Solution Overview
Problem
Existing conducted electrical weapons (CEWs) face inefficiencies in delivering stimulus signals to targets, particularly in remote scenarios, leading to inconsistent neuromuscular incapacitation (NMI) and rapid battery depletion due to suboptimal electrode spacing and pulse delivery rates.
Innovation Solution
The CEW incorporates deployment units with electrodes that can be launched remotely, utilizing ionization to establish electrical coupling through air gaps and optimized pulse parameters (e.g., spacing, charge, and rate) to enhance NMI effectiveness while conserving energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If electrodes are deployed remotely with larger air gaps, then the CEW can engage targets at greater distances, but the electrical coupling becomes less reliable and energy consumption increases
Solution Approach 1:
The patent applies parameter changes by optimizing the air gap distance between electrodes and target, and adjusting pulse delivery parameters (voltage, duration, frequency) to achieve reliable electrical coupling at extended ranges. The system modifies these parameters dynamically based on deployment conditions to maintain effective stimulus delivery while managing energy consumption.
2Reliability
If pulse delivery rate is increased to improve NMI effectiveness, then neuromuscular incapacitation is enhanced, but battery depletion occurs more rapidly
Solution Approach 1:
The patent employs periodic action through pulsed electrical stimulus delivery at optimized frequencies and intervals. Rather than continuous high-rate pulsing, the system uses strategically spaced pulses that maintain NMI effectiveness while reducing overall energy consumption. The periodicity is tuned to match physiological responses and achieve cumulative effect with lower total energy input.
Solution Approach 2:
The system dynamically adjusts pulse delivery parameters including voltage magnitude, pulse width, and frequency based on operational requirements and battery status. This parameter optimization allows the CEW to deliver effective NMI stimuli while conserving battery energy, adapting the balance between effectiveness and energy consumption to mission needs.
3Reliability
If electrode spacing is optimized for remote deployment, then NMI effectiveness improves, but the device complexity increases
Solution Approach 1:
The patent segments the electrode assembly into modular components that can be independently configured and deployed. This segmentation allows for optimized electrode spacing and arrangement to maximize NMI effectiveness at remote distances, while the modular design simplifies manufacturing, assembly, and maintenance. The segmented structure enables flexible configuration adapted to different operational scenarios.
