Pipe Connection Diffusion Part for Uniform Adhesive Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting pipe elements with an enlarged socket suffer from uneven adhesive distribution and risk of gasket ejection or excess adhesive flowing into the pipe, leading to unsatisfactory connections.
Innovation Solution
A device with a diffusion part that directs injected assembly fluid circumferentially and axially to ensure uniform distribution within the connection space between the socket and the pipe element, using a tilted or curved deflector surface and secondary diffusion channels to actively direct the fluid into the connection area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If injection pressure is increased to fill the annular space, then adhesive distribution improves, but gasket ejection or excess adhesive flow occurs
Solution Approach 1:
The annular space is segmented into multiple injection zones through several injection openings distributed around the circumference. This allows controlled adhesive introduction at multiple locations simultaneously, ensuring uniform distribution without requiring excessive pressure that would cause gasket ejection or adhesive overflow.
Solution Approach 2:
The injection system provides localized adhesive introduction at specific circumferential positions through multiple injection openings. Each opening delivers adhesive to a specific local region of the annular space, creating locally optimized adhesive distribution that collectively achieves uniform coverage without global pressure increases.
2Device complexity
If conventional injection method is used, then device complexity remains low, but adhesive distribution becomes non-uniform
Solution Approach 1:
The injection system is segmented into multiple simple injection openings distributed around the circumference rather than a single complex injection point. This segmentation approach maintains relative simplicity in each individual opening while achieving uniform adhesive distribution through the combined effect of multiple openings.
Solution Approach 2:
Multiple simple injection openings are merged in their functional effect to achieve the complex outcome of uniform adhesive distribution. Each opening is simple in structure, but their combined action across the circumferential direction creates the desired uniform adhesive layer in the annular space.
