Solution Overview
Problem
Commercially available tea-making machines face issues with uneven brewing due to complex tea basket raising and lowering mechanisms and pipeline blockages from tea scale buildup, making cleaning difficult.
Innovation Solution
A beverage brewing machine with a kettle body containing a water feeding device that includes a flow guide cover, stirrer, and driving device, where the stirrer is magnetically driven to rotate, reducing stirring space and load, and featuring a brewing device with a flow guide cavity and filtering hole for uniform brewing and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a tea basket raising and lowering mechanism is used for brewing, then the brewing process can be automated, but the structure becomes complicated and brewing becomes uneven
Solution Approach 1:
The patent extracts the tea basket from the traditional raising and lowering mechanism, placing it directly in the brewing chamber where it remains stationary. This eliminates the complex mechanical lifting mechanism while maintaining automated brewing through water circulation and magnetic stirring, thus reducing structural complexity while preserving automation.
Solution Approach 2:
The brewing system is segmented into independent functional components: a stationary tea basket for holding tea leaves, a separate water circulation system for automated water delivery, and a magnetic stirring mechanism for water agitation. This segmentation allows each component to perform its function independently without requiring complex interconnections, simplifying the overall structure.
2Extent of automation
If pipeline pumping is used for water delivery, then automated brewing is achieved, but tea scale and coffee liquid block the pipeline making cleaning difficult
Solution Approach 1:
The patent extracts the water delivery function from a closed pipeline system and replaces it with an open water circulation system. Water is delivered directly to the brewing chamber without passing through narrow pipelines, eliminating the blockage problem while maintaining automated operation. The system uses a water tank and direct flow paths that are easily accessible for cleaning.
Solution Approach 2:
Instead of pumping water through pipelines from a remote reservoir, the system inverts the approach by placing the water tank directly in or near the brewing chamber and allowing water to flow naturally or be circulated locally. This reverses the traditional pipeline architecture, eliminating blockage issues and making the water delivery path easily cleanable.
3Shape
If a fixed guide tube is used in the kettle, then water flow is directed, but tea scale accumulates and blocks the tube
Solution Approach 1:
The patent replaces the fixed guide tube with a dynamic water circulation system that uses movable or removable flow guides. The water flow path is not confined to a single fixed tube but can be redirected or cleaned by removing components. The circulation system allows water to flow in multiple directions, preventing scale accumulation in any single location.
Solution Approach 2:
The water flow guidance system is segmented into removable components rather than a single fixed tube. Flow guides are divided into sections that can be detached and cleaned separately, or the entire water circulation path can be accessed by removing the brewing chamber components, making maintenance straightforward.
