Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional electronic weapons deliver pulses without monitoring or adjustment, then the device complexity is low, but the uniformity of pulse delivery deteriorates due to manufacturing tolerances and load variations
Solution Approach 1:
The patent implements a feedback mechanism where a detector monitors the actual charge delivered to the load and feeds this information back to a processor. The processor compares the monitored charge with the desired charge and adjusts the capacitance charging goal for subsequent pulses to compensate for deviations, thereby achieving uniform pulse delivery despite manufacturing tolerances and load variations.
Solution Approach 2:
The system performs self-adjustment by automatically modifying its own operating parameters (capacitance charging goal) based on real-time monitoring of pulse delivery. The processor uses the monitored charge information to autonomously recalibrate the charging goal without external intervention, enabling the system to maintain uniformity while adapting to changing conditions.
2Duration of action of moving object
If energy is not conserved through monitoring and adjustment, then the operational duration of the electronic weapon is limited, but implementing monitoring and adjustment increases device complexity
Solution Approach 1:
The system uses feedback to monitor the actual charge delivered and adjust the capacitance charging goal accordingly. This ensures that each pulse delivers the intended amount of charge to the load, preventing energy waste from over-delivery and ensuring consistent effective energy utilization, thereby extending operational duration.
Solution Approach 2:
The processor dynamically changes the operating parameter (capacitance charging goal) based on monitored performance. By adjusting this parameter in response to actual delivery conditions, the system optimizes energy utilization efficiency, ensuring that energy is conserved and operational duration is extended without requiring excessive energy reserves.
3Measurement precision
If the capacitance charging goal is not adjusted based on monitored charge, then the ease of operation is high, but the accuracy of stimulus delivery deteriorates
Solution Approach 1:
The detector monitors the actual charge delivered to the load and provides feedback to the processor. The processor uses this information to automatically adjust the capacitance charging goal for subsequent pulses, ensuring accurate stimulus delivery without requiring manual calibration or complex user intervention, thus maintaining ease of operation while achieving high precision.
Solution Approach 2:
The system performs self-calibration by automatically adjusting its charging goal based on monitored performance. The processor autonomously modifies operating parameters to compensate for deviations, enabling the system to maintain high measurement precision without requiring complex manual control mechanisms or user expertise.

AI summary
An apparatus (100) for interfering with locomotion of a target (1 14) by conducting a current through the target includes according to various aspects of the present invention a transformer, a capacitance, a charge detector (120), and a processor (102). The transformer has a secondary winding that is coupled to the target to provide the current. The capacitance is in series with the secondary winding and is charged to a voltage. The charge detector detects a charge provided through the target by the capacitance and the secondary winding. The processor sets the voltage (e.g., for charging for a next pulse) responsive to the charge detected by the charge detector.
