Solution Overview
Problem
Existing automatic drip coffee machines lack precise control over the temperature and flow rate of hot water, which affects the quality of drip coffee, and they also fail to precisely control the drip pattern of hot water.
Innovation Solution
The automatic drip coffee machine incorporates a dual-boiler system comprising a high-temperature water boiler and a medium-temperature water boiler, along with a drip system featuring multiple drip nozzles and transfer modules that allow for precise control over the temperature, flow rate, and drip pattern of hot water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single boiler is used in automatic drip coffee machines, then the device complexity is reduced, but the temperature control precision deteriorates
Solution Approach 1:
The patent divides the single boiler system into multiple independent boilers (first boiler for high temperature, second boiler for medium temperature) to simultaneously achieve precise temperature control for different coffee brewing stages while maintaining manageable system complexity through modular design
2Device complexity
If one boiler is used for all brewing stages, then the device complexity is reduced, but the extraction quality deteriorates due to temperature variation
Solution Approach 1:
The patent applies local quality by providing different temperature conditions (high temperature from first boiler, medium temperature from second boiler) for different brewing stages, ensuring optimal extraction quality for each stage while keeping the overall heating system configuration manageable
3Device complexity
If manual water pouring is used, then the device complexity is reduced, but the productivity deteriorates due to time-consuming manual operation
Solution Approach 1:
The patent implements self-service by equipping the water delivery system with automatic control capabilities that enable the system to perform water pouring operations autonomously according to preset parameters, significantly improving coffee brewing efficiency while maintaining relatively simple device structure
4Device complexity
If simple water delivery control is used, then the device complexity is reduced, but the manufacturing precision deteriorates in controlling drip pattern
Solution Approach 1:
The patent applies dynamics by making the water delivery control system adjustable and reconfigurable, allowing precise control of drip patterns and flow rates that can be modified according to different coffee types and brewing requirements, achieving high manufacturing precision without excessive device complexity
