Solution Overview

Problem

Existing electronic vapor provision systems, such as e-cigarettes, struggle to accurately identify and safely operate with different cartomizer models due to variations in liquid flavors, nicotine strengths, and operational parameters, which can lead to incompatible or counterfeit components.

Innovation Solution

The system incorporates a control unit with a switching arrangement that selectively provides power to a first electrical circuit containing a characteristic-carrying element, such as a resistor or readable memory, to determine the cartomizer's identity, and a second circuit for vapor generation, ensuring appropriate power levels and operation based on the cartomizer's characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a control unit is designed to work with multiple cartomizer models, then the adaptability of the system is improved, but the reliability decreases due to incompatible or counterfeit components

Engineering Contradiction:
Improvecompatibility with different cartomizer modelsVSAvoidsystem safety and proper operation
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary identification of the cartomizer model before operation by measuring electrical characteristics (resistance, capacitance, or voltage) of the cartomizer's identification circuit. This preliminary action allows the control unit to verify compatibility and retrieve appropriate operational parameters stored in memory, ensuring reliable and safe operation from the start without risking incompatibility issues during actual vapor generation.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If the control unit identifies cartomizer characteristics by providing power to a first electrical circuit, then the measurement precision is improved, but the use of energy increases

Engineering Contradiction:
Improveaccuracy of cartomizer identificationVSAvoidpower consumption during identification
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by providing power only to the identification circuit (first electrical circuit) during the identification phase, rather than powering the entire cartomizer system. This selective power provision to a specific subset of components enables accurate measurement of electrical characteristics for model identification while minimizing overall energy consumption. The full power is only supplied to the vapor generation circuit after successful identification.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If the system stores operational parameters for different cartomizer models in memory, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveability to support multiple cartomizer modelsVSAvoidcontrol unit structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit incorporates a universal memory structure that stores operational parameters for multiple cartomizer models in a standardized format. This universal memory design allows the same hardware component to serve multiple functions: storing identification data, retrieving operational parameters, and providing lookup tables for different cartomizer configurations. This multi-functionality reduces overall device complexity compared to having separate dedicated storage for each cartomizer model.

Inventive Principle:
Principle #6Universality (Multi-functionality)
