Innovation Solution
A device using an electromagnetic wave generator to generate electromagnetic waves with resonant frequencies of the target object, transmitted omnidirectionally by an antenna unit, with frequencies between 5 GHz and 10 GHz and intensity below 200 V/m, to inactivate cells, germs, and viruses without damaging human cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal ions are used to inactivate viruses, then inactivation effectiveness is improved, but cost increases and metal ions are easily oxidized
Solution Approach 1:
The patent replaces chemical methods (metal ions) with electromagnetic wave irradiation at resonant frequencies. This substitution eliminates the need for expensive metal ions while maintaining inactivation effectiveness through a different physical mechanism that avoids oxidation issues.
Solution Approach 2:
The patent changes the inactivation mechanism from chemical interaction to resonant frequency electromagnetic wave interaction. By tuning the electromagnetic wave frequency to match the resonant frequency of the virus, the system achieves effective inactivation without the cost and stability problems of metal ion methods.
2Reliability
If ultraviolet irradiation or heating is applied to inactivate microorganisms, then inactivation effectiveness is improved, but human cells are also damaged
Solution Approach 1:
The patent applies electromagnetic waves at specific resonant frequencies that are unique to the target microorganisms. This frequency selectivity ensures that only the intended target absorbs sufficient energy for inactivation, while human cells at different frequencies remain unaffected, achieving localized selective inactivation.
Solution Approach 2:
The patent uses resonant frequency electromagnetic waves to induce violent vibration in the target microorganisms. This resonant vibration causes internal stress and structural damage to the microorganisms, while human cells, having different resonant frequencies, are not subjected to the same damaging effects.
3Reliability
If conventional inactivation devices are used, then inactivation capability is achieved, but selectivity is lost and human cells are affected
Solution Approach 1:
The patent introduces frequency as a critical parameter for selective inactivation. By identifying and applying the resonant frequency of target microorganisms, the system achieves high selectivity. This parameter-based differentiation allows the device to distinguish between target pathogens and human cells, enabling selective inactivation capability.
