Solution Overview
Problem
Existing space hardware protection methods against atmospheric oxidants like atomic oxygen and sulfuric acid are limited to single-material coatings, which do not allow for tailored protection levels and often require additional light reflectors, increasing mass and complexity.
Innovation Solution
A cover comprising multiple layers of different atmospheric oxidant-resistant materials, including glass, silver, and adhesive layers, with integrated optical surface reflectors, allowing for controlled protection and reduced temperature through light reflection, without needing additional reflectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-material coatings are used for protection against atmospheric oxidants, then the protection is uniform and simple to apply, but the protection level cannot be tailored and additional light reflectors are needed increasing mass and complexity
Solution Approach 1:
The cover is segmented into multiple layers (first layer with oxidant-resistant materials, second layer with reflective materials, third layer with conductive materials) rather than using a single uniform coating. This segmentation allows each layer to perform its specific function while collectively providing customizable protection levels against atmospheric oxidants.
Solution Approach 2:
The invention uses composite material structures where different materials are combined in specific layers. The first layer combines oxidant-resistant materials, the second layer combines reflective materials, and the third layer combines conductive materials. This composite approach enables tailored protection while integrating multiple functions into a unified structure.
2Temperature
If additional light reflectors are added for temperature reduction, then the temperature control improves, but the mass and complexity increase
Solution Approach 1:
The reflective function is merged into the second layer of the cover structure itself, rather than being a separate component. The reflective materials in the second layer are integrated with the oxidant-resistant first layer and conductive third layer, creating a multi-functional cover that reduces temperature without requiring additional separate reflectors.
Solution Approach 2:
The cover structure is designed as a universal multi-functional system where the layered structure simultaneously provides oxidant protection, temperature control through light reflection, and electrical conductivity. This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall mass and complexity.
