Container Wall Interlock Mechanism for Stable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container systems, such as those described in EP 0 694 012 B1, face instability when second sections are mounted on screw heads, leading to either unstable walls or difficulty in smooth removal, as they cannot be placed on screw heads without risking instability or using adhesives that prevent easy disassembly.
Innovation Solution
Securing each second section to the bottom member with screws and designing the second part of the first section to have a bent portion that allows the screw head to be received, enabling steady fixation and support from both screw heads and the mid portion, allowing for a range of tilting angles for easy assembly and disassembly, and using clamps to maintain wall position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the second section is mounted on screw heads, then the assembly is simple, but the wall stability deteriorates
Solution Approach 1:
The patent introduces a bearing surface on the bottom member that acts as an intermediary between the screw heads and the second section. This bearing surface provides a stable support area that distributes the load from the second section across multiple screw heads rather than concentrating it on individual heads, thereby maintaining both assembly simplicity and wall stability.
2Stability of the object's composition
If adhesive is used to mount the second section, then wall stability is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The patent segments the connection system into distinct functional elements: screws for attachment, a bearing surface for load distribution, and a defined bearing area. This segmentation allows the second section to be securely mounted with stable walls while maintaining ease of disassembly, as the mechanical screw connection can be easily undone without the permanent bonding effects of adhesive.
3Reliability
If the second section is securely fixed to prevent removal, then reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
The patent creates a dynamic balance in the fixation system where the bearing surface and bearing area are designed to provide sufficient friction and support for reliable operation during use, while the underlying screw mechanism remains accessible and operable for easy removal when needed. The design allows the connection to be as strong as required during service but as easy to disconnect as required for maintenance.

AI summary
A system for creating a container having a bottom and four lateral walls comprises a bottom member (1), four walls (2) and an arrangement (3) for interlocking said walls with respect to said bottom member so as to create a container. The arrangement comprises for each wall a first section (4) and the bottom has for each outer border thereof a second section (10). The second section allows introduction of the first section therein with a corresponding wall tilted outwards from a centre of a container to be created and has a part (12) forming a stop to the first section preventing lifting of the wall with respect to the bottom member in a vertical position of the former.
