Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preserving perishable substances like wine fail to effectively prevent degradation due to oxygen exposure, often requiring complex and expensive systems or introducing contaminants, and lack reliable methods for maintaining a vacuum or consistent gas supply.
Innovation Solution
A system using volumetric displacement between a flowable substance and a preservative gas, with a compressible bladder that can be automatically replenished, ensuring a consistent gas supply without pressurizing the bladder, and maintaining the integrity of the vessel's contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressurized systems are used to maintain preservative gas supply, then gas supply reliability is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the pressurization function from the gas supply system by using a flexible bladder that passively expands and contracts based on pressure differentials during dispensing, eliminating the need for active pressurized gas cylinders or pumps while maintaining reliable preservative gas supply to the vessel
Solution Approach 2:
The system equalizes pressure conditions by allowing the preservative gas to flow freely between the reservoir and the vessel through pressure equalization ports, eliminating pressure differentials that would require complex pressurization mechanisms while ensuring continuous gas supply
2Reliability
If vacuum systems are used to prevent oxygen exposure, then preservation effectiveness is improved, but system complexity and cost increase
Solution Approach 1:
The patent creates a protective inert atmosphere in the vessel by continuously supplying preservative gas that displaces oxygen, achieving effective preservation without requiring vacuum systems or complex sealing mechanisms, as the inert gas layer physically barriers oxygen contact with the liquid
3Reliability
If expandable bladders are used to displace oxygen, then oxygen displacement is improved, but contamination risk increases
Solution Approach 1:
The patent introduces a fluid exchange structure as an intermediary component that mediates between the preservative gas supply and the vessel, providing filtered pathways for gas flow while preventing direct contact between the bladder material and the liquid, thereby reducing contamination risk while maintaining oxygen displacement effectiveness
4Device complexity
If manual refilling of preservative gas is required, then system simplicity is maintained, but time loss and operational complexity increase
Solution Approach 1:
The system implements self-service functionality through an automatic refilling mechanism where the bladder is automatically replenished with preservative gas from a reservoir when the gas level drops, eliminating manual intervention and time loss while maintaining overall system simplicity through passive pressure-driven operation
5Productivity
If preservative gas is supplied under pressure, then gas flow rate is improved, but risk of overpressurization and leakage increases
Solution Approach 1:
The patent employs dynamic pressure regulation where the preservative gas flow rate automatically adjusts based on the dispensing rate of the liquid, with pressure equalization ports allowing the system to adapt to varying flow demands without overpressurization, maintaining optimal gas flow while preventing leakage through continuous pressure balancing

AI summary
An automatic replenishing system (300) for automatically replenishing preservative gas within a compressible bladder (314) for supply to the inner volume of a vessel (200). A compressible bladder (314) has an outer wall and an inner volume. A supply conduit (306) receives preservative gas from a source (304), and a discharge conduit (332) supplies preservative gas to a vessel (200). An inflation detection system (316) detects a first condition wherein the compressible bladder (314) is inflated to a state of inflation and a second condition wherein the compressible bladder (314) is inflated below the state of inflation. A valve system (328) is operative to prevent preservative gas from flowing from the source of preservative gas (304) and into the compressible bladder (314) when the compressible bladder (314) is in the first condition and to permit preservative gas to flow from the source of preservative gas (304) and into the compressible bladder (314) when the compressible bladder (314) is in the second condition.
