Structure of storage box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage boxes lack a stable temporary orientation limitation mechanism for their front cover, and when stacked, they tend to tilt forward when the front cover is opened for item insertion or removal, which compromises convenience and stability.
Innovation Solution
A storage box design featuring a pivotally connected front cover that snap-fits with the upper cover to form a stacking assembly, utilizing a convex portion on the upper cover to prevent tilting by engaging with a concave portion on the main body, ensuring stable temporary orientation and enhanced stacking stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front cover is pivotally connected to allow opening for item insertion/removal, then ease of operation is improved, but stability deteriorates because the box tilts forward when the cover is opened
Solution Approach 1:
The patent applies preliminary anti-action by providing a support structure that counteracts the forward tilting force before it can cause instability. The support member engages with the front cover and main body to provide a counterbalancing force or mechanical constraint that prevents the box from tilting forward when the cover is opened for item insertion or removal.
2Ease of operation
If the front cover is designed to be easily removable for access, then ease of operation is improved, but reliability deteriorates due to lack of stable temporary limitation
Solution Approach 1:
The patent applies dynamics by creating a temporary limitation mechanism that adapts to the operational state. The support structure can engage or disengage based on whether the front cover is open or closed, providing stable temporary limitation when needed while maintaining ease of operation when the cover is removed or opened for access.
3Ease of manufacture
If storage boxes are designed for easy stacking, then ease of manufacture and storage are improved, but stability deteriorates when upper boxes tilt forward during item insertion
Solution Approach 1:
The patent applies segmentation by dividing the stabilization function into separate components: a support member on the upper storage box and a corresponding engagement structure on the lower box. This segmentation allows the stacking mechanism to remain simple and easy to manufacture while providing reliable stability prevention against forward tilting during item insertion or removal.

AI summary
A structure of a storage box includes a main body, a stacking assembly, and a forward opening. The main body has an upper and front-facing opening and a recess on the rear. The stacking assembly is attached to the main body, covers the upper and front-facing opening, and has an upper cover and a front cover, the upper cover fitted to the front cover with a snap and having a convex portion, the shape of the convex portion identical to the shape of the recess. The forward opening is a part of the upper and front-facing opening of the main body and is covered by the front cover. When two or more storage boxes are stacked, the convex portion of the second storage box embeds the recess of the first storage box, preventing the entire structure from tilting forward when the front cover of the storage box above is opened.
