Drip Irrigation Pipe Wall Structure for Localized Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Relative thin-walled irrigation pipes are susceptible to damage due to wear and tear, especially at areas of bonding and connection to drip emitters, which can lead to reduced durability and efficiency in irrigation systems.
Innovation Solution
The irrigation pipe design incorporates a base portion with a constant thickness and a series of bulge members that increase the pipe wall thickness radially, forming valleys between adjacent bulges. These bulge members can be ribbed and extend along the pipe axis on both inner and outer faces, providing additional strength and protection to vulnerable areas such as the drip emitter locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If thin-walled irrigation pipes are used, then cost and flexibility are improved, but durability and resistance to wear and tear deteriorate
Solution Approach 1:
The pipe wall is designed with non-uniform thickness through the incorporation of bulge members that create localized thickened areas. These bulge members are positioned at specific locations where additional strength is needed, such as at emitter connection points and along sections susceptible to wear and tear during installation and use. The base portion maintains a thinner wall profile for cost-effectiveness and flexibility, while the bulge members provide localized reinforcement to enhance overall durability.
2Ease of operation
If thin-walled irrigation pipes are used, then ease of installation and flexibility are improved, but resistance to damage during installation and use deteriorates
Solution Approach 1:
The pipe incorporates bulge members that create localized thickened regions at positions where the pipe is most vulnerable to damage during installation and use. These bulge members are strategically positioned to protect against wear and tear while maintaining the overall thin-walled structure that provides flexibility and ease of installation. The valleys between adjacent bulge members allow the pipe to maintain its flexibility, while the bulge members themselves provide enhanced resistance to external forces and damage.
3Ease of manufacture
If uniform wall thickness is used, then manufacturing simplicity is improved, but localized strength at vulnerable areas deteriorates
Solution Approach 1:
The pipe manufacturing process incorporates bulge members that create localized variations in wall thickness. These bulge members are formed during the extrusion process, allowing for relatively simple manufacturing while achieving non-uniform wall thickness. The bulge members provide enhanced strength at specific vulnerable locations such as emitter connection areas, while the base portion maintains a standard thickness for manufacturing efficiency. This approach enables localized reinforcement without requiring complex multi-step manufacturing processes.

AI summary
The present invention relates to a drip irrigation pipe having pipe wall comprising a base portion and a strip located on at least a portion of an inner side of the base portion facing into the pipe. The pipe further comprises drip emitters (20) attached to the strip. The material of the strip is different than the material of the base portion.
