Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple devices and software are used for scanning and data importing/exporting, then comprehensive data acquisition is achieved, but modeling efficiency deteriorates
Solution Approach 1:
The patent merges multiple scanning functions (gingiva scanning and scanning rod scanning) into a single integrated device. The intraoral scanner is configured to scan both the gingiva and the scanning rod simultaneously or sequentially, eliminating the need to switch between multiple devices and software platforms, thus resolving the contradiction between comprehensive data acquisition and modeling efficiency
Solution Approach 2:
The intraoral scanner is designed with multi-functionality to perform both gingiva scanning and scanning rod scanning using the same device and software. This universal capability allows the system to handle diverse scanning tasks without requiring separate specialized devices, thereby maintaining data comprehensiveness while improving workflow efficiency
2Adaptability or versatility
If data importing and exporting flows are added by using different software, then data compatibility is achieved, but process complexity deteriorates
Solution Approach 1:
The patent combines the data acquisition functions for both gingiva and scanning rod into a single software platform. The same intraoral scanner and processing software handle both types of data, eliminating multiple data importing/exporting flows and reducing process complexity while maintaining the ability to work with different data types
3Measurement precision
If separate scanning processes are used for gingiva and scanning rod, then specialized data quality is maintained, but time consumption deteriorates
Solution Approach 1:
The patent enables continuous scanning operations where the intraoral scanner can transition seamlessly between scanning the gingiva and scanning the scanning rod without requiring device changes or software switches. This continuous operation maintains specialized data quality for each component while significantly reducing the total time required for the scanning process
