Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy distribution structures are heavy, bulky, and inflexible, with flat surfaces that maintain or increase the surface area contact during impact events, leading to inefficiencies in wearable applications and limited effectiveness in non-wearable applications due to rigid materials and lack of breathability.
Innovation Solution
The development of three-dimensional, multi-component energy distribution structures that absorb and redirect impact forces through outer and inner components, allowing energy to be dissipated across a reduced surface area, with the ability to conform to non-planar objects and provide flexible protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy and bulky materials are used for impact protection, then protection effectiveness is improved, but flexibility and wearability are worsened
Solution Approach 1:
The protective structure is divided into multiple strata or layers, where each layer can be optimized for specific functions (impact absorption, energy distribution, flexibility). This segmentation allows the system to provide heavy-duty protection where needed while maintaining overall flexibility through the layered architecture.
Solution Approach 2:
The patent employs composite material structures combining different materials with complementary properties - some layers provide heavy-duty impact resistance while other layers provide flexibility and conformability. This composite approach resolves the contradiction by integrating both heavy protection and flexibility into a unified system.
2Ease of manufacture
If flat planar surfaces are used for impact distribution, then manufacturing simplicity is improved, but surface area contact during impact is worsened
Solution Approach 1:
The patent transitions from flat planar surfaces to curved or three-dimensional surfaces for impact distribution. The curved geometry allows impact forces to be distributed across a larger surface area while maintaining manufacturing feasibility through molding or forming processes. This curvature enables better energy dissipation without significantly complicating manufacturing.
3Strength
If solid materials with no voids are used, then structural strength is improved, but breathability and airflow are worsened
Solution Approach 1:
The patent incorporates porous or cellular structures within the protective layers, creating controlled voids that allow airflow and heat dissipation while maintaining structural integrity. These porous materials provide both mechanical strength and breathability, resolving the contradiction between strength and thermal comfort.
Solution Approach 2:
The patent uses nested or hierarchical structures where smaller voids or air channels are embedded within the protective material matrix. This nesting allows breathability and airflow pathways to be integrated within the structural framework without compromising overall strength.
4Strength
If rigid inflexible layers are used, then impact resistance is improved, but ability to conform to surface is worsened
Solution Approach 1:
The patent employs dynamic or semi-rigid materials that can adapt their properties - remaining rigid during impact events for protection while allowing flexibility during normal wear for conformability. This dynamic behavior resolves the contradiction between impact resistance and surface adaptation.
Solution Approach 2:
The patent uses flexible shell structures or thin film layers that can conform to complex surfaces while providing impact protection. These flexible structures maintain足够的 structural integrity for protection while enabling adaptation to irregular geometries.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These structures effectively mitigate impact forces by redirecting energy away from the impact location, reducing damage and enhancing protection while allowing for movement and breathability, providing increased protection against various impact types in both wearable and non-wearable applications.
Implementation Method 1
In response to an impact force, the first structural component can direct a first portion of the impact force away from the second structural component and can pass a second portion of the impact force to the second structural component
Implementation Method 2
The second structural component can direct the second portion away from the region

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.
