Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional contact-type or coordinate measuring methods are used, then measurement precision is improved, but productivity deteriorates due to time-consuming manual processes
Solution Approach 1:
The patent replaces manual contact-type measurement methods with a non-contact 3D scanning system using optical components. The imaging device captures multiple images from different angles, and the processing device automatically generates 3D models through computational algorithms, eliminating the need for manual coordinate measurement and significantly improving productivity while maintaining precision
Solution Approach 2:
The patent transforms measurement parameters from manual coordinate data to optical image data. By capturing images with specific light patterns and analyzing their distortion characteristics, the system derives 3D geometric information automatically, changing the measurement approach from point-based manual measurement to image-based automated analysis
2Productivity
If 3D scanners are used to scan objects at high speed, then productivity is improved, but measurement precision deteriorates due to errors in combining multiple scan images
Solution Approach 1:
The patent incorporates feedback mechanisms where the processing device analyzes the consistency and accuracy of combined images continuously. If distortion or misalignment is detected in the merged scan results, the system identifies and corrects errors by adjusting the registration parameters, ensuring high measurement precision even when scanning at high speeds
Solution Approach 2:
The patent introduces an intermediary processing stage that acts as a mediator between raw scan images and final 3D models. This intermediate processing layer performs automatic registration, distortion correction, and quality validation, filtering out errors before they affect the final measurement precision
3Measurement precision
If multiple scan images are combined to obtain complete 3D data, then measurement precision is improved, but loss of time increases due to lengthy data processing
Solution Approach 1:
The patent performs preliminary actions by pre-processing individual scan images to extract key geometric features and calibration data before combining them. By preparing and organizing this preliminary information in advance, the final merging process becomes much faster while maintaining the precision benefits of combining multiple images
Solution Approach 2:
The patent optimizes the merging process by combining multiple scan images through efficient algorithms that automatically register and fuse data from different angles. The processing device integrates these images into a single coherent 3D model much faster than traditional methods, reducing the time loss while preserving measurement precision
4Adaptability or versatility
If manual operations are used for processing artificial dentures, then adaptability is improved for custom treatments, but productivity deteriorates due to labor-intensive processes
Solution Approach 1:
The patent creates a precise digital copy (3D model) of the patient's oral cavity and teeth from scan images. This digital copy serves as a virtual template that can be processed and modified automatically through computer-aided design and manufacturing, maintaining the adaptability for custom treatments while dramatically improving productivity by replacing manual fabrication processes
