Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective solutions for impact events, such as ballistic objects, are often heavy, bulky, inflexible, and limited to planar surfaces, leading to inefficient energy distribution and reduced effectiveness in absorbing and redirecting forces, which can result in increased injury risk and limited usability in wearable and non-wearable applications.
Innovation Solution
The development of three-dimensional energy distribution structures comprising outer and inner components that absorb and redirect applied forces through a network of interconnected tetrahedral shapes, allowing for a reduced contact surface area and enhanced flexibility to conform to non-planar objects, thereby mitigating the impact energy across a larger area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy and bulky protective layers are used to shield against impact events, then protection effectiveness is improved, but flexibility and ease of movement are reduced
Solution Approach 1:
The protective structure is divided into multiple interconnected tetrahedral units, each capable of independently absorbing and redirecting impact forces. This segmentation allows the overall structure to maintain protection effectiveness while enabling flexibility through the modular arrangement of discrete geometric elements
Solution Approach 2:
The invention transitions from traditional two-dimensional planar protective surfaces to three-dimensional tetrahedral structures. This dimensional change enables the protective layer to conform to complex surfaces and provides inherent flexibility while maintaining impact resistance through the spatial configuration of the tetrahedral geometry
2Stability of the object's composition
If rigid planar surfaces are used for impact distribution, then structural stability is improved, but adaptability to non-planar surfaces is reduced
Solution Approach 1:
The tetrahedral structures are arranged in curved or conforming patterns that adapt to non-planar surfaces. The geometric configuration of interconnected tetrahedra allows the protective layer to follow complex surface geometries while maintaining structural integrity and impact distribution capabilities
Solution Approach 2:
The protective system consists of multiple discrete tetrahedral units that can independently conform to local surface variations. This modular segmentation enables adaptation to non-planar surfaces while the interconnection of units maintains overall structural stability
3Ease of manufacture
If flat surfaces are used for impact absorption, then manufacturing simplicity is improved, but energy distribution effectiveness is reduced
Solution Approach 1:
The invention employs three-dimensional tetrahedral structures instead of two-dimensional flat surfaces. This dimensional transition enables more effective energy distribution through the volumetric configuration of the tetrahedra, which redirect impact forces through multiple geometric paths while remaining manufacturable through modular assembly
4Strength
If solid materials with full volume are used for protection, then strength is improved, but breathability and thermal comfort are reduced
Solution Approach 1:
The tetrahedral protective structures are configured with void spaces between and within the geometric elements, creating a porous or cellular structure. This configuration maintains protective strength through the rigid tetrahedral geometry while allowing airflow and thermal regulation through the interconnected voids, improving breathability and thermal comfort

AI summary
Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.
