Solution Overview

Problem

Existing transport containers with bracing structures face issues with deformation and instability when filled with viscous or liquid substances, particularly during lifting and stacking, due to uneven force distribution and mass displacement, which complicates handling and storage.

Innovation Solution

A transport container design featuring a jacket made of round fabric with stabilizing elements and a bracing structure that includes tensile and pressure-resistant flat struts and an adapter for forklift forks, allowing for better force distribution and secure lifting with minimal deformation, using short lifting slings and a specific bracing construction that forms a square profile for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional transport slings are attached to the casing for lifting, then the container can be lifted during transport, but deformation of the containers occurs especially when filled with liquid or free-flowing goods

Engineering Contradiction:
Improvelifting capabilityVSAvoidcontainer deformation
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The lifting function is segmented from the stabilizing function. Eight separate lifting loops are provided instead of using the stabilizing elements for lifting, allowing independent optimization of both functions without mutual interference

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Lifting loops act as intermediary elements between the lifting slings and the container body, distributing lifting forces evenly across the container structure and preventing direct stress concentration that causes deformation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If four transport slings are attached to the casing for lifting, then the container can be handled, but the high mass of the filling leads to permanent deformation or damage to the bracing structure

Engineering Contradiction:
Improvehandling capabilityVSAvoidbracing structure integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The lifting function is segmented from the stabilizing function. Eight separate lifting loops are provided instead of using the stabilizing elements for lifting, allowing independent optimization of both functions without mutual interference

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using the minimum four lifting points, eight lifting loops are provided, creating excessive lifting capacity that distributes forces more evenly and prevents overload of any single bracing element

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If multiple shipping containers are stacked one on top of the other, then storage space is optimized, but the existing balance of forces is disturbed leading to deformation or damage

Engineering Contradiction:
Improvestacking efficiencyVSAvoidbracing structure integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The stabilizing elements are segmented into four separate vertical elements that independently support stacking loads, distributing the weight of stacked containers evenly without concentrating forces on the bracing structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stabilizing elements act as intermediary load-bearing components between stacked containers and the ground, transferring stacking forces away from the bracing structure and preventing deformation

Inventive Principle:
Principle #24Intermediary (Mediator)
