Capsule Mixing System for Concentrated Detergent Solutions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing cleaning and personal care products result in significant environmental impact due to the transportation and storage of large quantities of water, as well as the use of non-biodegradable plastic packaging, which contributes to greenhouse gas emissions and pollution.
Innovation Solution
A system and method for preparing mixed solutions, such as shampoo, using a mixing tank with a motorized mixing rod and heating element, a capsule receptacle for concentrate, and a controller to operate the mixing process according to a specified profile, allowing for the creation of customized products in a consumer setting, reducing the need for single-use packaging and minimizing environmental footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If finished cleaning products are purchased in single-use packages, then product availability and convenience are improved, but environmental impact and storage requirements worsen due to water transportation and plastic packaging
Solution Approach 1:
The finished product is segmented into two components: a concentrated active ingredient formulation and a bulk solvent (water). Only the concentrate is packaged and transported, while the solvent is added locally at the point of use, dramatically reducing transportation and storage requirements while maintaining product availability.
Solution Approach 2:
The bulk water component is extracted from the finished product formulation and removed from the packaging system. Only the essential active ingredients and additives are packaged in concentrated form, eliminating the need to transport and store large volumes of water in plastic containers.
2Manufacturing precision
If concentrates are mixed at production facilities, then product quality and consistency are improved, but device complexity and infrastructure requirements worsen
Solution Approach 1:
The consumer unit is equipped with simple mixing infrastructure (container, concentrate dispenser, and water addition capability) that enables local mixing of the concentrate with water. This self-service approach maintains product quality through controlled mixing while eliminating the need for complex centralized production and distribution infrastructure.
Solution Approach 2:
The concentrate is formulated with specific viscosity, stability, and solubility parameters that enable it to be stored in concentrated form and then easily mixed with water at the consumer level. These parameter optimizations allow quality control to be shifted from centralized production to distributed consumer use.
3Ease of operation
If large quantities of water are transported in finished products, then product readiness and convenience are improved, but transportation costs and environmental footprint worsen
Solution Approach 1:
The product system is segmented into a transported concentrate component and a locally added water component. This segmentation eliminates the need to transport bulk water, reducing transportation energy consumption by approximately 90% or more while maintaining product readiness through simple local mixing.
Solution Approach 2:
The concentrate is formulated with optimized concentration parameters (typically 5-20% active ingredients) that allow it to be transported in small volumes and then diluted with water at the point of use, dramatically reducing the energy required for transportation while ensuring the final product meets quality standards.

AI summary
A system and methods are provided for preparing a mixed solution, the system includes: a mixing tank (302) with a motorized mixing rod (306) and a heating element (312), and 2) a capsule receptacle (106) to receive a capsule of a concentrate. The capsule receptacle has a capsule inlet (324) for receiving water into the capsule and a capsule outlet (326) for releasing the water with the concentrate to the mixing tank. A controller (340) is configured to operate the mixing rod and the heating element to generate a mixed solution from the water and the concentrate, according to a mixing profile. An output pump (330) is operated to pump the mixed solution from the mixing tank to a detachable bottle.
