Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operator judgment is used to select laser settings, then the system is simple to operate, but the treatment outcomes are unpredictable and highly user-dependent
Solution Approach 1:
The system performs automatic skin analysis and laser parameter selection without requiring operator expertise. The computer vision system captures images, algorithms analyze skin properties, and the system automatically determines optimal laser settings, making the system self-sufficient and eliminating dependency on operator judgment
Solution Approach 2:
The patent replaces manual operator judgment with an automated computer vision system and algorithmic analysis. The mechanical/manual process of visual inspection and subjective decision-making is substituted with optical imaging, digital processing, and automated control systems
2Manufacturing precision
If automated real-time monitoring is implemented, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The system implements real-time feedback by capturing images during laser treatment, analyzing skin response through computer vision, and automatically adjusting laser parameters based on the analysis. This closed-loop feedback system ensures precise treatment while managing complexity through integrated automation
Solution Approach 2:
The patent merges multiple functions into a single integrated system: image capture, skin analysis, laser control, and real-time monitoring are combined into one unified platform. This consolidation improves precision while managing overall system complexity through integration rather than separate components
3Reliability
If personalized computing of laser settings is used, then treatment effectiveness is improved, but processing time increases
Solution Approach 1:
The system performs skin analysis and calculates optimal laser settings in advance before treatment begins. By pre-processing the skin assessment and parameter optimization, the system eliminates time delays during the actual treatment process while maintaining personalized treatment effectiveness
Solution Approach 2:
The computer vision system continuously captures and analyzes skin images throughout the treatment process, enabling real-time adjustments without interrupting the treatment flow. This continuous operation maintains effectiveness while minimizing time loss through seamless processing
4Manufacturing precision
If robotic maneuverability is integrated, then spatial accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The system uses computer vision imaging as an intermediary to guide laser positioning and control. Rather than directly implementing complex robotic maneuverability, the vision system captures spatial information and translates it into precise laser targeting, achieving spatial accuracy through optical mediation
