Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dummy target active bodies face ignition challenges due to design and geometry, leading to delayed and reduced power development, which affects their effectiveness against threats during the ignition phase, and existing solutions lack a suitable cover set for all-sided ignitability.
Innovation Solution
An active body with multiple pyrotechnic ignition means connected via channels for simultaneous ignition on multiple sides, ensuring rapid and reliable ignition of active substances, including the use of smaller ignition means and inert separation to prevent unwanted ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ignition is performed from one side only, then the structure is simple, but ignition reliability and speed are insufficient
Solution Approach 1:
The active mass is divided into multiple segments with ignition means positioned at different locations (front, rear, and side surfaces). This segmentation allows simultaneous multi-point ignition, improving ignition reliability without requiring a single complex ignition system. Each segment can be ignited independently through its own ignition means, ensuring complete combustion even if one ignition point fails.
Solution Approach 2:
Multiple ignition means are combined to work simultaneously on the same active mass. The patent integrates front ignition means, rear ignition means, and side ignition means that all activate at the same time, creating a merged ignition effect that rapidly ignites the entire active mass from multiple directions, significantly improving ignition reliability.
2Productivity
If fast-burning coating is applied, then all-sided ignition is achieved, but power development is delayed and reduced in initial phase
Solution Approach 1:
Ignition means are pre-positioned at strategic locations on the active mass (front, rear, and side surfaces) before activation. This preliminary arrangement ensures that when ignition is triggered, multiple points ignite simultaneously, creating immediate high-power combustion without the delay associated with coating-based ignition methods that require the coating to burn through first.
3Reliability
If active mass composition or geometry is changed, then ignitability is improved, but adaptability is restricted
Solution Approach 1:
Different regions of the active mass are assigned different ignition characteristics through strategically placed ignition means. The front, rear, and side surfaces each have ignition points optimized for their specific geometric and compositional properties. This local quality approach allows the system to maintain high ignitability across diverse active mass compositions and geometries without requiring a universal design change, thereby preserving adaptability.
