Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-vaping devices face issues with separate formulations reacting within the reservoir, leading to degradation and reduced shelf-life, which affects the sensory experience due to the formation of reaction products.
Innovation Solution
A base with a power supply, connectors, and control circuitry that independently control dispersion generation in separate cartridges, allowing for distinct electrical power management and communication to prevent formulation reactions, featuring a cartridge holder with restricted slots to ensure separate dispersion generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple formulations are held in a single reservoir to provide multiple sensory experiences, then the device can offer diverse vaping experiences, but the formulations react with each other causing degradation and reducing shelf-life
Solution Approach 1:
The patent divides the reservoir into multiple separate cartridges, each containing a different formulation. This segmentation prevents direct contact and chemical reactions between formulations while allowing the device to offer multiple sensory experiences by selecting from different cartridges. Each cartridge is sealed independently to maintain formulation stability.
2Reliability
If separate formulations are stored in separate cartridges with independent control, then formulation reactions are prevented and shelf-life is extended, but the device complexity increases due to multiple connectors and control circuitry
Solution Approach 1:
The base unit is designed with universal connectors and control circuitry that can interface with multiple different cartridge types. The control system can selectively activate different cartridges based on user input, providing multi-functionality without requiring separate dedicated systems for each formulation. This reduces overall complexity compared to having completely separate control systems for each cartridge.
3Productivity
If electrical power is supplied to multiple cartridges simultaneously, then dispersion generation is efficient, but formulation reactions may occur due to heat transfer between cartridges
Solution Approach 1:
The control circuitry is configured to activate cartridges in alternating or sequential periods rather than simultaneously. When one cartridge is activated for dispersion generation, other cartridges remain inactive. This periodic activation pattern prevents heat transfer between cartridges that could cause formulation reactions, while maintaining overall productivity by quickly switching between cartridges to deliver multiple dispersions.
