Multi-chamber Detergent Packs with Detachable Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single dose detergent packs lack scalability and customizability, often providing too much or too little detergent for varying wash loads and not matching detergent types with specific soiling needs, leading to inefficiency and waste.
Innovation Solution
Multi-chamber single dose packs with detachable and reattachable chambers, allowing for customizable combinations of detergent compositions to match load size and soiling requirements, using water-soluble films and adhesives for easy separation and recombination of chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single dose pack provides a fixed amount of detergent, then it is easy to carry and convenient to use, but it cannot be adjusted to match varying wash load sizes, leading to waste or insufficient cleaning
Solution Approach 1:
The detergent pack is divided into multiple detachable chambers, each containing a separate detergent composition. Users can separate the chambers and select only the needed amount for their specific wash load, transforming a fixed single-dose pack into a scalable multi-dose system that maintains convenience while enabling adaptation to different load sizes
Solution Approach 2:
The pack structure transitions from a static fixed configuration to a dynamic reconfigurable system. Chambers can be detached and reattached in various combinations, allowing the detergent quantity to be dynamically adjusted based on wash requirements while preserving the ease of single-dose operation
2Ease of manufacture
If a single dose pack contains a specific detergent type, then it is simple to manufacture, but it cannot match different detergent types to specific soiling needs, reducing cleaning effectiveness
Solution Approach 1:
Different detergent compositions targeted at specific soiling types (e.g., grease, starch, protein stains) are placed in separate detachable chambers. Each chamber can be manufactured independently using simple processes, yet the segmented structure enables users to assemble customized detergent combinations matching their specific soiling needs
Solution Approach 2:
Each chamber contains a detergent composition with specialized properties optimized for specific soiling types. This local quality differentiation within the pack structure allows users to select and combine chambers based on the particular stains present in their wash load, enhancing cleaning effectiveness while maintaining manufacturing simplicity
3Stability of the object's composition
If a single dose pack is designed as a single integrated unit, then it maintains structural integrity, but it lacks the flexibility to be customized for different washing requirements
Solution Approach 1:
The pack is segmented into multiple chambers that are detachable yet maintain structural integrity when connected. Each chamber remains stable and intact during handling, but can be separated and recombined in different configurations, providing both structural reliability and customization flexibility
Solution Approach 2:
Water-soluble adhesive elements act as intermediaries between chambers, allowing chambers to be firmly attached when needed for structural integrity, yet easily separated when customization is required. The adhesive provides a reversible bonding mechanism that maintains stability while enabling adaptability
4Adaptability or versatility
If chambers are made detachable for customization, then flexibility is improved, but the risk of chamber separation or loss increases
Solution Approach 1:
Water-soluble adhesive elements serve as intermediaries that provide strong yet reversible bonding between chambers. The adhesive ensures chambers remain securely attached during handling and storage, reducing separation risk, while still allowing easy detachment when customization is needed, balancing reliability with flexibility

AI summary
A multi-chamber single dose pack includes a first water-soluble film, a second water-soluble film adhered to the first film, a first chamber and second chamber formed by the first film and the second film, a first detergent wash composition in the first chamber, a second detergent wash composition in the second chamber, a perforated tear line between the two chambers allowing separation of the two chambers by hand without opening either chamber, and a water-soluble adhesive disposed along an outward-facing portion of either or both of the first and second films. The water-soluble adhesive is configured to allow the attachment of at least one further chamber including a further wash composition.
