Solution Overview
Problem
Current materials are inadequate for effectively storing, dissipating, and releasing high-frequency, high-magnitude energy from collisions and shock waves, often resulting in extensive damage and injury due to inefficient energy absorption and transmission.
Innovation Solution
A system comprising porous particles with lyophilic exteriors and lyophobic interiors, combined with a carrier fluid, that accumulates energy by allowing the fluid to penetrate the pores under pressure, reducing energy transmission to protected objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional protective materials (foam, gels, rubber) are used to absorb impact energy, then some energy dissipation is achieved, but most energy is reflected back or transmitted through, causing damage and injury
Solution Approach 1:
The invention uses particles with porous structures that allow carrier fluid to penetrate into the pores under impact pressure. The porous structure provides large surface area for fluid-particle interaction, enabling efficient energy accumulation through fluid displacement and pressure buildup within the pores, while minimizing energy reflection and transmission.
Solution Approach 2:
The invention creates a composite system combining particles (with specific porous structure and surface properties) and carrier fluid. The particles have lyophobic interior surfaces that repel the carrier fluid at rest, but under high pressure the fluid is forced into the pores. This composite particle-fluid system provides superior energy accumulation and dissipation compared to single materials.
2Object-affected harmful factors
If high-density protective materials are used to block energy transmission, then energy transmission is reduced, but the materials cannot effectively store and release energy in a controlled manner
Solution Approach 1:
The system transitions from a static protective material to a dynamic system where the carrier fluid moves in and out of the particle pores in response to applied pressure. During impact, fluid is forced into pores accumulating energy; during release, fluid exits the pores. This dynamic fluid displacement provides controlled energy storage and release, unlike static high-density materials.
Solution Approach 2:
The invention changes the physical state and distribution of the carrier fluid under different pressure conditions. At rest, fluid is excluded from pores due to lyophobic surfaces. Under impact pressure, fluid penetrates into pores. This parameter change (fluid position and pressure state) enables the system to adapt its energy absorption and release characteristics dynamically.
