Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tension measuring device is integrated into surgical forceps, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the force sensor, amplifier, and display components into an integrated surgical forceps device. The force sensor is embedded within the jaw structure, allowing direct measurement of tension forces during surgical procedures without requiring separate measurement equipment.
Solution Approach 2:
The forceps device performs multiple functions: it provides the standard surgical function of grasping and manipulating tissue while simultaneously measuring tension forces. The same device structure serves both as a surgical instrument and a measurement device, eliminating the need for separate equipment.
2Measurement precision
If force sensors are embedded in jaw members, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The force sensor is embedded directly within the jaw member structure, allowing the jaw itself to perform the measurement function. The sensor automatically detects forces applied during surgical manipulation without requiring separate measurement procedures or additional manual operations by the surgeon.
Solution Approach 2:
The patent replaces traditional mechanical measurement methods with electronic force sensors. The sensor converts mechanical forces into electrical signals that can be displayed digitally, eliminating the need for mechanical gauges or manual measurement techniques that would complicate the surgical workflow.
3Reliability
If continuous data acquisition is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The force sensor and display system operate continuously throughout the surgical procedure, providing real-time feedback on tension forces. The system maintains continuous data acquisition without requiring intermittent manual readings or separate measurement steps, ensuring reliable measurement throughout the entire surgical workflow.
Solution Approach 2:
The patent implements a feedback system where the force sensor continuously monitors tension forces and displays the information to the surgeon during the procedure. This real-time feedback allows the surgeon to adjust surgical techniques based on actual force measurements, improving reliability of surgical outcomes while the continuous operation is handled automatically by the electronic system.
