Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pulse oximetry sensors are used to ensure compatibility with different monitors from various manufacturers, then compatibility with different monitors is improved, but device complexity and treatment cost increase
Solution Approach 1:
The pulse oximetry sensor is designed with multiple light emitting elements (red, infrared, yellow-green) that can emit different wavelengths of light. By selectively activating different light emitting elements through the adapter, a single sensor can be made compatible with multiple types of monitors from different manufacturers, eliminating the need for multiple specialized sensors.
Solution Approach 2:
An adapter is introduced as an intermediary component between the pulse oximetry sensor and the monitor. The adapter contains multiple wires corresponding to different light emitting elements and can be configured to connect different combinations of these elements to the monitor, enabling compatibility across different monitor types without modifying the sensor itself.
2Adaptability or versatility
If multiple pulse oximetry sensors are prepared for different clinical environments, then adaptability to different monitors is improved, but clinical workload and operation complexity increase
Solution Approach 1:
The sensor with multiple light emitting elements and the configurable adapter enable a single sensor to function across all four clinical environments (operating room, postanesthesia care unit, ICU, and general ward) by adapting to different monitor types, thereby reducing the number of sensors clinical staff need to manage and decreasing operational complexity.
3Reliability
If different pulse oximetry sensors are used for different monitors, then signal compatibility is improved, but treatment cost increases
Solution Approach 1:
By equipping the sensor with multiple light emitting elements capable of emitting different wavelengths (red, infrared, yellow-green) and using an adapter to selectively connect these elements to the monitor, the system achieves signal compatibility across different monitor types while reducing the quantity of sensors needed from four to one.

AI summary
An oximetry probe and an operating method thereof, and an oximetry sensor. The oximetry probe includes an oximetry sensor which includes a detection end and an output end, and an adapter. The detection end includes a photodetector and multiple light-emitting elements connected in series. The output end has multiple output ports. Adjacent output ports are electrically connected to two sides of the corresponding light-emitting element. The adapter has a first adapter end and a second adapter end between which multiple wires are provided. The first adapter end is electrically connected with an input end of the monitor. When the second adapter end is connected to the output end, the wires are electrically connected with the output ports to form closed circuit to enable the light-emitting element to emit light which is received by the photodetector to generate a signal involving blood oxygen saturation to be displayed on the monitor.
