Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time weight and time information are used to provide detailed brewing guidance, then brewing precision is improved, but device complexity increases
Solution Approach 1:
The brewing process is segmented into multiple stages (initial stage, first brewing stage, second brewing stage) with each stage having specific target lines and flow rate thresholds. The display interface is segmented into multiple display blocks that independently show information for different stages, allowing complex brewing guidance to be presented in an organized, manageable way that improves precision without overwhelming the user with complexity.
Solution Approach 2:
The patent introduces an intermediary processing device that receives real-time weight and time information from the electronic scale, calculates flow rates, determines which brewing stage is active, and generates appropriate display instructions. This intermediary layer handles the complex data processing and decision-making, keeping the overall device architecture manageable while still achieving high brewing precision through sophisticated real-time monitoring and guidance.
2Ease of operation
If multiple display blocks and animations are used to guide different brewing stages, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Different display blocks are assigned specific functions for different brewing stages: the first display block shows guidance for the initial stage, the second display block shows guidance for the first brewing stage, and the third display block shows guidance for the second brewing stage. Each block displays only the relevant information for its specific stage, making the interface intuitive and easy to understand while managing complexity through functional specialization.
Solution Approach 2:
The display interface dynamically adapts its content based on the current brewing stage and real-time flow rate conditions. Different animations are displayed depending on whether the flow rate is higher than, equal to, or lower than the threshold - for example, a first animation when flow rate equals the threshold, a second animation when higher, and a third animation when lower. This dynamic behavior provides intuitive real-time feedback that improves ease of operation without requiring permanent complex circuitry for all possible states.
3Manufacturing precision
If real-time feedback on flow rate is provided, then brewing precision is improved, but loss of time in processing information increases
Solution Approach 1:
The brewing guide device receives and processes the brewing parameters in advance, including the target weight, target time, and flow rate threshold for each brewing stage. This preliminary setup allows the device to quickly compare real-time weight and time information against pre-stored reference values during the actual brewing process, enabling rapid flow rate calculations and immediate display updates without time-consuming data retrieval or complex computations during the critical brewing moments.

AI summary
A brewing guide device is provided having a communication device, a processing device, and a display device. The communication device obtains real-time weight information and real-time time information from an electronic scale. In a first brewing stage, the processing device determines whether the flow rate is higher than, equal to or lower than a first threshold according to the real-time weight information and the real-time time information to generate a first display instruction. According to the first instruction, the display device displays a first water line corresponding to the real-time weight information, a first target line corresponding to the first brewing stage, and a first display pattern corresponding to a first display block below the first target line on a display interface, wherein the level of the first water line is lower than or equal to the first target line.
