Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If spark gap technology is used for HPEM effector systems, then high power radiation (up to several 100 MW or GW) can be achieved, but high temporal jitter occurs leading to poor synchronization accuracy
Solution Approach 1:
The patent replaces spark gap technology with semiconductor-based HPEM sources that use electronic switching mechanisms instead of mechanical/electrical discharge processes. This substitution eliminates the temporal jitter inherent in spark gap systems while maintaining high power radiation capability through controlled semiconductor switching and pulse generation circuits.
Solution Approach 2:
The patent changes the operating parameters of the HPEM sources by using semiconductor devices with controllable switching times and pulse widths. This allows precise control of the temporal characteristics of the radiated pulses, enabling accurate synchronization across multiple sources while maintaining high power output levels.
2Length of stationary object
If multiple HPEM sources are synchronized to increase range, then the field amplitude in the far field increases, but synchronization becomes difficult due to temporal jitter
Solution Approach 1:
The patent replaces the problematic synchronization mechanism of spark gap systems with semiconductor-based timing control. The semiconductor sources can be precisely synchronized using electronic timing circuits and control logic, enabling multiple sources to operate in unison for enhanced far-field amplitude while maintaining accurate temporal coordination.
Solution Approach 2:
The patent implements feedback mechanisms in the semiconductor-based HPEM system to monitor and adjust the timing of each source. This allows real-time synchronization adjustment to compensate for any temporal variations, ensuring precise coordination of multiple sources for maximum range and amplitude enhancement.
3Measurement precision
If semiconductor-based HPEM systems are used, then synchronization accuracy improves, but the radiated power and application range against diverse targets are limited
Solution Approach 1:
The patent merges multiple semiconductor-based HPEM sources into a coordinated array system. By combining the output of multiple synchronized semiconductor sources, the system achieves high total radiated power while maintaining the synchronization accuracy inherent in semiconductor technology. The merged output can be directed toward diverse targets through beam steering capabilities.
Solution Approach 2:
The patent designs the semiconductor-based HPEM system with multi-functionality to address diverse target types. The system can adjust pulse parameters such as width, amplitude, and frequency to effectively combat different target classes (UAS, IED, C4I) while maintaining precise synchronization across all sources.
4Reliability
If a fixed HPEM system configuration is used for a specific target class, then the system is optimized for that target, but adaptability to other target classes is limited
Solution Approach 1:
The patent implements dynamic reconfiguration capabilities in the HPEM system, allowing the pulse parameters (width, amplitude, frequency) and source activation patterns to be adjusted in real-time based on the detected target type. This dynamic adaptability enables the same hardware system to effectively counter diverse target classes including UAS, IED, and C4I devices.
Solution Approach 2:
The patent designs the HPEM system with universal capabilities to address multiple target classes through a single platform. The system incorporates programmable control logic and adjustable pulse generation parameters that can be reconfigured to match the sensitivity spectrum and operational characteristics of different target types, eliminating the need for separate dedicated systems.

AI summary
An effector arrangement for combatting a threat which includes targets, contains HPEM sources, an input and/or a memory for a mission specification (76) and/or a prioritization for combatting a threat and a control device, which assigns the threat scenarios and target classes and, depending thereon, HPEM characteristics and, depending thereon, HPEM sources, and which activates the assigned HPEM sources depending on the threat scenarios, target classes, HPEM characteristics, mission specifications and/or prioritizations to combat the threat. A method for combatting the threat includes providing the mission specification and/or the prioritization. The control device assigns the threat scenarios and target classes to the threat and, depending thereon, the HPEM characteristics and, depending thereon, the HPEM sources, and activates the assigned HPEM sources depending on the threat scenarios, target classes, HPEM characteristics, mission specifications and/or prioritizations to combat the threat.
