Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing soft containers for bulk cargo transportation and storage are inconvenient and unreliable due to their complex two-part design, inadequate load distribution, and susceptibility to damage, particularly during transportation and discharging of multi-tonnage cargoes.

Innovation Solution

The container incorporates a soft sling ring for load distribution, reinforced transverse tapes forming an octagonal bottom, and a detachable protective jacket with a collar connection system to enhance stability and protection, replacing sewn tapes with heat-sealed detachable clasps and providing a robust transverse system for the sling structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the container uses a two-part design with detachable joint, then ease of assembly is improved, but reliability of cargo discharge is worsened due to potential displacement of the discharge valve

Engineering Contradiction:

Improveease of assemblyVSAvoidreliability of cargo discharge

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The container is divided into two main parts: a bearing framework in the form of a net and an internal insert (vessel). These parts are connected through a detachable joint system using loops and tie-up strings, allowing for easier assembly and disassembly while maintaining structural integrity during cargo discharge.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A bearing net acts as an intermediary element between the vessel and the lifting/transportation system. The net provides a stable base that secures the vessel and maintains the correct position of the discharge valve, preventing displacement during handling and transportation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If sewn tapes are used to attach transverse rings, then ease of manufacture is improved, but reliability is worsened due to potential tape tearing and material hole formation

Engineering Contradiction:

Improveease of attachmentVSAvoidintegrity of attachment

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The traditional mechanical sewing method is replaced with a heat-sealing process. The collar connection system uses heat-sealed detachable clasps that attach transverse rings to the protective tunnel without puncturing the material, thereby maintaining material integrity and preventing tape tearing while still providing easy attachment and detachment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the bottom is formed by simple intersection of sling tapes, then device complexity is reduced, but strength is insufficient to withstand multi-tonnage cargo

Engineering Contradiction:

Improvesimplicity of bottom structureVSAvoidstrength of bottom

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The bottom structure combines multiple elements: sling tapes intersecting to form a grid, reinforced transverse tapes providing additional structural support, and heat-sealed detachable clasps creating rigid connection points. This composite structure maintains relative simplicity while significantly enhancing the load-bearing capacity to withstand multi-tonnage cargo.

Inventive Principle:

Principle #40Composite materials

4Ease of manufacture

If transverse rings are located outside without protection, then ease of manufacture is improved, but susceptibility to damage increases during transportation

Engineering Contradiction:

Improveease of positioningVSAvoidsusceptibility to damage

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

A protective jacket is provided that covers and protects the transverse rings and other vulnerable components before they are subjected to damaging forces during transportation and handling. This pre-protective measure prevents damage without complicating the positioning or assembly process.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
