Multi-Component Cover for Multi-Camera Endoscope Tip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopes face challenges with a limited field of view and complex packing and assembly of components in the tip section, leading to damage during assembly and difficulties in sealing, particularly due to the intricate environment they operate in.
Innovation Solution
A multi-component cover system for the tip section of a multi-camera endoscope, featuring a main component and removable window components that cover and seal the internal elements, allowing access without removing the main component, and are designed to align precisely with cameras and illuminators to prevent damage and enhance sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single integrated cover is used for the tip section, then sealing is simplified, but access to internal components requires complete disassembly and increases risk of damage
Solution Approach 1:
The cover is divided into a main body portion and a separate window component. The window component can be independently removed to access internal components like cameras and illuminators, while the main body remains sealed and attached. This segmentation allows partial access without complete disassembly, reducing damage risk while maintaining sealing integrity.
2Adaptability or versatility
If multiple viewing elements are added to broaden field of view, then imaging capability is improved, but packing complexity and assembly difficulty increase
Solution Approach 1:
The cover structure is segmented into modular sections that can accommodate multiple viewing elements (front-facing and side-facing cameras). Each viewing element has its own designated space and access point through the window component, allowing independent positioning and assembly without increasing overall complexity.
Solution Approach 2:
The window component serves multiple functions: it provides access to cameras, illuminators, and other internal components through a single removable element. This multi-functional design simplifies the overall structure despite containing multiple viewing elements, as one window component replaces what would otherwise require multiple separate access points.
3Volume of moving object
If electronic components are densely packed to reduce endoscope size, then miniaturization is achieved, but assembly damage risk increases
Solution Approach 1:
The segmented cover design allows electronic components to be densely packed in the tip section while providing a protective barrier. The window component can be removed to access and replace components if needed, reducing the risk that dense packing leads to irreversible damage during assembly or maintenance.
Solution Approach 2:
The cover structure itself acts as a protective cushioning element that shields densely packed electronic components from external impacts and assembly forces. By providing this protective layer beforehand, the design mitigates the increased vulnerability that comes with miniaturization and dense component packing.

AI summary
A multi-camera endoscope includes a the tip section comprising: a front looking camera and a front discrete illuminator to essentially illuminate the field of view of said front looking camera; a right side looking camera and a right discrete illuminator to essentially illuminate the field of view of said right side looking camera; a left side looking camera and a left discrete illuminator to essentially illuminate the field of view of said left side looking camera; and a multi-component cover configured to cover and seal said tip section such as to essentially prevent entry of fluids from the environment of said endoscope to inner parts of said tip section. The tip cover includes removable or repositionable window components which provide access to internal components of the tip for repair or removal, without removing the main tip cover.
