Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual repeated fenestration of tissue with a needle is performed, then tissue disruption can be achieved, but inconsistency and variability occur leading to incomplete repair
Solution Approach 1:
The device incorporates a sensor that provides real-time feedback on tissue disruption status during the procedure. The sensor detects tissue resistance changes and transmits this information to a processor, which then displays feedback to the operator. This feedback mechanism enables consistent tissue disruption by allowing the operator to monitor and adjust the procedure based on objective tissue status data, eliminating the variability inherent in manual repeated fenestration.
Solution Approach 2:
The patent replaces manual mechanical needle fenestration with an automated mechanical device that uses controlled oscillation or rotation of a probe. The automated system provides more consistent tissue disruption compared to manual operation, while the added sensor feedback system ensures reliable completion of the procedure by objectively measuring tissue status throughout the process.
2Measurement precision
If feedback sensor is added to monitor tissue resistance, then procedure completion can be accurately indicated, but device complexity increases
Solution Approach 1:
The sensor provides real-time feedback on tissue resistance during the procedure, enabling accurate measurement of tissue disruption status. This feedback mechanism directly addresses the need for precise measurement of procedure completion, allowing the operator to know exactly when adequate tissue disruption has been achieved.
Solution Approach 2:
The sensor serves multiple functions: it measures tissue resistance, determines procedure completion status, and provides real-time feedback to the operator. By making the sensor multi-functional, the patent reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving accurate measurement.
3Reliability
If real-time feedback is provided during procedure, then variability in clinical outcomes is reduced, but loss of time during procedure increases
Solution Approach 1:
Real-time feedback allows the operator to monitor tissue disruption status continuously and adjust the procedure accordingly. This ensures uniform clinical outcomes by maintaining consistent tissue disruption levels throughout the procedure, preventing both under-treatment and over-treatment that would occur without feedback.
Solution Approach 2:
The feedback sensor operates continuously during the procedure, providing ongoing information about tissue status without requiring interruptions. This continuous monitoring ensures that the procedure maintains optimal parameters throughout, reducing variability in outcomes while minimizing time loss compared to periodic checks.
