Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visible or infrared light is used for active imaging, then the system can operate in conventional spectrum, but the resolution is limited due to wavelength constraints
Solution Approach 1:
The patent changes the fundamental parameter of the illuminating beam from optical photons to charged particles (electrons or ions). This parameter change enables extended range imaging beyond the limitations of visible and infrared wavelengths while maintaining the ability to detect returned signals for high-resolution imaging.
2Reliability
If surface reflectance is used for signal detection, then the system can detect returned light, but the effectiveness is limited at extended ranges
Solution Approach 1:
The patent replaces the optical detection mechanism (detecting reflected light) with a charged particle detection mechanism. By using a charged particle beam that can be detected when it returns or interacts with the target, the system achieves reliable detection at extended ranges where optical reflectance methods fail.
3Measurement precision
If a particle beam is scanned over extended distances, then high-resolution imaging at extended range is achieved, but beam charge control becomes necessary to maintain beam quality
Solution Approach 1:
The patent introduces a beam charge control subsystem as an intermediary component between the particle source and the target. This subsystem actively manages the charge state of the particle beam during flight, neutralizing or adjusting charge to prevent beam dispersion and maintain imaging resolution over extended distances.
