Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional paintballs are used, then high kinetic energy is achieved for effective target penetration, but significant pain and damage occur at close ranges
Solution Approach 1:
The projectile is divided into multiple hollow hemispherical segments that can separate upon impact. This segmentation reduces the mass of the projectile while maintaining structural integrity during flight, thereby reducing kinetic energy and impact damage while preserving ballistic accuracy
Solution Approach 2:
The projectile uses flexible thermoplastic elastomer or thermoplastic rubber material for the hollow segments. This flexible material allows the projectile to deform during impact, absorbing energy and reducing the force transmitted to the target, thus reducing pain and damage while maintaining reusability
2Duration of action of stationary object
If reusable projectiles with mass similar to conventional paintballs are used, then economy and reusability are achieved, but the same damaging impact energy is transmitted
Solution Approach 1:
The hollow segmented structure reduces the overall mass of the reusable projectile compared to solid reusable projectiles. This mass reduction directly decreases kinetic energy and impact damage while the durable thermoplastic material ensures the projectile remains reusable
Solution Approach 2:
The projectile parameters (mass, volume, structure) are changed by using a hollow segmented design rather than a solid structure. This parameter change reduces kinetic energy and impact energy while maintaining reusability through the durable material construction
3Object-affected harmful factors
If foam darts with low impact energy are used, then safety for indoor use is achieved, but quality and features are inferior to paintball markers
Solution Approach 1:
The projectile parameters are optimized to achieve low impact energy through reduced mass and hollow segmented structure, while maintaining compatibility with paintball marker systems. This allows the projectile to work with high-quality paintball markers while being safe for indoor use
Solution Approach 2:
The projectile uses composite construction with thermoplastic elastomer or thermoplastic rubber materials that provide both the flexibility needed for low impact energy and the durability required for quality and reliability comparable to paintball markers

AI summary
A hollow spherical projectile is constructed from a plurality of curved structural segments and has a plurality of openings. The projectile can be fired by a conventional paintball marker with a high degree of ballistic accuracy. The projectile is reusable and is fabricated from a flexible and resilient material. The outer surface of the projectile exhibits low friction, achieved by the material itself or by having a low friction coating applied. The projectile possess and transmits less kinetic energy than a conventional paintball and therefore inflicts less pain and damage upon impact. Fabrication can be accomplished by 3D printing, or molding as a single seamless piece, or as a plurality of pieces which are then assembled.
