Solution Overview
Problem
Existing brewing methods for beverages like coffee and tea face challenges in achieving full flavor extraction, ease of use, and cleanliness, particularly in controlling brewing parameters and efficiently separating brewing media from the beverage.
Innovation Solution
A brewing device comprising a frame, a lift, a brewing canister with a filter, and a receiving beaker that allows for full mixing of brewing fluid and media, with a vacuum mechanism to draw the brewed fluid through the filter into the beaker while retaining the media, and a design that facilitates easy cleaning and parameter control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If coffee grounds and hot water are mixed in a container for thorough flavor absorption (French Press technique), then flavor extraction is improved, but the brewing process becomes time-consuming and difficult to control
Solution Approach 1:
The device pre-sets the brewing parameters including water temperature control, brewing time timing mechanisms, and automatic vacuum initiation. The system is prepared in advance with pre-measured coffee grounds capacity and pre-configured vacuum sealing mechanisms, eliminating the need for manual timing and temperature monitoring during the brewing process.
Solution Approach 2:
The device incorporates automatic feedback mechanisms including timers that monitor brewing duration, temperature sensors that maintain optimal water temperature, and pressure sensors that detect when vacuum sealing is complete. These feedback systems automatically adjust or terminate the brewing process to achieve optimal flavor extraction within a controlled time frame.
2Quantity of substance
If coffee grounds and hot water are mixed for thorough flavor absorption, then flavor extraction is improved, but parameter control (water temperature, grounds size, ratio) becomes difficult
Solution Approach 1:
The device integrates multiple functions into a single unit: water heating and temperature control, brewing time timing, vacuum sealing, and filtration. This multi-functionality consolidates the complex parameters of French Press brewing into an automated system that handles temperature, time, and separation uniformly, making the process as easy as adding coffee grounds and pressing a button.
Solution Approach 2:
The device automatically controls and adjusts critical brewing parameters including maintaining optimal water temperature through heating elements and thermostats, controlling the brew time through automated timers, and managing the water-to-coffee ratio through pre-configured reservoir capacities. These parameter changes are managed automatically rather than requiring manual control.
3Quantity of substance
If French Press equipment is used for thorough mixing, then flavor extraction is improved, but cleaning becomes difficult or inconvenient
Solution Approach 1:
The device is designed with segmented, modular components including a removable brewing chamber, detachable filter assembly, and separable vacuum mechanism. Each component can be independently removed and cleaned, preventing the cleaning difficulties associated with traditional French Press where the plunger and filter are difficult to disassemble and clean thoroughly.
Solution Approach 2:
The filter and brewing media are designed to be easily extracted from the brewing chamber. The vacuum sealing mechanism separates the brewed coffee from the coffee grounds through a removable filter assembly, allowing the filter and chamber to be easily rinsed and cleaned without disassembling complex mechanisms, thus simplifying the cleaning process while maintaining thorough flavor extraction.
4Ease of operation
If manual removal of tea bag is required, then brewing control is simplified, but it is difficult to judge optimal brewing time
Solution Approach 1:
The device pre-configures the brewing time through an automated timer system that is set before brewing begins. The timer automatically counts down the optimal brewing duration and triggers the vacuum sealing and separation process at the precise moment brewing should end, eliminating the need for manual judgment of brewing time while maintaining operational simplicity.

Function Achieved in This Case
Enables thorough flavor extraction, easy operation, and efficient separation of brewing media from the beverage, while allowing for precise control of brewing parameters and convenient cleaning.
Implementation Method 1
moving the lift so that the receiving beaker is moved toward the second position will create a vacuum between the filter and the receiving beaker, and the vacuum will draw brewed fluid from the brewing chamber through the filter and into the receiving beaker

AI summary
A beverage brewing device is configured to brew beverages such as coffee and tea. A brewing canister having a filter at a bottom end is held partially within a receiving beaker, and a seal is created between the canister outer surface and the beaker inner surface. Brewing media such as coffee grounds and brewing fluid such as hot water are added to the canister, mixed, and allowed to brew. At a desired time, the receiving beaker is moved relative to the brewing canister so that the brewing canister is partially removed from the receiving beaker. As such, a vacuum is formed between the bottom end of the brewing canister and the receiving beaker. The filter stops brewing media from flowing into the receiving beaker, but the vacuum draws the brewed beverage through the brewing media and filter and into the receiving beaker.
