Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional coil structure is used to generate a vector potential, then a magnetic field is inevitably produced, but this causes magnetic field leakage that adversely affects other apparatuses
Solution Approach 1:
The coil structure is divided into multiple independent coils (first coil and second coil) with different winding directions. The first coil generates a magnetic field in one direction while the second coil generates a magnetic field in the opposite direction, allowing the harmful magnetic fields to cancel each other out while maintaining vector potential generation
Solution Approach 2:
The patent converts the harmful magnetic field leakage into a beneficial effect by using the magnetic fields from multiple coils to cancel each other out. The magnetic fields that were previously harmful are now used to create a magnetically shielded environment while maintaining vector potential for useful applications
2Ease of operation
If electric manipulation is attempted in a conventional coil structure, then a magnetic field always appears, but this requires strict magnetic shielding in sensitive applications
Solution Approach 1:
The coil system is segmented into multiple coils with opposing winding directions, allowing electric manipulation to be performed while the magnetic fields from different segments cancel each other, eliminating the need for external magnetic shielding
Solution Approach 2:
The patent introduces an intermediary configuration where return current conductors are positioned to create opposing magnetic fields that cancel the primary magnetic fields, serving as a mediator that allows electric manipulation without requiring external magnetic shielding
3Reliability
If a capacitor structure with exposed metal electrodes is used to generate an electric field, then the electrodes are directly exposed to the outside, but this causes corrosion and discharge due to surrounding atmosphere
Solution Approach 1:
The patent introduces a dielectric member as an intermediary between the electrode and the surrounding atmosphere. This dielectric layer protects the electrode from direct contact with corrosive atmospheric elements while still allowing the electric field to be generated and function properly
Solution Approach 2:
A thin dielectric film or coating is applied to the electrode surface, creating a protective barrier that prevents corrosion and discharge while maintaining the electrode's electrical functionality for electric field generation
4Reliability
If a capacitor structure is used, then the load impedance becomes capacitive and the impedance increases, but this makes impedance matching difficult
Solution Approach 1:
The patent changes the electrical parameters of the system by introducing inductive elements (coils) that can compensate for the capacitive nature of the capacitor structure. By adjusting the inductance and capacitance values, the overall impedance can be optimized for better impedance matching with connected devices
5Reliability
If a conductive medium is placed inside an electric field when time varying magnetic field is applied, then eddy current is generated in a circle, but this makes it difficult to apply electric current linearly in the specific point
Solution Approach 1:
The patent divides the current path into multiple segments using a multi-turn coil structure, where each turn contributes to the overall magnetic field while the return current path is designed to minimize eddy current effects. This segmentation allows linear current application at specific points while maintaining reliable magnetic field generation
