Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shielding methods for spacecraft are ineffective in preventing penetration of high-energy cosmic rays and solar wind particles, leading to material breakdown and internal radiation damage, with limitations in thermal insulation and reliance on consumable water barriers.
Innovation Solution
An electric charge is placed on the surface of spacecraft using an advanced electric generation system that seizes beta-minus particles and electrons from solar wind, deflecting positively charged particles and generating continuous, sustainable power without fossil or nuclear fuels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multi-layered wrapping materials are used to block particle penetration, then thermal insulation is improved, but protection against high-energy particle impact and penetration is insufficient
Solution Approach 1:
The patent combines multiple materials with different properties into a composite shielding structure. The aluminum exterior housing provides structural integrity and initial particle deflection, while the polyethylene film layer specifically targets neutron radiation through hydrogen content. The beta cloth layer addresses beta particle penetration. This multi-material composite approach resolves the contradiction by providing both thermal insulation and comprehensive radiation protection that single materials cannot achieve alone.
2Object-affected harmful factors
If water is used as a radiation barrier between outer and inner enclosures, then radiation protection is improved, but the barrier effectiveness is reduced as water is consumed
Solution Approach 1:
The patent replaces the consumable water barrier with disposable polyethylene film wrapping that provides equivalent or superior radiation protection without being consumed. The film serves its protective function throughout the mission duration and can be designed as a single-use, non-consumable barrier that maintains effectiveness without degradation from consumption or leakage issues.
3Weight of moving object
If thin aluminum exterior housing is used, then spacecraft weight is reduced, but the housing is easily penetrated by high-velocity particles
Solution Approach 1:
The patent creates a composite shielding system where the thin aluminum housing works in conjunction with specialized radiation-blocking materials. The aluminum provides structural strength and initial particle interaction, while the polyethylene film and beta cloth layers provide specialized protection against different radiation types. This composite approach maintains lightweight construction while achieving comprehensive particle protection that thin aluminum alone cannot provide.

Function Achieved in This Case
The system effectively deflects positively charged particles, reducing internal radiation and providing reliable, efficient, and sustainable power for spacecraft, independent of traditional energy sources, while minimizing material degradation and water consumption.
Implementation Method 1
A process is disclosed by which an electric charge is placed upon the surface, independent segments covering the surface or an extended supplementary surface of the craft sufficient to deflect the positively charged cosmic ray or solar wind particles

AI summary
The present application is the first pragmatic process capable of shielding spacecraft and occupants from destructive impact and penetration of the crafts' exterior walls by positively charged particles of cosmic rays and solar wind. The technology also protects the craft from internal cascading secondary radiation caused by energetic particles that strike the surface and those that penetrate to the interior. Particles posing the highest level of danger to spacecraft are low and high energy protons, positive ions and few-particle nuclei. Accordingly, a reliable, enduring and safe shielding mechanism for spacecraft has not been available until the development of the present application. The shielding is accomplished by conveying a positive electric charge to the atoms and molecules of the exterior surface. Incoming particles are diverted and deflected from the surface by an established electric field derived through an advanced electric system that utilizes electrons emitted by solar wind as electric energy.
