Anchoring Ring Access for Damage-Free Fluid Connector Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid connection devices damage circuit elements during extraction, leading to reduced anchoring performance and potential fluid pollution due to material shavings.
Innovation Solution
A connection device with a hooking ring and insert, where the ring's teeth are inclined to facilitate easy extraction and a pin is used to secure the ring for rotation, preventing damage and pollution by creating a screw thread-like motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hooking ring is used to anchor the insert in the well, then the insert can be securely fixed, but the ring damages the well surface during extraction
Solution Approach 1:
The patent introduces a pin as an intermediary element that temporarily connects the hooking ring to the insert during extraction. This pin allows the ring to be guided and controlled during the removal process, preventing it from rubbing directly against and damaging the well surface while still maintaining the anchoring function during normal operation
Solution Approach 2:
The patent employs preliminary action by preparing the extraction process in advance through the use of a notched tool that engages with the hooking ring's notch. This tool is inserted before extraction begins, establishing a controlled connection that prevents damage during the subsequent removal operation
2Ease of operation
If the hooking ring is extracted by unscrewing the insert, then the insert can be removed, but material shavings pollute the fluid
Solution Approach 1:
The notched tool acts as an intermediary that engages with the hooking ring's notch to provide a controlled extraction path. This prevents the ring from tearing against the well surface and generating harmful shavings that would pollute the fluid
Solution Approach 2:
The patent replaces the traditional unscrewing mechanical action with a sliding motion along an inclined plane. The teeth on the hooking ring engage with the inclined surface of the notched tool, converting the extraction motion from rotational unscrewing to linear sliding, which eliminates shavings generation
3Ease of operation
If the teeth of the hooking ring are inclined to facilitate extraction, then the ring slides more easily, but the structure becomes more complex
Solution Approach 1:
The hooking ring is segmented into distinct functional elements: the anchoring teeth with inclined faces for engagement, the body of the ring for structural integrity, and the notch for tool engagement. This segmentation allows each part to perform its specific function efficiently while keeping the overall design relatively simple
