Solution Overview

Problem

Existing protection systems for roll containers are cumbersome, time-consuming to install, generate waste, and fail to adequately protect goods from falling, theft, and environmental exposure, while being inefficient in space usage and adaptability.

Innovation Solution

A flexible, detachable protection system for roll containers using fastening means, made of lightweight materials, that can be easily installed and stored, providing comprehensive protection against falling, theft, and environmental factors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive film is used to wrap the roll container, then goods are effectively prevented from falling and theft is prevented, but application is time-consuming and the film cannot be reused generating waste

Engineering Contradiction:

Improveprotection effectivenessVSAvoidapplication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent uses a flexible net made of plastic material that can be easily wrapped around the roll container and adjusted to fit different sizes. The net replaces the adhesive film while maintaining protection functionality, allowing for quick installation and removal without waste generation issues

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If a grid or net protection system is installed, then goods are protected from falling and theft, but the system is heavy and unwieldy making return transport and storage difficult

Engineering Contradiction:

Improveprotection effectivenessVSAvoidprotection system weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent employs a flexible net made of lightweight plastic material instead of heavy rigid grids. The net can be easily manipulated, transported, and stored, significantly reducing the weight and handling difficulty while maintaining effective protection against falling and theft

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a net or grid protection system is used, then protection against falling and theft is provided, but goods remain exposed to the elements and other contaminants

Engineering Contradiction:

Improveprotection against falling and theftVSAvoidexposure to elements

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The flexible net can be combined with a cover made of weather-resistant material to create a complete enclosure. This combination provides both mechanical protection against falling and theft while simultaneously shielding goods from environmental factors like rain, wind, and sun

Inventive Principle:

Principle #30Flexible shells and thin films

4Object-affected harmful factors

If plastic fabric or rigid film protection system is placed over the roll container, then protection against the elements is provided, but the system does not prevent goods from falling and installation is complex

Engineering Contradiction:

Improveprotection against elementsVSAvoidprevention of falling

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent uses a flexible net that is specifically designed to conform to the roll container shape and secure goods through its mesh structure. The net can be combined with a cover to provide both element protection and falling prevention, with simple installation that does not require complex positioning

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The protection system is divided into separate components: the net that prevents falling and the cover that protects against elements. This segmentation allows each component to perform its specific function effectively while simplifying installation and adjustment

Inventive Principle:

Principle #1Segmentation

5Weight of moving object

If boards or panels are attached to the grids using drawstrings, then the system is lighter than grids, but they take up a lot of space complicating return transport and storage

Engineering Contradiction:

Improveprotection system weightVSAvoidstorage space

Core Design Contradiction:

Weight of moving objectVSVolume of moving object

Solution Approach 1:

The flexible net and cover can be folded or rolled into a compact form when not in use, significantly reducing the storage volume compared to rigid boards or panels. The lightweight plastic material maintains low weight while enabling compact storage configuration

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

The invention relates to a protection system (100) for protecting goods (290) to be transported on a roll container (200). The protection system (100) comprises at least one lateral wall (111, 112), and the roll container (200) comprises at least one lateral surface (211, 212, 213), said at least one lateral wall (111, 112) partly or completely covering the at least one lateral surface (211, 212, 213). The protection system (100) comprises at least one securing means (121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136), and the protection system (100) can be releasably or permanently connected to the roll container (200) via the at least one securing means (121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136). The protection system (100) is made of a flexible material.
