Solution Overview

Problem

Aerosol generating devices face challenges in maintaining aesthetics while allowing easy separation of components, as existing designs often expose separation guide holes externally, compromising both appearance and disassemblability.

Innovation Solution

Incorporating a separation guide hole that is not externally visible, connected to an accommodation hole in a direction different from the accommodation hole, allowing for easy separation of the separation member without damaging the device's appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separation guide hole is provided on the external surface for separating the separation member from the main body, then the ease of separation is improved, but the appearance aesthetics deteriorates

Engineering Contradiction:

Improveease of separationVSAvoidappearance aesthetics

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The separation guide hole is extracted from the external surface and relocated to the internal structure. The hole is positioned inside the accommodation hole rather than on the outer surface, removing the visual defect while preserving the separation function through internal access.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The separation guide hole is repositioned from a two-dimensional external surface feature to a three-dimensional internal location within the accommodation hole. This spatial relocation allows the hole to be hidden from external view while remaining accessible for the separation operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Shape

If the separation guide hole is hidden internally, then the appearance aesthetics is improved, but the ease of operation for separation deteriorates

Engineering Contradiction:

Improveappearance aestheticsVSAvoidease of separation

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The accommodation hole serves as an intermediary structure that provides access to the separation guide hole. By introducing this intermediate space, the patent enables the separation operation to access the hidden hole through the accommodation cavity without requiring external visibility of the guide hole itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of repair

If components are made detachable for maintenance and repair, then the ease of repair is improved, but the device complexity increases

Engineering Contradiction:

Improvemaintenance convenienceVSAvoidstructural complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The separation guide hole is merged with the accommodation hole structure, utilizing the existing accommodation cavity to provide access to the separation mechanism. This integration reduces the need for separate access features and minimizes additional structural elements required for detachability.

Inventive Principle:

Principle #5Merging (Combining)
