improve measurement quality, then measurement quality is improved, but measurement duration increases
Solution Approach 1:
The patent changes the scanning speed parameter based on quality assessment. When measurement quality exceeds the target quality, the system increases the scanning speed, thereby reducing measurement duration while maintaining sufficient quality
Solution Approach 2:
The system dynamically adjusts scanning speed during the measurement process based on real-time quality assessment, enabling adaptive optimization of the trade-off between measurement quality and measurement duration
