Solution Overview
Problem
Users are unable to determine if an aerosol generating device is usable and the quality of aerosols is inconsistent due to the inability to detect the remaining amount of aerosol generating material, which affects the heating process.
Innovation Solution
An aerosol generating device equipped with a sensor that measures the remaining amount of aerosol generating material by detecting the capacitance of the cartridge, allowing for accurate detection and adjustment of the heating process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is placed close to the cartridge to improve measurement accuracy, then the detection precision of remaining material amount improves, but the device structure becomes more complex
Solution Approach 1:
The sensor is nested within the housing structure, with the cover serving as both a protective element and a mounting platform for the sensor. The sensor is positioned within the space defined by the housing and cartridge arrangement, utilizing the existing structural layers to achieve close proximity measurement without adding external complexity.
Solution Approach 2:
The cover acts as an intermediary element between the sensor and the cartridge. It provides a mounting surface for the sensor while maintaining an optimized distance to the cartridge, enabling accurate measurement without direct contact. The cover mediates the spatial relationship between the measurement device and the measured object.
2Ease of operation
If the remaining amount of aerosol generating material is not detected, then the device structure remains simple, but the user convenience deteriorates and aerosol quality becomes non-uniform
Solution Approach 1:
The sensor provides feedback information about the remaining amount of aerosol generating material to the processor. This feedback mechanism enables the system to monitor material levels and adjust heating accordingly, improving user convenience and aerosol quality consistency through information-based control.
Solution Approach 2:
The device performs self-monitoring of its material supply status through the integrated sensor system. The processor automatically detects remaining material levels and adjusts heating parameters without user intervention, enabling the device to service itself and maintain optimal performance throughout its operational life.
