Endoscopic Inspection System with Switchable Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic inspection systems often fail to detect abnormal regions under white light mode, leading to potential overlooking of high-risk abnormalities, as users may not switch to narrow band imaging (NBI) mode unless an abnormality is explicitly identified.
Innovation Solution
An endoscopic inspection system that alternates between white light and NBI light, using a switchable light source, endoscope, processor, and display to simultaneously acquire and analyze image data from both modes, determining the presence of abnormal regions and providing alert signals or probability data for immediate user action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system operates in white light mode only, then the device complexity is reduced and operation is simpler, but the ability to detect abnormal regions is insufficient
Solution Approach 1:
The light source device dynamically switches between white light and NBI illumination modes based on detection needs. The system transitions from a static single-mode operation to a dynamic multi-mode operation, allowing the inspector to adapt the illumination type according to the suspected abnormality characteristics, thereby improving detection reliability without permanently increasing device complexity
Solution Approach 2:
The system implements periodic switching between white light mode and NBI mode during the inspection process. The controller alternates between different illumination modes at appropriate intervals to capture images under both lighting conditions, enabling comprehensive abnormality detection while maintaining manageable system complexity through structured operation sequences
2Productivity
If the user manually switches between white light and NBI modes, then the device complexity remains low, but the inspection time increases and productivity decreases
Solution Approach 1:
The system performs preliminary automated detection using white light mode to identify potential abnormal regions before switching to NBI mode for detailed analysis. This preliminary action filters out normal areas, allowing the system to focus NBI imaging only on suspicious regions, thereby reducing the total inspection time and improving productivity while minimizing mode-switching delays
Solution Approach 2:
The controller maintains continuous inspection operation by seamlessly switching between white light and NBI modes without interrupting the overall inspection flow. The system ensures that image acquisition continues uninterrupted across mode transitions, eliminating idle time and maintaining productive inspection rhythm throughout the entire inspection process
3Measurement precision
If the system acquires image data under both white light and NBI modes simultaneously, then the measurement precision of abnormal region detection is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system applies partial action by acquiring NBI mode image data only for regions identified as potentially abnormal through preliminary white light detection, rather than continuously capturing both modes for the entire inspection area. This selective NBI imaging reduces overall energy consumption while maintaining high measurement precision for the critical abnormal regions that require detailed analysis
