Pipe Fitting Sleeve Structure for Variable Caliper Crimp Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pipe fitting connection devices cannot universally match all types of calipers due to varying caliper tooth heights, leading to inconsistent indentation and compression, which compromises the sealing performance between the pipe fitting connection device and the pipe.
Innovation Solution
A pipe fitting connection device with a core body and connecting body, featuring a positioning sleeve with matching portions and positioning ribs forming a clamping groove, along with a mounting groove for a sealing ring and anti-slip wall, allowing for adaptable compression and sealing regardless of caliper tooth height, using a caliper to compress and deform the pipe for reliable sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional pipe fitting connection devices are used with various types of calipers, then the device can be mounted on different caliper types, but the sealing performance is compromised due to inconsistent caliper tooth heights causing varying indentation and compression
Solution Approach 1:
The clamping groove is designed with a bottom wall that can be compressed, and positioning ribs that can be deformed. When calipers with different tooth heights are applied, the bottom wall and positioning ribs adjust their compression degree accordingly, ensuring consistent sealing performance across various caliper types while maintaining adaptability to different tooth heights
Solution Approach 2:
The positioning ribs are designed as movable elements that can be compressed between the caliper tooth and the bottom wall of the clamping groove. This dynamic structure allows the system to adapt to different caliper tooth heights while maintaining reliable sealing through controlled deformation of the positioning ribs and bottom wall
2Adaptability or versatility
If calipers with different tooth heights are used to crimp the pipe, then various caliper types can be utilized, but the number and amount of indentations become inconsistent, compromising sealing reliability
Solution Approach 1:
The bottom wall of the clamping groove and the positioning ribs are designed to undergo controlled deformation based on the applied compression force. This allows the system to accommodate different caliper tooth heights while maintaining consistent indentation quality and compression amount, ensuring uniform sealing performance regardless of the specific caliper type used
