Malodor Reduction Particles with Blocker Index for Laundry Freshness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current malodor control technologies for laundry articles typically mask odors rather than effectively reducing them, leading to unsatisfactory freshness and potential negative impacts on the wearer's experience and perception.
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 without overpowering the scent of laundry articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If malodor control technologies are applied to laundry articles, then malodor perception is reduced, but the original scent of the laundry article is masked or interfered with
Solution Approach 1:
The patent extracts and removes malodor molecules from the laundry article surface through the action of malodor control agents, separating the harmful malodor substances from the desirable laundry scent, thereby reducing malodor perception without masking the original fragrance
Solution Approach 2:
The patent introduces malodor control agents as intermediary substances that interact with malodor molecules to neutralize or remove them, allowing the original laundry scent to remain unaffected while eliminating the harmful malodor perception
2Loss of time
If garments are worn multiple times between washings to reduce laundry frequency, then time and resources are saved, but malodor accumulates on the garment
Solution Approach 1:
The patent applies malodor control treatment to laundry articles in advance, creating a protective effect that prevents malodor accumulation during multiple wears, allowing garments to be worn repeatedly without developing unpleasant odors
Solution Approach 2:
The patent provides continuous malodor control protection that maintains garment freshness throughout multiple wearing cycles, enabling extended use between washings while preventing malodor buildup through sustained active protection
3Ease of operation
If laundry articles are stored for extended periods before wearing, then convenience is improved, but malodor develops during storage
Solution Approach 1:
The patent applies malodor control treatment before storage, creating protective properties that prevent malodor development during extended storage periods, allowing convenient advance preparation without subsequent odor problems
Solution Approach 2:
The patent provides preemptive protection against storage malodor by applying malodor control agents before the storage period begins, cushioning or preventing the development of unpleasant odors that would otherwise occur during extended storage
