Aerosol Generating Device with Detachable Shells for Component Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices are difficult to disassemble, leading to environmental waste and inefficient recycling of components when the substrate, battery, or device is exhausted.
Innovation Solution
The device features a shell composed of detachable sub-shells that form a mounting cavity, allowing easy removal and replacement of the atomizer and battery, with hermetically isolated air intake and atomizing cavities to maintain airflow integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shell is made as a single integrated piece, then the structural strength and integrity are improved, but the ease of disassembly and recycling is worsened
Solution Approach 1:
The shell is divided into multiple detachable sub-shells that can be separated from each other. Each sub-shell maintains sufficient structural strength while the modular design enables easy disassembly for recycling and maintenance of internal components such as the atomizer and battery.
2Ease of manufacture
If the air intake passage is directly open to the mounting cavity, then the ease of manufacturing is improved, but the pressure drop during inhalation is worsened
Solution Approach 1:
An isolation shield is introduced as an intermediary component that hermetically isolates the air intake passage and atomizing cavity from the mounting cavity. This shield includes an airflow passage that provides a controlled path for air intake, reducing pressure drop while maintaining manufacturing feasibility.
3Reliability
If the components are tightly fixed in the mounting cavity, then the reliability of component positioning is improved, but the ease of maintenance and replacement is worsened
Solution Approach 1:
The connection between sub-shells and the mounting cavity is designed to be dynamically adjustable, allowing the components to be securely fixed during operation for reliable positioning, while enabling easy removal and replacement when maintenance or recycling is needed.
4Ease of operation
If the shell is designed to be easily disassembled, then the ease of recycling is improved, but the structural strength is worsened
Solution Approach 1:
The shell is segmented into multiple sub-shells connected by detachable connections. Each segment maintains adequate structural strength for protection during use, while the detachable nature enables easy disassembly for recycling and component recovery at end-of-life.

AI summary
Aerosol generating device comprises a shell (10), an atomizer (20) and a battery (30). The shell comprises a plurality of sub-shells (11). Edges of at least part of the sub-shells are detachably connected to each other to together define a mounting cavity (10a). At least a portion of the atomizer is arranged within the mounting cavity. The atomizer is provided with an air intake passage (10c) and an atomizing cavity (25a). Each of the air intake passage and the atomizing cavity is hermetically isolated from the mounting cavity. The battery is provided in the mounting cavity and is detachably and electrically connected to the atomizer. In a disconnection state of the edges of the sub-shells, the mounting cavity is open to an outside of the aerosol generating device to allow the atomizer and the battery to be removed from the mounting cavity.
