Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Containers stacked one inside the other experience instability during handling and transport due to potential jamming and rotational movement.
Innovation Solution
The container base features radially outer recesses that engage with the stacking ribs of the container below, ensuring non-rotatable fixation and alignment, thereby enhancing stability by preventing jamming and rotational movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If containers are stacked one inside the other with conically shaped container walls, then space utilization is improved, but the container walls may jam and cause instability during handling and transport
Solution Approach 1:
The container wall is segmented by adding axially running stacking ribs distributed over the circumference on the inside of the container wall. These ribs create segmentation that prevents the conical container walls from jamming together while maintaining space utilization, as the ribs allow controlled separation between nested containers during handling and transport.
Solution Approach 2:
The solution introduces a new dimensional element by adding stacking ribs that extend axially along the container wall. This transforms the problem from a two-dimensional surface contact issue to a three-dimensional structural solution, where the ribs provide additional support surfaces and prevent wall jamming while maintaining compact stacking.
2Stability of the object's composition
If stacking ribs are added to prevent jamming, then wall jamming is prevented, but rotational movement and positional instability occur during handling and transport
Solution Approach 1:
The container base is designed with asymmetric features including at least one recess in the radially outer area and an axially projecting base with interruptions that form recesses. These asymmetric features engage with the stacking ribs to prevent rotational movement, as the recesses create non-rotatable engagement points that fix the angular position of nested containers relative to each other.
Solution Approach 2:
The stacking ribs act as intermediary elements between the container wall and the container base. They extend from the container wall down to engage with the recesses in the base, serving as mechanical mediators that transmit and fix the positional relationship between nested containers, preventing both jamming and rotational movement.
3Reliability
If the container base has recesses for non-rotatable fixation, then rotational stability is improved, but the complexity of the base structure increases
Solution Approach 1:
Instead of modifying the entire container base uniformly, the solution applies local quality by adding recesses only in the radially outer area of the base where they are needed for engagement with stacking ribs. The base maintains its simple overall structure with localized features added only where necessary for rotational fixation, minimizing overall complexity.
Solution Approach 2:
The recesses in the base are designed to nest with the stacking ribs extending from the container wall. This nested arrangement allows the fixation mechanism to be integrated within the existing container structure, where the stacking ribs that already exist for jamming prevention also serve the additional function of engaging with the base recesses to prevent rotation.

AI summary
The invention relates to a container (1) comprising a container wall (2), a container base (3) and a container opening (4), the container wall (2) extending in a substantially conically manner from the base to the opening and the inner face of the container wall (2) having spaced stacking ribs (5) running axially around the circumference. According to the invention, the container is developed in that the outer radial region of the exterior of the container base (3) is provided with at least one cavity (10), into which at least one stacking rib of a container (1) located below can engage when several containers (1) are stacked inside one another, thus fixing the containers (1) and preventing them from rotating in relation to one another. This improves the positional stability of the stacked containers.
