Aluminum-Plastic Composite Wall Element for Raised Beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall elements for raised beds lack full rigidity in both vertical and horizontal directions, and existing solutions often have visible or difficult-to-reach connecting elements, and are prone to corrosion or short lifespan.
Innovation Solution
The use of flat, plate-like wall elements made from aluminum-plastic composite material with edge stabilization and connecting strips bent at specific angles, allowing for full rigidity and easy assembly without visible screws, and featuring a design that can be folded and assembled on-site without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If wall elements are made with connecting areas and angle plates for rigidity, then structural stability is improved, but visible screws and complex connections are created
Solution Approach 1:
The connecting strips are integrated directly into the wall element structure, merging the connection function with the wall panel itself. This eliminates separate angle plates and visible screws, achieving structural stability through integrated L-shaped connecting strips that form flush joints with adjacent wall elements.
Solution Approach 2:
The visible fastening elements (screws and angle plates) are extracted from the exterior design and hidden within the joint structure. The connecting strips are designed to be concealed within the joint between wall elements, removing the aesthetic drawback of visible connections while maintaining structural integrity.
2Strength
If wall elements use tongue-and-groove connections with connecting elements, then joint strength is improved, but connecting elements become difficult to reach or visible from outside
Solution Approach 1:
The wall elements are designed to be self-aligning and self-securing. The L-shaped connecting strips automatically form the joint structure when wall elements are assembled, eliminating the need for complex tongue-and-groove mechanisms and making the connection process simple and accessible without requiring difficult-to-reach fastening operations.
3Ease of manufacture
If wall elements are made from materials that can be folded on-site, then ease of assembly is improved, but material strength and rigidity may be compromised
Solution Approach 1:
The wall elements utilize composite material construction that combines flexibility for folding with strength for structural integrity. The material is designed to be foldable along predetermined lines for easy on-site assembly while maintaining sufficient strength to support the wall structure and resist corrosion through materials like aluminum-plastic composite or coated metals.

AI summary
The invention relates to a wall element (30, 30'), which has rectangular and/or square main surfaces (1) and which is made of a plate-like flat material, for the wall of stable shells or container shells (40) for various goods, which stable shells or container shells have a parallelepiped shape and in particular can form surrounding walls of raised beds, wherein at least one further respective similarly designed wall element (30') can be connected laterally to two of the sides of the wall element that are opposite each other in order to form a common edge (45) of the stable shell, wherein along the two said sides of the main surface (1) a respective edge stabilization strip (11, 11') is bent by an angle Ca corresponding to half the interior edge angle (a) of the stable shell, wherein furthermore the wall element, which is preferably made of a metal-to-plastic composite material, has, in addition to the edge stabilization strips, connecting strips (12, 12') along the two other sides opposite each other, which connecting strips are bent from the main surface (1) of the wall element by an angle of 90° in the same direction, and wherein the two edge stabilization strips (11, 11') are shortened by a small amount (b) at both ends. The invention further relates to the stable shells or container shells (40) to be formed by means of the wall elements and to the production thereof.
