Malodor-Reduction Particles for Long-Lasting Laundry Freshness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current malodor control technologies for laundry articles primarily mask odors rather than effectively reducing them, leading to unsatisfactory freshness and potential negative impacts on the wearer and others due to the limited nature of existing solutions.
Innovation Solution
A composition of particles comprising a carrier, perfume, and malodor reduction materials with specific weight percentages and a Blocker Index, designed to effectively reduce malodor perception and eliminate unpleasant smells in laundry articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If garments are worn multiple times between washings, then laundry frequency is reduced, but malodor accumulates and freshness is lost
Solution Approach 1:
The patent applies odor-binding materials to laundry articles in advance, before malodors have a chance to accumulate to unacceptable levels. This preliminary action allows the binding materials to be present and ready to capture malodor molecules as soon as they are generated during wear, enabling extended wear periods without significant malodor accumulation.
Solution Approach 2:
The patent establishes continuous malodor control by having odor-binding materials continuously present on the laundry articles during storage and wear. The binding materials maintain their odor-capturing capability over time, providing ongoing protection against malodor accumulation and enabling garments to be worn multiple times while maintaining freshness.
2Ease of operation
If laundry articles are stored for weeks or months, then wardrobe management is simplified, but malodor develops and freshness deteriorates
Solution Approach 1:
The patent applies odor-binding materials to laundry articles before storage, providing preliminary protection against storage-induced malodors. The binding materials are positioned on the articles in advance, ready to capture any malodor molecules that may develop during extended storage periods, thereby maintaining freshness without requiring frequent wardrobe rotation.
Solution Approach 2:
The patent enables laundry articles to self-protect against storage malodors through the incorporated odor-binding materials. The binding materials continuously monitor and capture malodor molecules generated during storage, allowing the articles to maintain freshness autonomously without requiring external intervention or frequent handling.
3Ease of operation
If soiled laundry is stored in hampers or bags, then laundry handling is convenient, but malodor increases to repulsive levels
Solution Approach 1:
The patent introduces odor-binding materials as intermediary substances in soiled laundry storage containers. These binding materials act as mediators between the malodorous soiled laundry and the storage environment, capturing malodor molecules through adsorption or chemical binding, thereby reducing malodor levels to acceptable ranges while maintaining the convenience of centralized laundry storage.
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 described composition effectively reduces malodor perception, providing long-lasting freshness and improving the overall experience of wearing and storing laundry articles by addressing the limitations of existing malodor control technologies.
