Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple aerosol generators are used to provide customized aerosol experiences, then user experience customization is improved, but device complexity increases

Engineering Contradiction:

Improveaerosol generation customizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single power generator is designed to serve multiple aerosol generators through frequency multiplexing. The power generator can output signals at different frequencies to selectively activate different aerosol generators, allowing one device to perform multiple selection functions that would otherwise require separate control mechanisms for each generator.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Frequency filter arrangements act as intermediary components between the power generator and aerosol generators. These filters selectively pass specific frequency signals to designated aerosol generators while blocking other frequencies, enabling indirect control without requiring direct switching mechanisms or complex control circuits at each generator.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If traditional switching mechanisms are used to select aerosol generators, then selective activation is achieved, but reliability decreases due to moving parts

Engineering Contradiction:

Improveselective activation capabilityVSAvoidmechanism reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical switching mechanisms with an electrical frequency-based control system. Instead of using physical switches or relays with moving parts, the system uses a power generator that outputs signals at different frequencies, combined with frequency filter arrangements, to selectively activate aerosol generators. This eliminates mechanical wear and failure modes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses periodic alternating current signals at different frequencies to control aerosol generator activation. By varying the frequency of the periodic power signal, the system can selectively activate different aerosol generators associated with specific frequency ranges, providing reliable electronic control without mechanical components.

Inventive Principle:

Principle #19Periodic action

3Device complexity

If frequency filter arrangements are used to selectively activate aerosol generators, then mechanism complexity is reduced, but power signal transmission control difficulty increases

Engineering Contradiction:

Improveselection mechanism complexityVSAvoidfrequency-based control complexity

Core Design Contradiction:

Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The system controls power transmission by changing the frequency parameter of the electrical signal rather than using complex mechanical or electronic switching networks. The power generator varies its output frequency to select which aerosol generator is activated, and frequency filter arrangements are designed with specific cutoff frequencies to respond predictably to these parameter changes, simplifying the overall control architecture.

Inventive Principle:

Principle #35Parameter changes
