Fermentation Container Sealing Structure for Carbonic Acid Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage makers for making homemade beer lack an efficient and user-friendly fermentation container that maintains optimal temperature and prevents leakage of carbonic acid during fermentation.
Innovation Solution
A fermentation container with a main body, a bonding portion, a connecting portion, a flexible container thermally bonded to the bonding portion, and a pressing member made of elastic material to press the thermal bonding portion, preventing separation and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible container is thermally bonded to the bonding portion to form a fermentation space, then the fermentation container can maintain flexibility and accommodate fermentation expansion, but the thermal bonding may separate due to internal pressure causing carbonic acid leakage
Solution Approach 1:
The pressing member is installed before fermentation to apply continuous pressure on the thermal bonding portion, preventing separation that would occur during fermentation due to internal carbonic acid pressure. This preliminary counter-action ensures the bonding remains intact throughout the fermentation process.
Solution Approach 2:
The pressing member acts as an intermediary component between the rigid container body and the flexible container, mediating the pressure forces during fermentation. It distributes and manages the internal pressure to prevent bonding failure while allowing the flexible container to expand.
2Productivity
If the container portion expands during fermentation, then it can accommodate the fermentation process, but the thermal bonding portion may separate from the bonding portion
Solution Approach 1:
The pressing member is pre-installed to apply continuous pressure on the thermal bonding portion before and during fermentation. This preliminary counter-action prevents the bonding from separating even when the container portion expands to accommodate fermentation.
3Reliability
If a pressing member is added to maintain bonding, then bonding stability is improved, but device complexity increases
Solution Approach 1:
The pressing member is designed to be self-installing by fitting between the container body and the flange portion. It automatically positions itself and applies the necessary pressure without requiring additional complex mechanisms or assembly steps, thus adding minimal complexity while effectively maintaining bonding stability.
