Solution Overview
Problem
Existing ballistic protection systems are limited in their ability to effectively redirect and stop projectiles of varying configurations and velocities, often requiring multiple plates and complex manufacturing processes, which can be costly and uncomfortable to wear.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional flat ballistic plates are used, then the structure is simple and manufacturing is easy, but the ability to redirect and stop projectiles of varying configurations is limited
Solution Approach 1:
The patent applies curvature by forming the ballistic plate with a convex outer surface that is curved rather than flat. This curved geometry causes projectiles to yaw or deflect upon impact, redirecting their trajectory away from the protected area. The curvature is specifically designed to work with projectiles of various configurations and velocities, providing enhanced adaptability without requiring multiple different plate designs.
Solution Approach 2:
The patent changes the geometric parameters of the ballistic plate by incorporating specific curvature radii and surface profiles. The convex surface is defined with particular dimensional parameters that optimize projectile deflection. This parameter modification allows a single plate design to effectively handle varying projectile types and velocities, improving versatility while maintaining manufacturing simplicity.
2Adaptability or versatility
If multiple plates are used to improve protection against various projectiles, then protection effectiveness increases, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent creates a universal ballistic plate design with a convex outer surface that can effectively stop and redirect various types of projectiles including different calibers, configurations, and velocities. This single multi-functional plate replaces the need for multiple specialized plates, reducing assembly complexity while maintaining comprehensive protection effectiveness across different threat scenarios.
Solution Approach 2:
The patent segments the protective function into the geometric configuration of the plate itself, where the convex surface creates multiple deflection zones that handle different projectile types. This functional segmentation within a single unified structure achieves the protection of multiple plates without the complexity of assembling multiple separate components.
3Strength
If heavier materials like steel are used, then stopping power increases, but weight and comfort decrease
Solution Approach 1:
The patent changes the approach from relying solely on material density and weight to achieving stopping power through geometric parameters. The convex surface configuration and curvature radius are optimized to maximize projectile deflection and energy dissipation. This allows the use of lighter materials while maintaining or improving stopping power compared to traditional flat heavy plates, enhancing both protection and wearer comfort.
4Weight of moving object
If ceramic or glass plates are used, then weight is reduced compared to steel, but secondary protection from repeated impacts is compromised
Solution Approach 1:
The convex curved surface design creates a distributed deflection mechanism where each projectile impact engages different portions of the curved geometry. This geometric redundancy provides secondary protection capability, as the curved structure maintains its integrity and redirecting function even after initial impacts, unlike flat ceramic plates that may fracture and lose effectiveness for subsequent threats.
