Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed electrodes are used in particle beam systems, then the system structure is simple, but the capability to control particle flow and produce defined beam shapes is limited
Solution Approach 1:
The patent applies the dynamics principle by making electrodes movable relative to each other transverse to the particle beam direction. This allows the electrode configuration to be dynamically adjusted to produce different beam shapes (circular, rectangular, triangular, etc.) and control particle flow, transforming a static system into a versatile dynamic system without requiring complete redesign for each application.
Solution Approach 2:
The patent divides the electrode system into multiple separable electrodes that can be independently positioned. This segmentation allows each electrode to be moved to specific locations to create different field configurations, enabling flexible beam shaping while maintaining a modular structure that doesn't require complete system redesign for different applications.
2Adaptability or versatility
If traditional electrostatic lenses are used, then the system is simple, but the ability to produce circularly polarized beams and adjustable optical axes is limited
Solution Approach 1:
The patent uses movable electrodes that can be positioned to generate rotating electric and/or magnetic fields. By dynamically adjusting the position and configuration of the electrodes, the system can produce circularly polarized beams and adjust the optical axis direction, providing polarization control capability that transforms a simple static lens system into a versatile dynamic field generation system.
3Manufacturing precision
If movable electrodes are introduced for beam control, then beam shaping capability is improved, but the risk of electrical discharge and damage to components increases
Solution Approach 1:
The patent applies flexible thin films as protective insulating coatings on the movable electrodes. These thin film layers provide electrical insulation to prevent discharge between electrodes and between electrodes and the particle guiding tube, while being thin enough to not significantly interfere with the electric field generation and beam focusing functionality, thus protecting components without compromising beam control precision.
Solution Approach 2:
The patent introduces insulating layers as intermediary protective barriers between the movable electrodes and the particle guiding tube. These intermediary layers prevent direct electrical contact that could cause discharge, acting as a mediator that protects the tube from damage while allowing the electrodes to maintain their positioning and field generation functions for precise beam focusing.
4Reliability
If protective films are applied to all surfaces, then component protection is improved, but the system complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies protective insulating films selectively only on the surfaces of movable electrodes that are at risk of electrical discharge (such as surfaces facing other electrodes or the particle guiding tube), rather than coating all surfaces uniformly. This local quality approach provides necessary protection against discharge while minimizing the amount of coating material and simplifying the manufacturing process by focusing protection only where it is critically needed.
