Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the projectile is made lighter to reduce shipping costs and recoil, then velocity and range are improved, but penetration capability and energy transfer to soft tissue deteriorate
Solution Approach 1:
The patent employs composite materials consisting of a polymeric binder matrix filled with metal particles (such as copper, lead, or tungsten). This composite structure allows the projectile to achieve optimal density and penetration capability while maintaining reduced weight compared to conventional solid metal bullets. The metal particles provide mass and penetration force, while the polymeric binder holds them together and allows for frangibility control.
Solution Approach 2:
The patent utilizes parameter changes by controlling the density, size distribution, and composition of metal particles within the polymeric matrix. By adjusting these parameters, the projectile can be optimized for specific performance characteristics including weight, velocity, penetration depth, and frangibility threshold, thereby resolving the contradiction between lightweight design and penetration capability.
2Object-affected harmful factors
If the projectile is designed to be frangible on steel targets for safety, then overpenetration and damage are reduced, but penetration of soft tissue and reliability may deteriorate
Solution Approach 1:
The patent applies local quality by designing the projectile with non-uniform structure where the polymeric binder distribution and metal particle arrangement vary throughout the projectile body. This creates different mechanical properties in different regions, allowing the projectile to maintain structural integrity for reliable soft tissue penetration while having controlled weak points that enable frangibility when impacting hard steel surfaces.
Solution Approach 2:
The projectile's frangibility is made dynamic rather than static. The polymeric binder matrix allows the projectile to maintain strength at operating temperatures and velocities for reliable penetration, while the same polymeric material creates controlled failure points when the projectile impacts steel targets. The dynamic response of the polymeric material to different impact conditions enables both reliable penetration and controlled frangibility.
3Weight of moving object
If the projectile uses polymeric material filled with metal particles to reduce weight, then shipping costs and recoil are reduced, but barrel wear and fouling may increase
Solution Approach 1:
The patent controls barrel fouling by adjusting parameters of the polymeric binder material, including its melting point, viscosity, and thermal stability. By selecting polymeric materials with appropriate thermal properties and by controlling the size and distribution of metal particles, the projectile minimizes residue deposition in the barrel while maintaining the weight reduction benefits of the composite structure.
4Measurement precision
If the projectile geometry is optimized for accuracy and soft tissue disruption, then penetration performance is improved, but feeding reliability into firearms may deteriorate
Solution Approach 1:
The patent employs segmentation by dividing the projectile into distinct geometric zones: a ogive-shaped impact end portion for accuracy and penetration, a cylindrical midsection for balanced aerodynamics, and a base portion with specific dimensions for reliable chamber engagement. This segmented geometry allows each portion to be optimized for its specific function while working together as a unified projectile that maintains both accuracy and feeding reliability.
