Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning of the aerosol generating device is performed, then cleaning flexibility is maintained, but cleaning effectiveness deteriorates due to resin buildup in hard-to-reach areas

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidcleaning accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cleaning system performs cleaning actions automatically without requiring manual disassembly or direct access to internal components. The cleaning head with bristles automatically cleans the heating element and airflow channels through rotational motion, enabling the system to clean itself without human intervention in hard-to-reach areas.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical cleaning actions are replaced by an automated cleaning mechanism. The cleaning head with bristles and rotational motion substitutes for manual disassembly and cleaning operations, providing consistent cleaning effectiveness while maintaining ease of operation through automated execution.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the aerosol generating device is disassembled for cleaning, then cleaning accessibility improves, but device complexity increases due to multiple parts to manage

Engineering Contradiction:

Improvecleaning accessibilityVSAvoidnumber of parts

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning system is segmented into modular components including a cleaning head with bristles, a cleaning rod, and integration with the aerosol generating device's existing structure. This segmentation allows the cleaning function to be added as a separate module without requiring disassembly of the main device, maintaining accessibility while managing complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cleaning head and rod assembly serves multiple functions: cleaning the heating element, clearing airflow channels, and maintaining seal integrity. This multi-functionality consolidates multiple cleaning operations into a single integrated mechanism, improving accessibility without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If cleaning solution is applied directly to the heating element, then cleaning effectiveness improves, but risk of damage increases due to heat-sensitive materials

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidheat sensitivity damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cleaning rod is pre-saturated with cleaning solution before being inserted into the aerosol generating device. This preliminary action ensures that cleaning solution is delivered controllably to the heating element without overwhelming it, maintaining cleaning effectiveness while minimizing thermal damage risk through controlled application.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cleaning rod acts as an intermediary between the cleaning solution reservoir and the heating element. It delivers cleaning solution directly to the heating element in a controlled manner, preventing direct contact between large volumes of cleaning solution and the heat-sensitive material, thus reducing damage risk while maintaining cleaning effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)
