Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive data collection and analysis systems are implemented, then surgical outcome precision is improved, but device complexity increases
Solution Approach 1:
The system segments data collection across multiple sources including wearable sensors on the patient, electronic health records, intraoperative robotic systems, and postoperative monitoring devices. Each component collects and transmits data independently to a centralized processing system, dividing the complex data gathering task into manageable segments that can be developed, deployed, and maintained separately while contributing to the overall precise surgical planning.
Solution Approach 2:
A centralized processing system acts as an intermediary between diverse data sources and the surgical planning interface. This intermediary receives raw data from multiple heterogeneous sources, processes and integrates it using machine learning algorithms, and presents synthesized treatment recommendations to surgeons. The intermediary layer abstracts the complexity of data integration from the surgical workflow, maintaining precision while managing system complexity.
2Reliability
If personalized treatment plans based on multiple data sources are created, then surgical effectiveness is improved, but information processing requirements increase
Solution Approach 1:
The system performs preliminary data processing and analysis before the surgical procedure. Wearable sensors collect patient-specific kinematics data during prehabilitation activities, and machine learning algorithms analyze this data along with EHR information to predict surgical outcomes and recommend optimal treatment parameters. This preliminary action ensures that when the surgeon reviews the treatment plan, the information is already processed and synthesized, reducing the information processing load during the actual surgical decision-making process.
Solution Approach 2:
The system implements feedback loops where postoperative outcomes from previous patients are fed back into the machine learning models to continuously improve treatment recommendations. Intraoperative data from robotic systems and postoperative recovery data are used to refine predictions for future patients. This feedback mechanism enhances surgical effectiveness over time while the system learns to process information more efficiently, reducing the processing load as the models become more sophisticated.
3Manufacturing precision
If wearable sensors are used to collect patient-specific kinematics data, then treatment plan accuracy is improved, but ease of operation decreases
Solution Approach 1:
The wearable sensors are designed to be multi-functional, serving both as data collection devices and as user-friendly wearables that patients can easily use during daily activities and prehabilitation exercises. The sensors integrate multiple sensing capabilities (motion tracking, force measurement, position sensing) into a single device that patients wear comfortably, eliminating the need for separate specialized equipment and improving ease of operation while maintaining treatment plan accuracy through comprehensive kinematics data collection.
Solution Approach 2:
The system enables patients to actively participate in their own treatment by performing prehabilitation exercises with the wearable sensors, which automatically collect and transmit data without requiring constant medical supervision. The sensors provide real-time feedback to patients about their performance, allowing them to self-monitor and adjust their prehabilitation routines. This self-service approach improves patient compliance and ease of operation while ensuring accurate treatment plan development through consistent data collection.
