Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices for fluorescent materials within the body, such as AGEs, face instability in fluorescence intensity due to insufficient fixation of the measurement target region, leading to unreliable results.
Innovation Solution
A measuring device with a placing portion, interposing portion, emitting portion, light-receiving portion, and fixing force supply portion that stabilizes the relative positional relationship between the measurement target region and the light-receiving portion, using a spring-type hinge to apply a consistent force, ensuring the distance between blood vessels and the light-receiving portion remains constant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the measurement target region is not fixed, then the device structure is simple, but the fluorescence intensity becomes unstable and measurement reliability deteriorates
Solution Approach 1:
The device is divided into distinct functional modules: placing portion for positioning the measurement target, interposing portion for applying fixation force, emitting portion for light source, and light-receiving portion for detection. This segmentation allows each module to perform its specific function while maintaining overall system reliability without excessive complexity
Solution Approach 2:
The interposing portion acts as an intermediary between the placing portion and the measurement target region, applying fixation force through a hinge mechanism. This intermediary structure enables stable fixation of the measurement target without requiring direct rigid connection, thus maintaining measurement reliability while keeping the device structure manageable
2Measurement precision
If the measurement target region is loosely placed, then the ease of operation is high, but the relative positional relationship becomes unstable and measurement precision deteriorates
Solution Approach 1:
The hinge mechanism in the interposing portion provides dynamic adjustment capability, allowing the measurement target to be easily placed and removed while maintaining stable fixation during measurement. The hinge can rotate to accommodate different positions but maintains consistent fixation force, thus improving measurement precision without significantly compromising ease of operation
Solution Approach 2:
The fixation force applied by the interposing portion can be adjusted by changing the hinge angle or spring tension, allowing optimization between measurement precision and ease of operation. By adjusting these parameters, the device can achieve stable relative positional relationship while maintaining user-friendly operation
3Measurement precision
If the distance between blood vessels and light-receiving portion varies, then the device structure is flexible, but the fluorescence intensity becomes unstable and measurement precision deteriorates
Solution Approach 1:
The hinge mechanism is designed to maintain a constant distance between the light-receiving portion and the measurement target region regardless of the hinge angle. This equipotential design ensures that the measurement conditions remain consistent during operation, improving measurement precision without requiring overly complex active control mechanisms
Solution Approach 2:
The hinge mechanism uses flexible connections that can rotate while maintaining constant distance constraints. This flexible yet constrained design allows the device to adapt to different measurement scenarios while ensuring consistent distance between critical components, achieving measurement precision without excessive structural complexity
