Endoscope Optical Adapter Anti-Slip Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction in diameter of endoscope optical adapters compromises the strength of the anti-slip portion, leading to potential breakage and detachment when external forces are applied, as the anti-slip portion becomes thinner and less robust compared to other parts.
Innovation Solution
The design incorporates a cylindrical body with an anti-slip portion featuring a plurality of recesses arranged circumferentially, positioned to avoid overlap with the thinner section when engaged, ensuring the anti-slip portion is thicker and more robust, preventing breakage and detachment by distributing external forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the diameter of the optical adapter is reduced to achieve a thinner design, then the overall size is reduced, but the anti-slip portion becomes thinner and its strength is reduced
Solution Approach 1:
The patent applies local quality by creating a localized thickened portion at the anti-slip area of the connection ring. While the overall diameter of the optical adapter is reduced, the anti-slip portion specifically maintains increased thickness through this localized structural modification, allowing it to resist external forces without requiring the entire adapter to be larger.
2Volume of moving object
If the anti-slip portion is made thinner to reduce the diameter of the optical adapter, then the overall size is reduced, but the anti-slip portion becomes more prone to breakage when external forces are applied
Solution Approach 1:
The thickened portion is specifically positioned at the anti-slip area to locally enhance reliability. This localized structural reinforcement ensures that the anti-slip portion can withstand external forces and resist breakage without compromising the overall compact design of the optical adapter.
Solution Approach 2:
The thickened portion acts as a preemptive reinforcement that cushions the anti-slip portion against potential breakage before external forces are applied. By designing this structural feature in advance, the patent ensures that the connection ring can handle unexpected external forces without failing.
3Volume of moving object
If the anti-slip portion is positioned to overlap with the thinner section, then the diameter can be reduced, but the anti-slip portion becomes weaker and may detach
Solution Approach 1:
The patent positions the thickened portion specifically at the anti-slip area to ensure that this critical functional zone maintains high structural integrity. By concentrating material where it is most needed for stability, the design prevents detachment while maintaining overall compactness.
Solution Approach 2:
The patent addresses the positioning issue by considering the longitudinal dimension in addition to the radial dimension. The thickened portion is strategically positioned in the longitudinal direction to ensure it does not overlap with the thinner section, thereby maintaining attachment stability while preserving the reduced diameter design.

AI summary
An adapter for an endoscope, the adapter including: a cylindrical body having an internal portion formed on the cylindrical body, the internal portion configured to matingly engage with each of distal and proximal external portions provided on a tip of the endoscope, the distal and proximal external portions being separated in a longitudinal direction of the cylindrical body by a portion of the tip that does not engage the internal portion; and wherein the cylindrical body further having an anti-slip portion formed on an exterior of the cylindrical body, the anti-slip portion having a plurality of recesses arranged circumferentially on the exterior, a position of the anti-slip portion in the longitudinal direction being set such that a position of the proximal external portion in the longitudinal direction does not overlap with the longitudinal position of the anti slip portion where the proximal external portion is engaged with the internal portion.
