Granular Laundry Detergent Composition for Accurate Small-Dose Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granular laundry detergents face challenges in accurate dosing and maintaining the correct ratio of ingredients per dose, particularly when using smaller volumes, leading to under-performance or waste due to under- or over-dosing.
Innovation Solution
A granular laundry detergent composition with a weight of 15 g to 45 g, comprising two types of particles with specific bulk densities, where 10% are high-density particles and 90% are lower-density particles, ensuring accurate dosing and maintaining ingredient ratios, packaged in recyclable materials with dosing devices for precise measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a larger dose volume is used, then dosing accuracy is improved, but product waste increases due to over-dosing
Solution Approach 1:
The invention changes the physical parameters of the detergent particles by creating a bimodal distribution of bulk densities (first plurality: 1101-3000 g/L, second plurality: 400-1100 g/L). This parameter change allows the mixture to flow and dose accurately at smaller volumes (15-45g) while maintaining the correct ingredient ratios, thereby reducing product waste from over-dosing.
2Loss of substance
If a smaller dose volume is used, then product waste is reduced, but dosing accuracy deteriorates
Solution Approach 1:
By modifying the bulk density parameters of the particles and creating a specific bimodal distribution, the invention enables smaller dose volumes (15-45g) to maintain accurate dosing. The free-flowing properties achieved through these parameter changes ensure that even small doses can be measured and dispensed accurately without compromising precision.
3Loss of substance
If a smaller dose volume is used, then product waste is reduced, but ingredient ratio maintenance deteriorates
Solution Approach 1:
The invention uses parameter changes in particle bulk density to create distinct physical characteristics for different ingredient particles. The high-density particles (1101-3000 g/L) and low-density particles (400-1100 g/L) can be separately controlled and dosed, ensuring that the correct ingredient ratios are maintained even in smaller dose volumes (15-45g), thereby preventing composition instability.
