Stackable Storage Bin Angled Slot Interlock Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable storage bins lack secure interlocking mechanisms when vertically stacked and do not allow for transparent observation of contents, especially when a lid is present.
Innovation Solution
A stackable storage bin design featuring angled tabs and slots for interlocking with other bins, combined with transparent and translucent sections for content visibility, and a removable pivotable lid, along with optional divider walls and hanging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional stackable storage bins are designed with solid walls for durability and privacy, then structural strength is improved, but the ability to observe contents from the outside deteriorates
Solution Approach 1:
The storage bin incorporates different material properties in different locations: the rear wall and lower portions of side walls are made opaque for structural strength and privacy, while the front wall and upper portions are made transparent to allow visibility of contents. This local differentiation of material quality resolves the contradiction between strength and visibility.
2Ease of manufacture
If stackable storage bins are designed without interlocking mechanisms for simplicity of manufacture, then manufacturing complexity is reduced, but the security and stability of vertical stacking deteriorates
Solution Approach 1:
The interlocking mechanism merges the rim structure of one bin with the base structure of the bin below it through complementary grooves and protrusions. The rim of the upper bin fits into the base of the lower bin, creating a unified stacked structure that provides secure stacking while maintaining manufacturing simplicity through integrated design.
3Stability of the object's composition
If storage bins are designed with fixed lids for structural integrity, then structural stability is improved, but the ease of access and removal of contents deteriorates
Solution Approach 1:
The lid is designed with hinge connections that allow it to pivot between a closed position (maintaining structural stability and security) and an open position (providing easy access to contents). This dynamic capability resolves the contradiction between structural stability and operational ease by allowing the lid to adapt its state based on usage requirements.
4Loss of information
If transparent materials are used throughout the storage bin for maximum visibility, then visibility of contents is improved, but structural strength and privacy protection deteriorates
Solution Approach 1:
The storage bin incorporates different material properties in different locations: the rear wall and lower portions of side walls are made opaque for structural strength and privacy, while the front wall and upper portions are made transparent to allow visibility of contents. This local differentiation of material quality resolves the contradiction between strength and visibility.

AI summary
A stackable storage bin includes a body having a rim extending around an open top. A first angled slot is formed in an upper edge of each side wall adjacent a rear end thereof and a vertical second slot is formed in the upper edge of each side wall at a position forwardly from the first slot. An angled first tab is formed adjacent the bottom edge of each side wall in a position vertically aligned with the first slot and a vertical second tab is formed adjacent a bottom edge of each side wall at a position vertically aligned with the vertical second slot whereby when two of the bins are in the vertically stacked array, the tabs on the bottom of an upper bin engage the slots on the lower bin to interlock the two bins together.
