Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors or detectors are used to control the switching of electric terminals, then the control function is achieved, but the cost increases and reliability decreases
Solution Approach 1:
The patent removes sensors and detectors from the system entirely. The switching function is achieved through direct mechanical interaction between the storage cup and electric terminal, eliminating the need for separate sensing components and their associated control circuits.
Solution Approach 2:
The storage cup itself performs the switching function by its own movement. When the storage cup moves to different positions, it directly makes or breaks the electrical connection with the electric terminal, without requiring external sensing or control systems.
2Ease of manufacture
If sensors or detectors are used to control the switching of electric terminals, then the switching function is achieved, but the cost increases
Solution Approach 1:
The patent removes sensors and detectors from the system entirely. The switching function is achieved through direct mechanical interaction between the storage cup and electric terminal, eliminating the need for separate sensing components and their associated control circuits.
Solution Approach 2:
The storage cup combines multiple functions: it stores items and simultaneously serves as the switching mechanism. Its movement directly controls the electrical connection, merging the storage function with the control function in a single component.
3Device complexity
If the second electric terminal is movable between contact and non-contact positions, then the switching function is simplified, but the control mechanism reliability may be affected
Solution Approach 1:
The patent employs magnetic fields (an invisible curved field) to ensure reliable contact between the movable electric terminal and the fixed terminal. The magnetic attraction guarantees consistent electrical connection regardless of minor positional variations, maintaining reliability while allowing mechanical movement.
4Reliability
If magnetic locking mechanisms are used for stable electrical connections, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the locking function with the electric terminal itself. The magnetic locking mechanism is integrated into the terminal structure, so the same component that makes electrical contact also provides the magnetic locking, eliminating the need for separate locking mechanisms.

AI summary
An electronic heating device includes a housing; and a first electric terminal, a second electric terminal, a storage cup, and a heating circuit. Both the first electric terminal and the second electric terminal are disposed in the housing. The second electric terminal is movable between a first position and a second position in a direction toward or away from the first electric terminal respectively. The storage cup is movable in the direction toward or away from the first electric terminal, and the storage cup can drive the second electric terminal to move between the first position and the second position. The heating circuit is used for heating a receiving cavity of the storage cup. The first electric terminal and the second electric terminal are electrically connected to the heating circuit.
