Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nitrous oxide cartridge systems for whipped cream containers contaminate perishable items with manufacturing waste particles and metal shards, lacking a filter to prevent contamination.
Innovation Solution
A nitrous oxide filter system with an expansion/settling chamber, adapter coupling, and nozzle, which includes a filter media to purify nitrous oxide before it enters a sealable container for preserving perishable goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing nitrous oxide cartridges are used with whipped cream containers, then nitrous oxide can be applied to preserve perishables, but manufacturing waste particles and metal shards contaminate the product
Solution Approach 1:
The patent introduces an intermediary filtering system between the nitrous oxide cartridge and the perishable items. The filter housing with filter media captures manufacturing waste particles and metal shards from the nitrous oxide gas stream, allowing only purified gas to contact the perishables. This intermediary component resolves the contradiction by maintaining preservation effectiveness while eliminating contamination.
Solution Approach 2:
The patent extracts and removes harmful contaminants (manufacturing waste particles and metal shards) from the nitrous oxide gas stream through the filtering system. The filter media selectively separates and retains these harmful particles while allowing the beneficial nitrous oxide gas to pass through, thus resolving the contamination issue while maintaining preservation functionality.
2Object-affected harmful factors
If a filter system is added to purify nitrous oxide, then contamination is prevented, but device complexity increases
Solution Approach 1:
The patent segments the nitrous oxide delivery system into distinct functional components: the original cartridge, the filter housing, the filter media, and the outlet. This segmentation allows each component to perform its specific function independently, making the overall system easier to manufacture, assemble, and maintain while achieving contamination prevention.
Solution Approach 2:
The patent applies filtering functionality locally at the point where nitrous oxide contacts the perishables, rather than requiring system-wide complexity. The filter housing and media are positioned specifically in the gas delivery path, providing contamination prevention only where needed, thus minimizing overall device complexity while achieving the desired protection.

AI summary
A system for preserving perishable items in a sealable container may include a nitrous oxide filter engageable with the sealable container. The nitrous oxide filter may include an expansion/settling chamber, an adapter coupling operatively attached to an inlet of the expansion/settling chamber, a nozzle attached to an outlet of the expansion/settling chamber, and a filter media positioned with the expansion/settling chamber, wherein the filter adapter is configured to engage with an exit nozzle on an existing nitrous oxide cartridge system.
