Solution Overview
Problem
Most people find it difficult to brew high-quality pour-over coffee due to lack of understanding of brewing parameters' effect on flavor, inconsistent control of brewing parameters in manual processes, and the time-consuming nature of hand-brewing.
Innovation Solution
A brewing machine with a liquid source, heating device, dispensing outlet, and motion device that moves according to programmed brewing patterns, allowing precise control of brewing parameters through a programmable sequence, including fluid temperature, dispensation rate, and motion trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pour-over coffee brewing is done by hand, then the brewing process is simple and easy to operate, but the brewing parameters cannot be accurately controlled and the flavor is inconsistent
Solution Approach 1:
The brewing process is segmented into multiple stages (bloom stage, main brewing stage, etc.) with each stage having specific motion trajectories, dispensation rates, and temperatures. The motion device is divided into first and second transmission mechanisms that independently control different aspects of the dispensing outlet movement, allowing precise control of brewing parameters while maintaining a relatively simple overall structure.
Solution Approach 2:
The dispensing outlet is made dynamic through the motion device, which moves it along predetermined trajectories during the brewing process. This dynamic positioning allows accurate control of water flow paths and contact areas with coffee grounds, improving brewing parameter control without requiring complex manual operations.
2Productivity
If pour-over coffee brewing is done by hand, then the equipment is simple, but the process is time-consuming and inconvenient
Solution Approach 1:
The motion trajectories and brewing parameters are predetermined and programmed in advance. The first and second transmission mechanisms are pre-configured to move the dispensing outlet along specific paths at specific rates, eliminating the need for real-time manual adjustments and reducing brewing time while maintaining consistency.
Solution Approach 2:
The brewing machine performs the brewing process automatically once initiated. The motion device self-regulates the dispensing outlet position and movement, and the system automatically controls water flow and temperature, freeing the user from continuous manual intervention and improving brewing efficiency.
3Reliability
If multiple brewing parameters are controlled precisely, then the flavor quality is improved, but the device complexity increases
Solution Approach 1:
The control system is segmented into independent modules: the first transmission mechanism controls one aspect of motion, the second transmission mechanism controls another aspect, the heating device controls temperature, and the pump controls dispensation rate. This modular segmentation allows precise control of multiple brewing parameters while keeping each individual component relatively simple and manageable.

AI summary
A brewing machine includes a liquid source, a dispensing outlet, and a motion device for moving the dispensing outlet according to at least one brewing pattern. The motion device includes a first transmission mechanism and a second transmission mechanism, the first transmission mechanism moves the second transmission mechanism to allow the second transmission mechanism to have a first motion trajectory, the second transmission mechanism moves the dispensing outlet to allow the dispensing outlet to have a second motion trajectory, and the first motion trajectory and the second motion trajectory have a substantially same shape.
