Solution Overview

Problem

The high use cost of heat-not-burn cartridges is due to the entire cartridge being discarded after use, leading to inefficient and costly replacements.

Innovation Solution

An atomization device with a detachable structure comprising a first housing with a mouthpiece and a heating body, and a second housing that allows for plug-in and pull-out replacement of an atomizing matrix, eliminating the need for a hollow cooling segment and reducing the cartridge to only a tobacco segment, thereby lowering costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the entire heat-not-burn cartridge is discarded after use, then the device structure is simple and easy to manufacture, but the use cost becomes high

Engineering Contradiction:
Improvedevice structure simplicityVSAvoiduse cost
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The cartridge is divided into three main segments: a reusable main body (housing, battery, control circuit) and replaceable cartridges (containing heating element and tobacco rod). This segmentation allows the expensive reusable parts to be retained while only the consumable tobacco-containing parts are discarded, significantly reducing per-use cost compared to discarding the entire cartridge.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables recovery and reuse of valuable components (housing, battery, control electronics) while discarding only the consumable tobacco rod. The detachable cartridge mechanism facilitates easy separation and recovery of reusable parts, transforming a disposable design into a partially reusable system.

Inventive Principle:
Principle #34Discarding and recovering

2Object-affected harmful factors

If the hollow cooling segment is added to block heat transfer, then the mouthpiece is protected from overheating, but the device complexity increases

Engineering Contradiction:
Improvemouthpiece overheating protectionVSAvoiddevice structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A cooling segment is introduced as an intermediary component between the heating element and the mouthpiece. This cooling segment acts as a thermal buffer that blocks harmful heat transfer to the mouthpiece while allowing the device to maintain a simpler overall structure without requiring complex active cooling systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the mouthpiece is integrated into the first housing, then the hollow cooling segment can be omitted, but the heat transfer to the mouthpiece increases

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidmouthpiece temperature
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

Even when the mouthpiece is integrated into the first housing, a cooling segment is retained as a necessary intermediary to prevent direct heat transfer from the heating element to the mouthpiece. This maintains structural simplicity while protecting the mouthpiece from overheating.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If the atomizing matrix is detachably plugged into the heating body, then the replacement efficiency is improved, but the connection reliability may be affected

Engineering Contradiction:
Improveatomizing matrix replacement efficiencyVSAvoidconnection reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The atomizing matrix is designed as a detachable segment that can be easily plugged into and removed from the heating body. This segmentation enables quick replacement of the consumable atomizing matrix without requiring disassembly of the entire device, improving replacement efficiency while maintaining connection reliability through proper mechanical engagement features.

Inventive Principle:
Principle #1Segmentation
