Stackable Container Assembly Interlocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable container systems lack a structural mechanism to interlock containers securely, leading to movement and instability when stacked.
Innovation Solution
A stackable container assembly featuring first and second containers with specific recessed and projecting areas on their upper and lower surfaces, respectively, allowing for interlocking engagement that limits movement between stacked containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If containers are stacked one on top of another without interlocking structure, then stacking is simple and quick, but movement and instability occur between stacked containers
Solution Approach 1:
The container surfaces are segmented into projecting areas and recessed areas that function as interlocking elements. These segmented features are integrated into the container walls to provide stacking stability without requiring separate interlocking components.
Solution Approach 2:
The recessed areas of one container receive the projecting areas of the container below it, creating a nested interlocking relationship. This allows containers to stack securely with the projections of upper containers fitting into the recesses of lower containers.
2Reliability
If interlocking structure with projections and recesses is added to containers, then stability and movement limitation are improved, but manufacturing complexity increases
Solution Approach 1:
The interlocking features (projections and recesses) are merged directly into the container wall structure during manufacturing. This integration eliminates the need for separate interlocking components and simplifies the manufacturing process while ensuring reliable stacking.
Solution Approach 2:
The container walls serve multiple functions: containing stored materials and providing interlocking features for stacking. The projecting and recessed areas are formed as integral parts of the container structure, making the containers universally stackable without additional components.
3Adaptability or versatility
If containers of different sizes are stacked using the same interlocking mechanism, then versatility and adaptability are improved, but alignment precision becomes more difficult to maintain
Solution Approach 1:
The interlocking mechanism uses standardized projecting and recessed areas that can accommodate containers of different sizes. The same basic interlocking features work for both smaller and larger containers, providing universal stacking capability across different container dimensions.
Solution Approach 2:
The interlocking features are positioned at specific locations on the container surfaces where they can accommodate size variations. The projecting and recessed areas are strategically placed to ensure proper alignment and engagement regardless of the container size being stacked.

AI summary
A stackable container assembly includes a first container and a second container. The first container has an upper surface with first, second and third recessed areas parallel to one another. A lower surface of the first container includes first and second projecting areas that are dimensioned, shaped and oriented to align with the first and third recessed areas. The second container has an upper surface with first and second recessed areas parallel to one another and a lower surface with third and fourth projecting areas dimensioned, shaped and be oriented to aligned with the first and second recessed areas of the first container and align with the first and second recessed areas of the second container when stacked vertically.
