Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual monitoring and response to imaging system abnormalities is used, then system complexity is reduced, but response time to abnormalities increases
Solution Approach 1:
The system pre-defines multiple abnormality-handling modes (first mode through fourth mode) that are prepared in advance for different types of imaging abnormalities. When an abnormality is detected, the appropriate pre-defined mode is automatically activated, eliminating the need for manual assessment and response planning. This preliminary preparation of handling strategies significantly reduces response time while maintaining manageable system complexity through structured mode definitions.
Solution Approach 2:
The determination unit continuously monitors image information and provides feedback to the control unit about abnormal states. This closed-loop feedback mechanism enables automatic detection and triggering of appropriate abnormality-handling modes. The system establishes a feedback cycle where image quality assessment results directly control system response actions, reducing reliance on manual monitoring while implementing an automated surveillance system.
2Productivity
If automated abnormality detection and response is implemented, then response speed improves, but device complexity increases
Solution Approach 1:
The abnormality handling system is segmented into distinct operational modes (first mode, second mode, third mode, fourth mode), each designed for specific types of imaging abnormalities. This segmentation allows the complex task of abnormality management to be divided into manageable, specialized sub-functions. Each mode handles specific scenarios independently, improving overall handling efficiency while keeping individual mode complexities low and manageable.
Solution Approach 2:
The system changes operational parameters based on the type of abnormality detected. Different abnormality-handling modes correspond to different parameter configurations (e.g., stopping slave arms, changing control modes, alerting operators). By parameterizing the response based on abnormality type rather than implementing completely different systems for each scenario, the patent achieves high handling efficiency while controlling system complexity through parameter-based adaptation.
3Reliability
If comprehensive abnormality monitoring is implemented, then surgical safety improves, but system complexity increases
Solution Approach 1:
Multiple abnormality-handling modes are defined in advance, each prepared for specific types of imaging abnormalities. This preliminary configuration of safety responses ensures that appropriate safety actions are ready to be executed immediately when abnormalities occur, enhancing surgical safety without requiring complex real-time decision-making systems. The safety mechanisms are pre-configured based on anticipated abnormality scenarios.
Solution Approach 2:
Different parts of the system receive different types of control based on the specific abnormality detected. For example, some modes stop slave arms completely, while others merely alert operators or change control parameters. This localized, targeted response to specific abnormality types provides comprehensive safety coverage while avoiding unnecessary complexity in the overall monitoring system. Each monitoring and response component is optimized for its specific function.

AI summary
According to one embodiment, a surgical system includes an imaging system, a determination unit, and a control unit. The imaging system is configured to acquire image information. The determination unit is configured to determine, based on the image information, whether an abnormal state has occurred in the surgical system. The control unit is configured to switch to an abnormality time control mode of executing abnormality-handling processing, when the determination unit determines that an abnormal state has occurred.
