Double-Container Tea Brewer Pump for Automated Water Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated tea preparation machines are limited in automation, requiring user intervention for water transfer and often fail to maintain optimal water temperature for flavor extraction, leading to incomplete brewing and suboptimal tea flavor.
Innovation Solution
A double container tea machine with a pump system that automatically transfers boiled water from a first container to a second container once a predetermined temperature is reached, using a bidirectional valve and pusher mechanism to establish fluid communication and control the transfer process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated water transfer mechanism is added, then extent of automation is improved, but device complexity increases
Solution Approach 1:
The system uses a temperature-sensitive valve that automatically opens when water reaches the boiling point, eliminating the need for external control mechanisms. The pump activates automatically based on temperature conditions, creating a self-regulating system that achieves full automation without complex control circuits or user intervention.
Solution Approach 2:
The patent replaces manual mechanical water transfer with an automated pump system controlled by temperature-sensitive mechanisms. The mechanical advantage is gained by using the natural boiling process to trigger valve opening, substituting complex electronic controls with simple thermal-mechanical activation.
2Productivity
If water is transferred immediately after boiling, then productivity is improved, but temperature control precision deteriorates
Solution Approach 1:
The system incorporates temperature sensing that continuously monitors water temperature and provides feedback to control the pump operation. When the water reaches the optimal temperature range, the system activates the transfer mechanism, ensuring precise temperature control while maintaining efficient brewing speed. The feedback loop prevents premature or delayed transfer.
Solution Approach 2:
The patent utilizes changes in water temperature as a control parameter to trigger the transfer process. By monitoring temperature as the key parameter and using it to activate the pump and valve mechanisms, the system achieves both rapid processing and precise temperature control, transforming the physical state change from a problem into a solution.
