Electronic Aerosol Provision With Extended Heating for Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems face challenges in managing the disposal of consumable parts containing trace amounts of constituents, which can be inconvenient and potentially harmful to the environment if not disposed of properly.
Innovation Solution
A method and device for aerosol generating systems that perform multiple aerosolization processes to reduce the concentration of a first constituent, such as nicotine, in the aerosol generating material to below 0.05 mg/ml, using controlled heating and monitoring, and provide alerts or block the air outlet until the material is substantially free of the constituent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single aerosolization process is performed on consumable material, then the device delivers aerosol to the user efficiently, but trace amounts of harmful constituents remain in the material requiring specialist disposal
Solution Approach 1:
The system performs a preliminary extended heating process on the consumable material after normal aerosol generation to decompose and eliminate trace harmful constituents before the user finishes using the consumable. This preliminary action ensures that by the time the consumable is discarded, harmful substances have been reduced to safe levels, resolving the contradiction between efficient aerosol delivery and harmful residue elimination.
Solution Approach 2:
The system changes the heating parameters (temperature, duration) from normal aerosol generation settings to extended decomposition settings. By adjusting these parameters, the same heating element can efficiently generate aerosol during normal use and then thoroughly decompose residual harmful substances in a post-use phase, addressing both productivity and harmful factor reduction.
2Ease of operation
If the consumable part is disposed of after normal use, then the user can continue using the device, but harmful constituents may damage the environment
Solution Approach 1:
The device automatically performs the extended heating process to eliminate harmful constituents without requiring user intervention. The system self-monitors the consumption level and autonomously activates the decomposition phase, allowing users to simply discard the consumable in regular trash after use, thus achieving both ease of operation and environmental safety.
Solution Approach 2:
The system converts the potentially harmful trace constituents into beneficial outcomes by thermally decomposing them into harmless substances. The extended heating process transforms the harmful chemical residues into safe byproducts, allowing convenient disposal while protecting the environment, effectively turning a harmful situation into a beneficial one.
3Object-affected harmful factors
If extended heating is applied to eliminate constituents, then environmental safety is improved, but energy consumption and device complexity increase
Solution Approach 1:
The system employs periodic action by alternating between normal aerosol generation mode and extended decomposition mode. The heating element operates at high power only during brief extended phases when the consumable is depleted, rather than continuously. This periodic operation eliminates harmful constituents while minimizing overall energy consumption, as the extended heating occurs only momentarily at the end of consumable life.
Solution Approach 2:
The system applies partial excessive action by performing extended heating that goes beyond what is needed for normal aerosol generation. This excessive heating is applied only to the residual material in the consumable cartridge, not the entire device, and only for the duration necessary to eliminate constituents. The action is targeted and limited, achieving harmful factor reduction without excessive overall energy waste.
