Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infiltration irrigation pipes face blockages due to external soil and negative pressure, and struggle with unstable water flow and uneven infiltration distribution.
Innovation Solution
An anti-blocking drip infiltration pipe strip is designed with a dripper and a shielding layer made of permeable cloth or plastic, sewn along the length direction to prevent blockages and ensure stable water flow, featuring turbulent protrusions and heat-sealing structures for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dripper is directly exposed in the infiltration pipe, then the structure is simple, but the dripper gets blocked by external soil and negative pressure
Solution Approach 1:
A shielding layer made of permeable cloth material is introduced as an intermediary component between the dripper and the external environment. This shielding layer prevents direct contact between the dripper and blocking substances (soil, sediment) while still allowing water to pass through via its permeable structure, thus resolving the contradiction between blockage prevention and structural simplicity
Solution Approach 2:
The shielding layer is constructed from flexible permeable cloth material that can be wrapped around the infiltration pipe. This thin film structure provides protection against blockages while maintaining flexibility and not significantly increasing structural complexity, allowing the system to adapt to different installation conditions
2Reliability
If the shielding layer is made of impermeable material to prevent blockage, then blockage is prevented, but water flow becomes unstable and infiltration uniformity decreases
Solution Approach 1:
The shielding layer is specifically designed using porous permeable cloth material that allows water to pass through while filtering out blocking substances. The porous structure enables stable water flow by controlling the passage of water molecules while blocking larger particles, thus simultaneously achieving blockage prevention and flow stability
Solution Approach 2:
The shielding layer combines the permeability characteristics of cloth material with the protective function of a shielding structure. This composite approach creates a material system that exhibits both filtration capabilities and water permeability, resolving the contradiction between blockage prevention and flow stability
3Reliability
If the shielding layer is completely wrapped around the pipe, then blockage protection is maximized, but manufacturing complexity increases
Solution Approach 1:
The shielding layer is designed as a separable component that can be independently manufactured and then installed on the infiltration pipe. This segmentation allows for simplified manufacturing processes where the shielding layer can be produced separately using standard textile or fabric manufacturing techniques, then easily wrapped and secured around the pipe, reducing overall manufacturing complexity while maintaining complete wrap protection

Function Achieved in This Case
The solution prevents dripper blockages, stabilizes water flow, and improves the uniformity of infiltration, enhancing irrigation efficiency and effectiveness.
Implementation Method 1
the shielding layer is made of a cloth material with a permeable function, and the drip irrigation water flowing out of the dripper seeps out along pores of the cloth material
Implementation Method 2
the shielding layer is made of a cloth material with a permeable function, and the drip irrigation water flowing out of the dripper seeps out along pores of the cloth material
Implementation Method 3
several transverse heat-sealing structures are arranged at interval along the length direction of the drip infiltration pipe strip. The shielding layer and the sewing thread of the shielding layer are heat-sealed to the drip infiltration pipe strip by the transverse heat-sealing structures
