Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating methods for industrial and domestic processes are inefficient, polluting, and lack optimal heat transfer due to the use of external heat sources like free flames and electric resistors, which suffer from energy dispersion and require frequent maintenance, while ferromagnetic induction heating has limitations in thermal conductivity and safety for certain materials.
Innovation Solution
A wireless amagnetic heating module made of an embossed inductive amagnetic alloy with a dielectric surface, allowing for efficient heat transfer and safety by using metals with high thermal conductivity like silver, copper, and aluminum, which can be immersed in fluids or gases to heat them efficiently without direct electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ferromagnetic metals are used for induction heating, then heating efficiency is improved, but thermal conductivity is reduced and safety is compromised
Solution Approach 1:
The patent uses composite materials consisting of amagnetic metal base (aluminum, copper, or silver) combined with ferromagnetic metal particles (iron, nickel, or cobalt) in specific proportions. This composite structure allows the material to exhibit both high thermal conductivity from the amagnetic base and effective magnetic heating properties from the ferromagnetic particles, resolving the contradiction between heating efficiency and thermal conductivity/safety
Solution Approach 2:
The patent changes the magnetic properties parameter by controlling the concentration of ferromagnetic particles (0.1-15% by weight) in the amagnetic metal matrix. By optimizing this parameter, the material achieves sufficient magnetic responsiveness for efficient induction heating while maintaining the high thermal conductivity and safety characteristics of the amagnetic base metal
2Ease of operation
If external heating sources are used, then heating can be applied to materials, but energy dispersion occurs and maintenance requirements increase
Solution Approach 1:
The heating element itself serves as the heat generation source through induction heating, eliminating the need for external heating sources. The amagnetic alloy directly converts electromagnetic energy to thermal energy where needed, reducing energy dispersion and eliminating maintenance of external heating equipment
Solution Approach 2:
The patent replaces traditional mechanical or external thermal heating systems with an electromagnetic induction system. The amagnetic alloy element responds directly to electromagnetic fields, substituting external flame or contact-based heating with a field-based energy transfer method that reduces energy loss and eliminates maintenance of external heating equipment
3Productivity
If contact surface area is increased for heat exchange, then heat transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs curved or spherical surface geometries on the amagnetic alloy heating elements. These curved surfaces naturally increase the contact area with the material being heated compared to flat surfaces, while the simple geometric form avoids adding structural complexity. The convex or spherical shapes facilitate better heat transfer through increased surface contact

AI summary
A non-magnetic wireless heating module is described. The module consists of a, preferably embossed, surface or plane and a dielectric surface or plane. The surface or plane is made of an inductive non-magnetic metal alloy that contains a first amagnetic metal or a first non-magnetic mixture of metals in a percentage between 85% and 99.99% by weight to the total weight and contains a second ferromagnetic or ferrimagnetic metal or a second ferromagnetic or ferrimagnetic mixture of metals in a percentage between 0.01% and 15% by weight to the total weight. The wireless amagnetic heating module is inserted into a chamber (for example a pipe or a portion of a pipe, a cubic container, a cistern . . . ) for the passage or storage of fluids, liquids, gases or solids; when the wireless amagnetic heating module is subjected to a variable electromagnetic field, it heats up, allowing heating, drying, passage of phase, . . . of the material in contact with it and contained in the chamber.
