Electronic Cigarette Power Adjustment via Atomizer Connection

Solution Overview

Problem

Automatic small-sized electronic cigarettes lack the ability to adjust output power, resulting in a single fixed power setting that fails to meet diverse user needs.

Innovation Solution

An electronic cigarette system with a detachable atomizer and battery device, featuring a controller and indication module that allows users to select output power by connecting and disconnecting the atomizer, using pre-stored correspondences between indication signals and output powers, enabling power adjustment without physical buttons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If buttons are added to the battery device for power adjustment, then the user can select different output powers, but the device complexity and size increase

Engineering Contradiction:

Improvepower selection capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power adjustment function is extracted from the battery device by utilizing the connection/disconnection action of the atomizer itself. The controller detects the connection state of the atomizer and automatically adjusts output power based on pre-stored correspondences, eliminating the need for separate adjustment buttons on the battery device.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The atomizer serves dual purposes: both as the vaporization component and as the power adjustment interface. By detecting whether the atomizer is connected or disconnected, the system allows users to adjust power settings through the atomizer's connection state alone, making the atomizer self-serving for both its primary function and power control function.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If buttons are added to the battery device for power adjustment, then the user can select different output powers, but the device size increases

Engineering Contradiction:

Improvepower selection capabilityVSAvoiddevice size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The power adjustment function is extracted from the battery device by utilizing the connection/disconnection action of the atomizer itself. The controller detects the connection state of the atomizer and automatically adjusts output power based on pre-stored correspondences, eliminating the need for separate adjustment buttons on the battery device.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The connection interface of the atomizer is given multiple functions: it serves both as the electrical connection for power delivery and as the power level selection mechanism. The controller distinguishes between different connection states (connected/disconnected) to determine the desired output power, making the same physical interface serve dual purposes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Volume of moving object

If no buttons are provided on the battery device, then the device maintains miniaturization and simplicity, but the user cannot adjust output power

Engineering Contradiction:

Improvedevice sizeVSAvoidpower selection capability

AI summary

An electronic cigarette and a method for adjusting the power thereof. The electronic cigarette comprises an atomizer (1) and a battery device (2). The battery device (2) comprises a housing, and a controller (21) and a power output module (22) inside the housing. The atomizer (1) is detachably connected to the battery device (2). The housing is provided with an indication module (23). The controller (21) is electrically connected to the indication module (23) and the power output module (22), separately. The controller (21) controls the indication module (23) to alternately output different indication signals, determines, when it is detected that the atomizer (1) is connected to the battery device (2), target output power corresponding to a current indication signal of the indication module (23) according to pre-stored correspondences between the indication signals and output power, and controls, when a suction signal is detected, the power output module (22) for output at the target output power.
