Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices are difficult to clean and pose challenges in safely inserting and removing aerosol precursors due to their design, which complicates maintenance and user access.
Innovation Solution
The aerosol generating device features a moveable carriage with an induction coil that allows for easy access to the heating element, enabling safe cleaning and user access through an access window, while the induction coil's electrical connection/disconnection mechanism ensures safe operation during cleaning and precursor handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the induction coil is fixed in position to ensure stable electromagnetic field generation, then the heating function is reliable, but the device becomes difficult to clean and maintain
Solution Approach 1:
The induction coil is made moveable relative to the susceptor through a carriage mechanism. The coil can be positioned close to the susceptor for effective heating, then moved away to expose the susceptor for cleaning. This dynamic positioning resolves the contradiction between maintaining stable heating (when coil is close) and enabling cleaning access (when coil is retracted).
2Object-affected harmful factors
If the carriage is designed to fully enclose the susceptor for safety, then user safety is improved, but access for cleaning and maintenance becomes difficult
Solution Approach 1:
The carriage is designed with movable walls that can transition between enclosed and open states. When the coil is in the heating position, the carriage provides enclosure for safety. When the coil is retracted, the carriage opens to expose the susceptor through an access window, enabling cleaning while maintaining safety during operation.
Solution Approach 2:
The carriage structure is segmented into movable sections that can be opened independently. The access window is positioned to allow cleaning access without compromising the overall enclosure when closed, enabling both safety and maintenance requirements to be met through structural segmentation.
3Productivity
If the induction coil remains electrically connected during carriage movement, then operational readiness is maintained, but safety risks arise during cleaning operations
Solution Approach 1:
The system automatically disconnects the induction coil from its electrical supply before the carriage reaches the open/cleaning position. This preliminary disconnection action ensures that the susceptor is electrically inactive before user access is required, eliminating safety risks while maintaining operational readiness through automatic reconnection when the carriage returns to the closed position.
