Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an image capturing auxiliary device is attached to the laser handpiece, then the image of treatment side can be captured, but the operation becomes complex
Solution Approach 1:
The invention merges the image capturing device with the handpiece body into a single integrated unit. The camera is built into the handpiece, eliminating the need for separate auxiliary devices that need to be attached and detached. This integration resolves the contradiction by maintaining image capturing capability while significantly simplifying the operation for the practitioner.
Solution Approach 2:
The handpiece is designed to perform multiple functions simultaneously - both cutting/treatment and image capturing. By incorporating the camera system into the handpiece body, the device becomes universal, capable of both therapeutic and diagnostic functions without requiring separate equipment, thus improving ease of operation while maintaining measurement precision.
2Measurement precision
If a dental camera is used to observe the inside of mouth, then the treatment site can be visualized, but it cannot be integrated with cutting handpiece
Solution Approach 1:
The invention successfully merges the dental camera system with the cutting handpiece into a single integrated device. The camera, objective lens, and illumination system are incorporated into the handpiece body, allowing simultaneous visualization and cutting functions. This resolves the contradiction by achieving both treatment site visualization and integration with the cutting handpiece.
Solution Approach 2:
The handpiece becomes a universal device capable of both diagnostic imaging and therapeutic cutting functions. By integrating multiple functions into one device, the invention eliminates the need for separate cameras and handpieces, thereby achieving both visualization capability and adaptability with cutting functions.
3Measurement precision
If optical waveguide and image conductor are assembled into handpiece, then image can be recorded, but the configuration is separate system
Solution Approach 1:
The invention combines the optical waveguide for illumination and the image conductor for imaging into a single integrated handpiece system. Rather than maintaining separate systems, both components are incorporated into the same handpiece body with coordinated optical paths, reducing overall system complexity while maintaining image recording capability.
Solution Approach 2:
The optical components are nested within the handpiece structure, with the objective lens, rod fiber, and camera unit arranged in a compact nested configuration. The illumination optical waveguide and imaging optical path are integrated within the same structural envelope, reducing device complexity through efficient spatial arrangement.
