Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaping devices face issues with oxidation of pre-vapor formulations due to oxygen exposure, leading to reduced shelf-life and degradation of components.
Innovation Solution
Incorporation of a material comprising polymers and ultraviolet (UV) activated oxygen sequestering agents, such as 1,2 polybutadiene or a three-phase blend, into portions of the vaping device to absorb oxygen and prevent oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the vaping device is stored for extended periods, then the shelf-life is extended, but oxidation of the pre-vapor formulation occurs leading to degradation
Solution Approach 1:
The patent extracts and removes oxygen from the storage environment by incorporating oxygen sequestering agents into the device components. These agents actively consume oxygen from the air, creating an oxygen-depleted atmosphere that prevents oxidation of the pre-vapor formulation during extended storage periods.
Solution Approach 2:
The patent creates an inert atmosphere within the vaping device by using oxygen sequestering agents that consume oxygen from the air. This transforms the storage environment from oxygen-rich (promoting oxidation) to oxygen-depleted (inert-like), thereby protecting the pre-vapor formulation from oxidative degradation during extended storage.
2Reliability
If oxygen sequestering agents are incorporated into device portions, then oxidation is prevented, but the device complexity increases
Solution Approach 1:
The patent applies composite materials by combining oxygen sequestering agents with polymers to create multi-functional device portions. These composite materials simultaneously provide structural support (from the polymer) and oxygen scavenging protection (from the oxygen sequestering agent), thereby preventing oxidation without requiring separate protective components.
Solution Approach 2:
The patent implements multi-functionality by designing device portions that serve dual purposes: the polymer provides mechanical structure and containment, while the incorporated oxygen sequestering agent provides oxidative protection. This integration allows a single component to fulfill both structural and protective functions, reducing overall device complexity.
