Solution Overview
Problem
Existing refrigeration systems face challenges in balancing assembling efficiency and sealing performance when connecting flexible and rigid pipes, with existing connection structures either being simple and ineffective or complex and difficult to operate.
Innovation Solution
A pipe connection mechanism featuring a joint pipe with opposing pipe parts and a sleeve that supports the flexible pipe in an interference manner, ensuring sealing through external pressure, with anti-slip structures and limiting bosses for enhanced fit and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a simple connection structure is used between flexible pipe and rigid pipe, then assembling efficiency is improved, but sealing performance deteriorates
Solution Approach 1:
The connection structure is divided into distinct functional segments: the joint pipe body, the sleeve, and the anti-slip structures. This segmentation allows each component to perform its specific function optimally - the joint pipe provides structural connection, the sleeve ensures sealing through interference fit, and the anti-slip structures prevent assembly errors, thereby achieving both efficient assembly and reliable sealing.
Solution Approach 2:
The sleeve acts as an intermediary component between the joint pipe and the flexible pipe. It provides the interference fit sealing mechanism while the anti-slip structures on the joint pipe serve as intermediaries to guide and secure the flexible pipe during assembly, enabling both simple operation and effective sealing.
2Reliability
If a complex connection structure is used between flexible pipe and rigid pipe, then sealing performance is improved, but assembling efficiency deteriorates
Solution Approach 1:
The sealing function is extracted as a separate feature through the sleeve component, which provides interference fit sealing independently from the main connection structure. This allows the sealing mechanism to be optimized without complicating the overall assembly process, as the sleeve can be easily installed alongside other components.
Solution Approach 2:
The anti-slip structures are pre-formed on the joint pipe, creating preliminary guiding features that automatically align and secure the flexible pipe during assembly. This preliminary action prevents assembly errors and ensures proper positioning before the final sealing connection is made, streamlining the entire assembly process.
3Reliability
If an interference fit connection is used between joint pipe and flexible pipe, then sealing performance is improved, but assembling difficulty increases
Solution Approach 1:
The anti-slip structures on the joint pipe provide self-guiding and self-securing functionality during assembly. As the flexible pipe is inserted, the anti-slip structures automatically engage to prevent slippage and ensure proper positioning, allowing the interference fit connection to be made without requiring additional tools or complex assembly procedures.
