Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pyrotechnic devices are used with direct handling of pyrotechnic material for sequencing, then assembly can be performed, but safety risks increase and handling becomes delicate
Solution Approach 1:
The patent introduces transmission tips as intermediary components that connect the ignition tip to multiple pyrotechnic products through a fuse system. This intermediary structure eliminates the need for direct handling of pyrotechnic material during assembly, as workers can safely attach products to transmission tips without exposing themselves to live pyrotechnic compositions. The fuse acts as a safe mediator that transfers ignition energy without requiring manual manipulation of sensitive pyrotechnic materials.
2Reliability
If traditional pyrotechnic devices require delicate handling and intervention on pyrotechnic material, then sequencing can be achieved, but production speed decreases
Solution Approach 1:
The transmission tips are pre-configured with fuse connections during manufacturing, establishing the ignition sequencing pathway before the pyrotechnic products are assembled. This preliminary preparation of the ignition system allows workers to simply attach products to pre-prepared transmission tips without performing delicate operations on pyrotechnic material during assembly, thereby maintaining sequencing accuracy while dramatically increasing production speed.
3Productivity
If multiple transmission tips are connected at different distances along the fuse, then sequential ignition is achieved, but device complexity increases
Solution Approach 1:
The ignition system is segmented into modular transmission tips that can be independently positioned at different distances along the fuse. Each transmission tip is a discrete component that connects to the fuse at a specific location, creating distinct ignition zones for different pyrotechnic products. This segmentation allows for flexible configuration of sequencing patterns while maintaining manageable device complexity through standardized modular components.
