Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current malodour counteracting technologies (MOC) are inefficient at lower concentrations and struggle to effectively reduce the perception of fecal malodours, which is essential for promoting public acceptance and use of toilets and discouraging open defecation.
Innovation Solution
A composition comprising a malodour antagonist system formed of ingredients that block specific receptors of fecal malodours, combined with a functional perfume accord having malodour counteraction properties, is used to decrease, limit, or eliminate the perception of fecal malodour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional malodour counteracting compositions are used, then malodour perception is reduced to some extent, but excessive amounts are required due to low detection thresholds of malodourant compounds
Solution Approach 1:
The patent introduces a malodour antagonist system as an intermediary substance that blocks the detection of malodourant compounds by interfering with their interaction with olfactory receptors. This mediator approach allows for effective malodour counteraction at lower concentrations by preventing the malodourants from binding to receptors, rather than relying on high amounts of masking agents.
Solution Approach 2:
The patent changes the mechanism of action from physical masking to biochemical blocking by introducing compounds that specifically target and block malodourant-receptor interactions. This parameter change in the counteracting mechanism enables significantly reduced concentrations to achieve the same effectiveness, as the blocking action occurs at the molecular interaction level rather than requiring high volumes of composition.
2Reliability
If higher concentrations of MOC composition are used to overcome low detection thresholds, then malodour perception is better controlled, but the efficiency and cost-effectiveness decrease
Solution Approach 1:
The malodour antagonist system acts as a highly efficient intermediary that blocks malodourant detection at the receptor level, providing superior efficiency compared to conventional masking approaches. This intermediary mechanism achieves better malodour control with lower concentrations, directly improving productivity and cost-effectiveness.
Solution Approach 2:
The patent employs a composite approach by combining a malodour antagonist system with a functional perfume accord. This composite composition leverages the blocking capability of the antagonist alongside the masking and perceptual modulation properties of the perfume ingredients, creating a synergistic effect that enhances overall efficiency and malodour control.
3Object-affected harmful factors
If traditional masking agents are used to suppress malodours, then the perception is masked, but the complex mixture of malodourant compounds requires excessive amounts of counteracting substances
Solution Approach 1:
The malodour antagonist system serves as a targeted intermediary that specifically blocks the detection of malodourant compounds in the complex mixture. By interfering with the binding between individual malodourant molecules and their receptors, this mediator approach effectively handles complex mixtures without requiring excessive amounts of counteracting substances, as the blocking action is molecular-level specific.
Solution Approach 2:
The patent changes the counteracting parameter from concentration-based masking to mechanism-based blocking. By introducing compounds that alter the biochemical interaction parameter between malodourants and receptors, the system achieves effective malodour suppression with reduced substance quantities, as the blocking mechanism is inherently more efficient than physical masking.
