Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If alternating magnetic fields are used to set nanoparticles into vibration for cell destruction, then cell destruction is achieved, but treatment time becomes excessively long
Solution Approach 1:
The patent applies mechanical vibration through Alfvén waves generated by two coils to set nanoparticles into intense vibration, causing cell membrane rupture. This mechanical vibration approach achieves cell destruction much faster than conventional alternating magnetic fields, directly resolving the contradiction between destruction efficiency and treatment time.
Solution Approach 2:
The patent changes the physical parameters of the magnetic field by using two coils to generate Alfvén waves instead of simple alternating magnetic fields. This parameter change enables much faster nanoparticle deflection and cell destruction, reducing treatment time while maintaining effectiveness.
2Productivity
If simple alternating magnetic fields are used to deflect nanoparticles, then cell destruction is achieved, but destruction efficiency is too low
Solution Approach 1:
The patent uses Alfvén waves to induce intense mechanical vibration in nanoparticles, achieving much higher deflection amplitudes compared to simple alternating magnetic fields. This results in reliable and efficient cell membrane rupture, simultaneously improving both destruction efficiency and effectiveness.
Solution Approach 2:
The patent employs periodic action through Alfvén waves that oscillate at specific frequencies to maximize nanoparticle deflection. This periodic magnetic field action enhances the mechanical stress on cell membranes, improving destruction reliability while maintaining high efficiency.
3Productivity
If heat input is used to destroy tumour cells, then cell destruction is achieved, but surrounding healthy tissue is damaged
Solution Approach 1:
The patent replaces the thermal mechanism (heat input) with a mechanical mechanism (Alfvén wave-induced nanoparticle vibration). This substitution destroys tumour cells through mechanical stress on cell membranes rather than thermal damage, eliminating the harmful effect on surrounding healthy tissue while maintaining effective tumour cell destruction.
Solution Approach 2:
The patent uses nanoparticles as intermediaries that are selectively attached to tumour cells. These nanoparticles serve as mediators that convert magnetic field energy into mechanical vibration specifically at the tumour cell location, enabling precise destruction without affecting healthy surrounding tissue.
4Productivity
If heat dissipation is used for tumour cell destruction, then cell destruction is achieved, but control precision is reduced
Solution Approach 1:
The patent replaces thermal control (heat dissipation) with mechanical control (Alfvén wave frequency and amplitude). The mechanical approach allows precise control of nanoparticle vibration through electromagnetic field parameters, significantly improving control precision while maintaining effective tumour cell destruction.

AI summary
A device for environmentally friendly destruction of health-relevant and cosmetically/aesthetically relevant cell structures, in particular tumour cells, which have at least one metallic nanoparticle on their cell membrane, is disclosed. The device includes a primary coil for generating an inhomogeneous primary magnetic field, a secondary coil for generating an inhomogeneous secondary magnetic field and a control device which is designed for actuating the primary coil in such a way that the nanoparticle is deflected by the primary magnetic field and for actuating the secondary coil in such a way that the secondary magnetic field oscillates in relation to the primary magnetic field and deforms it periodically in order to generate Alfvén waves which deflect the nanoparticle, whereby the cell membrane of the cell structure is torn up by the nanoparticle and the cell structure is consequently destroyed.
