Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid fixed connection is used between the anatomic orifice device and the robot-assisted medical system, then mechanical stability is improved, but patient safety deteriorates due to dislodgement risk from patient motion
Solution Approach 1:
The connection member incorporates a flexible member that allows dynamic adjustment and movement to accommodate patient motion while maintaining connection integrity. This flexible connection enables the system to adapt to changing spatial relationships caused by patient breathing and movement, preventing dislodgement while maintaining mechanical stability.
Solution Approach 2:
The system uses sensors to detect spatial relationship parameters and dynamically adjusts the mounting bracket position and orientation in response to detected motion, changing the connection parameters in real-time to maintain secure engagement despite patient movement.
2Reliability
If a flexible connection is used to accommodate patient motion, then patient safety is improved by reducing dislodgement risk, but mechanical stability deteriorates due to connection looseness
Solution Approach 1:
The flexible member provides controlled flexibility that accommodates motion while maintaining sufficient mechanical stability through its elastic properties and geometric design, achieving a balance between adaptability and structural integrity.
Solution Approach 2:
Sensors continuously monitor the spatial relationship and connection status, providing feedback to the control system which adjusts the mounting bracket to maintain optimal mechanical stability while accommodating necessary motion for patient safety.
3Device complexity
If manual alignment and coupling procedures are used, then device complexity is reduced, but productivity deteriorates due to time-consuming coupling procedures
Solution Approach 1:
The system employs self-aligning features and automated sensor-based detection that enable the mounting bracket and connection member to automatically find and establish proper alignment without requiring complex manual positioning procedures, improving coupling efficiency while maintaining reasonable device complexity.
Solution Approach 2:
The patent replaces manual mechanical alignment procedures with sensor-based spatial relationship detection and automated control system guidance, substituting human operator skill with automated sensing and actuation to accelerate the coupling process.
4Productivity
If automated sensor-based alignment is implemented, then productivity is improved through faster coupling, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The system uses optical or electromagnetic sensors to detect spatial relationships, replacing complex manual mechanical measurement and alignment procedures with non-contact sensing that simplifies the overall interaction while adding automated detection capabilities.
Solution Approach 2:
The sensor system and control architecture are designed to perform multiple functions including alignment detection, connection verification, and motion monitoring, reducing the need for separate dedicated systems and thereby limiting the increase in overall device complexity.
