Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive equipment and software are used for virtual nose shaping, then the quality and precision of virtual shaping is improved, but the accessibility and ease of operation deteriorates
Solution Approach 1:
The patent uses a mobile device camera to capture facial images and creates a 2D copy of the patient's facial features. This digital copy is then used for virtual nose shaping without requiring expensive 3D scanning equipment. The system processes these captured images to generate virtual shaping results, making the technology accessible through common mobile devices while maintaining functional precision.
Solution Approach 2:
The patent replaces expensive, specialized medical equipment with inexpensive, widely available mobile devices. By using standard smartphone cameras and processors, the system eliminates the need for costly dedicated virtual shaping equipment, thereby improving accessibility while providing sufficient functionality for clinical use.
2Adaptability or versatility
If complex software is used for virtual nose shaping, then the functionality and accuracy is improved, but the device complexity and ease of operation worsens
Solution Approach 1:
The patent divides the virtual nose shaping process into distinct modular components: facial image capture, reference point detection, nose line drawing, and result display. Each module performs a specific function independently, simplifying the overall system architecture. The control unit coordinates these segmented functions, making the software easier to implement and maintain while retaining comprehensive functionality.
Solution Approach 2:
The patent creates a universal virtual nose shaping system that can be implemented on any mobile device with a camera. The same software architecture handles various facial types, different nose shaping preferences, and multiple reference point configurations, making the system highly adaptable without increasing complexity for the end user.
3Manufacturing precision
If detailed reference points and angles are set for virtual nose shaping, then the precision and naturalness of shaping is improved, but the time and complexity of operation increases
Solution Approach 1:
The patent automatically detects and sets multiple reference points (glabella, nasal dorsum, rhinion, supratip, nasal tip, columnella, subnasale, and pogonion) and calculates reference angles before the actual nose line drawing. By performing these preparatory actions automatically, the system eliminates manual measurement time while ensuring precise positioning for accurate virtual shaping.
Solution Approach 2:
The system provides real-time feedback by displaying the detected reference points and calculated angles to the user during the shaping process. This allows the operator to verify the automatic detection results and make minor adjustments if needed, ensuring high precision without requiring extensive manual setup time.
