Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physiological information sensors are attached without guidance, then the operation process is simple and fast, but the attachment position accuracy deteriorates leading to wrong sensor placement
Solution Approach 1:
The system displays attachment position information on the display unit before the medical worker attaches the sensor. This preliminary display of guidance information allows the user to understand the correct attachment position in advance, improving attachment accuracy without adding complex operational steps during the actual attachment process
Solution Approach 2:
The display unit serves as an intermediary between the control unit and the medical worker. It visually presents attachment position information and sensor data, mediating the interaction and providing guidance without requiring complex manual procedures or additional hardware components
2Measurement precision
If physiological information sensors are attached without verification, then the process is quick, but the measurement precision deteriorates due to incorrect attachment
Solution Approach 1:
The system displays information related to the physiological information data acquired from the sensor on the display unit. This feedback mechanism allows the medical worker to verify whether the sensor is correctly attached by observing the quality and plausibility of the measured data, ensuring measurement precision while maintaining efficient workflow
Solution Approach 2:
Attachment position information is displayed before the sensor is attached, providing preliminary guidance that prevents incorrect attachment. This proactive approach reduces the need for time-consuming verification and re-attachment, optimizing the balance between speed and accuracy
3Ease of operation
If attachment position information is not displayed, then the device operation is simple, but the usability deteriorates for inexperienced medical workers
Solution Approach 1:
The control unit causes the display unit to display attachment position information before the sensor attachment process begins. This preliminary guidance is provided automatically without requiring the user to search for information or understand complex procedures, improving ease of operation for inexperienced users while maintaining simple device architecture
Solution Approach 2:
The information display is segmented into different stages: attachment position information is displayed first, then information related to physiological data is displayed after sensor attachment. This segmentation presents information in a logical sequence, reducing cognitive load and improving usability without overwhelming the user with complex simultaneous displays
Data Source
AI summary
A physiological information processing apparatus comprising: a processor; and a memory that stores a computer-readable instruction that when executed by the processor, causes the physiological information processing apparatus to perform operations comprising: displaying on a display unit, first attachment position information representing a position where a first physiological information sensor is attached; acquiring first physiological information data of a subject from the first physiological information sensor; and displaying, on the display unit, information relevant to the first physiological information data. The physiological information processing apparatus displays the first attachment position information on the display unit before displaying the information relevant to the first physiological information data on the display unit.
