Stackable Container with 90-Degree Rotation for Interior Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable and nestable containers do not allow access to the interior space when in a stacked position, requiring exact alignment of sidewalls and often necessitating additional hardware for stacking, which limits their utility in space-saving and accessibility.
Innovation Solution
A container design featuring a bottom, open top, and sidewalls with curved structures and channels that enable stacking by a 90-degree rotation, allowing access to the interior space from either end while maintaining secure engagement through molded channels and handles, eliminating the need for extra parts or hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If containers are stacked vertically to save space, then floor space utilization is improved, but access to the interior space of stacked containers becomes difficult or impossible
Solution Approach 1:
The container is divided into four distinct openings (first opening in first sidewall, second opening in second sidewall, third opening in third sidewall, fourth opening in fourth sidewall), allowing access to the interior space from multiple directions. This segmentation enables users to access containers in a stack from side, end, or top depending on which opening is most accessible, resolving the contradiction between vertical stacking and interior access.
Solution Approach 2:
The invention transitions from traditional top-only access (single dimension) to multi-directional access by incorporating openings in all four sidewalls. This dimensional expansion allows users to access the interior space horizontally from any side of the container, even when stacked vertically, thereby maintaining ease of operation while achieving space-saving vertical stacking.
2Area of stationary object
If containers are designed to be nestable for space saving, then storage efficiency is improved, but the open-top design limits stacking flexibility and accessibility
Solution Approach 1:
The container is designed with universal functionality to perform both nesting and stacking operations. The combination of open top, four sidewall openings, and specifically positioned curved structures enables the container to be nested within another container for maximum space saving, or stacked vertically with containers oriented at 90-degree angles for improved accessibility, providing versatile adaptability to different storage needs.
Solution Approach 2:
The container design allows dynamic adaptation between different stacking configurations. Users can choose to nest containers for maximum compactness or stack them with 90-degree orientation for improved access, depending on the immediate storage needs and space constraints. This dynamic flexibility resolves the contradiction between storage efficiency and stacking versatility.
3Stability of the object's composition
If additional hardware is added to enable stacking, then stacking stability is improved, but device complexity and cost increase
Solution Approach 1:
The stacking functionality is merged into the existing container structure through the curved structures that are already part of the sidewalls. The curved structures serve dual purposes: maintaining container shape and providing stacking engagement surfaces. This integration eliminates the need for separate stacking hardware, achieving stacking stability without increasing device complexity or part count.
Solution Approach 2:
The container's own curved structures and geometric features provide the stacking mechanism, making the container self-sufficient for stacking without requiring external hardware. The curved structures naturally engage with corresponding features on stacked containers, and the open-top design with four openings allows the container to stabilize itself in various stacking orientations, eliminating dependency on additional parts.

AI summary
A container capable of being placed in a stacking configuration with an identical second container includes a bottom, a top rim defining an open top, and a sidewall contiguous with and extending between the bottom and the top rim to define an inner space. The container further includes a first curved structure forming at least part of the top rim adjacent a first sidewall side and a second curved structure forming at least part of the top rim adjacent a second sidewall side and disposed opposite the first curved structure. The container also includes first and second channels molded into the bottom and at least partially protruding into the inner space, the channels being substantially parallel to each other and to first and second sidewall ends, wherein a distance between the first and second channels is substantially equal to a first distance between the first and second curved structures.
