Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation systems fail to prevent thermal shock and minimize heat absorption by cold parts during infusion, leading to thermal dispersion and suboptimal infusion temperatures.
Innovation Solution
An infusing unit with a heated infusion chamber, where a thermal fluid circulates between the chamber wall and an external liner, maintaining a controlled temperature through a programmable external heat source, reducing heat absorption by cold parts and optimizing infusion temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot water is contacted with cold infusion chamber walls, then the beverage preparation process is simple and quick, but thermal shock occurs and heat is absorbed by cold parts leading to suboptimal infusion temperature
Solution Approach 1:
The infusion chamber is preheated by circulating thermal fluid through the hollow space between the chamber wall and external liner before hot water is introduced. This preliminary heating action prevents thermal shock when hot water contacts the chamber walls, maintaining optimal infusion temperature without compromising preparation speed.
2Device complexity
If the infusion chamber walls are cold, then the device structure is simple, but heat is absorbed during infusion reducing beverage quality
Solution Approach 1:
A thermal fluid acts as an intermediary between the external heat source and the infusion chamber wall. The fluid circulates through the hollow space, transferring heat gradually to the chamber walls without requiring direct heating elements inside the chamber, thus maintaining structural simplicity while reducing heat loss during infusion.
3Temperature
If thermal fluid circulation system is added, then infusion temperature is maintained, but device complexity increases
Solution Approach 1:
The thermal fluid circulation system serves multiple functions: preheating the infusion chamber before water injection, maintaining optimal temperature during infusion, and preventing thermal shock. This multi-functionality justifies the added complexity by eliminating the need for separate heating and temperature control systems.
