Solution Overview

Problem

There is a need for construction designs that utilize inexpensive and readily available materials while simplifying the fabrication, construction, and assembly of portable structures, such as pre-fabricated houses, which can be easily transported and assembled at a site.

Innovation Solution

The use of pre-fabricated houses comprising metal and cement-based components, including steel pillars, concrete wall panels with metal attachments, and beams with mating components for easy coupling through welding or bolting, allowing for efficient assembly and structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pre-fabricated components with metal attachments are used, then assembly speed and structural integrity are improved, but manufacturing complexity increases

Engineering Contradiction:

Improveassembly speedVSAvoidmanufacturing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Metal attachments are pre-installed on wall panels and beams during manufacturing, so that when components are assembled on-site, the connections are already prepared and ready for rapid assembly without requiring complex field fabrication work

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The structure is divided into modular pre-fabricated components (wall panels, beams, pillars) that can be manufactured separately and assembled quickly on-site, improving productivity while managing complexity through standardization

Inventive Principle:

Principle #1Segmentation

2Strength

If metal and cement-based materials are used, then structural integrity is improved, but cost increases

Engineering Contradiction:

Improvestructural integrityVSAvoidcost

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The structure uses composite construction combining cement-based wall panels with metal attachments and steel beams, leveraging the compressive strength of cement and the tensile strength of metal to achieve high structural integrity while optimizing material costs through appropriate material selection for each component

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

Metal attachments are strategically placed only at connection points where strength is most needed, rather than using metal throughout the entire structure, thereby achieving high structural integrity at connection-critical locations while minimizing overall material cost

Inventive Principle:

Principle #3Local quality

3Loss of time

If pre-fabricated components are used, then construction time is reduced, but transportation and logistics complexity increases

Engineering Contradiction:

Improveconstruction timeVSAvoidlogistics complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The structure is segmented into standardized modular components of manageable sizes that can be efficiently transported using conventional logistics infrastructure, reducing construction time while keeping transportation logistics simple and practical

Inventive Principle:

Principle #1Segmentation
