Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing appliances for cooling drinks are inefficient, either diluting the drink with ice, requiring frequent manual refilling of cooling liquids, having limited heat exchange surface area, consuming excessive energy, or being too heavy and expensive for domestic use.
Innovation Solution
A portable appliance with a container and a removable cooling body that uses a motor to circulate the liquid through a closed circuit, enhancing heat exchange and allowing pre-cooling of the cooling body for efficient and rapid cooling without active heat removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a tank is mounted above a heat exchanger for gravity-based cooling, then the device structure is simple, but the cooling liquid must be frequently refilled and the cooling effect is insufficient
Solution Approach 1:
The patent transforms the static gravity-based cooling system into a dynamic pumped circulation system. A pump circulates the drink through the heat exchanger repeatedly, creating continuous motion and repeated heat exchange contacts, which dramatically improves cooling efficiency without requiring frequent refilling of cooling liquid.
Solution Approach 2:
The pumped circulation system ensures continuous heat exchange action by constantly moving the drink through the heat exchanger. This continuous circulation allows the cooling process to proceed efficiently without interruption, unlike the batch-style gravity system that requires refilling.
2Device complexity
If a refrigerant gel container is used for passive cooling, then the device is simple and portable, but the heat exchange surface area is small and cooling is slow
Solution Approach 1:
The system makes the drink dynamic by pumping it through the heat exchanger, increasing the rate of heat transfer. The continuous circulation ensures that fresh portions of the drink constantly contact the cooling surface, maximizing the effective heat exchange area utilization and cooling speed.
3Temperature
If electrical means are used for simultaneous cooling and mixing, then the cooling effect is strong, but the energy consumption is high and the device is heavy
Solution Approach 1:
The patent extracts the active cooling function from the system by using a pre-cooled heat exchanger (cooled in a refrigerator or freezer) instead of active electrical cooling. The pump only needs to provide circulation, not cooling, thereby dramatically reducing energy consumption while maintaining effective cooling through the pre-cooled heat exchange surface.
Solution Approach 2:
The heat exchanger is pre-cooled before use by placing it in a refrigerator or freezer. This preliminary cooling action stores thermal energy in the heat exchanger, which then transfers to the drink during circulation, eliminating the need for continuous electrical power consumption during the actual cooling process.
4Temperature
If ice is added to cool the drink, then the temperature is reduced quickly, but the drink is diluted and taste is affected
Solution Approach 1:
The system separates the cooling function from the drink itself by using a dedicated heat exchanger component that can be pre-cooled independently. This allows the drink to be cooled through heat exchange without direct contact with ice or cooling agents, preventing dilution and preserving the original taste and concentration of the beverage.

AI summary
The invention relates to an appliance (1; 101; 201) for cooling a liquid fit for human consumption, comprising a container (4; 104; 204). At least one motor member (6; 106; 206) located inside the container engages with at least one removable cooling body (10; 110; 210) to guide and pump the liquid fit for human consumption around a closed circuit. The cooling body is designed to optimize the cooling effect by increasing the surface area of the liquid fit for human consumption in contact with the cooling body. To this end it has channels (11, 12; 112) through which the liquid fit for human consumption passes in such a way as to promote heat exchange and so reduce the length of time required to cool the liquid fit for human consumption to a predetermined temperature.
