Tea Maker Articulating Filter Assembly for Lime Scale Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tea makers lack an effective mechanism for filtering brewed tea as it is poured, leading to the presence of particulate and lime scale deposits in the beverage.
Innovation Solution
A tea maker with a spring-loaded articulating filter assembly that includes a filter plate operable between extended and retracted positions, biased towards the extended position to contact the inner surface of the vessel, ensuring that the brewed tea mixture is filtered as it is poured through the spout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a filter assembly is added to filter brewed tea, then the purity of the tea is improved, but the device complexity increases
Solution Approach 1:
The filter assembly is integrated with the lid assembly, combining two functional components into a single unit. The filter plate is positioned within the lid assembly structure, merging the filtering function with the lid's existing form factor, thereby adding purification capability without proportionally increasing overall device complexity
Solution Approach 2:
The biasing member automatically maintains the filter plate in the extended filtering position against the vessel inner surface without requiring manual intervention. The spring-loaded mechanism self-regulates to ensure consistent contact and filtering action, eliminating the need for additional control systems or manual adjustment mechanisms
2Reliability
If a spring-loaded filter plate is used to ensure consistent contact, then the reliability of filtering is improved, but the device complexity increases
Solution Approach 1:
The biasing member (spring-loaded mechanism) automatically maintains the filter plate in the extended filtering position against the vessel inner surface without requiring manual intervention. The spring force self-regulates to ensure consistent contact pressure and filtering action, eliminating the need for additional control systems, actuators, or manual adjustment mechanisms
Solution Approach 2:
The biasing member is disposed on the filter assembly rather than being integrated into the vessel or lid structure, extracting the spring-loading function as a separate, dedicated component. This modular approach simplifies the overall design by isolating the complexity to a single, well-defined element rather than distributing it throughout the structure
3Manufacturing precision
If the filter plate is extended to contact the vessel inner surface, then the filtering effectiveness is improved, but the loss of brewed tea increases
Solution Approach 1:
The filter plate is configured to contact only the inner surface of the vessel at specific locations where particulate and lime scale deposits are most likely to accumulate. This localized filtering approach maintains effectiveness while minimizing obstruction to the overall flow path, reducing tea loss compared to a full-surface filter
Solution Approach 2:
The filter plate extends partially into the vessel cavity rather than spanning the entire opening, providing sufficient filtering action for the pouring path while leaving adequate open area for tea flow. The biasing member ensures the filter plate engages enough to capture particulates but not so much as to excessively restrict flow
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively filters particulate and lime scale deposits from the brewed tea, providing a cleaner and more sterile tea brewing experience by ensuring consistent contact between the filter plate and the inner surface of the vessel during pouring.
Implementation Method 1
A biasing member is disposed on the filter assembly and is configured to bias the filter plate towards the extended position against the inner surface of the vessel

AI summary
A tea maker includes a brewing unit which defines a vessel having an upper opening with a spout disposed thereon. A lid assembly is removeably received on the upper opening of the vessel and includes a steeping tube. The steeping tube extends downwardly from the lid assembly into the vessel when the lid assembly is received on the upper opening of the vessel. An articulating filter assembly is coupled to the lid assembly and includes a filter plate that is operable between an extended position and a retracted position. The filter plate is configured to contact an inner surface of the vessel when the filter plate is in the extended position. A biasing member is configured to bias the filter plate towards the extended position for filtering a brewed tea mixture as the mixture is poured through the upper opening of the vessel.
