Interlocking Bulk Bin Sleeve Pack Wall Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk bin sleeve packs are either permanently secured, preventing collapsibility for storage, or require cumbersome additional pieces for assembly and disassembly, making them inefficient for space-saving and deployment.
Innovation Solution
A bulk bin sleeve pack design featuring interlocking wall members with locking tabs and openings that allow for repeated erection and collapse, using a base with a perimeter wall assembly that secures the wall members together without additional pieces, enabling easy deployment and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wall members are permanently secured to one another using adhesive, then structural integrity is improved, but collapsibility for storage is lost
Solution Approach 1:
The bulk bin is divided into separate wall members that can be independently collapsed and stored. Each wall member remains structurally intact through its own rigidity while allowing the overall structure to be disassembled and collapsed for storage, resolving the contradiction between structural integrity and collapsibility.
Solution Approach 2:
The connection between wall members transitions from static permanent bonding to dynamic interlocking that allows both stable operation when erected and flexible collapse when stored. The interlocking mechanism enables the structure to adapt between rigid operational state and collapsed storage state.
2Adaptability or versatility
If wall members are held together by a separate connection assembly, then collapsibility is maintained, but device complexity increases due to additional pieces
Solution Approach 1:
The connection functionality is merged directly into the wall members through integrated interlocking features (locking tabs and locking openings) that are formed as part of the wall members themselves. This eliminates the need for separate connection assemblies while maintaining collapsibility, reducing overall device complexity.
Solution Approach 2:
The wall members are self-contained with built-in interlocking features that enable them to connect and disconnect from one another without requiring external connection pieces. The structure serves its own connection needs through integrated locking tabs and openings, simplifying the overall system.
3Ease of operation
If additional pieces are used for connection, then ease of operation is improved for assembly, but ease of manufacture deteriorates due to multiple components
Solution Approach 1:
The connection features are combined with the wall members in a single manufacturing process, eliminating the need to produce separate connection pieces. This maintains ease of operation during assembly while simplifying manufacturing by reducing the number of distinct components that need to be produced and inventory managed.

AI summary
A sleeve pack for forming a bulk bin includes a base for forming a bottom of the bulk bin and a perimeter wall assembly. The perimeter wall assembly includes two blanks that can be connected to one another at interlocking connections to form a perimeter wall of the bulk bin. Locking tabs are associated with at least one of the wall blanks, and corresponding locking openings are associated with at least one other of the wall blanks. The openings oppose the tabs and the tabs are lockingly inserted into the openings to secure the wall members together to form the perimeter wall of the bulk bin.
