Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor-based intelligence is introduced to pure mechanical surgical devices, then surgical precision and value-added features are improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent introduces an external computing device as an intermediary that performs the intelligent processing functions. Tags with sensors are attached to the mechanical device, but the actual data processing, comparison, and guidance generation occur on the external computing device, allowing the mechanical device to gain intelligence without internal complexity
Solution Approach 2:
The patent replaces complex mechanical design changes with a software-based solution. Instead of redesigning the mechanical device to incorporate intelligence, the system uses tags, sensors, and external computing to provide guidance functionality, substituting mechanical complexity with electronic/software-based approaches
2Adaptability or versatility
If permanent design changes are made to mechanical surgical tools to add intelligence, then functional capabilities are improved, but time consumption and manufacturing cost increase
Solution Approach 1:
The patent attaches tags to the mechanical device beforehand, which can be done during manufacturing or even before use. This preliminary attachment of intelligence components allows the device to gain capabilities without requiring complex redesign or remanufacturing of the entire mechanical system
Solution Approach 2:
The external computing device serves multiple functions: it processes data from various tags, compares spatial information against guidelines, generates guidance, and can assist with multiple different surgical devices. This universal approach allows one system to enhance multiple devices without requiring individual customization for each
3Measurement precision
If tags with sensors are attached to movable arms, then real-time spatial tracking precision is improved, but device complexity and cost increase
Solution Approach 1:
The tags with sensors act as intermediaries that capture spatial data without requiring the mechanical device itself to become complex. The sensors on the tags handle the measurement function, while the external computing device processes the data, separating the measurement function from the mechanical device complexity
Solution Approach 2:
The patent creates a digital copy of the physical device's spatial configuration through tags and sensors. This digital representation allows for precise tracking and comparison without physically modifying the mechanical device's core structure, maintaining simplicity while achieving precision

AI summary
The present disclosure relates to system(s) and method(s) for assisting a surgeon to operate a surgical device. The system is configured to receive real-time spatial data corresponding to a set of movable arms of a surgical device. In one embodiment, each tag may be enabled to capture the real-time spatial data by a set of sensors deployed on each tag with precise coordinate markings. Further, the system receive reference spatial data corresponding to each of the set of movable arms pertaining to the surgical device. The system is configured to compare the real-time spatial data with the reference spatial data to generate a matching score corresponding to each movable arm. The system is configured to identify one or more movable arms, from the set of movable arms with a matching score greater than a predefined threshold score and generate an alert corresponding to the one or more movable arms.
