Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional RF devices are used for charged particle transportation, then particle transport is achieved, but positively and negatively charged particles cannot be combined into a single packet for synchronized analysis
Solution Approach 1:
The patent applies a dynamic, time-varying electric field with moving pseudopotential extrema that can adapt its configuration to transport both positively and negatively charged particles simultaneously. The extrema move along the channel to guide particles of opposite charges in a synchronized manner, enabling combined packet formation for improved analysis efficiency.
2Volume of moving object
If spatial compression of charged particles is performed to reduce emittance, then packet size is reduced, but particles of different masses and kinetic energies become difficult to separate and transport synchronously
Solution Approach 1:
The patent creates localized regions with different pseudopotential extrema along the transport channel, where each region can be optimized for specific particle properties. This allows differential control of particles with different masses and kinetic energies within the compressed packet, maintaining separation precision while achieving spatial compression.
Solution Approach 2:
The moving pseudopotential extrema dynamically adjust the local field configuration during transport, enabling continuous adaptation to the varying positions and energies of compressed particles. This dynamic adjustment maintains synchronous transport of particles with different masses even under spatial compression.
3Adaptability or versatility
If a non-uniform electric field with moving pseudopotential extrema is created, then both positive and negative charged particles can be transported synchronously, but device complexity increases
Solution Approach 1:
The patent employs periodic modulation of the electric field through time-varying voltages applied to the electrodes, creating the moving pseudopotential extrema. This periodic action generates the complex field pattern needed for synchronized particle transport without requiring permanently complex electrode structures, as the complexity is achieved through temporal modulation rather than static configuration.

AI summary
The present invention is concerned with a device for charged particle transportation and manipulation. Embodiments provide a capability of combining positively and negatively charged particles in a single transported packet.
