Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices are inadequate for rapidly cooling hot beverages, lacking efficiency and ease of use and cleaning.
Innovation Solution
A beverage chiller assembly comprising a first and second cylinder with high thermal conductivity materials, where the second cylinder fits within the first to create a reservoir for the beverage and a chamber for a chilling medium, enhancing cooling through thermal conduction from both sides and an increased surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single reservoir design is used, then the device structure is simple, but the cooling efficiency is insufficient
Solution Approach 1:
The beverage chiller is divided into two separate reservoirs: a first reservoir for the beverage and a second reservoir for the chilling medium. This segmentation allows independent optimization of each reservoir's function, enabling the beverage to be cooled from both the inside (through the second cylinder wall) and outside (through the first cylinder wall), thereby doubling the effective cooling surface area and significantly improving cooling efficiency.
Solution Approach 2:
The second reservoir (containing the chilling medium) is nested within the first reservoir (containing the beverage). The second cylinder is positioned concentrically within the first cylinder, creating a nested configuration where the chilling medium surrounds the beverage container. This nested arrangement maximizes thermal contact between the two reservoirs while maintaining a compact portable structure.
2Area of stationary object
If cylindrical geometry is used, then the surface area for heat transfer is increased, but the device volume increases
Solution Approach 1:
The nested cylindrical configuration allows the second reservoir to be contained within the first reservoir, utilizing the annular space between the two cylinders for heat transfer. This nesting approach maximizes the heat transfer surface area (the lateral surfaces of both cylinders) while minimizing the overall device volume, as the cooling medium is contained within the beverage reservoir rather than requiring additional external space.

AI summary
A beverage chiller comprising a first cylinder and a second cylinder sized and arranged with the second cylinder disposed within the first cylinder to define a first reservoir between the first cylinder and the second cylinder for receiving a beverage to be chilled. The second cylinder defines an internal chamber for receiving a chilling medium. A cup fabricated from an insulative material receives the cylinders therein with the first cylinder and cup defining a second reservoir for receiving a chilling medium. The first and second cylinders are fabricated from a material having substantial thermal conductivity.
