Detergent Tablet Folding Box Layout for High-Fill Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent packaging solutions, particularly for tablets, face challenges in ensuring transport and storage stability while being ecologically sustainable, as they often use non-biodegradable materials and create unnecessary air volume, leading to physical and chemical instability.
Innovation Solution
A detergent presentation pack featuring a folding box outer packaging with high filling density, utilizing corrugated cardboard and hollow volumes in the side walls, along with cuboidal tablets aligned to maximize stability, and optionally using water-soluble film packaging, to enhance physical and chemical stability.
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 ecological sustainability deteriorates due to non-biodegradable materials
Solution Approach 1:
The invention divides the packaging system into two parts: a biodegradable outer packaging (cardboard box) and individual flow packs for each tablet. This segmentation allows the outer packaging to be eco-friendly while the inner flow packs provide the necessary protection for each tablet, resolving the contradiction between sustainability and stability.
Solution Approach 2:
The invention introduces an intermediary packaging structure where the outer cardboard box serves as a protective container for multiple flow packs. This intermediary structure provides the necessary mechanical protection and moisture barrier while being biodegradable, thus maintaining stability without compromising ecological sustainability.
2Strength
If flow packs enclose detergent tablets with considerable air volume, then physical integrity is improved through damping effect, but packaging material use and environmental impact increase
Solution Approach 1:
The invention extracts the excessive air volume from the packaging system by using compact flow pack design. The flow packs are designed to fit tightly around the tablets without unnecessary air space, eliminating the damping effect provided by air while reducing packaging material consumption and environmental impact.
3Stability of the object's composition
If water-insoluble polymer films are used for packaging, then chemical stability is improved by preventing water ingress, but biodegradability deteriorates
Solution Approach 1:
The packaging system is segmented into an outer biodegradable cardboard box and inner flow packs. The outer box provides the primary barrier against moisture and is fully biodegradable, while the inner flow packs provide additional protection for each tablet. This segmentation allows chemical stability to be maintained without requiring entirely non-biodegradable packaging.
Solution Approach 2:
The packaging system uses composite material construction combining biodegradable cardboard for the outer structure with water-insoluble polymer films for the inner flow packs. This composite approach provides both chemical stability through the polymer barrier and biodegradability through the cardboard outer layer, resolving the contradiction between these two requirements.

AI summary
A detergent presentation pack includes outer packaging in the form of a folding box, having a base surface, a cover surface and side walls connecting the base surface and the cover surface, and cuboidal detergent tablets with three different edge lengths and three 2-fold axes of rotation. The degree of filling of the outer packaging is from 85% by volume to 99% by volume, and the outer packaging contains at least two detergent tablets, which are arranged in the outer packaging such that the axes of rotation of the detergent tablets along which the latter have the lowest level of tablet hardness run parallel to the base surface of the outer packaging.
