Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In workpiece production, the high production speed of machinery often results in measurement errors due to the limitations of manual measurement speed, and automatic measurement systems can be affected by production errors, making it challenging to achieve accurate measurements.
Innovation Solution
A measurement system comprising an illumination module, an image pickup device, an angle adjustment module, and a control unit that adjusts the relative angle between the object and the image pickup device to calculate and correct the measurement angle, allowing for accurate image capture and measurement without production errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement is used to prevent production errors from affecting measurement results, then measurement accuracy is improved, but measurement speed decreases and cannot keep up with high-speed production
Solution Approach 1:
The patent replaces manual mechanical measurement with an automatic measurement system that uses image pickup devices (cameras) to capture workpiece images and automatically calculates measurements, eliminating the need for manual intervention while maintaining measurement accuracy and keeping up with high-speed production requirements
Solution Approach 2:
The measurement system performs self-correction by automatically detecting and compensating for production errors through image analysis and calculation algorithms, without requiring external manual adjustment, thus achieving both high speed and accuracy
2Productivity
If automatic measurement system is used to increase measurement speed, then productivity is improved, but production errors adversely affect measurement results
Solution Approach 1:
The system uses feedback mechanisms where the image pickup device captures images, the control unit analyzes the images to detect production errors, and then automatically adjusts measurements based on the detected errors, creating a closed-loop system that maintains accuracy despite high-speed production variations
Solution Approach 2:
The measurement system performs preliminary image capture and error detection before final measurement calculation, allowing it to proactively identify and compensate for production errors that would otherwise affect measurement accuracy
3Measurement precision
If worker manually adjusts workpiece to prevent production errors from affecting measurement, then measurement accuracy is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent replaces complex manual adjustment operations with an automated image-based measurement system that uses software algorithms to compensate for workpiece positioning errors, reducing mechanical complexity while maintaining measurement accuracy
