Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the catheter is removed from the hoop for light intensity measurement, then the measurement can be performed, but the cleanliness of the catheter is compromised
Solution Approach 1:
The patent applies nesting by placing the light receiving part inside the hoop structure, allowing the measurement device to be nested within the existing catheter containment structure. This enables light intensity measurement while the catheter remains protected inside the hoop, eliminating the need to remove the catheter for measurement and thus preventing contamination.
Solution Approach 2:
The patent introduces a transmission window as an intermediary element that allows light to pass through while maintaining the physical barrier of the hoop. The transmission window mediates between the need for light intensity measurement and the need to maintain catheter cleanliness, enabling optical measurement without compromising the protective enclosure.
2Measurement precision
If the catheter is removed from the hoop for measurement, then light intensity can be measured, but the process complexity increases
Solution Approach 1:
The patent merges the light intensity measurement function with the existing hoop structure by integrating the light receiving part into the hoop. This combination eliminates the need for separate removal and measurement steps, simplifying the overall process while maintaining measurement capability.
Solution Approach 2:
The patent enables the hoop structure to serve dual purposes: both protecting the catheter and facilitating light intensity measurement. The hoop with its transmission window performs both containment and measurement support functions, eliminating the need for additional external measurement equipment or complex procedural steps.
3Object-affected harmful factors
If the hoop structure is designed to accommodate measurement, then cleanliness is maintained, but the device structure becomes more complex
Solution Approach 1:
The patent applies local quality by adding the transmission window only at the specific location where light intensity measurement is needed, rather than making the entire hoop structure complex. The transmission window is localized to the tip end portion, maintaining simplicity in other areas while enabling measurement functionality where required.

AI summary
A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part. The mounting part defines a position of a tubular hoop, which accommodates the catheter, with respect to the light receiving part. In a state in which the position of the hoop is defined by the mounting part, the light measurement device obtains the intensity of the laser light by inputting the laser light to the light receiving part.
