Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a scanning electromagnet is used to redirect electron beams, then the beam can be swept across the target to create a curtain or sheet, but the electrical power requirements increase and the system becomes more complex
Solution Approach 1:
The magnetic field system is segmented into two distinct components: a scanning electromagnet for beam sweeping and a permanent magnet array for parallelization. This segmentation allows each component to perform its specific function efficiently, with the permanent magnet array eliminating the need for continuous electrical power to maintain the parallelizing magnetic field.
Solution Approach 2:
The permanent magnet array serves multiple functions: it parallelizes the electron beam trajectory, maintains beam direction stability, and eliminates the need for additional electromagnets that would consume electrical power. This multi-functionality reduces overall system complexity and energy requirements.
2Use of energy by moving object
If permanent magnets are used to parallelize the electron beam, then electrical power requirements are reduced, but the magnetic field strength may degrade over time
Solution Approach 1:
The permanent magnet array is designed with adjustable components that allow the magnetic field strength to be dynamically tuned. This enables compensation for degradation over time and adaptation to different operational requirements, maintaining reliability while using permanent magnets instead of continuously powered electromagnets.
Solution Approach 2:
The system allows for changes in magnetic field parameters (strength and configuration) by adjusting the permanent magnet array. This enables the magnetic field to be optimized for different irradiation needs and compensates for any degradation, ensuring consistent performance without electrical power consumption for field maintenance.
3Device complexity
If the electron beam is kept divergent, then the scanning process is simpler, but the irradiation efficiency decreases
Solution Approach 1:
The magnetic system is divided into two independent functions: scanning (diverging beam control) and parallelization (beam trajectory correction). This segmentation allows the beam to diverge during scanning for simplicity while being parallelized at the target for efficiency, achieving both goals simultaneously through functional separation.
4Ease of operation
If radioisotopes are used as the radiation source, then operational simplicity is improved, but safety concerns and dependence on non-renewable resources increase
Solution Approach 1:
The system replaces the radioactive decay mechanism (nuclear process) with an electron accelerator and magnetic field system (electromagnetic process). This substitution eliminates the safety risks associated with radioisotopes while maintaining the ability to generate ionizing radiation for sterilization and irradiation applications.

Implementation Method 1

Implementation Method 2
This requires a scanning magnet to sweep the electron beam back and forth to create the curtain or sheet to irradiate an item
Implementation Method 3

AI summary
A magnetic apparatus and a method of operating the magnetic apparatus can include a scanning electromagnet that redirects a beam of charged particles, a vacuum chamber that prevents the atmosphere from interfering with the charged particles; and, a parallelizing permanent magnet array for parallelizing the beam of charged particles. The parallelizing permanent magnet array can be located proximate to a target comprising a Bremsstrahlung target or an object that is being irradiated. The magnetic field of the scanning electromagnet can be variable to produce all angles necessary to sweep the beam of charged particles across the target and the parallelizing permanent magnet array can be configured from a magnetic material that does not require an electric current.
