Fermentation Container Sealing Structure for Carbonic Acid Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fermentation containers for home beer makers face challenges in maintaining optimal temperature and preventing leakage of carbonic acid during the fermentation process, which can lead to suboptimal beer quality and equipment damage.
Innovation Solution
A fermentation container design featuring a flexible container thermally bonded to a container body, with a pressing member made of elastic material that prevents separation of the thermal bonding portion from the bonding portion, ensuring consistent temperature control and preventing carbonic acid leakage by maintaining pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a flexible container is thermally bonded to a bonding portion, then temperature control is improved, but the bonding portion may separate from the thermal bonding portion due to internal pressure, leading to leakage
Solution Approach 1:
The pressing member is pre-installed and pre-compressed between the bonding portion and the flexible container before fermentation begins. This preliminary compression action ensures that the thermal bonding interface is firmly pressed together from the start, preventing separation when internal pressure builds up during fermentation.
Solution Approach 2:
The pressing member acts as a preventive measure against bonding failure. By continuously applying compression force beforehand and throughout the fermentation process, it cushions against the harmful effect of internal pressure that would otherwise cause the thermal bonding portion to separate from the bonding portion.
2Reliability
If the fermentation container is sealed tightly to prevent leakage, then reliability is improved, but temperature uniformity may deteriorate due to heat accumulation
Solution Approach 1:
The pressing member is positioned specifically at the bonding portion where leakage occurs, applying localized compression force only where needed. This localized action prevents leakage at the bonding interface without requiring uniform compression throughout the entire container, thus maintaining temperature uniformity in the fermentation space.
