Plastic Transport Container with Filled Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic transport containers face challenges in increasing stacking load without compromising elasticity or ease of recycling, as additional ribs or steel reinforcements either reduce durability or complicate recycling and increase weight.
Innovation Solution
Applying stable, rigid plastic panels filled with additives such as glass fibers or polyamide to the exterior of plastic transport containers, which are then supported by existing ribs, enhances stability and stacking capacity without altering the container's elasticity or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials are used to increase stacking load, then the stacking load capacity increases, but the products break more quickly due to material brittleness
Solution Approach 1:
The invention applies panels made of plastic filled with stability-enhancing additives (such as glass fibers, hemp fibers, steel fibers, talcum, or chalk) to the outside of at least two opposite side walls. This composite structure combines the elasticity of the base plastic container with the rigidity of the filled panels, achieving increased stacking load capacity while maintaining product durability and preventing brittleness.
2Strength
If additional ribs are introduced to increase stacking load, then the stacking load increases by 20% to 30%, but the containers become significantly more difficult to clean and their weight increases
Solution Approach 1:
Instead of adding structural ribs that create cleaning difficulties, the invention applies filled plastic panels to the existing side walls. This approach increases stacking load capacity by at least 100% while maintaining the smooth outer surface of the container, thereby preserving ease of cleaning without compromising strength.
3Strength
If steel reinforcements are used to increase stacking load, then the strength increases, but the cost increases significantly and recycling becomes difficult
Solution Approach 1:
The invention uses panels made of plastic filled with various additives (including glass fibers, hemp fibers, steel fibers, talcum, or chalk) applied to the container exterior. This composite solution achieves the required strength increase while maintaining recyclability, as the filled plastic panels can be processed together with the base container, avoiding the recycling complications associated with steel-plastic combinations.
4Strength
If more rigid materials are used to meet demand for greater stacking loads, then the stacking load capacity increases, but the elasticity of the transport container is compromised
Solution Approach 1:
The invention applies panels made of plastic filled with stability-enhancing additives to the outside of at least two opposite side walls. This composite structure allows the base container to remain made of elastic plastic material while the filled panels provide the additional rigidity needed for higher stacking loads, thus maintaining container elasticity while meeting the demand for greater stacking capacity.

AI summary
The invention relates to a transport container which is made of plastic and has side walls which rise up from a bottom part and are reinforced on their outwardly facing surface by vertical and/or horizontal ribs which protrude from the walls and are characterized in that plates made of plastic filled with stiffness-increasing additives are applied to the outer side of at least two opposing side walls.
