Solution Overview
Problem
Conventional beverage extraction devices lack mechanisms for actively controlling temperature during the extraction process, leading to unstable temperature conditions that affect the elution of components, resulting in compromised extraction results and significant hidden costs.
Innovation Solution
A beverage extraction device with a temperature adjustment chamber adjacent to the extraction chamber, using a temperature control medium to maintain or adjust the temperature during the extraction process, allowing for precise control of the elution phenomenon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional extraction devices are used without temperature control, then the device complexity is low, but the temperature stability during extraction deteriorates
Solution Approach 1:
The patent implements a nested structure where an inner extraction chamber is placed inside an outer temperature control chamber. The extraction chamber containing the beverage material is nested within the temperature control chamber that circulates temperature control medium, creating a concentric dual-chamber configuration that provides temperature stability while maintaining relatively simple device structure.
Solution Approach 2:
The device is segmented into two functional chambers: the inner extraction chamber for holding beverage material and the outer temperature control chamber for circulating temperature control medium. This segmentation separates the extraction function from the temperature control function, allowing independent optimization of each while maintaining overall system simplicity.
2Temperature
If preheating is performed by hot water rinsing or water bath heating, then the temperature of hot water can be maintained, but the water consumption and energy loss increase significantly
Solution Approach 1:
The patent performs preliminary temperature control by circulating temperature control medium through the outer chamber before and during the extraction process. This preliminary heating or cooling action maintains the optimal temperature in the extraction chamber from the start, eliminating the need for repeated hot water rinsing or water bath heating that waste water and energy.
Solution Approach 2:
The temperature control system operates autonomously by circulating temperature control medium through the outer chamber, self-regulating the temperature of the inner extraction chamber without requiring external intervention such as manual preheating or continuous hot water addition. The system serves itself by maintaining temperature stability through continuous medium circulation.
3Use of energy by moving object
If the extraction chamber is made of materials with high thermal conductivity, then heat transfer is efficient, but heat loss to the surroundings increases
Solution Approach 1:
The patent introduces temperature control medium as an intermediary substance that circulates in the outer chamber, acting as a thermal mediator between the heat source and the extraction chamber. This intermediary layer provides controlled heat transfer while insulating the extraction chamber from direct heat loss to the external environment, optimizing both heat transfer efficiency and thermal insulation.

AI summary
[Problem] To provide an extractor or dripper capable of maintaining or adjusting the temperature necessary for ideal component extraction during the extraction process of coffee or similar beverages. [Solution] The beverage extraction device 1 comprises an extraction chamber 2, in which the components of the extraction material are extracted by passing a liquid therethrough, and a temperature adjustment chamber 3. The temperature adjustment chamber 3 is provided outside the extraction chamber 2, with an inner side wall 20 or an inner bottom wall 23 serving as the partition. In order to adjust the temperature during the extraction process in the extraction chamber 2, a temperature-controlled temperature control medium is introduced into the temperature adjustment chamber 3 through an inlet 7. As a result, the extraction temperature of the liquid during the extraction process can be maintained or adjusted.
