Solution Overview

Problem

Existing container modules for temporary or permanent human habitation are not adequately fireproof or soundproof, and they lack durability during seismic activities due to metal components weakening under thermal stress, and they are not efficiently designed for easy handling and transportation.

Innovation Solution

A method for manufacturing a container module by forming at least four panels with a concrete core facing inward and an external metal plate facing outward, where twist-lock elements are integrated into each corner for secure handling and assembly, and the panels are welded together to create a rectangular parallelepiped structure, enhancing fire resistance and soundproofing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If metal containers are used for module construction, then ease of manufacture and transport is improved, but fire resistance and seismic durability deteriorate

Engineering Contradiction:
Improveease of manufactureVSAvoidfire resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The container module employs a composite structure combining metal external plates with concrete core panels. The metal plates provide structural strength and ease of manufacture, while the concrete core provides fire resistance and seismic durability. This composite approach resolves the contradiction by integrating materials with complementary properties.

Inventive Principle:
Principle #40Composite materials

2Reliability

If concrete is added to shipping containers for fireproofing, then fire resistance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvefire resistanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The container is divided into modular panels, each consisting of an external metal plate and a concrete core. These standardized panels can be manufactured independently and then assembled, reducing overall manufacturing complexity compared to monolithic concrete container construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The concrete cores and metal plates are prepared as separate pre-manufactured components before final assembly. This preliminary preparation allows for optimized manufacturing processes for each material type and simplifies the final assembly process.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If twist-lock elements are added to corners for secure handling, then handling reliability is improved, but device complexity increases

Engineering Contradiction:
Improvehandling reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The twist-lock elements are integrated directly into the corner structures of the container panels during manufacturing. This merging of the locking mechanism with the structural corners eliminates the need for separate attachment processes and reduces overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
