Solution Overview

Problem

The existing process of connecting two fluid conduits is complex, requiring valves to be closed and then opened sequentially, making it a cumbersome operation.

Innovation Solution

A fluid conduit structure featuring a first and second conduit with movable blocking bodies that allow for quick connection and separation by a simple plugging and pulling action, where the blocking bodies are not perpendicular to the conduction direction, enabling efficient fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional valve closing and opening process is used to connect two conduits, then fluid flow control is reliable, but the operation process becomes complex and time-consuming

Engineering Contradiction:

Improveconduit connection operationVSAvoidconnection time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent extracts the valve closing/opening operations from the conduit connection process. By using blocking bodies that are integrated into the conduit structure itself, the connection can be made by simply plugging and pulling the conduits together, eliminating the need for separate valve operations and significantly simplifying the connection process

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The blocking bodies are pre-positioned within the conduit structures before connection. When the conduits are plugged together, the blocking bodies are already in place to automatically seal the fluid passages, eliminating the need for time-consuming valve operations during the connection process

Inventive Principle:

Principle #10Preliminary action

2Reliability

If blocking bodies are positioned perpendicular to conduction direction, then sealing is effective, but fluid flow resistance increases

Engineering Contradiction:

Improvesealing effectivenessVSAvoidfluid flow resistance

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent employs asymmetric positioning of the blocking bodies relative to the conduction direction. The blocking bodies are angled or positioned non-perpendicularly to create an asymmetric flow path that maintains effective sealing while reducing turbulence and flow resistance compared to perpendicular positioning

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The blocking bodies feature curved or rounded surfaces instead of sharp perpendicular edges. This curvature allows fluid to flow smoothly around the blocking bodies, maintaining sealing effectiveness while minimizing flow resistance and preventing turbulence

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A fluid conduit structure includes a first conduit, a second conduit, a first blocking body, and a second blocking body. The first conduit and the second conduit include a first body portion and a second body portion extending along a conduction direction. The first blocking body is movably assembled to the first body portion and is used to close the first conduit. The second blocking body is provided in the second body portion and is used to close the second conduit. The second blocking body is used to enter the first body portion to push against the first blocking body, and when the second blocking body pushes against the first blocking body, the first blocking body and the second blocking body open the first conduit and the second conduit to generate a flow line in the first body part.
