Collapsible Container Stacking Member Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible containers face issues with stacking and handling due to inadequate stacking rails and accidental detachment of stacking bars, which complicates operations like folding and washing.
Innovation Solution
Incorporation of a locking element, such as a snap-fit securing means, on the stacking members to secure them to the container, preventing unwanted detachment and facilitating easier handling and folding, while allowing for easy detachment and replacement if damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If stacking members are made detachable for easy replacement, then ease of repair is improved, but reliability deteriorates due to accidental detachment during handling
Solution Approach 1:
The locking element is designed as a separate replaceable component integrated with the stacking member, allowing the stacking member to be divided into replaceable segments. This enables easy replacement of damaged stacking members while maintaining secure attachment through the locking element mechanism.
Solution Approach 2:
The locking element provides localized securing functionality at specific points on the stacking member. By concentrating the locking function in discrete locations rather than distributing it throughout the entire structure, the design achieves both secure attachment and easy replaceability of individual components.
2Ease of operation
If stacking rails are extended inboard for easier stacking, then ease of operation is improved, but device complexity worsens due to additional structural requirements
Solution Approach 1:
The stacking member serves multiple functions: it acts as both the stacking rail that supports nested containers and as a structural component integrated with the container walls. This multi-functionality eliminates the need for separate stacking rails, achieving easy stacking operations without increasing structural complexity.
Solution Approach 2:
The stacking member is merged with the container wall structure, combining what would traditionally be separate components (container walls and stacking rails) into a single integrated element. This reduces overall device complexity while maintaining ease of stacking operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The locking element enhances the stability and longevity of the container by preventing accidental detachment during handling and folding, improving operational efficiency and reducing maintenance costs by allowing for separate replacement of the stacking members.

AI summary
The present invention relates to a collapsible container (10) comprising a base (12), a first pair of opposed walls (14) and a second pair of opposed walls (16), the first pair of opposed walls and the second pair of opposed walls defining an opening in the top of the container, wherein the container further comprises at least one stacking member (18) which, when the container is erect, is movable between a stacking position in which the stacking member is positioned to support the base of another container thereon and a filling position in which the stacking member is substantially removed from the opening in the top of the container, and wherein the container further comprises at least one locking element (20) for securing the at least one stacking member to the container.
