Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical primers are used, then the firearm can be easily discharged, but unauthorized users can access and use the weapon causing accidental shootings and gun violence
Solution Approach 1:
The patent replaces the conventional mechanical primer system with an electronic primer (e-primer) that uses electronic components including a microcontroller, RF receiver, piezoelectric crystal, and switching mechanism. This electronic system requires authorized electronic signals for activation, preventing unauthorized mechanical discharge while maintaining reliable firing when authorized
Solution Approach 2:
The patent introduces an electronic intermediary layer between the mechanical firing pin and the explosive material. The e-primer system acts as a mediator that intercepts the mechanical strike and conditionally activates the firing sequence only when authorized electronic signals are received, thereby controlling accessibility without compromising safety
2Reliability
If electronic primer technology is implemented, then unauthorized discharge is prevented, but the device complexity increases with additional electronic components
Solution Approach 1:
The e-primer system performs multiple functions within a single integrated device: it detects mechanical strikes via piezoelectric crystal, receives and processes electronic authorization signals via RF receiver and microcontroller, controls the firing sequence through electronic switching, and activates the explosive material. This multi-functionality reduces the need for separate safety mechanisms while maintaining security
Solution Approach 2:
The e-primer system is self-activating through energy harvesting from the mechanical strike itself. The piezoelectric crystal converts the kinetic energy of the firing pin strike into electrical energy, which powers the microcontroller and RF receiver, eliminating the need for external batteries or power sources and simplifying the overall system architecture
