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

VSEngineering 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

Engineering Contradiction:
Improvestacking stabilityVSAvoidtop surface usability
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveconnection stabilityVSAvoidmodular stacking capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvecoupling element simplicityVSAvoidstacking stability
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #15Dynamics

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.
