Innovation Solution
A conducted electrical device with a housing, an ejectable electrode, and a controller that receives audio or video characteristics of the target using sensors, allowing for controlled delivery of an electric current through a system that includes a power supply, sensors, and a communication interface to adjust the power output based on the target's parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high electric current is delivered to the target, then the target is effectively incapacitated, but the risk of causing injury increases
Solution Approach 1:
The patent implements dynamic current adjustment by continuously monitoring target characteristics (weight, height, age, gender, clothing) and modifying the electric current parameters in real-time. The controller dynamically adapts the voltage, current, and pulse duration based on the sensed characteristics, transitioning from static to dynamic operation to optimize incapacitation effectiveness while minimizing injury risk.
Solution Approach 2:
The system changes multiple electrical parameters (voltage, current amplitude, pulse duration, frequency) based on target characteristics. The controller adjusts these parameters according to the sensed data, such as delivering lower current to lighter targets or targets with higher resistance, thereby maintaining effective incapacitation while reducing harmful effects.
2Object-affected harmful factors
If the electric current is reduced to minimize injury, then the target may not be effectively incapacitated
Solution Approach 1:
The patent incorporates feedback mechanisms where sensors continuously monitor target characteristics and the controller adjusts the current delivery based on this feedback. The system senses target properties and uses this information to modulate the electric current in real-time, creating a closed-loop control system that balances incapacitation effectiveness with injury minimization.
Solution Approach 2:
The system performs preliminary sensing and analysis of target characteristics before delivering the electric current. By measuring weight, height, age, and other parameters in advance, the controller pre-calculates the appropriate current parameters, ensuring the delivered current is optimized for effective incapacitation while minimizing injury risk from the outset.
3Object-affected harmful factors
If sensors and control systems are added to adjust current based on target characteristics, then the device can minimize injury, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single controller unit that performs sensing, data processing, parameter calculation, and current delivery control. The controller serves as a multi-functional component that handles various tasks (receiving sensor data, analyzing characteristics, adjusting electrical parameters), thereby reducing the need for separate dedicated components and managing system complexity.
Solution Approach 2:
The system merges the sensing components, processing unit, and control functions into an integrated architecture. The controller combines multiple functions (data reception, analysis, and electrical output control) into a single unified system, reducing the number of separate components and simplifying the overall device structure while maintaining the capability to adjust current based on target characteristics.
