Desktop Cartridge Refilling Control for Aerosol Device Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol provision systems, such as e-cigarettes, face issues with the limited lifespan of consumable cartridges due to exhausted aerosol-generating material, leading to degradation and reliability concerns, as they are often not reusable and require frequent replacement.
Innovation Solution
A desktop refilling device that facilitates the transfer of aerosol-generating material from a reservoir to a reusable cartridge, allowing users to refill and reuse the cartridge, extending its lifespan by decoupling the refilling process from the aerosol provision device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the article is refilled continuously to extend its life, then the duration of use is improved, but the reliability deteriorates due to component degradation
Solution Approach 1:
The patent applies the disposable principle by making the article (cartridge) a single-use component that is discarded after its aerosol-generating material is exhausted. This resolves the contradiction by preventing continuous refilling that would degrade components, while still achieving extended system use through replacement of the inexpensive disposable article rather than the expensive provision device. The article is designed to be replaced rather than refilled, maintaining reliability while extending overall system duration.
2Reliability
If the article is made non-refillable to maintain reliability, then the reliability is improved, but the duration of action deteriorates as the article must be replaced after exhaustion
Solution Approach 1:
The patent applies the discarding and recovering principle by discarding the exhausted article (cartridge) and recovering/reusing the expensive aerosol provision device. This resolves the contradiction by maintaining reliability through preventing component degradation from refilling, while extending duration of use through systematic replacement of disposable articles. The system recovers value by reusing the durable provision device multiple times with different disposable articles.
3Duration of action of moving object
If manual refilling is performed to extend article life, then the duration of use is improved, but the ease of operation deteriorates due to complex refilling procedures
Solution Approach 1:
The patent resolves this contradiction by eliminating manual refilling operations entirely. The disposable article is designed to be replaced as a complete unit rather than refilled manually. This maintains ease of operation by simplifying the user action to simple replacement, while extending duration of use through the ability to replace articles multiple times. The complex refilling procedure is replaced by a simple swap operation.
4Reliability
If the article is designed for replacement rather than refilling, then the reliability is improved, but the loss of substance deteriorates as unused material is wasted
Solution Approach 1:
The patent applies discarding and recovering by discarding the entire article including any remaining unused aerosol-generating material. This resolves the contradiction by prioritizing reliability through preventing component degradation, accepting the loss of unused material in the disposable article. The system recovers value by reusing the expensive provision device, making the loss of substance in the inexpensive article acceptable from an economic and reliability perspective.
