Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage brewing methods are inefficient and time-consuming, particularly for producing high-quality, ultra-premium coffee and tea, with no significant innovations emerging in over 80 years, and existing vacuum brewing processes do not involve brewing within a vacuum chamber.
Innovation Solution
A beverage brewing apparatus and method that utilizes a sealed vacuum chamber to brew coffee and tea, employing a vacuum source to reduce pressure and separate liquids from solids, allowing for quick and efficient brewing or infusing of beverages using hot or cold water, with adjustable vacuum cycles and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional brewing methods are used, then brewing process is simple and equipment is basic, but brewing time is long and efficiency is low
Solution Approach 1:
The patent applies vacuum pressure (pneumatic principle) to accelerate the brewing process. A vacuum chamber creates negative pressure to force rapid extraction of coffee solids into water, reducing brewing time from minutes to seconds while maintaining equipment complexity at an acceptable level through integrated vacuum pump design.
Solution Approach 2:
The patent utilizes phase transition of water (liquid to vapor and back) under vacuum conditions. Water rapidly evaporates and condenses in the vacuum chamber, creating turbulent mixing that dramatically accelerates extraction efficiency, enabling ultra-fast brewing without proportionally increasing equipment complexity.
2Manufacturing precision
If cold brewing method is used, then extraction quality is optimal, but brewing time is too long (12-24 hours)
Solution Approach 1:
The patent uses vacuum pressure to replace the 12-24 hour cold brewing process. By applying negative pressure, the system forces rapid dissolution and extraction of coffee solids, achieving optimal extraction quality in seconds rather than hours, thus eliminating the time loss associated with traditional cold brewing.
Solution Approach 2:
The patent changes the pressure parameter from atmospheric to vacuum conditions, which fundamentally alters the extraction kinetics. This parameter change enables the system to achieve cold brewing quality extraction without the extended time requirement, resolving the contradiction between extraction quality and brewing time.
3Productivity
If vacuum brewing is implemented, then brewing time is reduced and efficiency is improved, but equipment complexity and cost increase
Solution Approach 1:
The patent designs the vacuum chamber to serve multiple functions: it creates the vacuum environment for rapid extraction, contains the phase transition process, and facilitates easy cleaning. This multi-functionality reduces overall equipment complexity by consolidating several functions into a single integrated component.
Solution Approach 2:
The patent employs a removable lid and flexible sealing mechanisms that simplify the vacuum chamber structure. These design choices reduce equipment complexity by using simple, maintainable components rather than complex rigid structures, making the vacuum system more accessible and cost-effective.
4Loss of time
If rapid extraction is achieved through vacuum, then brewing time is short, but separation of liquid from solids becomes more difficult
Solution Approach 1:
The patent uses pressure differential (pneumatic principle) to facilitate separation. By releasing the vacuum or applying positive pressure, the system forces liquid through the coffee grounds and filter, achieving rapid separation without adding complex mechanical separation devices. The same pressure mechanism used for extraction also enables efficient separation.
