Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundering products offer limited scent options and intensity control, with scents often fading quickly, and lack versatility in providing both fabric benefits and air freshening capabilities.
Innovation Solution
A functionalized substrate comprising 1-20% water-dispersible cellulose, 0.001-50% binder material, and microcapsules encapsulating perfumes, allowing for customizable scent intensity and longevity, as well as air freshening benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional laundering products are used with fixed perfume amounts, then manufacturing and formulation is simplified, but consumers cannot control scent intensity and scent options are limited
Solution Approach 1:
The perfume is segmented into individual microcapsules that can be independently controlled. Each microcapsule contains a discrete amount of perfume, allowing consumers to control scent intensity by adjusting the number of microcapsules used rather than changing the entire product formulation.
Solution Approach 2:
The product transitions from a static fixed-perfume formulation to a dynamic system where consumers can adjust perfume release by varying the number of microcapsules. This enables real-time customization of scent intensity without requiring multiple different product formulations.
2Adaptability or versatility
If consumers overdose or underdose detergent to control scent intensity, then scent customization is achieved, but fabric damage or insufficient cleansing occurs
Solution Approach 1:
By dividing the perfume into discrete microcapsules, the system allows precise control of scent intensity through quantity adjustment without affecting the amount of active cleansing ingredients. This segmentation isolates the scent control variable from the fabric care performance variables.
Solution Approach 2:
The microcapsules act as an intermediary carrier that delivers perfume independently of the detergent's cleansing function. Consumers can adjust the number of microcapsules without altering the detergent dosage, ensuring reliable fabric care while achieving desired scent intensity.
3Duration of action of moving object
If conventional laundering products are used, then fabric laundering benefits are provided, but scent longevity is poor and scents fade quickly
Solution Approach 1:
The perfume is pre-encapsulated in microcapsules attached to the detergent or fabric, creating a reservoir of scent that will be released over time. This preliminary encapsulation protects the perfume from premature evaporation or degradation, extending scent longevity without interfering with the laundry process.
Solution Approach 2:
The microcapsule shell provides a flexible protective barrier that controls perfume release. The shell maintains integrity during washing but allows controlled release during drying or wearing, extending scent duration without adding bulk or complexity to the laundry system.
4Adaptability or versatility
If microcapsules are incorporated into the substrate, then scent longevity and customization are improved, but device complexity increases
Solution Approach 1:
The microcapsule technology serves multiple functions simultaneously: it enables scent customization, extends scent longevity, and can be integrated into existing detergent or fabric substrates. This multi-functionality justifies the added complexity by delivering multiple benefits from a single technological approach.
Solution Approach 2:
The microcapsules serve as an intermediary layer between the substrate and the environment, providing controlled perfume release without requiring fundamental changes to the substrate structure. They can be surface-applied or incorporated into existing formulations, minimizing structural complexity while maximizing functional capability.
