Flavor Generator Temperature Estimation Without Extra Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flavor generation devices face challenges in determining the temperature of internal electronic components without increasing weight, size, and cost, as they often rely on ambient temperature sensors which are not directly indicative of the components' temperatures.
Innovation Solution
A flavor generation device design that includes a temperature sensor adjacent to a first electronic component, allowing the controller to estimate the temperature of a second electronic component, such as a power supply, without a dedicated sensor for the power supply, thereby reducing the need for additional components and simplifying the device structure.

Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is installed adjacent to each electronic component to accurately measure their temperatures, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The temperature sensor disposed in or adjacent to the first electronic component serves multiple functions: it measures both the temperature of the first electronic component and estimates the temperature of the second electronic component (power supply). This multi-functionality eliminates the need for a separate temperature sensor for the power supply, reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The controller acts as an intermediary that estimates the temperature of the second electronic component based on the temperature reading from the first electronic component. This estimation mechanism allows indirect temperature measurement without requiring direct contact with the power supply, resolving the contradiction between measurement accuracy and device complexity.
2Device complexity
If ambient temperature sensors are used to monitor device temperature, then device complexity is reduced, but measurement precision deteriorates as ambient temperature does not reflect internal component temperatures
Solution Approach 1:
The temperature sensor is strategically disposed in or adjacent to the first electronic component (controller) rather than measuring ambient temperature. This localized measurement approach ensures that the temperature reading reflects the actual conditions of the internal electronic components, improving measurement precision while the estimation algorithm extends this local measurement to monitor the second component as well.

AI summary
A flavor generation device comprising: a case; a first electronic component disposed in the case; a temperature sensor disposed in or in the vicinity of the first electronic component; a second electronic component disposed in the case; and a control device. The second electronic component is disposed away from the temperature sensor at a distance greater than a distance between the temperature sensor and the first electronic component. The control device is configured to detect or estimate the temperature of the second electronic component on the basis of an output value from the temperature sensor.
