Innovation Solution
A magnetic tea-brewing device with a simple structure featuring a separation mechanism using a stressed block and separation magnet, allowing the tea strainer to be attracted and released by adjusting the relative position between the magnet and a magnetically attractive metal block, enabling easy adjustment of tea concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic attraction mechanism and push mechanism are both provided at the upper lid, then the tea strainer can be attracted and pushed, but the structure becomes complex and production cost increases
Solution Approach 1:
The patent extracts the push mechanism from the upper lid and relocates it to the cup body bottom. This separation allows the upper lid to retain only the magnetic attraction mechanism, significantly simplifying the overall structure while maintaining both attraction and push functions. The push rod is now a simple component at the cup bottom rather than a complex mechanism integrated into the lid.
Solution Approach 2:
The patent introduces a magnetically attractive metal block as an intermediary component. This metal block is attracted by the magnet on the upper lid, and when pushed by the push rod at the cup bottom, it transmits the pushing force to the tea strainer. This intermediary approach allows the push function to be achieved through a simple rod rather than a complex mechanism.
2Reliability
If an elastic sealing cap is adopted for the push rod, then sealing is achieved, but process difficulty and production cost increase
Solution Approach 1:
The patent applies a coating layer on the surface of the push rod that provides sealing properties. This coating approach creates a homogeneous sealing surface that is simpler to manufacture than an elastic sealing cap. The coating can be applied through standard coating processes, reducing both production complexity and cost while maintaining reliable sealing.
3Reliability
If the tea strainer is kept attracted to the cup lid, then the tea strainer is separated from water, but tea cannot be brewed
Solution Approach 1:
The patent creates a dynamic system where the tea strainer can switch between two states: attracted to the cup lid for separation, and pushed down to the cup bottom for brewing. The push rod mechanism allows easy transition from the attracted state to the brewing state by applying a simple pushing force, making the brewing process controllable and convenient.
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 device allows for convenient adjustment of tea concentration by controlling the attraction and release of the tea strainer, simplifying the brewing process and reducing production costs while maintaining effective sealing.
Implementation Method 1
the tea strainer is provided with a magnetically attractive metal block, the magnetically attractive metal block of the tea strainer is configured to be attracted by the separation magnet
Implementation Method 2
the stressed block under stress changes a relative position between the separation magnet and the cup lid, the stressed block is stressed when brewing tea, such that the separation magnet moves away from the magnetically attractive metal block
Implementation Method 3
an attraction force to the magnetically attractive metal block from the separation magnet is decreased, thus the tea strainer falls down to the bottom of the cup body due to gravity when the attraction force is less than a gravity of the tea strainer
