Tea making appliance with filter assembly
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
1Object-affected harmful factors
If no filter assembly is used in the tea maker, then the device complexity is reduced, but particulate and lime scale deposits enter the brewing beverage
Solution Approach 1:
The filter assembly is segmented into distinct functional components: a filter plate with filtering surface, an articulating mechanism with pivot points, and a biasing member. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the added complexity.
Solution Approach 2:
The filter plate is designed with articulating capability, allowing it to move between extended and retracted positions through pivot points. This dynamic design enables the filter to adapt to different operational states (filtering vs. cleaning) while maintaining effective particulate removal during brewing.
2Reliability
If the filter plate is fixed in extended position, then filtering effectiveness is improved, but the filter cannot be cleaned or maintained
Solution Approach 1:
The filter plate incorporates articulating movement through pivot points, enabling it to transition between extended (filtering) and retracted (cleaning) positions. This dynamic mechanism maintains filtering reliability when extended while enabling easy access for cleaning and maintenance when retracted.
Solution Approach 2:
The biasing member automatically returns the filter plate to the extended position after manual retraction for cleaning, reducing the need for complex control mechanisms. The system self-regulates between operational states through the spring-loaded return mechanism.
3Reliability
If the filter plate is constantly engaged with the vessel inner surface, then filtering performance is maintained, but the filter assembly structure becomes more complex
Solution Approach 1:
The filter assembly uses a spring-loaded biasing member that provides continuous gentle pressure to keep the filter plate engaged with the vessel inner surface. This elastic mechanism maintains consistent filtering performance through automatic pressure application without requiring complex active control systems.
Solution Approach 2:
The biasing member automatically maintains filter plate engagement with the vessel surface through its spring-loaded design, providing self-regulating pressure without external control. This passive mechanism ensures consistent filtering performance while minimizing structural complexity compared to active control systems.
4Strength
If a spring-loaded biasing mechanism is added to the filter assembly, then the filter plate engagement with vessel surface is improved, but the device complexity increases
Solution Approach 1:
The spring-loaded biasing member provides self-regulating engagement force between the filter plate and vessel surface. The spring mechanism automatically adjusts to maintain optimal contact pressure without requiring external control systems, providing reliable engagement while keeping the added structural complexity minimal.
Solution Approach 2:
The biasing member uses a simple spring mechanism that can be easily replaced if needed, rather than a complex adjustable or controlled system. This approach prioritizes reliability and ease of replacement over minimizing structural complexity.
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 prevents lime scale deposits from entering the pouring path, providing a clean and sterile brewing experience by ensuring the filter plate consistently engages with the inner surface of the vessel.
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
Implementation Method 2
The filter plate is configured to contact an inner surface of the vessel when the filter plate is in the extended position for filtering a brewed tea mixture as the mixture is poured through the upper opening 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.
