Solution Overview

Problem

Existing collapsible and reusable containers lack the ability to provide watertightness and are not designed for transporting liquids or dry cargo efficiently, especially in remote regions without sophisticated utilities.

Innovation Solution

The development of waterproof, collapsible, and reusable containers with self-sealing reciprocating channel edge fasteners, which can be constructed from molded plastic panels or corrugated plastic panels with integral fittings, allowing for easy assembly and disassembly without the need for tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional containers are used, then they can transport cargo, but they lack watertightness and cannot efficiently transport liquids

Engineering Contradiction:

ImprovewatertightnessVSAvoidtransport capability for liquids and dry cargo

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The container is divided into multiple panels that can be assembled together to form a complete structure. Each panel can be independently manufactured and then joined using self-sealing fasteners to create a watertight seal, allowing the container to effectively transport both liquids and dry cargo.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple functions into a single container system: it integrates watertight sealing capability, collapsible structure for space efficiency, and universal transport applicability for both liquids and dry goods, replacing the need for separate specialized containers.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If containers are made durable and watertight, then they can transport liquids, but they become more complex and harder to assemble

Engineering Contradiction:

ImprovewatertightnessVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The container employs self-sealing reciprocating channel edge fasteners that automatically create watertight seals when panels are joined. The fasteners self-adjust and self-seal without requiring additional sealing components or complex assembly procedures, maintaining simplicity while achieving reliable watertightness.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The fastener design creates an equipotential sealing interface where the reciprocating channels align perfectly between adjacent panels, ensuring uniform water-tight contact across the entire joint without requiring precision adjustment or complex alignment mechanisms.

Inventive Principle:

Principle #12Equipotentiality

3Power

If traditional loading methods are used with heavy machinery, then cargo can be loaded onto raised platforms, but it requires heavy machinery and is costly

Engineering Contradiction:

Improveloading capabilityVSAvoidmachinery requirement

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent replaces heavy mechanical loading systems (forklifts, cranes, pumpjacks) with a winch mechanism that uses cable and drum technology to pull carts onto raised platforms. This substitution dramatically reduces equipment weight, complexity, and cost while maintaining adequate loading power for the application.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The winch system introduces a cable as an intermediary element between the power source and the cargo carts. This allows force to be transmitted efficiently over distance and around obstacles, enabling loading onto raised platforms without direct mechanical contact or heavy equipment underneath the platform.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Volume of moving object

If collapsible containers are used, then they save space when empty, but they may compromise structural strength and durability

Engineering Contradiction:

Improvestorage space when collapsedVSAvoidstructural strength

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The container is designed with dynamic structural properties that allow it to transition between collapsed and expanded states. When expanded and properly assembled with the fasteners, the structure achieves full structural strength equivalent to rigid containers, while maintaining the space-saving collapsed configuration for storage and transport.

Inventive Principle:

Principle #15Dynamics

AI summary

Collapsible reusable watertight carrying push/pull carts are assembled or 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. A winch is provided inside the cargo area of a transport vehicle for loading each push/pull cart onto a raised platform in the vehicle. The winch is preferably mounted on a forward portion of the platform with a cable extending rearwardly from each winch terminating with a cable hook removably engaging joined carts whereby said the joined carts are moved onto the platform without use of weighty storage transport pallets and without the need of heavy machinery to move a cargo of said carts onto said platform.
