Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human remains bags lack effective filtration and replacement mechanisms for air purifying canisters, leading to potential escape of harmful gases and liquids during extended storage and transport, necessitating new bags when canisters expire.
Innovation Solution
A human remains bag with a one-way filtration unit and coupling for air purifying canisters, allowing for secure containment and replacement of canisters without releasing trapped gases and liquids, featuring a plunger and spring mechanism for fluid control and a secure thread connection for fluid-tight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional human remains bags are used without replaceable filtration units, then the bag structure remains simple, but harmful gases and liquids cannot be effectively contained during extended storage
Solution Approach 1:
The bag is divided into functional segments: a body portion for containment and a separate filtration unit with replaceable canister. This segmentation allows the filtration system to be upgraded or replaced independently without redesigning the entire bag structure, thereby improving containment reliability while maintaining structural simplicity.
Solution Approach 2:
A coupling mechanism acts as an intermediary between the bag body and the filtration unit. This coupling includes a valve that mediates fluid flow control, allowing the system to maintain simplicity while enabling effective containment through the intermediate filtration component.
2Duration of action of stationary object
If air purifying canisters are made replaceable with coupling mechanisms, then continuous filtration is enabled, but the device complexity increases
Solution Approach 1:
The filtration system transitions from a static, permanent canister to a dynamic, replaceable configuration. The coupling mechanism with its valve system allows the canister to be dynamically connected and disconnected, enabling extended filtration duration through replacement while keeping the added complexity manageable through standardized interfaces.
Solution Approach 2:
The system enables discarding of depleted canisters and recovery/replacement with fresh ones. The coupling mechanism facilitates this cycle by providing a secure but replaceable connection, thereby extending the overall filtration duration without requiring overly complex permanent systems.
3Reliability
If one-way flow valves are integrated into the coupling, then fluid control is improved, but the manufacturing complexity increases
Solution Approach 1:
The one-way flow valve is merged with the coupling mechanism itself rather than being a separate component. This integration improves fluid control reliability by ensuring proper flow direction while simplifying manufacturing compared to assembling multiple separate valve and coupling parts.
4Adaptability or versatility
If expandable connectors are added to adjust surface area, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The connector transitions from a fixed configuration to a dynamic, expandable structure. This allows the surface area to be adjusted based on needs while maintaining relatively simple construction through collapsible design elements that can be easily deployed or stored.
