Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stereotactic surgery systems or neuro-navigation systems are used to guide cannula placement, then placement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical navigation systems with a simple optical sensor-based probe that provides real-time visual feedback. The probe uses color sensors to detect blood mass location directly at the tip, eliminating the need for expensive stereotactic systems and pre-operative imaging planning.
Solution Approach 2:
The probe performs its own localization function by incorporating color sensors directly at the distal tip. The sensor autonomously detects color changes in real-time as the probe moves through tissue, providing self-guided navigation without requiring external navigation systems or pre-planned trajectories.
2Measurement precision
If real-time color detection is implemented at the probe tip, then blood mass localization precision is improved, but device complexity increases
Solution Approach 1:
The patent places color sensors specifically at the distal tip of the probe where localization is most critical. This localized sensing approach provides high-precision blood detection only where needed, rather than distributing sensors throughout the entire probe structure, thereby maintaining simplicity while achieving precision.
Solution Approach 2:
The probe utilizes color sensors to detect characteristic color changes in tissue that indicate proximity to blood mass. The sensor detects red coloration patterns as the probe approaches blood, providing intuitive visual feedback through simple color transitions that can be displayed to the operator without complex data processing.
3Manufacturing precision
If visual feedback is provided during probe insertion, then surgical precision is improved, but loss of time occurs due to real-time monitoring requirements
Solution Approach 1:
The color sensors operate continuously during probe insertion, providing uninterrupted visual feedback throughout the entire insertion process. This continuous monitoring allows the surgeon to maintain precise control in real-time without intermittent pauses for imaging or repositioning, actually reducing total surgical time despite the added monitoring capability.
Solution Approach 2:
The system provides immediate visual feedback through color changes that directly indicate probe proximity to blood mass. This real-time feedback loop allows the surgeon to make instantaneous adjustments to probe positioning, eliminating the need for trial-and-error maneuvers or repeated insertions that would consume additional time.
