Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional solid bullet designs are used, then stability and rotational balance are improved, but aerodynamic drag increases and range decreases
Solution Approach 1:
The patent applies a hollow interior structure within the bullet body that allows air to pass through during flight. This porous configuration reduces aerodynamic drag by enabling airflow through the projectile rather than forcing all air to flow around it, directly addressing the drag problem while maintaining external stability features
Solution Approach 2:
The bullet is divided into distinct segments: a solid exterior shell providing stability and a hollow interior providing aerodynamic benefits. This segmentation allows the bullet to simultaneously achieve rotational stability through its external form while reducing drag through its internal structure
2Ease of manufacture
If traditional bullet shapes are used, then manufacturing simplicity is maintained, but aerodynamic efficiency and range are reduced
Solution Approach 1:
The manufacturing process is segmented into creating the hollow interior and forming the exterior shell separately or simultaneously. This allows traditional manufacturing methods to be used for the external shape while incorporating the drag-reducing hollow structure, achieving both manufacturing simplicity and improved range
Solution Approach 2:
The hollow interior structure is integrated into the manufacturing process using techniques such as mandrel removal or dual-wall forming, allowing the bullet to be produced with reduced drag characteristics while maintaining compatibility with existing manufacturing capabilities

AI summary
A firearm projectile device is provided. The device is comprised of a projectile body with a partially hollow area that allows air to travel through the projectile and reduces the projectile's coefficient of drag. Both ends of the device are preferably pointed to further reduce the coefficient of drag of the device. In addition, the second end attaches to a fitted gas block that seals the projectile from a propellant within the casing of the device.
