Collapsible Container Bottom Plate Groove Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing collapsible containers face a challenge in maintaining the strength of the bottom plate while accommodating grooves for support rails and preventing misalignment during stacking, which can lead to warpage or deformation.
Innovation Solution
The collapsible container design includes a bottom plate with specific grooves - a first groove along the outer edge, second grooves parallel to the short sides, and third grooves parallel to the long sides - allowing for support rail fitting without compromising the bottom plate's strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If grooves for support rails are formed in the installation surface of the bottom plate, then the collapsible container can be conveyed along support rails automatically, but the installation surface area is decreased and the bottom plate thickness is reduced, leading to warpage or deformation
Solution Approach 1:
The groove system is segmented into three distinct types: first grooves along the outer circumferential edge for positioning protrusions, second grooves parallel to short sides for additional positioning, and third grooves parallel to long sides for support rail fitting. This segmentation allows each groove type to serve its specific function while minimizing the overall impact on bottom plate strength.
Solution Approach 2:
The groove depths are differentiated by function: the first and second grooves have greater depth for positioning stability, while the third grooves have smaller depth specifically for support rail accommodation. This local quality variation ensures that grooves provide necessary functionality while preserving bottom plate strength in critical areas.
2Stability of the object's composition
If grooves are formed in the installation surface for preventing misalignment of stacked containers, then stacking alignment is improved, but the bottom plate structure is weakened
Solution Approach 1:
The positioning groove system is divided into first grooves along the outer edge and second grooves parallel to the short sides, creating a coordinated groove network that provides comprehensive positioning coverage without requiring deep grooves across the entire bottom plate surface.
Solution Approach 2:
The first grooves positioned along the outer circumferential edge provide primary positioning for stacked containers, while the second grooves provide secondary positioning. This localized groove distribution achieves stable stacking alignment while minimizing material removal and preserving bottom plate strength.

AI summary
A collapsible container includes a lower frame, an upper frame, lateral plates, and a pair of lid plates. On the upper frame or the pair of lid plates, a plurality of positioning protrusions is provided to protrude upward along a circumferential edge of the upper frame. An installation surface of a bottom plate includes a first groove into which the positioning protrusions of a lower one of each pair of vertically adjacent collapsible containers stacked up are fitted, a second groove into which the positioning protrusions of a lower one of each pair of vertically adjacent collapsible containers stacked in a pinwheel configuration are fitted, and a plurality of third grooves that is formed parallel to long sides of the bottom plate and into which support rails are fitted. The third grooves are smaller in depth from the installation surface than the first groove and the second groove.
