Solution Overview

Problem

Traditional electronic cigarettes are prone to accidental separation of the atomizer from the base, which can lead to misoperation or ingestion by children, posing safety and reliability issues.

Innovation Solution

An electronic cigarette design featuring a locking device between the atomizer and base, controlled by a control device and information collecting device, which requires a verification signal for unlocking, ensuring secure and reliable operation by preventing unauthorized separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the atomizer is plug connected or spirally connected with the base, then the ease of manufacture is improved, but the reliability deteriorates due to accidental separation and misoperation by children

Engineering Contradiction:
Improveease of manufactureVSAvoidreliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The locking device is activated in advance through a verification mechanism (password, fingerprint, or other verification signals) before allowing the atomizer to be separated from the base. This preliminary verification action prevents unauthorized or accidental separation by children, while still allowing legitimate users to separate the components when needed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a locking device with verification mechanism is added, then the reliability is improved by preventing unauthorized separation, but the device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control device serves multiple functions: it controls the atomizer's operation, manages the locking device, and processes verification signals. By making the control device multi-functional, the patent avoids adding separate dedicated components for each function, thereby limiting the increase in device complexity while still achieving reliable protection against unauthorized separation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If the atomizer is securely locked to the base, then the safety is improved by preventing ingestion by children, but the ease of operation deteriorates due to restricted separation

Engineering Contradiction:
ImprovesafetyVSAvoidease of operation
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The locking mechanism transitions from a static locked state to a dynamic state where it can be unlocked through verification. The locking device adapts its state based on verification signals: it remains locked to prevent children from separating the atomizer, but unlocks to allow authorized users to separate the components for cleaning or replacement, thus balancing safety with ease of operation.

Inventive Principle:
Principle #15Dynamics
