Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the surface density device is used for a long time, then the device continues to operate and maintain productivity, but the relative position between the radiation source and ionization chamber changes leading to measurement inaccuracy
Solution Approach 1:
The patent implements a feedback mechanism by continuously monitoring the poses of the radiation source and ionization chamber during operation. The detection module obtains current poses, calculates pose deviations from initial poses, and uses this information to determine whether pose changes have occurred, enabling real-time correction of measurement results while maintaining continuous operation
Solution Approach 2:
The patent applies preliminary action by detecting and recording the initial poses of the radiation source and ionization chamber before measurement begins. This preliminary pose information is stored and used as a reference for subsequent real-time detection and comparison during continuous operation, allowing for accurate deviation calculation
2Measurement precision
If the device stops to correct pose changes, then measurement accuracy is improved, but measurement efficiency and productivity decrease
Solution Approach 1:
The patent ensures continuity of useful action by implementing real-time pose detection and correction during measurement operation. The system continuously obtains current poses, calculates deviations, and corrects measurement results without interrupting the measurement process, thereby maintaining both high accuracy and productivity
Solution Approach 2:
The patent replaces mechanical adjustment systems with an automated detection and correction system. Instead of physically adjusting the positions of the radiation source or ionization chamber, the system uses detection modules to monitor poses and applies computational correction to measurement results, eliminating the need for manual intervention and maintaining continuous operation

Function Achieved in This Case
Enhances measurement accuracy by enabling real-time detection and correction of pose changes, maintaining measurement efficiency without stopping the device.
Implementation Method 1
the radiation source emits rays to the object under measurement. The rays pass through the object under measurement and enter the ionization chamber
Implementation Method 2
the ionization chamber determines a thickness and/or density of the object under measurement according to the degree of attenuation of the rays
Data Source
AI summary
A detection method includes obtaining, during operation of a surface density device, a first current pose of a radiation source of the surface density device and a second current pose of a ionization chamber of the surface density device; ascertaining a first pose deviation of the radiation source based on the first current pose; ascertaining a second pose deviation of the ionization chamber based on the second current pose; and determining whether the radiation source has undergone a pose change with respect to the ionization chamber based on the first pose deviation and the second pose deviation.
