Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intrusive magnetic devices are used to prevent scaling, then magnetic field generation is achieved, but fluid flow is reduced
Solution Approach 1:
The magnetic device is nested within the pipeline structure itself, with the magnetic arrangement positioned between the internal tube (through which fluid flows) and the external tube. This nesting allows the magnetic field generation function to be integrated without protruding into the fluid flow path, thus preventing scaling while maintaining fluid flow productivity.
2Reliability
If magnets are placed around existing piping to generate magnetic field, then magnetic treatment is achieved, but installation complexity and pipe diameter increase
Solution Approach 1:
The magnetic device merges the treatment function with the pipeline structure by using the pipeline walls (internal and external tubes) as the mounting structure for the magnetic arrangement. This combination eliminates the need for separate external mounting structures, simplifying installation and avoiding increases in external pipe diameter.
3Strength
If ferromagnetic materials are used in piping, then structural integrity is maintained, but magnetic field intensity is reduced or eliminated
Solution Approach 1:
The device creates a local non-ferromagnetic zone between the internal and external tubes where the magnetic arrangement is positioned. This local quality change allows the magnetic field to be generated effectively in this specific region without compromising the overall ferromagnetic structure and structural integrity of the piping system.
4Reliability
If magnetic flow density is increased to inhibit scaling, then scaling prevention effectiveness is improved, but device complexity increases
Solution Approach 1:
The device concentrates magnetic flow in the radial dimension (perpendicular to fluid flow) by positioning magnets circumferentially around the internal tube. This dimensional approach allows high magnetic flow density to be achieved at the pipe wall interface without requiring complex axial or longitudinal magnetic structures, thus improving scaling prevention while controlling device complexity.

AI summary
This invention refers to a magnetic anti-scaling device that can be coupled around piping with fluid flow inside it, comprising an external tube; and a plurality of magnetic arrangements, wherein each magnetic arrangement is formed by a cylindric support and a plurality of magnets circumferentially positioned on the cylindric support; where- in the plurality of magnetic arrangements comprises a sequency of magnetic arrangements placed side by side, and likely to be longitudinally coupled around the piping in an axisymmetric arrangement, so as to form, at least, a concentration plan of magnetic field; and wherein a spacer and an absorber are positioned at each end of the axisymmetric arrangement, and the external tube surrounds the axisymmetric arrangement. The application of a high-density magnetic flow orthogonally to the speed of the fluid to be treated inhibits formation of scales at the internal wall of piping, thus reducing scaling at the equipment upstream.
