Concealed Fastening Structure for Tamper-Resistant Aerosol Generators

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aerosol generation devices with exposed fastening structures are prone to damage and user-induced disassembly, leading to operational failures and difficulty in determining if the device has been tampered with.

Innovation Solution

The aerosol generation device incorporates a concealed fastening structure, where the second housing, battery, and fastening portion are accommodated within a case, preventing external exposure and user access through a combination of grooves, hooks, and adhesive coverings that leave irreversible marks upon separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the fastening structure is exposed on the outer portion of the aerosol generation device, then the device is easier to assemble and disassemble, but the fastening structure becomes vulnerable to external damage and user-induced disassembly

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoiddurability of fastening structure

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The fastening structure is extracted from the outer portion of the device and relocated to the inner space, where it is no longer exposed to external damage while maintaining its functional integrity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The fastening structure is nested within the inner space of the device, concealed by the outer housing, which protects it from external forces while allowing the device to be assembled and disassembled through the designated opening

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the fastening structure is concealed within the device, then the durability is improved by preventing external damage, but it becomes difficult to discern whether the device has been arbitrarily disassembled

Engineering Contradiction:

Improvedurability of fastening structureVSAvoiddetectability of arbitrary disassembly

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The adhesive portion includes a marking region with a color different from the rest of the adhesive portion, which becomes visible when the cover is separated from the outer housing, indicating arbitrary disassembly

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The adhesive portion has different properties in different regions: the marking region has a distinct color for detectability, while the rest of the adhesive portion provides strong bonding to prevent disassembly

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If a simple concealed fastening structure is used, then the manufacturing complexity is reduced, but the structure can still be easily disassembled by users

Engineering Contradiction:

Improvesimplicity of fastening structureVSAvoidresistance to arbitrary disassembly

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

An adhesive portion is introduced as an intermediary between the cover and the outer housing, providing strong bonding that prevents arbitrary disassembly while maintaining a simple overall structure

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The adhesive portion is pre-applied to the outer housing before assembling the cover, creating a permanent bond that prevents future disassembly without requiring complex fastening mechanisms

Inventive Principle:

Principle #10Preliminary action
