Solution Overview

Problem

Existing electronic atomization devices lack effective mechanisms to prevent reverse insertion of atomizers into battery poles, which can lead to improper connections and potential damage.

Innovation Solution

Incorporating an atomizer identifier with a chip and peripheral circuit that determines identification voltage and connects via contact structures to read information from the atomizer identification circuit, allowing for correct identification and connection in either insertion manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an anti-reverse-insertion interface is provided on the battery pole to prevent reverse insertion, then connection reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing identification and verification of the atomizer connection mode before enabling normal operation. The identifier chip determines whether an identification voltage is to be provided, and the atomizer identification circuit reads information before the device becomes operational, preventing reverse insertion damage before it occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical anti-reverse-insertion interfaces with an electrical identification system. Instead of using physical asymmetric structures to prevent reverse insertion, the system uses an identifier chip and atomizer identification circuit to detect connection mode electrically and determine whether to enable operation, simplifying the mechanical structure while maintaining reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If resistors indicating flavor information are provided on atomizers, then information identification is achieved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveflavor information identificationVSAvoidmanufacturing precision
Core Design Contradiction:
Loss of informationVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by transitioning from using resistance values (continuous parameter with tolerance issues) to using digital identification codes (discrete parameter with high precision). The atomizer identification circuit reads digital information from the identifier chip, which provides exact flavor identification without being affected by manufacturing tolerances of passive components.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses copying by storing flavor information in the form of digital identification codes in the identifier chip rather than relying on physical resistor values. This digital copy of flavor information can be precisely read and interpreted without the precision limitations of physical component manufacturing.

Inventive Principle:
Principle #26Copying

AI summary

The atomizer identifier is configured to identify an atomizer connected to a battery pole. The atomizer includes a first contact structure and an atomizer identification circuit, and the battery pole further includes a second contact structure matching the first contact structure. The atomizer identifier includes: an identifier chip, configured to determine whether to provide an identification voltage; and a peripheral circuit, configured to connect the identifier chip and the second contact structure, for being connected to the atomizer identification circuit via the second contact structure and the first contact structure of the atomizer connected to the battery pole in a first connection manner or the atomizer connected to the battery pole in a second connection manner, so that the atomizer identification circuit is driven according to the identification voltage determined to be provided by the identifier chip to read information of the atomizer identification circuit to the identifier chip.
