Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate display devices are used for living body optical signals and brain wave signals, then each signal can be displayed independently, but it becomes difficult for specialists to comprehensively observe and diagnose brain functions
Solution Approach 1:
The patent combines the display of living body optical signals and brain wave signals on a single display device, integrating multiple signal types into one unified interface. This allows specialists to comprehensively observe both signal types simultaneously without needing multiple separate display systems, thereby reducing device complexity while preventing information loss.
2Measurement precision
If multiple optical fibers and electrodes are placed separately for precise measurement, then measurement precision is improved, but preparation time becomes lengthy
Solution Approach 1:
The patent integrates multiple optical fibers and electrodes into a single integrated probe device. This unified probe structure allows all measurement components to be attached simultaneously in one operation, eliminating the need for separate placement of each fiber and electrode, thereby maintaining measurement precision while significantly reducing preparation time.
Solution Approach 2:
The probe device is pre-configured with multiple optical fibers and electrodes positioned at predetermined locations before contact with the subject. This preliminary arrangement of measurement components ensures that when the probe is attached, precise measurements are achieved immediately without requiring time-consuming individual placement and adjustment of each component.
3Reliability
If separate probe devices are used for optical measurement and brain wave measurement, then each measurement can be optimized independently, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The patent combines optical measurement components and brain wave measurement components into a single integrated probe device. This unified structure allows both types of measurements to be performed simultaneously through one attachment operation, maintaining the reliability of each measurement type while greatly simplifying the attachment process and improving ease of operation.
