Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices suffer from debris accumulation during use, which can impair operation and reduce the operational life of components like the heater and power source.
Innovation Solution
Incorporation of a debris collector that moves between a first position to collect debris and a second position to release it, allowing easy removal, along with features like a controller for automatic locking and unlocking based on user input or temperature, ensuring reliable debris collection and extended device life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heater is used to heat the aerosol generating substrate, then aerosol generation is achieved, but debris is generated and accumulates in the heating chamber
Solution Approach 1:
The patent extracts the harmful debris from the heating chamber by providing a debris collector that accumulates debris in a separate location. The collector is movable between a first position where it collects debris generated during heating and a second position where it permits debris removal, thereby separating the harmful byproduct from the functional heating space.
Solution Approach 2:
The debris collector acts as an intermediary component between the heating chamber and the external environment. It intercepts debris generated during heating operations and temporarily holds it in a controlled manner, preventing direct accumulation in the heating chamber while enabling convenient periodic removal.
2Device complexity
If debris is allowed to accumulate in the heating chamber, then the device structure remains simple, but operation is impaired and component lifespan is reduced
Solution Approach 1:
The debris collector is designed to be movable between two positions by the user without requiring complex mechanisms or tools. The user can simply move the collector from the first position to the second position to remove debris, enabling self-service maintenance that extends operational life while adding minimal complexity to the device structure.
3Ease of operation
If the debris collector is designed to be easily movable, then debris removal is simplified, but collection reliability may be compromised
Solution Approach 1:
The debris collector is designed with dynamic positioning capability, being movable between a first position for reliable collection during heating operations and a second position for easy debris removal. This dynamic design allows the same component to fulfill both reliability and ease of operation requirements at different operational stages.
Solution Approach 2:
The device is segmented into functional zones: the heating chamber where aerosol generation occurs and the debris collector where debris is accumulated. This segmentation allows the debris collector to be optimized for both reliable collection (when positioned to intercept debris) and easy removal (when positioned for access), without compromising either function.

AI summary
An aerosol generating device includes a heating chamber for receiving an aerosol generating substrate, a heater for heating an aerosol generating substrate positioned in the heating chamber, and a debris collector. The debris collector is movable between a first position in which the debris collector is configured to collect debris generated inside the heating chamber during heating of an aerosol generating substrate by the heater and a second position in which the debris collector is configured to permit the removal or release of collected debris.
