Portable CO2 Absorption Machine for Aircraft Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current carbon dioxide (CO2) absorption technologies are not portable, large, heavy, and cumbersome, making them unsuitable for use in confined spaces where CO2 levels are increasing, such as in aircraft during dry ice sublimation, posing safety risks to aircrew and limiting dry ice transport capacity.
Innovation Solution
A portable, lightweight carbon dioxide absorption machine (PCDAM) that continuously monitors and reduces CO2 levels using a blower/fan system, CO2 absorbing devices with interchangeable cartridges, and a control system, allowing operation in various environments, including aircraft, without requiring a large footprint or external power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large canisters or cartridges are used for CO2 absorption, then CO2 absorption capacity is improved, but portability and ease of operation deteriorate
Solution Approach 1:
The CO2 absorption system is divided into modular components: a reusable housing unit and replaceable absorbent cartridges. This segmentation allows the absorption capacity to be concentrated in the cartridges while keeping the housing portable and manageable in size.
Solution Approach 2:
The invention changes the physical state and form of the absorbent material from large solid blocks to compressed granular or pellet forms that can be contained in smaller, lighter cartridges while maintaining high absorption capacity.
2Quantity of substance
If large canisters or cartridges are used for CO2 absorption, then CO2 absorption capacity is improved, but device weight increases
Solution Approach 1:
By separating the absorbent material into replaceable cartridges, the system allows users to carry only the lightweight housing and swap cartridges as needed, rather than transporting heavy large-capacity units continuously.
Solution Approach 2:
The absorbent cartridges are designed as disposable or limited-life components that can be easily replaced. This allows the use of lighter materials in the cartridges themselves, with the overall system weight managed through strategic placement and modular replacement rather than permanent heavy construction.
3Reliability
If traditional CO2 absorption technology is used, then CO2 absorption function is achieved, but adaptability to different environments deteriorates
Solution Approach 1:
The reusable housing unit is designed as a universal platform that can accommodate different cartridge types and be deployed in various environments (aircraft cabins, confined spaces, industrial settings). The standardized interface and housing design enable the same basic unit to serve multiple functions and locations.
Solution Approach 2:
The system incorporates adjustable features such as variable airflow controls and adaptable mounting options, allowing the device to be configured for different environmental conditions and application requirements rather than being fixed for a single use case.
