Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple illumination modes are provided to optimize imaging for different diagnostic purposes, then the adaptability and diagnostic capability are improved, but the device complexity and control difficulty increase
Solution Approach 1:
The illumination source is designed to provide multiple illumination modes (first illumination mode and second illumination mode) with different spectral characteristics using a single device. The controller automatically selects and switches between modes based on diagnostic needs, making the illumination system multi-functional without requiring separate illumination devices for each mode.
Solution Approach 2:
The illumination system employs dynamic control where the controller automatically switches between different illumination modes based on real-time diagnostic requirements. The controller determines when to use the first illumination mode versus the second illumination mode, enabling the system to adapt dynamically to changing observation conditions and diagnostic needs.
2Measurement precision
If illumination properties are changed to optimize support information generation, then the measurement precision and diagnostic accuracy are improved, but the loss of time for switching and adjustment increases
Solution Approach 1:
The system pre-configures multiple illumination modes with optimized spectral characteristics for different diagnostic purposes. The controller has predetermined criteria and algorithms to automatically determine which illumination mode to use based on the observation conditions, eliminating the need for manual adjustment and reducing decision-making time.
Solution Approach 2:
The controller automatically monitors observation conditions and support information generation quality, then feedback-controls the illumination mode selection. When the current illumination mode no longer provides optimal support information, the controller automatically switches to a more appropriate mode, ensuring continuous optimization without manual intervention.
3Productivity
If time-division emission of display and support illumination light is implemented, then the productivity and information generation efficiency are improved, but the illumination intensity for each mode is reduced
Solution Approach 1:
The illumination system uses time-division multiplexing to alternately emit display illumination light and support illumination light in periodic cycles. During each cycle, the display illumination light is emitted for a predetermined period to capture display images, then the support illumination light is emitted for a predetermined period to capture support images, enabling efficient sequential operation.
Solution Approach 2:
The controller dynamically adjusts emission parameters including the timing, duration, and intensity of display versus support illumination light based on diagnostic priorities. The controller can modify the duty cycle and emission timing to optimize the balance between display image quality and support information generation efficiency for different diagnostic scenarios.
Data Source
AI summary
An endoscope apparatus includes an illuminating device and a processor. The illuminating device emits display illumination light and support illumination light in a time-division manner. The processor generates a display image based on an image signal acquired when the display illumination light is emitted, and support information based on an image signal acquired when the support illumination light is emitted. The processor generates first support information when an illumination property is a first illumination property, superimposes first display content based on the first support information on the display image, switches the illumination property of the support illumination light to a second illumination property upon determination that the first support information satisfies a predetermined condition, generates second support information when the illumination property is the second illumination property, and superimposes second display content based on the second support information on the display image.
