Aerosol Dusting Composition With Denatonium for Abuse Deterrence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquefied-gas aerosol dusters face challenges in preventing inhalation abuse incidents, as existing denaturants either interfere with normal use or are ineffective at discouraging misuse when their concentration is too low.
Innovation Solution
A liquefied-gas aerosol dusting composition containing denatonium benzoate at a concentration ranging from 5 ppm to 50 ppm, which is undetectable during normal use but detectable in abuse scenarios, ensuring it does not interfere with the product's intended function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the concentration of denatonium benzoate in the liquefied-gas aerosol dusting composition is increased to improve deterrence against inhalation abuse, then the effectiveness as a deterrent increases, but the denatonium benzoate interferes with normal product use
Solution Approach 1:
The patent applies parameter changes by precisely controlling the concentration of denatonium benzoate within the range of 5-50 ppm. This optimization resolves the contradiction by finding the specific concentration parameter that provides sufficient deterrent effect while maintaining normal product usability, preventing both under-deterrence and over-interference.
Solution Approach 2:
The patent employs partial action by using a low concentration of denatonium benzoate (5-50 ppm) that is sufficient for deterrence purposes without exceeding the threshold that would interfere with normal product use. This partial application of the bittering agent achieves the desired protective effect while minimizing negative impacts on usability.
2Ease of operation
If the concentration of denatonium benzoate is decreased to improve normal product use, then product usability is maintained, but the denatonium benzoate becomes ineffective as a deterrent to accidental or intentional misuse
Solution Approach 1:
The patent resolves this contradiction by establishing the minimum effective concentration parameter of 5-50 ppm for denatonium benzoate. This parameter range ensures that the concentration is high enough to provide deterrent effect while low enough to maintain normal product usability, preventing both ineffectiveness and over-interference.
3Reliability
If a bittering agent is added to discourage inhalation abuse, then deterrence is improved, but the bittering agent may interfere with normal product use
Solution Approach 1:
The patent applies parameter changes by optimizing the concentration of denatonium benzoate to 5-50 ppm, which is sufficient to deter inhalation abuse but low enough to avoid interfering with normal product use. This precise parameter control resolves the contradiction between deterrence effectiveness and normal usability.
Solution Approach 2:
The patent uses partial action by incorporating a small amount of denatonium benzoate (5-50 ppm) that provides adequate deterrent effect without exceeding the level that would cause interference with normal product use, thus resolving the contradiction between protection and usability.
