Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buried drainage systems fail to effectively separate and recycle magnetic substances, leading to contamination and inefficient treatment of ferromagnetic substances in sewage.
Innovation Solution
An intelligent and durable buried drainage pipe with a non-magnetic, aging-resistant design featuring a two-layer structure, where a permanent magnet and electromagnets are used to attract and transfer magnetic substances from the outer pipe to a collecting area, preventing them from entering the inner pipe and enabling centralized treatment and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If magnetic substances are not separated in the drainage pipe, then the drainage system is simpler, but magnetic substances contaminate the magnetic field and require centralized treatment which is inefficient
Solution Approach 1:
The patent extracts magnetic substances from the drainage flow using magnetic separation devices (permanent magnets and electromagnets) installed within the drainage pipe. The magnetic substances are pulled out of the water flow and collected in a separate collecting area, preventing them from contaminating the magnetic field downstream while avoiding the need for centralized treatment facilities.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary mechanism between the flowing water and the magnetic substances. The permanent magnets and electromagnets create magnetic fields that interact with ferromagnetic particles in the water, enabling separation without direct mechanical contact. This intermediary approach allows efficient separation while maintaining a relatively simple pipe structure.
2Productivity
If magnetic substances are collected centrally, then recycling is possible, but the treatment process becomes more complex and less efficient
Solution Approach 1:
The patent performs magnetic separation at the source (within the drainage pipe itself) rather than collecting all magnetic substances for centralized treatment later. The permanent magnets and electromagnets continuously separate magnetic substances as water flows through the pipe, preventing accumulation and enabling immediate recycling or disposal without complex centralized processing facilities.
Solution Approach 2:
The drainage pipe system performs its own magnetic separation function through integrated permanent magnets and electromagnets, eliminating the need for separate centralized treatment facilities. The system serves itself by incorporating the separation capability directly into the drainage infrastructure, improving productivity while reducing overall system complexity.
3Reliability
If a two-layer pipe structure with magnets is used, then magnetic substances are separated effectively, but the pipe structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into a single integrated structure: the outer pipe serves as both the structural conduit and the housing for magnetic separation devices. The permanent magnets and electromagnets are mounted directly on the outer pipe wall, and the collecting area is formed within the annular space between the inner and outer pipes. This merging approach achieves effective separation while minimizing structural complexity compared to separate systems.
Solution Approach 2:
The patent employs a nested structure where the inner pipe is positioned within the outer pipe, creating an annular collecting area between them. The permanent magnets and electromagnets are nested on the outer surface of the outer pipe, and the magnetic substances are collected in the nested annular space. This nested arrangement achieves effective separation with compact geometry, balancing reliability and structural simplicity.
Applied Scientific Principles

Function Achieved in This Case
The system automatically treats and separates magnetic substances, preventing contamination and facilitating their recycling by using a permanent magnet and electromagnets to cyclically transfer and collect magnetic substances, ensuring efficient separation and treatment without entering the inner pipe.
