Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Atmospheric suits, particularly in deep space environments, lack effective monitoring systems to detect immediate threats such as micrometeoroid impacts or pressure and temperature changes that can compromise the integrity and safety of the wearer.
Innovation Solution
Integration of a fiber optic sensing network within the suit's layers, using optical fibers offset at specific angles with structural fibers, along with a light source, photodetector, and processing circuitry to identify anomalies like fiber breakage, strain, or temperature changes, and generate alerts for the wearer or external systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fiber optic sensing network is integrated into the atmospheric suit layers, then monitoring capability for threats like micrometeoroid impacts and environmental changes is improved, but device complexity increases
Solution Approach 1:
The patent combines structural reinforcement fibers with sensing optical fibers into a single integrated layer structure. The optical fibers are embedded within the same layers that provide mechanical strength and environmental protection, eliminating the need for separate sensing layers and reducing overall system complexity despite adding monitoring functionality.
Solution Approach 2:
The patent creates multi-functional fiber layers that simultaneously provide structural support and sensing capabilities. The same layers that protect against micrometeoroid impacts and maintain suit integrity also detect threats through integrated optical fibers, allowing single components to serve multiple functions.
2Measurement precision
If optical fibers are interspersed with structural fibers in the suit layers, then detection precision for anomalies like fiber breakage and strain is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the suit construction into distinct layers, with optical fibers embedded within specific structural layers rather than mixed throughout the entire suit. This segmentation allows manufacturing processes to focus on integrating sensing fibers into predetermined locations within layers, simplifying the overall manufacturing approach while maintaining detection precision.
Solution Approach 2:
The patent uses the structural fiber layers themselves as the medium for embedding optical sensing fibers. The structural layers act as an intermediary that naturally positions and protects the optical fibers during manufacturing, eliminating the need for separate positioning mechanisms or complex assembly procedures.
3Strength
If fibers in adjacent layers are offset by at least 45 degrees, then structural strength and anomaly detection capability are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent introduces deliberate asymmetric offset patterns between fiber layers, with each layer's fibers positioned at least 45 degrees relative to adjacent layers. This asymmetric arrangement enhances both structural strength through distributed load paths and sensing capability through multi-angle anomaly detection, while the fixed angular relationship simplifies manufacturing by providing clear positioning guidelines.
