Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arming systems for ordinance, rockets, and missiles are complex and costly due to their reliance on high voltage connectors and wiring, as well as multiple fuzes, which increase size, weight, and cost.
Innovation Solution
The system employs an intermediate voltage generator and detector, using voltages less than 500 volts, and a sequence of events logic to control arm switches, reducing complexity and cost by utilizing low voltage connectors and wiring, and a single arm controller to manage multiple warheads or rockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high voltage connectors and wiring are used in arming systems, then the system can reliably control multiple warheads or rockets, but the system size, weight, and cost increase
Solution Approach 1:
The patent changes the voltage parameter from high voltage (over 500 volts) to low voltage (less than 500 volts) in the arming system. This parameter change allows the system to maintain reliable control of multiple warheads or rockets while reducing the weight, size, and cost associated with high voltage connectors and wiring.
2Reliability
If multiple fuzes are used in arming systems, then the system can safely arm multiple warheads or rockets, but the system complexity and cost increase
Solution Approach 1:
The patent implements a single arm controller that performs the functions previously requiring multiple separate fuzes. This universal controller safely arms multiple warheads or rockets through a single device, reducing system complexity and cost while maintaining the safety and reliability of controlling multiple targets.
3Reliability
If high voltage connectors and wiring are used, then the system can reliably transmit control signals, but the cost and manufacturing complexity increase
Solution Approach 1:
The patent changes the voltage parameter from high voltage to low voltage, which simplifies the manufacturing process by using standard, readily available connectors and wiring. This parameter change maintains reliable signal transmission for controlling multiple warheads or rockets while significantly reducing manufacturing complexity and cost.
