Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional lead alloy warheads are used, then manufacturing cost is low and ease of manufacture is high, but environmental harm increases and armor-piercing capability decreases
Solution Approach 1:
The patent changes the material parameter from traditional lead alloy to steel ball, transforming the chemical composition and physical properties of the warhead material to achieve both environmental friendliness and improved penetrating power
Solution Approach 2:
The patent uses a composite structure combining steel ball warhead with specialized bullet support (circular cylindrical support with cardboard support), creating a composite projectile system that optimizes both penetration capability and environmental compatibility
2Manufacturing precision
If spherical warhead with circular cylindrical bullet support is used, then firing precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the bullet into distinct functional segments: spherical warhead, circular cylindrical bullet support, and cardboard bullet support, allowing each component to be optimized independently while maintaining overall precision
Solution Approach 2:
The patent applies different material properties and structural characteristics to different parts of the bullet - the spherical warhead for precision, the circular cylindrical support for stability, and the cardboard support for cost-effectiveness, optimizing each local region for its specific function
3Device complexity
If conventional shotgun bullet design is used, then device complexity is low and manufacturing is simple, but effective shooting distance is limited and power is insufficient
Solution Approach 1:
The patent introduces dynamic stabilization through the circular cylindrical bullet support that allows controlled rotation and movement of the spherical warhead during flight, enhancing stability and extending effective range without significantly increasing complexity
Solution Approach 2:
The patent introduces the circular cylindrical bullet support as an intermediary component between the spherical warhead and the cardboard support, facilitating stable propulsion and controlled flight dynamics that extend shooting distance
