Solution Overview

Problem

Existing electronic cigarettes have complex internal structures that lead to inefficient battery utilization and risk of nicotine solution spillage when refilling, due to separate wire connections and insecure cartridge separation mechanisms.

Innovation Solution

An electronic cigarette design utilizing a power supply system with a center pin and contact pin that connect via a pop-up pin structure with an elastic body, allowing for stable power connection and disconnection without wires, and a connector mechanism that releases before the cartridge is fully separated, preventing solution spillage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wires are used to connect internal elements for power supply, then power transmission is reliable, but the internal structure becomes complicated and battery utilization efficiency decreases

Engineering Contradiction:
Improvepower transmission reliabilityVSAvoidinternal structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the wire connections from the internal structure. Instead of using wires to connect the power supply portion and smoke generating portion, it employs direct contact through contact pins (first and second contact pins) that make electrical contact when the cartridge is inserted. This removes the unnecessary wire components, simplifying the internal structure while maintaining reliable power transmission through the contact pins.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The contact pins serve multiple functions: they provide electrical connection for power supply, act as mechanical engagement elements for the cartridge, and enable the power on/off control through their contact/separation mechanism. This multi-functionality reduces the need for separate components, further simplifying the overall structure.

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

2Ease of operation

If a separate switch is used to control power on and off, then power control is precise, but the internal structure becomes more complex and battery utilization efficiency decreases

Engineering Contradiction:
Improvepower control precisionVSAvoidinternal structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the separate switch component entirely. Instead of using a switch to control power, it relies on the mechanical insertion and removal of the cartridge itself to make or break the electrical contact through the contact pins. This eliminates the need for a separate switch, simplifying the internal structure while maintaining precise power control based on cartridge presence.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cartridge insertion and removal actions perform the power on/off function automatically. When the user inserts the cartridge, the contact pins make contact and power is supplied; when the cartridge is removed, contact is broken and power stops. This self-service mechanism eliminates the need for separate control components.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the cartridge can be easily separated for refilling, then ease of operation is improved, but nicotine solution spillage may occur during separation

Engineering Contradiction:
Improvecartridge separation easeVSAvoidnicotine solution spillage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements a preliminary action sequence where the power supply connection is broken before the cartridge is fully separated. The elevating portion rises to disconnect the power contact pins first, and only after this disconnection does the cartridge become fully separable. This preliminary power disconnection prevents solution spillage by ensuring the sealing connection is maintained until power is safely disconnected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces dynamic movement through the elevating portion that can change position between lowered (connected) and raised (disconnected) states. This dynamic mechanism allows the system to transition smoothly from a connected state to a disconnected state, controlling the sequence of separation to prevent spillage while maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics
