Solution Overview

Problem

Existing shipping container stacking systems limit the conversion of multiple containers into multi-story living spaces due to direct contact and lack of space for utilities and access, prohibiting the integration of residential or commercial infrastructure.

Innovation Solution

A corner support brace and stacking frame system that provides spacing and structural support between stacked containers, enabling the distribution of utilities and access features like balconies and stairways, allowing for multi-story apartment buildings with integrated services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If containers are stacked directly on top of each other to maximize space utilization, then storage density is improved, but space for utilities and access is eliminated

Engineering Contradiction:
Improvestorage densityVSAvoidaccess for utilities
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The corner post is segmented into multiple components: base plate, mid-plates, and cap plate that can be assembled separately and then connected. This segmentation allows the corner post to provide both structural support and integrated utility access points without requiring direct container contact, resolving the contradiction between dense stacking and utility access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The corner post acts as an intermediary element between stacked containers, providing spacing and structural support while incorporating utility access features. This mediator enables both dense stacking and utility access by decoupling the direct contact requirement from the stacking function.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If containers are stacked with spacing to allow utility access and residential infrastructure, then ease of operation is improved, but storage density deteriorates

Engineering Contradiction:
Improveaccess for utilitiesVSAvoidstorage density
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The corner post serves multiple functions simultaneously: structural support, spacing maintenance, utility access provision, and stacking enablement. This multi-functionality allows spacing for utilities without sacrificing storage density, as the same component that provides spacing also enables dense stacking through its structural role.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If corner posts are removed to enable non-standard stacking configurations, then adaptability is improved, but structural strength deteriorates

Engineering Contradiction:
Improvestacking configurationsVSAvoidcorner support
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The corner post system is designed to be adaptable to different stacking configurations while maintaining structural integrity. The modular design with base plates, mid-plates, and cap plates allows flexibility in arrangement while each component maintains its load-bearing function, enabling both adaptability and strength.

Inventive Principle:
Principle #15Dynamics

4Productivity

If multiple containers are converted into multi-story living spaces, then housing productivity is improved, but manufacturing complexity deteriorates

Engineering Contradiction:
Improvehousing construction efficiencyVSAvoidstacking system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The corner posts are pre-assembled with base plates, mid-plates, and cap plates before deployment. This preliminary assembly simplifies the on-site construction process, enabling rapid stacking of containers into multi-story configurations without complex on-site assembly procedures, thus improving productivity while managing manufacturing complexity.

Inventive Principle:
Principle #10Preliminary action
