Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing training rig systems for ISO shipping containers are inflexible, costly, and limited in functionality due to the need for specially designed containers, which restricts the use of the container and requires extensive assembly facilities, and suffer from corrosion and limited height for exercises.

Innovation Solution

A modular attachment system that attaches to the upper edge of ISO shipping containers using inside and outside corner brackets with fastening means, allowing for robust and flexible attachment of training rigs without modifying the container, enabling full height and length utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If brackets are mounted on the container walls to attach the training rig, then the rig can be attached to the container, but the container walls must be modified with holes and screws which limits container flexibility and causes corrosion

Engineering Contradiction:

Improveattachment reliabilityVSAvoidcontainer flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The attachment system extracts the mounting function from the container walls themselves and relocates it to dedicated attachment means (corner brackets and beam attachments) that connect to the container's frame. This removes the need to modify the container walls with holes and screws, preserving container flexibility while providing reliable attachment points through the frame structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The attachment means acts as an intermediary between the training rig and the container. Instead of directly attaching the rig to the container walls (which causes corrosion and limits flexibility), the attachment means with its receiving parts and connection to the frame provides a mediating interface that solves both the reliability and flexibility requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the training rig is attached to the corrugated walls below the frame, then the rig can be secured to the container, but the available height for exercises is limited

Engineering Contradiction:

Improverig securementVSAvoidavailable height

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The attachment system transitions from attaching to the vertical wall surface (below the frame) to attaching to the horizontal frame structure at the top edge of the container. This dimensional change in attachment location maximizes the vertical space available for exercise equipment and user movement while maintaining secure attachment through the frame's corner fittings.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If specially designed containers with brackets and interior racks are used, then the training rig can be attached, but the cost increases and assembly facilities are required

Engineering Contradiction:

Improveattachment integrationVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The attachment means is designed to be universally compatible with standard ISO shipping containers by utilizing their standardized frame and corner fittings. This eliminates the need for specially designed containers with pre-installed brackets and interior racks, reducing manufacturing complexity and assembly requirements while maintaining reliable attachment integration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system utilizes the container's own existing frame structure and corner fittings as the attachment points, making the container itself serve the attachment function. This self-service approach eliminates the need for additional specially designed container features, reducing both manufacturing cost and assembly complexity.

Inventive Principle:

Principle #25Self-service

4Reliability

If multiple holes are provided in the container walls for bolts, then the rig can be attached, but corrosion problems occur due to lack of galvanization

Engineering Contradiction:

Improveattachment strengthVSAvoidcorrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The attachment system extracts the fastening function from the container walls and relocates it to the frame structure. By using the frame and corner fittings as attachment points instead of drilling holes in the walls, the system eliminates the corrosion risk associated with wall penetrations while maintaining attachment strength through the more robust frame structure.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A first and second attachment system for attachment of a training rig to an upper edge of an ISO shipping container. Both systems include inside corner brackets that fit inside corner fittings of the container. The first attachment system further includes first attachment means with outside corner brackets which are to be attached to the inside corner brackets, second attachment means for attachment to a frame of the container and longitudinal beams for arrangement between the first and second attachment means or two second attachment means. The second attachment system includes a beam with vertical end plates and two outside corner brackets, wherein the end plates and the two outside corner brackets are to be attached to the inside corner brackets. These systems are attachable to any standard ISO shipping container and do not affect the container at all which means that no specially designed container must be used.
