Solution Overview
Problem
Liquids in containers degrade when exposed to ambient environments during transport and storage, and existing solutions fail to effectively prevent this degradation and maintain the quality of the liquids.
Innovation Solution
A liquid dispensing device that includes a liquid extraction system, an identification system to determine the type of liquid, and a preservation system to control temperature and atmospheric conditions within the container, preventing exposure to the ambient environment and maintaining the quality of the liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is opened to dispense liquid, then the liquid can be accessed and dispensed, but the liquid is exposed to ambient environment causing degradation
Solution Approach 1:
The patent applies inert atmosphere by injecting nitrogen gas into the container headspace to displace oxygen and create an oxygen-free environment. This prevents oxidation and chemical reactions while allowing the liquid to be dispensed through the needle, resolving the contradiction between ease of dispensing and protection from ambient harmful factors.
Solution Approach 2:
The patent uses nitrogen gas as an intermediary substance that mediates between the ambient environment and the liquid. The gas forms a protective barrier in the container headspace, allowing the liquid to be accessed through the needle without direct exposure to oxygen-containing ambient air, thus preventing degradation while enabling dispensing.
2Reliability
If temperature control is implemented to maintain liquid quality, then liquid degradation is prevented, but device complexity increases
Solution Approach 1:
The patent changes the chemical parameter of the container atmosphere by injecting nitrogen gas to create an oxygen-free environment. This alternative approach to temperature control modifies the atmospheric composition instead, maintaining liquid quality through chemical parameter change rather than thermal parameter control, thereby avoiding the complexity of temperature regulation systems.
3Reliability
If gas is injected into the container to prevent degradation, then liquid quality is maintained, but the device complexity increases
Solution Approach 1:
The patent implements inert atmosphere by injecting nitrogen gas into the container headspace. This creates an oxygen-free environment that prevents oxidation and chemical reactions, maintaining liquid quality. The gas injection system, while adding some complexity, provides a reliable and effective method of preservation that directly addresses the liquid degradation problem.
