Pivotable Coupling Elements for Stackable System Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable system containers lack stability when multiple containers are stacked, leading to detachment issues due to simple coupling designs, limiting their modular use and stability.
Innovation Solution
The coupling elements are pivotably attached to the top of the system container, allowing them to be swiveled between a protruding and recessed position, enabling secure interaction with identical containers while allowing for the stacking of different designs, and providing a stable, flat surface for storage or work without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coupling elements are fixed in a protruding position to ensure stable stacking, then stacking stability is improved, but the top surface becomes obstructed and cannot be used as a storage or work surface
Solution Approach 1:
The coupling elements are designed to be movable rather than fixed, allowing them to pivot between a protruding position (for stable stacking) and a recessed position (for top surface usability). This dynamic adjustment resolves the contradiction by enabling the system to switch between different functional states based on operational requirements.
2Reliability
If coupling elements are designed with a specific fastening system for stable connection, then connection stability is improved, but the system becomes less modular when stacking different container designs
Solution Approach 1:
The coupling elements are designed with a universal interface that can accommodate different container designs while maintaining stable connections. The standardized coupling mechanism works across various container types, enabling both stable connections and modular versatility simultaneously.
3Ease of manufacture
If simple coupling elements are used to reduce device complexity, then ease of manufacture is improved, but stacking stability and load-bearing capacity deteriorate
Solution Approach 1:
The coupling elements incorporate a pivoting mechanism that adds minimal complexity but dramatically improves stability. The dynamic locking capability allows simple components to achieve reliable, stable connections that can bear significant loads without requiring complex structural designs.

AI summary
The invention relates to a stackable system container (1) having a base part (2) and having a cover part (3) fastened to the base part (2), and having at least two coupling elements (9a, 9b) which protrude upward beyond a top side (7) of the system container (1) and which each have at least one recess (10a, 10b) for the engagement of a coupling device (11a; 11b) of an identical system container (1) arranged thereabove and which are arranged at opposite ends of the top side (7) of the system container (1). To permit both dimensionally stable and connected stacking of structurally identical system containers and also modular stacking of different system containers, the coupling elements (9a, 9b) are fastened pivotably to the top side (7) of the system container (1) such that, in a pivoted-in position, they do not protrude beyond the top side (7) of the system container.
