Laundry Dose Blister Pack for Accurate Detergent Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers tend to overdose on concentrated particulate detergent compositions due to difficulty in accurately dosing, leading to inefficiencies and environmental impact.
Innovation Solution
A packaged product with individual reservoirs containing pre-measured doses of non-spherical, high-surfactant, hard-coated particles that provide a slow and predictable flow, along with a rigid support frame for easy dispensing, minimizing residue and allowing for precise dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If concentrated particulate detergent compositions are provided without pre-measured doses, then consumers can use the composition freely, but consumers tend to overdose leading to waste and environmental impact
Solution Approach 1:
The detergent composition is divided into individual pre-measured doses contained in separate reservoirs. Each reservoir holds a specific amount of concentrated particulate detergent, allowing consumers to dispense exactly one dose at a time without risking overdose. This segmentation eliminates the need for consumers to measure the detergent themselves while preventing waste from excessive use.
2Measurement precision
If pre-measured doses are provided in individual reservoirs, then dosing accuracy is improved, but device complexity increases
Solution Approach 1:
The packaging is segmented into multiple individual reservoirs, each containing a pre-measured dose. This segmentation inherently provides dosing accuracy without requiring complex measuring mechanisms, dispensing controls, or electronic dosing systems. The complexity is minimized by using simple sealed reservoirs that can be manually opened.
Solution Approach 2:
The dosing action is performed in advance during manufacturing rather than at the point of use. Each reservoir is pre-filled with the exact amount of detergent needed, eliminating the need for complex dosing mechanisms in the consumer device. The measurement and portioning are completed during production, simplifying the end-use device.
3Quantity of substance
If fine particulate detergent is used in reservoirs, then the composition fills the reservoirs completely, but the inner surfaces become coated with fine dusting affecting transparency
Solution Approach 1:
The particle size parameter is changed from fine to large particles. This parameter change allows the reservoirs to remain transparent because large particles do not form a fine dusting coating on the inner surfaces.同时, the large particles still effectively fill the reservoir volume when properly designed and arranged.
4Adaptability or versatility
If liquid detergent formulations are used, then dosing flexibility is provided, but liquid coats the inner surfaces of reservoirs leaving residue
Solution Approach 1:
The physical state parameter is changed from liquid to concentrated particulate form. This parameter change eliminates the residue problem because solid particles do not coat the inner surfaces of reservoirs like liquids do. The concentrated particulate formulation maintains dosing flexibility through the pre-measured individual doses in reservoirs.
