Smoke Taint Sensing Plug for Wine Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting smoke taint in wine, such as wet chemistry, are time-consuming and inefficient, often resulting in delayed detection and significant financial losses for the wine industry due to the bitter, burnt flavor it imparts to wines exposed to smoke from wildfires.
Innovation Solution
A plug system for wine containers equipped with sensors and filters that detect smoke taint compounds like guaiacol and phenols through gas analysis, eliminating the need for liquid sampling and providing real-time monitoring by using electrochemical gas sensors and selective filters to reduce cross-contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wet chemistry methods are used to detect smoke taint, then measurement precision is improved, but loss of time increases significantly
Solution Approach 1:
The patent replaces wet chemistry methods with electrochemical gas sensors that detect smoke taint compounds in the headspace gas above the wine. This substitution eliminates the need for liquid sampling and laboratory analysis, providing real-time detection while maintaining measurement precision through selective sensors and filters.
Solution Approach 2:
The patent uses the headspace gas as an intermediary medium to detect smoke taint compounds. Instead of directly analyzing the wine liquid, the sensors detect volatile compounds that have evaporated into the gas phase above the wine, enabling rapid non-invasive detection.
2Adaptability or versatility
If multiple sensors detect different substances, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent divides the detection function into separate specialized sensors, each dedicated to detecting a specific substance (guaiacol, 4-methylguaiacol, ethanol, sulfur dioxide). This segmentation allows each sensor to be optimized for its target compound while maintaining overall system manageability through modular architecture.
Solution Approach 2:
The patent applies selective filters to each sensor input, creating localized optimization for each detection channel. Each filter is specifically designed to allow only certain compounds to reach its corresponding sensor, enhancing detection specificity without requiring complex global filtering mechanisms.

Implementation Method 1
A first filter is between the input end and the first sensor, where the first filter selectively allows phenols to pass through
Implementation Method 2
A second filter is between the input end and the second sensor, wherein the second filter selectively allows the second substance to pass through
Implementation Method 3
the input end having a liquid-impermeable membrane that allows gas flow to pass through
Implementation Method 4
A first sensor is in a first sensor chamber inside the housing, the first sensor being configured to detect a smoke taint compound

AI summary
A plug for a container for storing liquid includes a housing and an input end at an end of the housing, the input end having a liquid-impermeable membrane that allows gas flow to pass through. A first sensor is in a first sensor chamber inside the housing, the first sensor being configured to detect a smoke taint compound. A first filter is between the input end and the first sensor, where the first filter selectively allows phenols to pass through. A second sensor is in a second sensor chamber inside the housing, the second sensor being configured to detect a second substance different from the smoke taint compound. A second filter is between the input end and the second sensor, wherein the second filter selectively allows the second substance to pass through.
