Solution Overview

Problem

Existing inhalation devices, such as electronic cigarettes, do not transmit heating profiles to control the heating operation of other devices, and the transmission of tar taste information is not triggered by the sender.

Innovation Solution

An inhalation device configured to transmit a heating profile to another inhalation device, which includes generating and transmitting a heating profile based on the device's and the other device's heater characteristics, and controlling the heating operation using a peer-to-peer connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If inhalation devices use peer-to-peer communication to exchange information, then device compatibility and user experience are improved, but the transmission of critical heating control information is incomplete without heating profile data

Engineering Contradiction:
Improvedevice compatibilityVSAvoidheating profile transmission
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The heating profile is transmitted in advance from the first inhalation device to the second inhalation device before the actual heating operation occurs. This preliminary transmission ensures that the receiving device has the necessary heating control data ready, enabling complete and accurate heating operations without information loss during the actual use phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The heating profile acts as an intermediary data structure that carries essential heating control information between the first inhalation device (sender) and the second inhalation device (receiver). This intermediary element enables the transfer of complex heating parameters including temperature profiles, power levels, and timing information that would otherwise be lost in direct device communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If inhalation devices transmit detailed heater characteristics and heating profiles, then heating operation control precision is improved, but device complexity and data transmission requirements increase

Engineering Contradiction:
Improveheating operation control precisionVSAvoiddata transmission requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The heating profile transforms complex heater characteristics into a simplified parameter set that includes temperature profiles, power levels, and timing information. This parameter transformation maintains the precision needed for accurate heating control while reducing the complexity of data that needs to be transmitted between devices. The profile uses standardized parameters that can be efficiently encoded and transmitted.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Instead of transmitting the entire heater characteristic data set, the invention creates a simplified copy or representation of the heating behavior through the heating profile. This copy contains only the essential parameters needed to reproduce the heating operation accurately, reducing transmission requirements while maintaining control precision.

Inventive Principle:
Principle #26Copying
