Solution Overview

Problem

Existing aerosol-generating devices rely on frequent interactions with external servers for validation and authentication, leading to a burdensome user experience and excessive network resource consumption.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frequent connections to external servers are implemented for validation and authentication, then authorized operator verification reliability is improved, but operator interaction burden and network resource consumption increase

Engineering Contradiction:

Improveauthorized operator verification reliabilityVSAvoidoperator interaction burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs authentication and validation actions in advance by establishing trusted relationships between devices before actual use. Behavior metrics are collected and analyzed preliminarily to determine authorized operator status, so that when aerosol-generation is needed, the verification is already complete and no frequent interactions are required.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The aerosol-generating device autonomously determines whether the current operator is authorized by analyzing behavior metrics locally stored in its memory. The device serves itself by making authentication decisions without requiring frequent external server connections, thereby reducing operator burden while maintaining verification reliability.

Inventive Principle:

Principle #25Self-service

2Reliability

If frequent connections to external servers are implemented for validation and authentication, then authorized operator verification reliability is improved, but network resource consumption increases

Engineering Contradiction:

Improveauthorized operator verification reliabilityVSAvoidnetwork resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

Authentication and validation are performed in advance by establishing trusted relationships and collecting behavior metrics before actual aerosol-generation operations. This preliminary action ensures verification reliability is established upfront, eliminating the need for frequent network connections and reducing ongoing network resource consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device autonomously performs verification by analyzing locally stored behavior metrics and determining authorized operator status without requiring frequent external server connections. This self-service approach maintains verification reliability while dramatically reducing network resource consumption and energy loss.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If behavior metrics are collected and analyzed locally to determine authorized operator status, then operator interaction burden and network resource consumption are reduced, but device complexity increases

Engineering Contradiction:

Improveoperator interaction burdenVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the authentication and verification functions from external servers and implements them locally within the aerosol-generating device. By taking out the complex verification logic and placing it in the device's processing circuitry and memory, the system reduces operator interaction burden and network dependency while the added complexity is confined to the device itself rather than the overall system architecture.

Inventive Principle:

Principle #2Taking out (Extraction)
