Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope shape display technologies do not effectively convey the reliability of the shape information displayed on the screen, leading to confusion for operators, especially when detection accuracy changes or sensors fail.
Innovation Solution
An endoscope shape display device that calculates the reliability of the shape estimation and displays it in a fade-out mode, using equations that consider sensor accuracy, shape change degree, and elapsed time to provide visual feedback on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If color-coded display is used to indicate detection range status, then operator awareness of effective detection range is improved, but reliability information of the displayed shape is not provided
Solution Approach 1:
The endoscope shape display is segmented into multiple regions based on reliability levels. The display area is divided into a first area (high reliability) and a second area (low reliability), allowing operators to visually distinguish between reliable and unreliable shape information without losing overall context.
Solution Approach 2:
Different visual characteristics are applied to different regions of the display based on their reliability levels. The first area uses display characteristics that indicate high reliability, while the second area uses characteristics that indicate low reliability, providing localized quality information throughout the display.
2Measurement precision
If entire endoscope shape is displayed continuously, then visual continuity is maintained, but unreliable shape information may mislead operators
Solution Approach 1:
Different visual characteristics are applied to different regions of the display based on their reliability levels. The first area uses display characteristics that indicate high reliability, while the second area uses characteristics that indicate low reliability, providing localized quality information throughout the display.
Solution Approach 2:
The system provides continuous feedback to operators about the reliability of shape information through visual characteristics. This feedback mechanism helps operators understand which parts of the displayed shape are reliable and which require caution, preventing misleading interpretations.
3Illumination intensity
If color changes are used to indicate detection status, then detection range visibility is improved, but distinction between detection status and reliability is lost
Solution Approach 1:
The display is segmented into multiple areas with different visual characteristics. By dividing the display into a first area and a second area with distinct characteristics, the system can simultaneously convey both detection status and reliability information without confusion.
Solution Approach 2:
Different visual characteristics are applied to different regions of the display based on their reliability levels. The first area uses display characteristics that indicate high reliability, while the second area uses characteristics that indicate low reliability, providing localized quality information throughout the display.
