Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods using specialized devices are used to detect changes in the installed position and direction of measurement devices, then detection accuracy can be maintained, but device complexity and operational difficulty increase
Solution Approach 1:
The patent uses the measurement device's own scanning function to detect changes in its installed state, rather than requiring separate specialized detection devices. The scanning device creates a digital model of the environment and detects changes by comparing successive scans, effectively using the device itself as both the measurement tool and the detection tool, thereby eliminating the need for additional specialized equipment.
Solution Approach 2:
The scanning device is made multi-functional by enabling it to perform both its primary measurement function and the secondary function of detecting changes in its own installed state. The same scanning mechanism and data processing system are used for both measuring environmental features and monitoring secular variations in the device's position and orientation, thereby eliminating the need for separate specialized detection devices.
2Measurement precision
If conventional methods using specialized devices are used to detect changes in the installed position and direction of measurement devices, then detection accuracy can be maintained, but ease of operation deteriorates
Solution Approach 1:
The measurement device performs self-diagnosis by using its own scanning capability to detect changes in its installed state. The device automatically compares successive scans to identify secular variations in position and orientation, eliminating the need for operators to use specialized detection devices or perform manual calibration procedures, thereby significantly improving ease of operation.
Solution Approach 2:
The system implements automatic feedback by continuously monitoring changes in the scanning data and comparing them against expected variations. When secular changes in the installed state are detected, the system automatically identifies and reports the specific changes in position and orientation, eliminating the need for manual detection and adjustment procedures.
3Measurement precision
If the scanning surface does not include visible light, then measurement precision can be maintained for non-visible applications, but ease of operation deteriorates due to difficulty in visual adjustment
Solution Approach 1:
The system provides automatic feedback by analyzing changes in the scanning data to detect secular variations in the installed state. The calculator identifies changes in position and orientation by comparing successive scans, and this information can be presented to the operator electronically, eliminating the need for visual inspection and manual adjustment of the scanning surface alignment.
Solution Approach 2:
The patent replaces manual visual adjustment procedures with automated digital detection and analysis. Instead of requiring operators to visually inspect and mechanically adjust the scanning surface alignment, the system uses computational analysis of scanning data to detect and quantify changes in the installed state, thereby eliminating the need for visual observation of the scanning surface.
4Measurement precision
If secular variation causes the scanning surface to be mismatched with the desired surface, then measurement precision deteriorates, but detecting these changes requires additional specialized devices
Solution Approach 1:
The patent uses the measurement device's own scanning function to detect misalignment caused by secular variation, rather than requiring separate specialized detection devices. The device creates digital models of the environment at different times and compares them to detect changes in scanning surface alignment, effectively using the device itself as both the measurement tool and the detection tool.
Solution Approach 2:
The scanning device is made multi-functional by enabling it to perform both its primary measurement function and the secondary function of detecting misalignment caused by secular variation. The same scanning mechanism and data processing system are used for both measuring environmental features and monitoring alignment changes, thereby eliminating the need for additional specialized detection equipment.

AI summary
According to one embodiments, a calibration detecting apparatus includes a generator, a setting unit, an acquisition unit, and a calculator. The generator generates location data indicating a group including a pair of two positions arranged respectively in two spaces. The setting unit sets an irradiation arrangement so that an irradiating device performs laser irradiation on a region including an end position of the end effector. The acquisition unit acquires observation data indicating whether or not the end effector is observed. The calculator calculates a change in an installed state of the irradiating device based on the observation data.
