Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional CO2 laser or Philip knife treatment is used, then the treatment can be performed with existing equipment, but the surgery time is long (5-30 minutes) and surgeon workload is high
Solution Approach 1:
The patent replaces manual mechanical laser operation with an automated robotic system that uses image guidance and computer control to perform the treatment. The robotic arm automatically positions and moves the laser applicator based on pre-planned treatment paths, eliminating the need for manual positioning and reducing surgery time while maintaining precision.
Solution Approach 2:
The system changes the operational parameters by implementing automated control of laser delivery parameters (power, duration, positioning) based on image-guided treatment planning. This automation allows for optimized treatment parameters to be consistently applied, reducing variability and improving efficiency compared to manual operation.
2Ease of operation
If manual laser operation is used, then the equipment is simple to operate, but high surgeon expertise and experience are required leading to complex treatment courses
Solution Approach 1:
The system performs self-positioning and self-navigation functions through integrated image guidance and automated control. The robotic system automatically calculates treatment paths, positions the laser applicator, and executes the treatment protocol without requiring extensive manual intervention or expert judgment during the procedure, making complex automated functions accessible to operators with less specialized training.
3Device complexity
If non-visual operation is used, then the equipment structure is simple, but the treatment cannot be recorded by pictures or video for follow-up work
Solution Approach 1:
The patent merges the imaging system, robotic control system, and laser treatment system into an integrated platform. The image guidance system captures real-time images and videos during treatment, which are then used by the robotic system for precise positioning and treatment execution. This integration allows treatment documentation to be automatically captured and stored without adding significant structural complexity, as the imaging and control functions are combined in a unified system.
4Manufacturing precision
If manual positioning is used, then the device structure is simple, but the positioning precision and treatment accuracy are limited by surgeon eyesight
Solution Approach 1:
The system replaces manual visual positioning with an automated image-guided robotic positioning system. The robotic arm uses computer vision and pre-planned treatment paths to automatically position the laser applicator with high precision, eliminating the limitations of human eyesight and manual dexterity. This substitution significantly improves positioning accuracy while the automation handles the complexity of precise control.
