Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical blood content sensors require contact with tissue for accurate detection, but gaps between sensors and tissue lead to reduced light interaction, resulting in inaccurate abnormality detection.

Incorporating contact detectors with blood content sensors to ensure accurate data collection and using multiple sensors positioned on a probe or endoscope to enhance detection accuracy by providing simultaneous data for statistical processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact detectors are added to ensure sensor-tissue contact, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The contact detector is activated before the blood content sensor to pre-establish and verify proper sensor-tissue contact. This preliminary action ensures that subsequent measurements are taken under optimal conditions, preventing inaccurate readings before they occur.
Solution Approach 2:
The contact detector provides real-time feedback signals to the control system, which then adjusts or validates the operation of the blood content sensor accordingly. This feedback mechanism ensures that measurements are only taken when proper contact is confirmed, maintaining high measurement precision.
2Measurement precision
If multiple blood content sensors are used to improve detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detection system is divided into multiple independent sensor units, each capable of detecting blood content at its specific location. This segmentation allows for distributed measurement across the tissue surface, improving overall detection accuracy while maintaining modular simplicity in each sensor unit.
Solution Approach 2:
Data from multiple blood content sensors are merged and processed together to provide a comprehensive view of tissue abnormality. The control system integrates signals from all sensors to generate a unified detection result, enhancing measurement precision through combined information.
3Measurement precision
If sensors remain in continuous contact with tissue, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
Instead of requiring continuous contact, the system uses periodic contact detection where the contact detector is activated at specific intervals to verify sensor-tissue contact. This allows the probe to be manipulated more freely between measurement points while ensuring accuracy when measurements are taken.
Solution Approach 2:
The system dynamically adjusts its operation based on real-time contact status. When contact is detected, measurements are taken; when contact is lost, the system pauses measurement functions. This dynamic adaptation maintains measurement precision while allowing greater operational flexibility.
