Laundry scent additive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers who prefer strong perfume scents in their laundry often overuse laundry products, leading to a need for a cost-effective, independent perfume scent additive that can provide desired freshness without interference from other laundry products.
Innovation Solution
A composition consisting of 80-91% polyethylene glycol with a molecular weight of 5,000 to 11,000, combined with 2-12% free perfume and 2-12% friable perfume microcapsules, shaped into pastilles with a mass of 0.95 mg to 2 g, which can be used as a unit dose to achieve the desired scent level in laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If consumers overuse laundry detergent and fabric softener to achieve desired scent strength, then the perfume scent intensity is improved, but the cost increases and interference from other laundry products occurs
Solution Approach 1:
The patent extracts the perfume scent function from traditional laundry products by providing a separate, dedicated scent additive composition. This allows consumers to add only the necessary perfume scent without using excess detergent or softener, thereby reducing cost while achieving the desired scent intensity.
Solution Approach 2:
The invention segments the laundry treatment function into separate components: cleaning agents and a dedicated scent additive. The scent additive composition contains perfume, encapsulated perfume, and fragrance boosters that work independently to enhance scent without the need to overuse other laundry products.
2Illumination intensity
If consumers overuse laundry detergent and fabric softener to achieve desired scent strength, then the perfume scent intensity is improved, but the interference from other laundry products increases
Solution Approach 1:
The patent extracts the perfume scent function from traditional laundry products by providing a separate, dedicated scent additive composition. This allows consumers to add only the necessary perfume scent without using excess detergent or softener, thereby reducing cost while achieving the desired scent intensity.
3Ease of operation
If a perfume scent additive product is provided to achieve desired freshness independently, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple fragrance delivery mechanisms (free perfume, encapsulated perfume, and fragrance boosters) into a single integrated composition. This unified formulation simplifies consumer operation by providing one product that delivers comprehensive scent enhancement without requiring complex application procedures or multiple separate products.
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 solution provides a balanced and pleasant scent experience while ensuring physical and chemical stability of the pastilles, preventing overapplication of perfume and minimizing interference from other laundry actives, thus addressing the need for enhanced freshness in a cost-effective manner.
