Two-Component Bottle Stopper for Accurate CO2 Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle stoppers for highly carbonated beverages like champagne fail to accurately measure carbon dioxide saturation due to design limitations, leading to potential leakage and inaccurate readings, especially when using aphrometers with insufficient needle length.
Innovation Solution
A two-component bottle stopper comprising a sealing sleeve and outer shell, where the outer shell has a hole to accommodate the upper end wall of the sealing sleeve, allowing for accurate carbon dioxide saturation testing without compromising closure tightness, using polymeric materials with varying elasticity and rigidity for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional stopper design with a seal covering the internal cavity is used, then the closure tightness is maintained, but the carbon dioxide saturation test cannot be accurately performed with aphrometers of insufficient needle length
Solution Approach 1:
The stopper is divided into two separate components: an outer shell and a sealing sleeve. This segmentation allows the upper end wall of the sealing sleeve to be accessible through a hole in the outer shell, enabling accurate CO2 saturation testing while maintaining closure tightness through the separate sealing sleeve component.
Solution Approach 2:
The sealing function is extracted from the outer shell and placed in a separate sealing sleeve. This allows the upper end wall of the sealing sleeve to be accessible for testing purposes while the outer shell maintains the overall closure structure and tightness.
2Measurement precision
If a stopper with a blind lower end of the sealing part is used, then the structure is simplified, but accurate saturation parameters cannot be obtained and carbon dioxide leakage may occur
Solution Approach 1:
By segmenting the stopper into an outer shell and a separate sealing sleeve with an open lower end, the design enables accurate saturation measurements while maintaining structural integrity. The sealing sleeve's open lower end allows aphrometer needles to access the CO2 saturation area without compromising the overall closure tightness.
3Reliability
If a two-component stopper with separate seal is used, then the closure tightness is improved, but the impossibility to obtain saturation parameters with insufficient needle length remains
Solution Approach 1:
The sealing function is extracted from the outer shell into a separate sealing sleeve, making the upper end wall accessible through a hole in the outer shell. This enables CO2 saturation testing with aphrometers of insufficient needle length while maintaining closure tightness through the dedicated sealing sleeve.
Solution Approach 2:
The hole in the outer shell acts as an intermediary, allowing the aphrometer needle to access the CO2 saturation area through the sealing sleeve's upper end wall without compromising the closure tightness maintained by the separate sealing sleeve component.
