E-vaping Mouth-end Insert for Flavor Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-vaping devices face challenges in adding flavorants without adverse reactions with other ingredients in the pre-vapor formulation, leading to degradation and loss of flavor, especially when mixing multiple flavorants.
Innovation Solution
Incorporating flavorants, taste compounds, and aromas into a solid matrix within the mouth-end insert or add-on tip of e-vaping devices using thermoplastic polymers like polypropylene or polyethylene, ensuring they are homogeneously distributed and resistant to heat, allowing for improved flavor delivery and sensory experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If flavorants are added to the pre-vapor formulation, then flavor delivery is improved, but adverse reactions and degradation occur
Solution Approach 1:
The patent separates the flavor delivery function from the pre-vapor formulation by placing flavorants in a distinct mouth-end insert component. This segmentation allows the formulation to remain stable while the insert provides flavor delivery independently, eliminating adverse reactions between flavorants and formulation ingredients.
Solution Approach 2:
The mouth-end insert acts as an intermediary component between the pre-vapor formulation and the user's mouth. It contains the flavorants in a separate matrix that interfaces with the vapor without direct mixing, mediating the flavor delivery while preventing chemical interactions with the formulation.
2Adaptability or versatility
If multiple flavorants are mixed together, then flavor variety is improved, but degradation and loss of flavor occur
Solution Approach 1:
Multiple flavorants are segmented into separate regions or compartments within the mouth-end insert matrix. This physical separation prevents harmful interactions between different flavorants while still allowing them to be delivered together, preserving flavor integrity and preventing degradation.
Solution Approach 2:
Different regions of the mouth-end insert matrix contain different flavorants with locally optimized properties. Each local region maintains the quality and stability of its specific flavorant while the overall insert provides diverse flavor delivery through its multi-component structure.
3Quantity of substance
If flavorants are added directly to the storage container, then flavor delivery is improved, but adverse reactions with ingredients occur
Solution Approach 1:
The mouth-end insert serves as an intermediary barrier between the pre-vapor formulation in the storage container and the user's mouth. It contains flavorants in a separate matrix that delivers flavor without direct contact or mixing with formulation ingredients, eliminating the pathway for adverse reactions.
Solution Approach 2:
The flavorants are extracted from the pre-vapor formulation system and placed into a separate mouth-end insert component. This extraction removes the source of adverse reactions while preserving the flavor delivery function, as the insert interfaces with vapor without requiring direct mixing with formulation ingredients.
