Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nicotine-polymer complexes in oral products contain a significant number of acidic protons, necessitating high amounts of basic components to achieve desired pH, which can affect shelf life and stability.
Innovation Solution
Development of a modified nicotine-polymer complex with reduced acidic protons through proton-displacement, allowing for a lower amount of basic components to be used, thereby enhancing product stability and shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nicotine-polymer complexes are used in oral products, then nicotine delivery function is achieved, but high amounts of basic components are required to neutralize acidic protons which reduces shelf life and stability
Solution Approach 1:
The patent modifies the nicotine-polymer complex by changing the chemical state of acidic protons through proton-displacement, converting them to a less acidic form. This parameter change in the chemical properties of the complex reduces the need for basic components while maintaining nicotine delivery functionality, directly resolving the contradiction between reliability and quantity of substance
Solution Approach 2:
The patent converts the harmful acidic protons in the nicotine-polymer complex into a beneficial or neutral state through proton-displacement modification. By treating the acidic protons as a problem to be transformed rather than simply neutralized, the invention reduces the need for basic components and improves product stability, turning a detrimental feature into an advantage
2Stability of the object's composition
If high amounts of basic components are added to neutralize acidic protons, then desired pH is achieved, but product shelf life and stability deteriorate
Solution Approach 1:
The patent changes the chemical parameter of acidic protons in the nicotine-polymer complex through proton-displacement modification, reducing their acidity. This parameter change allows the product to maintain desired pH stability without requiring high amounts of basic components, thereby extending shelf life while preserving composition stability
Solution Approach 2:
The patent applies preliminary modification to the nicotine-polymer complex during manufacturing by displacing protons before the product is finalized. This preliminary action reduces the acidic proton content in advance, preventing future stability issues and extending shelf life without requiring excessive basic components during storage
