An intelligent module spiral pipeline system with arch-shaped units, reinforced rib structures, and integrated leakage detection, featuring a winding machine that spirally arranges modules with a staggered pattern and includes sponge holes for rainwater absorption, allowing for increased ring-stiffness, reduced costs, and automated assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If extrusion moulding is used for large aperture pipelines, then production efficiency is improved, but ring-stiffness cannot be increased and transportation becomes troublesome
Solution Approach 1:
The pipeline is divided into modular units that can be separately manufactured with optimal ring-stiffness characteristics and then assembled together. Each module maintains structural integrity while enabling flexible transportation and installation.
Solution Approach 2:
The patent employs composite material structures within the modular units to achieve high ring-stiffness while maintaining manufacturability through extrusion moulding. The composite design allows optimization of mechanical properties without sacrificing production efficiency.
2Ease of manufacture
If modularized pipes are assembled on site, then transportation is simplified, but secondary processes and frame winding increase cost
Solution Approach 1:
The patent integrates the fixing devices and locking mechanisms directly into the modular units themselves, eliminating the need for separate frames and secondary assembly processes. The modules are designed to interlock and fix each other through built-in features, simplifying the overall assembly process.
Solution Approach 2:
The modular units are equipped with self-fixing and self-locking capabilities through integrated devices that automatically engage during assembly. This self-service mechanism eliminates the need for additional fixing operations or external frame structures.
3Ease of operation
If traditional pipelines are buried underground, then installation is completed, but leakage detection becomes impossible
Solution Approach 1:
The patent incorporates leakage detection systems that provide real-time feedback on pipeline integrity. Sensors embedded in or attached to the modular units monitor for leaks and transmit information to a central system, enabling continuous monitoring even when buried underground.
Solution Approach 2:
The patent replaces traditional mechanical leakage detection methods with electronic or optical sensing systems that can function effectively underground. These substitution systems use electrical or electromagnetic signals to detect and report leakage conditions.
