Solution Overview

Problem

Existing electrical cigarettes with child-proof locks have complex structures that complicate installation and reduce production efficiency, while still posing safety risks as children can accidentally activate the device.

Innovation Solution

An electrical cigarette with a child-proof lock featuring a toggle switch and a toggle assembly with a pressing member and supporting base, where a spring decouples the pushing portion from the poke rod, requiring an external force to connect and activate the switch.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a child-proof lock mechanism is added to prevent children from accidentally activating the switch, then safety is improved, but the device structure becomes more complex

Engineering Contradiction:

ImprovesafetyVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The child-proof lock mechanism is divided into independent functional modules: a pressing member that requires deliberate activation, a push rod that transmits force, and a switch assembly that responds to the force. This segmentation allows each component to be simple while the combination provides safety functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A push rod serves as an intermediary element between the pressing member and the switch. The push rod transmits the activating force from the pressing member to the switch, creating a mechanical linkage that requires intentional action to complete the circuit while maintaining structural simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a complex child-proof lock structure is implemented, then safety is improved, but installation convenience deteriorates and production efficiency decreases

Engineering Contradiction:

ImprovesafetyVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The switch assembly is segmented into discrete components (pressing member, push rod, switch) that can be manufactured separately and assembled through simple insertion and connection operations, enabling efficient production while maintaining safety functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of making the switch itself complex to prevent accidental activation, the solution inverts the approach by adding a simple pressing mechanism that requires deliberate action. The switch remains a standard component, but the activation method is changed to require intentional pressing, simplifying both manufacturing and assembly.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If the pressing member is always connected to the poke rod, then the switch can be easily activated, but children can accidentally turn on the device

Engineering Contradiction:

Improveswitch activationVSAvoidaccidental activation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The pressing member is positioned in a preliminary state where it is ready to activate the switch but requires a deliberate pressing action to complete the connection. This preliminary positioning ensures the switch cannot be activated accidentally while remaining easy to operate when intentionally pressed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The push rod acts as an intermediary that only transmits force when the pressing member is deliberately activated. This creates a mechanical barrier that prevents accidental activation while maintaining ease of operation through simple pressing motion, converting the activation requirement from direct switch contact to indirect force transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)
