Detergent Tablet Folding Carton Layout for Stable High-Fill Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent packaging systems face challenges in ensuring transport and storage stability of detergent tablets while minimizing the use of non-recyclable and non-biodegradable materials, and they often require excessive packaging to maintain chemical and physical integrity.
Innovation Solution
A detergent packaging form featuring an outer package with a high fill level, a resealable design, and use of recyclable materials like cardboard or corrugated board, combined with void volumes in the side walls to enhance physical and chemical stability, and water-soluble film wrappers for tablets.
Engineering Contradictions & Design Principles
Engineering 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 environmental friendliness deteriorates due to non-recyclable and non-biodegradable materials
Solution Approach 1:
The patent changes the material parameter from water-insoluble polymer films to water-soluble packaging materials. This allows the packaging to maintain protective function during transport and storage while enabling easy disposal and biodegradation, thus resolving the contradiction between stability and environmental friendliness
Solution Approach 2:
The patent employs disposable, biodegradable packaging materials that can be safely discarded after use. The water-soluble nature of the packaging allows it to decompose naturally in the environment, eliminating the need for recycling infrastructure while maintaining protection during the product's shelf life
2Loss of substance
If outer packaging uses high fill level with detergent tablets arranged characteristic of the invention, then packaging material usage is reduced, but ensuring transport and storage stability becomes more challenging
Solution Approach 1:
The patent changes the spatial arrangement dimension by orienting detergent tablets vertically with their axes perpendicular to the base of the outer packaging. This dimensional reorientation allows tablets to be stacked efficiently at high fill levels while the vertical orientation provides natural stability and prevents rolling or shifting during transport
Solution Approach 2:
The patent employs asymmetric orientation of detergent tablets within the outer packaging, where tablets are positioned with specific orientations relative to the packaging base. This asymmetric arrangement optimizes space utilization for high fill level while the specific orientation patterns provide stability through interlocking and prevention of random movement
3Ease of manufacture
If outer packaging is designed as one-piece folding carton with flat base, then ease of manufacture and opening is improved, but structural stability may be compromised
Solution Approach 1:
The patent segments the outer packaging into distinct functional elements: a flat base for stability, side walls for containment, and a lid for closure. The one-piece construction integrates these segments while maintaining ease of assembly and opening, balancing manufacturability with structural integrity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The packaging system provides improved transport and storage stability, reduces packaging material usage, and maintains chemical integrity of detergent tablets, while being environmentally friendly.
Implementation Method 1
waterproof packaging materials, such as flow packs based on water-insoluble polymer films
Implementation Method 2
This air volume, along with the aforementioned fin seams, ensures the physical integrity of the dosing units under mechanical stress due to its damping effect

AI summary
A detergent packaging form comprising a) an outer packaging in the form of a folding box, with a base, a lid and side walls connecting the base and lid, b) cuboid detergent tablets with three different edge lengths and three double axes of rotation, wherein i) the outer packaging has a fill level of 85% to 99% by volume and ii) the outer packaging contains at least two detergent tablets arranged in the outer packaging such that the axes of rotation of the detergent tablets, along which they have the lowest tablet hardness, run parallel to the base of the outer packaging.
