Halo Active Aromatic Sulfonamide Filter for Odor Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filters fail to effectively neutralize or destroy odor-causing molecules in fluid streams, requiring separate systems for odor control and filtration, which increases space and equipment requirements.
Innovation Solution
The use of filters with a porous substrate containing halo active aromatic sulfonamide compounds, such as those following Formula (I), which are integrated into the filter medium to neutralize and destroy odor-causing molecules, combining odor control with filtration functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate systems are used for filtration and odor control, then each function can be optimized independently, but the overall system complexity and space requirements increase
Solution Approach 1:
The patent combines filtration and odor control functions into a single integrated filter system. The filter medium incorporates odor-neutralizing agents that actively destroy odor-causing molecules while simultaneously filtering particles from the fluid stream, eliminating the need for separate odor control equipment and reducing overall system complexity
Solution Approach 2:
The filter is designed to perform multiple functions: physical filtration of particles and active chemical neutralization of odor molecules. The filter medium contains both filtering capabilities and embedded odor-controlling compositions, allowing one component to serve dual purposes and reducing the number of separate systems required
2Reliability
If separate systems are used for filtration and odor control, then each function can be optimized independently, but the space and equipment requirements increase
Solution Approach 1:
The patent merges odor control functionality directly into the filter medium, eliminating the need for separate odor control equipment. The odor-neutralizing agents are incorporated throughout the filter structure, allowing space savings while maintaining effective odor control through direct contact with odor-causing molecules in the fluid stream
3Object-affected harmful factors
If odor-causing molecules are masked using perfume, then the odor is concealed, but the underlying odorific molecules remain intact and can cause issues downstream
Solution Approach 1:
The patent converts the harmful odor-causing molecules into beneficial neutral compounds through chemical reaction. The odor-controlling compositions actively destroy odorific molecules by reacting with them, transforming the harmful substance into harmless products, rather than merely masking the odor with perfume as in conventional approaches
4Productivity
If existing filters are used without odor-controlling compositions, then the filtration function is maintained, but odor-causing molecules are not neutralized or destroyed
Solution Approach 1:
The patent utilizes the porous structure of the filter medium to incorporate odor-controlling compositions throughout the filtration path. The porous substrate provides surface area and volume for embedding the odor-neutralizing agents, ensuring that odor-causing molecules are exposed to and destroyed by the active compositions as the fluid stream passes through the filter
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The filters effectively reduce and eliminate odor-causing molecules over an extended period, reducing the need for additional odor control systems and minimizing space and equipment requirements, while maintaining filtration efficiency.

AI summary
A filter is treated with a reduced amount of a halo active aromatic sulfanomide compound of Formula (I):wherein R1, R2, R3, R4, and R5 are independently selected from hydrogen, COOR′, CON(R″)2, alkoxy, CN, NO2, SO3R″, halogen, substituted or unsubstituted phenyl, sulfonamide, halosulfonamide, and substituted or unsubstituted C1-C12 alkyl; R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C1-C12 alkyl, or unsubstituted C1-C12 alkyl; and R″ is hydrogen or substituted or unsubstituted C1-C12 alkyl, where the two R″ groups in CON(R″)2 may be independently selected; X is halogen; M is an alkali or alkaline earth metal; and n is the number of water molecules per molecule of the sulfonamide compound. The compound effectively suppresses odors pre-use, in use, and post-use for extended periods of time.
