Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the probe unit and apparatus main body unit are separated and connected with a long signal cable, then the monitor can be used in hospital settings, but the size and mass increase and handleability deteriorates in emergency sites
Solution Approach 1:
The patent integrates the sensor unit and apparatus main body unit into a single compact monitor device, eliminating the need for separate units and long connecting cables. This merging reduces the overall size and mass while maintaining measurement functionality, making the device suitable for portable emergency use without compromising measurement reliability
2Reliability
If the probe unit and apparatus main body unit are separated, then signal transmission can be maintained, but the device complexity increases and portability decreases
Solution Approach 1:
The patent combines the sensor unit and main body unit into an integrated structure, eliminating complex cable connections and multiple separate components. The integration simplifies the overall device structure while maintaining signal transmission capability through internal wiring, significantly improving portability and reducing structural complexity
3Ease of operation
If the monitor is made compact and portable, then handleability improves in emergency sites, but the measurement precision may deteriorate
Solution Approach 1:
The integration of sensor and processing units allows for optimized signal processing algorithms and real-time calibration capabilities within the compact device, maintaining measurement precision despite the reduced size
4Reliability
If a long signal cable is used to connect separate units, then signal transmission is maintained, but the device becomes cumbersome and space-consuming
Solution Approach 1:
The patent eliminates the need for long external signal cables by integrating the sensor unit and main body unit into a single compact device with internal wiring, dramatically reducing the device volume and eliminating cable management requirements while maintaining reliable signal transmission

AI summary
A non-invasive monitor for measuring regional saturation of oxygen includes a sensor unit containing a printed circuit board on which a light emitting unit and a light receiving unit are mounted; a main body unit; a sensor holder for holding the sensor unit while the light emitting unit and the light receiving unit are disposed in an aperture portion; a sensor pressing board; a connecting unit for electrically connecting the sensor unit and the main body unit; and a headband. The light emitting unit and the light receiving unit are disposed such that a light emitting surface and a light receiving surface face the forehead-side, and a part or the whole of the forehead-side surface of the sensor unit is on the same surface as the forehead-side surface of the sensor holder or protrudes from the forehead-side surface of the sensor holder toward the forehead-side.
