Debris Capture Pouch with Aerogel Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing space shielding solutions are ineffective in capturing larger debris particles that can cause significant damage to spacecraft, as they often expel smaller debris back into the space environment, increasing collision risks.
Innovation Solution
A debris particle capture system comprising a particle-absorbing core with an impact surface, an exit surface, and an absorptive media, enveloped by a semi-penetrable pouch with impact and capture membranes, designed to capture and dissipate debris particles by fracturing them and trapping the fragments within the absorptive media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing space shielding solutions are used to protect spacecraft from debris, then protection is provided, but more debris particles are expelled back into space environment, increasing collision risk
Solution Approach 1:
The patent converts the harmful impact of debris particles into a beneficial capture mechanism. The aerogel material, which would normally be damaged by hypervelocity impacts, is instead designed to capture and retain debris particles through adhesion and mechanical interlocking, transforming the harmful impact event into a useful debris removal function.
Solution Approach 2:
The patent employs aerogel, a highly porous material with extremely low density and high surface area. The porous structure allows debris particles to penetrate and become trapped within the three-dimensional network, providing effective capture while minimizing the generation of secondary debris compared to solid shielding materials.
2Reliability
If aerogel is used to capture hypervelocity particles, then capture capability is achieved, but only for particles orders of magnitude smaller than damaging sizes
Solution Approach 1:
The patent modifies key parameters of the aerogel material including density, pore size distribution, and mechanical strength to extend the effective capture range from sub-millimeter particles to centimeter-scale debris. These parameter adjustments allow the aerogel to maintain capture effectiveness across a broader spectrum of particle sizes while retaining the low debris generation advantage.
Solution Approach 2:
The patent utilizes composite aerogel structures combining different materials (such as silica, polymer, or metal oxides) to enhance both the capture capability and the size range of可有效捕获的debris particles. The composite structure provides improved mechanical properties and adhesion characteristics necessary for capturing larger, more damaging debris while maintaining the lightweight advantage.
3Object-affected harmful factors
If a particle-absorbing core with absorptive media is used, then debris capture and dissipation is improved, but device complexity increases
Solution Approach 1:
The patent divides the debris protection function into distinct segments: an impact surface for initial particle engagement, an absorptive media core for capture and energy dissipation, and an exit surface for debris containment. This segmentation allows each component to be optimized independently while working together to provide comprehensive debris capture with controlled complexity.
