Collapsible Containers With Self-Sealing Channel Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible and reusable containers lack watertightness and versatility in sizes, making them unsuitable for transporting liquids or dry cargo, especially in remote regions without sophisticated supply utilities, and require heavy machinery for unloading cargo.
Innovation Solution
Development of collapsible, foldable, and reusable containers with self-sealing reciprocating channel edge fasteners made from molded or corrugated plastic panels, featuring U-shaped or J-shaped channels for watertight connections, which can be assembled and disassembled without tools, and include a push/pull cart with a fail-safe braking system for easy maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collapsible containers are made from molded plastic panels with traditional connectors, then assembly and disassembly become easier, but watertightness is compromised
Solution Approach 1:
The container is divided into modular panels that can be independently assembled and disassembled. Each panel connects through segmented connector elements (nibs and receiving structures) that allow tool-free assembly while maintaining watertight seals through the modular design.
Solution Approach 2:
Connector elements act as intermediaries between panels, featuring nibs that engage with receiving structures. These intermediaries transfer both mechanical load and sealing function, enabling easy assembly while ensuring watertight connections through the intermediary sealing mechanism.
2Strength
If containers are made rigid and non-collapsible, then structural strength is improved, but storage efficiency and transport convenience deteriorate
Solution Approach 1:
The container transitions from a rigid static structure to a dynamic collapsible structure. Panels can be folded along hinge lines and connected/disconnected through engageable structures, allowing the container to adapt its volume from fully assembled (high strength) to collapsed (compact storage) states.
Solution Approach 2:
When collapsed, the container panels nest within each other in a compact configuration. The side panels, bottom panel, and cover can be folded and stacked, creating a nested structure that minimizes storage volume while maintaining structural integrity when assembled.
3Device complexity
If traditional latches and hinges are used for assembly, then device complexity is reduced, but watertightness and sealing capability worsen
Solution Approach 1:
The connector element merges multiple functions into a single integrated structure. The nib simultaneously provides mechanical engagement (latch function) and sealing (gasket function), eliminating the need for separate latches and hinges while ensuring watertight connections through the combined mechanism.
4Quantity of substance
If heavy machinery and pallets are used for cargo transport, then loading capacity is improved, but operational cost and environmental impact worsen
Solution Approach 1:
The container serves multiple functions: it acts as both the cargo holding structure and its own transport platform when equipped with wheeled assemblies. This eliminates the need for separate pallets and heavy machinery, reducing operational costs and environmental impact while maintaining adequate loading capacity for various cargo types.

AI summary
Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or in disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.
