Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable component is used in the surgical system, then the adaptability and ease of repair are improved, but the reliability of electrical connection and detection is worsened
Solution Approach 1:
The patent implements a feedback mechanism where the sensor circuit continuously monitors the electrical connection state between the detachable component and console. The sensor circuit detects changes in electrical characteristics (such as impedance or conductivity) that occur when the detachable component is attached or detached, and provides feedback signals to the controller. This allows the system to automatically detect and respond to connection states, ensuring reliable operation despite the detachable nature of the component.
Solution Approach 2:
The patent introduces an intermediary detection mechanism (the sensor circuit and electrical isolation device) between the detachable component and the main system. This intermediary layer safely detects the connection state through isolated electrical measurements, allowing the system to determine whether the detachable component is properly attached without creating direct electrical hazards. The intermediary approach maintains reliability by providing a safe detection buffer zone.
2Object-affected harmful factors
If electrical isolation is implemented for safety, then the protection against electrical hazards is improved, but the complexity of the electrical arrangement increases
Solution Approach 1:
The electrical isolation device serves as an intermediary element that physically and electrically separates different parts of the system while still allowing functional communication. The isolation device includes isolated electrical connections that prevent direct electrical contact between the detachable component and the main console, blocking harmful electrical currents while permitting controlled detection signals to pass through. This intermediary approach provides safety without requiring complete system redesign.
Solution Approach 2:
The patent replaces complex mechanical safety mechanisms with electrical isolation technology. Instead of using mechanical switches, physical disconnects, or complex interlocking mechanisms to ensure safety, the system uses electrical isolation devices that provide automatic electrical separation. This substitution reduces mechanical complexity while maintaining or improving safety performance through more reliable electrical isolation.
3Measurement precision
If state detection and feedback control are added, then the precision of therapeutic function control is improved, but the device complexity increases
Solution Approach 1:
The sensor circuit is designed to perform multiple functions within a single integrated structure. It simultaneously detects the attachment state of the detachable component, monitors electrical connection integrity, and provides feedback signals for therapeutic control. This multi-functional approach consolidates what could be separate complex systems into a unified circuit, reducing overall device complexity while maintaining high measurement precision for state detection.
Solution Approach 2:
The detection system is designed to be self-regulating and self-monitoring. The sensor circuit automatically detects changes in electrical characteristics and generates appropriate feedback signals without requiring external intervention or complex processing. The system uses its own operational signals to perform the detection, essentially using the therapy signal paths themselves as the detection medium, which eliminates the need for separate complex detection hardware.
