Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a practitioner manually identifies tooth parts during dental checkup, then the examination can be performed with human judgment, but the checkup time increases and error rate increases
Solution Approach 1:
The system enables self-service by allowing the three-dimensional scanning device to automatically identify tooth parts without requiring practitioner intervention. The computing unit processes the scanned three-dimensional data and autonomously determines tooth part information, eliminating the time-consuming manual identification process while maintaining high accuracy through automated algorithms.
Solution Approach 2:
The patent replaces the mechanical/manual system of practitioner identification with an automated computational system. The computing unit uses three-dimensional data processing and image generation to substitute human visual inspection and manual recording, thereby reducing checkup time while preserving identification reliability through systematic automated analysis.
2Ease of operation
If a practitioner manually identifies tooth parts, then flexibility in judgment is maintained, but identification precision decreases due to human error
Solution Approach 1:
The system performs self-service by automatically generating three-dimensional images and identifying tooth parts without practitioner intervention. This eliminates human error in identification while maintaining operational simplicity, as the system handles the complex analysis autonomously based on the scanned data.
Solution Approach 2:
The patent creates a three-dimensional digital copy of the tooth structure, which can be analyzed multiple times without degradation. This digital replica allows for precise automated measurement and identification, eliminating the variability inherent in manual human inspection while preserving the ability to re-examine the data if needed.
3Productivity
If automated identification is implemented, then checkup time is reduced, but system complexity increases
Solution Approach 1:
The three-dimensional scanning device is designed with multi-functionality, serving both as a scanning apparatus and an automated identification system. The computing unit integrates multiple functions including data processing, three-dimensional image generation, and tooth part identification, thereby reducing overall system complexity while maintaining high productivity through consolidated functionality.
Solution Approach 2:
The patent introduces a computing unit as an intermediary between the scanning device and the output display. This intermediary handles the complex computational tasks of three-dimensional reconstruction and tooth part identification, allowing the physical scanning device to remain relatively simple while achieving high productivity through sophisticated intermediate processing.
