Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional firing pin mechanism is used to initiate percussion initiators, then the initiation function is achieved, but the system complexity increases and manufacturing costs rise
Solution Approach 1:
The patent removes the traditional firing pin mechanism from the system and replaces it with a deformable member that is already present in the ballistic transfer module. This extraction of the separate firing pin component directly reduces system complexity while maintaining the initiation function through the deformation of the existing deformable member under booster pressure.
Solution Approach 2:
The deformable member serves multiple functions: it acts as both a structural component of the ballistic transfer module and as the initiation mechanism for the percussion initiator. This multi-functionality eliminates the need for a separate firing pin, thereby reducing system complexity and manufacturing costs while maintaining reliable initiation.
2Reliability
If a traditional firing pin mechanism is used to initiate percussion initiators, then the initiation function is achieved, but manufacturing and assembly costs increase
Solution Approach 1:
By removing the separate firing pin component, the patent reduces the number of parts that need to be manufactured and assembled. This directly lowers manufacturing and assembly costs while the deformable member's integration into the ballistic transfer module ensures reliable initiation through its deformation under controlled booster pressure.
Solution Approach 2:
The patent combines the initiation function with the existing deformable member of the ballistic transfer module, merging two functions into one component. This consolidation reduces the total number of components, simplifies manufacturing, and lowers assembly costs while maintaining the reliability of percussion initiator initiation.
3Device complexity
If a deformable member is used to initiate percussion initiators, then system complexity is reduced, but the mechanism requires precise deformation control
Solution Approach 1:
The patent utilizes changes in the physical state and properties of the deformable member under controlled pressure from the booster. By designing the deformable member with specific material properties and geometric characteristics, the system achieves reliable initiation through controlled deformation without requiring complex control mechanisms, thus maintaining low system complexity while ensuring precise enough deformation for initiator activation.
4Ease of manufacture
If the deformable member deformation method is used, then manufacturing costs are lowered, but the initiation mechanism requires optimized material properties
Solution Approach 1:
The patent requires the deformable member to have specific material properties that allow controlled deformation under booster pressure to initiate the percussion initiator. By optimizing the material selection and geometric parameters of the deformable member during the design phase, the system achieves cost-effective manufacturing without compromising initiation reliability, as the material properties are tailored to the specific application requirements.
