Problem
Conventional rigid endoscopes face challenges in assembly due to the use of optical fibers for light transmission, leading to poor illumination and light leakage, which complicates the manufacturing process and increases costs.
Innovation Solution
An endoscopic image capturing assembly is designed with a light emitting component positioned closer to the tip, eliminating the need for long optical fibers, ensuring better illumination, preventing light leakage, and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fiber is used to transmit light from a light emitting component far behind an image sensor, then light leakage is prevented, but assembly difficulty increases and illumination quality deteriorates
Solution Approach 1:
The patent extracts the light emitting component from its traditional position far behind the image sensor and relocates it to a position closer to the image sensor. This extraction eliminates the need for long optical fibers while maintaining light leakage prevention through the holder's light-shielding structure, thereby reducing assembly complexity
Solution Approach 2:
The holder serves as an intermediary structure that integrates both the light emitting component and the image sensor in close proximity. The holder's light-shielding walls act as a mediator to prevent light leakage directly from the light emitting component to the image sensor, eliminating the need for long optical fibers while maintaining reliable light isolation
2Reliability
If optical fiber is used to transmit light over a long distance, then light leakage is prevented, but illumination intensity decreases
Solution Approach 1:
The patent extracts the light emitting component from its traditional distant position and relocates it close to the image sensor. This eliminates long optical fiber transmission paths that cause illumination degradation, while the holder's light-shielding structure maintains effective light leakage prevention
Solution Approach 2:
The patent applies local light shielding through the holder's walls specifically at the location where the light emitting component is positioned. This localized approach prevents light leakage in the critical area near the image sensor without requiring long-distance optical fiber transmission, thereby maintaining high illumination intensity
3Reliability
If optical fiber is used for light transmission, then light leakage is prevented, but manufacturing cost increases
Solution Approach 1:
The patent extracts the light emitting component from its traditional position and relocates it close to the image sensor, eliminating the need for long optical fibers. This simplifies the manufacturing process and reduces costs while the holder's light-shielding structure maintains effective light leakage prevention
Solution Approach 2:
The patent merges the light emitting component and image sensor into a closely integrated arrangement within the holder. This combination eliminates the need for separate long optical fiber assemblies, reducing manufacturing complexity and cost while maintaining light leakage prevention through the integrated holder structure
