Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote sensing systems face challenges in accurately quantifying gas concentrations due to environmental factors like wind and temperature variations, which complicate the calibration of gas detection systems, especially when dealing with toxic gases.
Innovation Solution
A self-supporting segmented gas container system, comprising a bladder made of optically transparent material, is used to contain gases for optical detection, which includes a top and bottom layer sealed with a perimeter seam, ribbing for segment definition, and a frame for support, allowing precise optical detection and calibration by controlling internal pressure for rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gases are released into the environment for remote sensing detection, then gas concentration can be measured, but calibration becomes difficult due to drifting gas based on environmental conditions such as wind and varying temperatures
Solution Approach 1:
The gas containment structure is divided into multiple sealed segments or chambers that can be independently controlled. This segmentation allows precise control of gas distribution and concentration within each segment, enabling accurate calibration without environmental interference while maintaining the ability to release gas for remote sensing detection.
Solution Approach 2:
A controlled release mechanism acts as an intermediary between the sealed gas containment and the external environment. This intermediary system allows gas to be released in controlled amounts and locations, enabling calibration measurements while preventing uncontrolled drifting caused by wind and temperature variations.
2Stability of the object's composition
If a sealed gas container is used for optical detection, then optical path stability is improved, but the container requires structural support to maintain shape and prevent deformation
Solution Approach 1:
The gas container utilizes a flexible yet structurally sound membrane or thin film structure that can maintain its shape and optical path stability without requiring rigid internal support structures. This flexible shell design prevents deformation while allowing the container to be lightweight and easy to deploy for remote sensing calibration.
3Measurement precision
If the gas container material is made optically transparent for detection, then optical detection accuracy is improved, but the material must be sufficiently pure to minimize absorptions in the spectral region of detection
Solution Approach 1:
The material composition and optical properties are carefully selected and optimized to match the detection spectral region. By changing or adjusting material parameters such as thickness, composition, and optical transmission characteristics, the container achieves high transparency in the detection wavelength range while maintaining structural integrity and ease of manufacture.
