Pipe Coupling Assembly With Groove-Based Seal Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe couplings face challenges in work efficiency due to the need for multiple segments to be fastened together, and the increased length of sealing members leads to fluid leakage when deformed during assembly.
Innovation Solution
A coupling assembly with a body portion, locking portion, and fastening portion, featuring a receiving groove to prevent sealing member deformation and interference prevention grooves, ensuring stable connection and fluid integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radius of curvature of the arcuate surface of the segment is formed to be greater than the radius of the outer peripheral surface of the pipe to improve workability, then the segments can be moved in the axial direction while provisionally assembled, but the second sealing member deforms in the peripheral direction when the coupling is fastened, causing fluid leakage
Solution Approach 1:
The patent changes the geometric parameters of the internal space, specifically forming it with a cross-sectional area larger than that of the first sealing member, to accommodate the second sealing member with increased peripheral length without causing deformation during fastening
Solution Approach 2:
The internal space is pre-formed with sufficient cross-sectional area to accommodate the second sealing member before assembly, allowing the sealing member to be properly positioned and preventing deformation during subsequent fastening operations
2Ease of operation
If the second sealing member is made longer in peripheral length to move smoothly along the coupling, then it can be installed while the coupling is provisionally assembled, but it deforms in the peripheral direction when fastened, causing fluid leakage
Solution Approach 1:
The patent increases the peripheral length of the second sealing member to improve installation ease, and simultaneously increases the cross-sectional area of the internal space to accommodate this longer sealing member without deformation during fastening
3Volume of moving object
If the cross-sectional area of the internal space is designed based on the first sealing member size, then the coupling structure is compact, but the second sealing member cannot be properly accommodated when its peripheral length is increased
Solution Approach 1:
The patent increases the cross-sectional area of the internal space to accommodate the second sealing member with increased peripheral length, balancing the need for compact structure with the requirement for proper sealing member accommodation
