Solution Overview

Problem

Current vape devices are limited to a single flavor or require manual swapping of flavors, which is inconvenient for users.

Innovation Solution

A vape device with multiple cartridge receiver regions and a moveable member that allows selective airflow paths to different e-liquid cartridges, ensuring easy flavor selection without dismantling the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple e-liquid cartridges are provided in the device, then flavor variety is improved, but device complexity increases due to need for manual swapping mechanisms

Engineering Contradiction:
Improveflavor varietyVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into multiple cartridge receiver regions (first, second, third regions) that can independently hold different e-liquid cartridges. This segmentation allows flavor variety without requiring complex manual swapping mechanisms, as multiple cartridges can be loaded simultaneously into separate regions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The airflow channel serves multiple functions by being capable of connecting to different cartridge receiver regions through the moveable member. The single airflow channel can selectively direct airflow to any of the multiple cartridge regions, providing multi-functionality without increasing overall device complexity.

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

2Device complexity

If manual swapping of cartridges is required, then device structure is simplified, but ease of operation deteriorates due to inconvenient flavor switching

Engineering Contradiction:
Improvedevice structureVSAvoidease of operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

A moveable member (moveable wall) is introduced that can dynamically change position between different cartridge receiver regions. This dynamic element allows the user to easily switch between flavors by moving the wall to block or open specific airflow channels, greatly improving ease of operation while maintaining relatively simple device structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The moveable member acts as an intermediary between the user and the multiple cartridge regions. Instead of requiring direct manipulation of cartridges, the user simply moves the intermediate wall element to select desired flavors, making operation convenient while keeping the overall structure simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If separate airflow channels are provided for each cartridge region, then flavor isolation is improved, but device complexity increases

Engineering Contradiction:
Improveflavor isolationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Each cartridge receiver region is provided with a dedicated airflow channel that is spatially separated from other regions. This local quality approach ensures that flavor from each cartridge remains isolated in its own channel, preventing cross-contamination. The separation is achieved through the physical arrangement of channels and the blocking action of the moveable member rather than complex isolation mechanisms.

Inventive Principle:
Principle #3Local quality
