Solution Overview

Problem

Existing detergent packaging systems, particularly those using water-soluble containers and tablets, face issues with transport and storage stability, chemical degradation, and ecological unsustainability due to non-biodegradable materials, while also being inconvenient for consumers.

Innovation Solution

A detergent packaging form featuring cuboid-shaped detergent granules oriented within a folding carton made of recyclable materials, with a resealable design and specific surface roughness, allows for high fill levels and easy handling, ensuring stability and minimal packaging material use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If detergent tablets are packaged in individual flow packs with water-insoluble polymer films, then transport and storage stability is improved, but packaging material usage increases and environmental friendliness deteriorates

Engineering Contradiction:
Improvetransport and storage stabilityVSAvoidpackaging material usage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The invention divides the packaging system into two levels: an outer packaging containing multiple detergent tablets, and minimal individual wrapping only where necessary. This segmentation allows reduction of total packaging material while maintaining stability through the outer container's structure and design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the water-insoluble polymer film wrapping from individual detergent tablets, removing this harmful packaging element entirely. Instead, tablets are placed directly in the outer packaging or with minimal biodegradable wrapping, eliminating the need for non-biodegradable materials while maintaining adequate protection.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If detergent tablets are packaged in individual flow packs with water-insoluble polymer films, then transport and storage stability is improved, but environmental friendliness deteriorates

Engineering Contradiction:
Improvetransport and storage stabilityVSAvoidenvironmental friendliness
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention removes water-insoluble polymer films from the packaging system entirely, extracting this harmful element that prevents biodegradation. The solution uses only biodegradable and environmentally friendly materials, eliminating the negative environmental impact while maintaining adequate protection for detergent tablets during transport and storage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the material parameters of the packaging from water-insoluble polymers to biodegradable materials. This parameter change transforms the packaging system from environmentally harmful to eco-friendly, allowing natural decomposition after use while still providing necessary protection for the detergent tablets.

Inventive Principle:
Principle #35Parameter changes

3Loss of substance

If detergent tablets are packaged without individual flow packs, then packaging material usage is reduced, but transport and storage stability deteriorates

Engineering Contradiction:
Improvepackaging material usageVSAvoidtransport and storage stability
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The invention merges multiple detergent tablets into a single outer packaging container, combining protection functions for multiple units. The outer packaging provides collective protection against mechanical stress and moisture, replacing the need for individual protective wraps while maintaining adequate stability through proper container design and material selection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention changes the protective mechanism from individual polymer film barriers to collective protection through outer packaging structure, material properties, and design features. This parameter change maintains stability through the outer container's structural integrity and appropriate material selection rather than relying on individual wraps for each tablet.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If cuboid detergent molded bodies are arranged with end faces contacting the base surface, then ease of removal is improved, but packaging design complexity increases

Engineering Contradiction:
Improveease of removalVSAvoidpackaging design complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention uses the asymmetric geometry of cuboid detergent molded bodies, specifically their end faces with smaller areas, to create a preferred orientation for removal. By arranging tablets with end faces contacting the base surface, the design exploits the asymmetric shape to facilitate easy grasping and removal from the outer packaging, transforming a geometric feature into a functional advantage.

Inventive Principle:
Principle #4Asymmetry

AI summary

A detergent packaging form comprising: a) an outer packaging with a base, a lid opposite the base, and side surfaces connecting the base and lid; b) cuboid detergent bodies with a top, a bottom, two shell sides connecting the top and bottom, and two end faces, different from the shell sides, connecting the top and bottom, wherein: i) the outer packaging contains at least two detergent bodies; ii) the end faces of the detergent bodies have a smaller area than their shell sides; iii) the detergent bodies are arranged in the outer packaging such that all detergent bodies have one end face in direct contact with the base of the outer packaging; and iv) the outer packaging is designed such that at least three sides of each detergent body are visible when opened.
