Double-Walled Vacuum Growler for Temperature and Carbonation Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers, such as growlers, face challenges in maintaining the temperature of beverages and minimizing agitation during filling and dispensing, which leads to carbonation loss and oxygen introduction, affecting the taste and freshness of the beer.
Innovation Solution
A double-walled vacuum vessel with a horizontally offset dispensing opening and a secure handle assembly, featuring a tethered cap to prevent loss, provides improved insulation and reduced agitation during pouring and filling, while allowing for easy handling and carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional growler is used for transporting beer, then the vessel can carry a larger volume of beer, but the temperature of the beverage cannot be maintained and the beer is subject to agitation during filling and dispensing
Solution Approach 1:
The growler is divided into two separate walls (inner wall and outer wall) with a vacuum space between them, creating a thermal insulation system that maintains beverage temperature while preserving the large capacity needed for beer transport
Solution Approach 2:
A vacuum layer acts as an intermediary between the inner and outer walls, providing thermal insulation that prevents heat transfer while maintaining the structural integrity and capacity of the growler
2Device complexity
If the dispensing opening is centered at the top of the growler, then the structure is simple, but filling and dispensing operations cause significant agitation that releases carbon dioxide and mixes in oxygen
Solution Approach 1:
The dispensing opening is positioned off-center on the side wall rather than at the centered top opening, creating an asymmetric configuration that allows beer to be filled and dispensed through a lower opening, thereby reducing agitation and preserving carbonation while maintaining structural simplicity
3Ease of operation
If the growler has a handle for easy handling during dispensing, then the ease of operation improves, but the handle may protrude horizontally beyond the outermost diameter making it difficult to carry
Solution Approach 1:
The handle is strategically positioned at a specific location on the growler body where it provides adequate leverage for dispensing operations while its dimensions and placement ensure it does not protrude beyond the outermost diameter, optimizing both handling and portability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The double-walled vacuum vessel effectively maintains beverage temperature and minimizes agitation during dispensing, preserving the carbonation and freshness of the beer by reducing disturbance and oxygen introduction, while being easy to handle and transport.
Implementation Method 1
a sealed gap space formed between the inner wall and the outer wall. The sealed gap space is in a vacuum state
Implementation Method 2
The double wall converges to form a top opening into the interior compartment. A vacuum is formed in a gap within the double wall
