Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data is unlimitedly accumulated during three-dimensional scanning, then measurement completeness is improved, but system resource consumption increases and data alignment reliability deteriorates
Solution Approach 1:
The patent applies parameter changes by establishing predetermined angle ranges as a critical parameter threshold. Data accumulation is controlled based on whether scan angles fall within these predetermined ranges, transforming the unlimited accumulation approach into a parameter-based selective accumulation strategy. This resolves the contradiction by maintaining measurement completeness within acceptable angular parameters while preventing resource exhaustion and alignment reliability degradation.
Solution Approach 2:
The patent segments the scanning space into multiple predetermined angle ranges, allowing data to be accumulated selectively within each segment. This segmentation approach enables the system to manage data accumulation in a structured manner, ensuring completeness within each angular segment while preventing overall system resource exhaustion, thus improving both measurement completeness and data alignment reliability.
2Measurement precision
If data is unlimitedly accumulated during three-dimensional scanning, then measurement completeness is improved, but system resource consumption increases
Solution Approach 1:
The patent implements parameter changes by introducing predetermined angle ranges as a controlling parameter for data accumulation. Instead of unlimited accumulation, the system selectively accumulates data only when scan angles fall within these predetermined ranges. This parameter-based control maintains measurement completeness within acceptable parameters while significantly reducing system resource consumption by preventing unnecessary data storage and processing.
3Measurement precision
If multi-angle scanning is performed to improve data reliability, then measurement precision is improved, but scanning time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing predetermined angle ranges before the scanning process begins. This allows the system to quickly determine during scanning whether accumulated data meets reliability requirements without performing exhaustive multi-angle scanning. The preliminary definition of acceptable angle ranges enables rapid decision-making, improving data reliability assessment while minimizing scanning time losses.
Solution Approach 2:
The patent implements partial action by accumulating data selectively within predetermined angle ranges rather than requiring complete 360-degree multi-angle scanning. This partial accumulation strategy achieves sufficient data reliability for practical applications without the time cost of exhaustive scanning, resolving the contradiction between measurement precision and time loss.
4Measurement precision
If characteristic information is continuously updated during scanning, then data completeness is improved, but processing complexity increases
Solution Approach 1:
The patent applies parameter changes by using predetermined angle ranges as a control parameter for characteristic information updates. Instead of continuously updating data regardless of scan angle, the system selectively updates characteristic information only when angles fall within predetermined ranges. This parameter-based update strategy maintains data completeness while significantly reducing processing complexity by avoiding unnecessary update operations.

AI summary
A reliability data obtaining system and method using multi-angle scanning includes a scanner configured to scan an object at multi-angles and a controller configured to generate and align real-time three-dimensional (3D) surfaces based on a plurality of pieces of data obtained from the scanner and assign characteristic information to unit cells included in the real-time 3D surfaces obtained via multi-angle scanning. The characteristic information may include a resource density, a curve of an object, an object color, a reliability color, position information, etc. According to the disclosure, a degree of accumulation of the resource density may be limited according to the position information so that data having various angle ranges may be accumulated in each unit cell. Thus, an intraoral model having minimized data distortion and having high reliability may be obtained.
