Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing FIR-emitting composites achieve emissivity of only up to 0.95, failing to reach the theoretical limit of 1.0, and lack a method to effectively simulate a fever-like condition for therapeutic benefits without raising the body's overall temperature.
Innovation Solution
A ceramic module composed of hosting, FIR-base, and cation-doping oxides, sintered at controlled temperatures to create an inhomogeneous crystal structure, enabling both blackbody-like thermal radiation and stimulated FIR-photon radiation, achieving emissivity greater than 1.0 and simulating a 1-3°C temperature increase in localized body regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional FIR-emitting composites are used with standard sintering processes, then the manufacturing process is simple, but the emissivity only reaches 0.90-0.95 and cannot exceed the theoretical limit of 1.0
Solution Approach 1:
The patent applies parameter changes by modifying the sintering temperature to exceed the melting point of specific constituent oxides (such as zinc oxide at 1975°C or bismuth oxide at 825°C). This extreme parameter change enables the formation of a unique glassy phase with emissivity greater than 1.0, resolving the contradiction between manufacturing simplicity and emissivity precision.
Solution Approach 2:
The patent uses composite materials by combining multiple metal oxides (e.g., zinc oxide, bismuth oxide, aluminum oxide, silicon oxide) in specific ratios. The interaction between these oxides during ultra-high temperature sintering creates a composite structure with enhanced emissivity properties that individual materials cannot achieve alone.
2Temperature
If the ceramic module emits only blackbody thermal radiation, then the radiation follows physical laws, but the effective temperature cannot exceed the actual temperature of the module
Solution Approach 1:
The patent creates a 'virtual fever' condition by copying the thermal radiation characteristics of a hotter blackbody without actually heating the ceramic module to that temperature. The unique emissivity material properties enable the module to emit radiation equivalent to a higher temperature source, achieving the desired therapeutic effect without the energy input required for actual heating.
Solution Approach 2:
The patent changes the emissivity parameter of the ceramic material to greater than 1.0 through ultra-high temperature sintering. This parameter change allows the module to emit enhanced thermal radiation that appears as if from a higher temperature source, enabling temperature simulation without actual thermal heating.
3Productivity
If transition metal oxides are used to tune band gap and lattice constant, then FIR radiation efficiency is improved, but the sintering temperature must exceed oxide melting points
Solution Approach 1:
The patent exploits phase transitions by heating the oxide mixture beyond the melting points of constituent oxides, creating a liquid phase during sintering. This phase transition enables complete mixing and formation of a homogeneous glassy phase upon cooling, which achieves the desired high emissivity and FIR radiation efficiency.
Solution Approach 2:
The patent dramatically changes the sintering temperature parameter to exceed the melting points of transition metal oxides (e.g., zinc oxide at 1975°C, bismuth oxide at 825°C). This extreme temperature parameter enables the formation of a unique emissivity-enhancing phase that cannot be created at conventional sintering temperatures.

AI summary
This invention relates to a ceramic module for assembly into a therapeutic device for treating a human or animal body with irradiation of far infrared. More specifically, said ceramic module can simultaneously emit blackbody-like thermal radiation and stimulated FIR-photons radiation in 3-16 μm wavelength spectrum, while the overall radiation in 8-14 μm wavelength range is measured to be an approximated blackbody radiation at a temperature that is at least 1° K (or 1° C.) higher than the actual body temperature of said ceramic module, signifying an effective emissivity greater than 1.0. Said ceramic module may be used alone or serve as components of a therapeutic device for increasing physiologic performance, immune competence, health, and mean lifespan of human or animal.
