Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are used to adjust smoke size and switch lighting effects, then the device structure is simple, but the operability is poor and user needs are not met
Solution Approach 1:
The patent replaces traditional mechanical buttons with a movable part (sliding or rotating component) coupled with a sensing module using magnets and a Hall sensor. This substitution transforms the mechanical button-pressing interface into a more sophisticated mechanical-magnetic sensing system, improving operability through tactile feedback and playful interaction while maintaining a relatively compact device structure.
Solution Approach 2:
The patent introduces a Hall sensor and magnets as intermediary elements between the user's manual operation and the control system. The movable part interacts with magnets to generate magnetic field changes, which the Hall sensor detects and converts into control signals. This intermediary mechanism enables seamless function switching and improved user interaction without requiring direct electrical contacts or complex circuitry exposed to the user.
2Adaptability or versatility
If a movable part with sensing module is used to control functions, then operability and user experience are improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal control mechanism where a single movable part with magnetic sensing can perform multiple functions: adjusting smoke size, switching lighting effects, and controlling other device functions. The Hall sensor detects the position or movement of the movable part relative to magnets, generating control signals for various functional modules. This multi-functional approach allows one mechanical component to replace what would traditionally require multiple separate controls, thereby improving adaptability while limiting the increase in overall device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user operability and provides a playful experience while ensuring efficient function switching and stress relief through tactile feedback, maintaining smoke quality and extending atomizer life.
Implementation Method 1
The Hall sensor conducts under an action of the magnetic field and feeds back the control signal to the control module
Implementation Method 2
when the first magnets move to the position opposite to the second magnets, the first magnets cooperate with the second magnets to generate a magnetic field

AI summary
An electronic cigarette includes a main body, a control module, atomizers, a functional module, a sensing module, and a movable part being capable of sliding or rotating on the main body. The functional module includes at least one of a lighting module, driving modules and a reminder module. The lighting module, the driving modules and the reminder module are all electrically connected to the control module. The atomizers are electrically connected to the control module through the driving modules. The sensing module is used for feeding back a control signal to the control module when the movable part slides or rotates. According to the control signal fed back by the sensing module, the control module switches the functional module, adjusts power output by the driving modules to the atomizers, switches a lighting effect of the lighting module, or switches a working mode of the reminder module.
