Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the scanning head is positioned and oriented manually without digital display feedback, then the device structure remains simple, but the control precision and ease of operation deteriorate
Solution Approach 1:
The patent implements digital display means that show the viewing position and viewing direction of the scanning head in real-time. This feedback mechanism allows operators to accurately control the scanning head position and orientation while maintaining awareness of the current state, thereby improving ease of operation without requiring overly complex manual adjustment mechanisms
Solution Approach 2:
The patent replaces complex mechanical positioning mechanisms with a combination of movable scanning head mounted on vehicle means and digital display feedback. Instead of relying solely on精密 mechanical structures for positioning, the system uses digital information display to guide operators, substituting mechanical complexity with informational feedback
2Reliability
If spatial positioning information is not displayed digitally, then the device structure remains simple, but the reliability of interpretation deteriorates
Solution Approach 1:
The digital display means provides real-time feedback on the viewing position and viewing direction, allowing operators to correlate scan results with actual spatial positions. This feedback loop ensures accurate interpretation of scan data by providing contextual positioning information, thereby improving reliability without requiring complex additional hardware
Solution Approach 2:
The digital display acts as an intermediary between the scanning head's physical position and the operator's understanding of the scan results. It translates complex spatial positioning data into comprehensible visual information, mediating the relationship between the scanning system and human interpretation, thereby improving reliability of interpretation
3Adaptability or versatility
If multiple scanning heads with different configurations are used, then the adaptability increases, but the difficulty of detecting and measuring deteriorates
Solution Approach 1:
The patent implements a universal digital display system that shows viewing position and viewing direction regardless of the scanning head configuration. This universal interface works with different scanning head types and vehicle means, providing consistent positional feedback that simplifies interpretation across multiple configurations, thereby maintaining adaptability while reducing interpretation difficulty
Solution Approach 2:
The digital display adapts its displayed parameters based on the scanning head configuration and vehicle means being used. By dynamically adjusting the information presented according to the current setup, the system maintains ease of interpretation across different configurations without requiring complex specialized interfaces for each scenario

Implementation Method 1
shearography also termed speckle pattern shearing interferometry, shearography is a relative interferometric sensing method which furnishes an image as the result showing the difference between two conditions of the test object staggered in time
Implementation Method 2
shearography employs a so-called shearing element which is a shearoptic assembly, such as, for example, an optical wedge, an optical biprism or a Michelson interferometer generating image doubling, i.e. two images of the test object slightly staggered spatially which are overlayed to produce an interferogram due to the resulting interference

AI summary
A device for inspecting a tire (10), in particular by means of an interferometric measuring method, is provided with a measuring head, which is used to scan the tire in order to produce a measured result. The device is also equipped with a location element, which allows the measuring head to be located and aligned in a monitoring position. In addition, the device is provided with a control and display unit, which allows the location element to be controlled and the measured result to be displayed. To achieve the simple control of the measuring head and a reliable evaluation of the measured result, the control and display unit has at least one display field for displaying the monitoring position or the monitoring direction of the measuring head in relation to the tire.
