Solution Overview

Problem

Modular building construction faces challenges such as transportation difficulties, on-site assembly requirements, and customization limitations, which hinder its widespread adoption despite potential cost efficiencies.

Innovation Solution

A modular building system comprising rods, u-shaped channel pieces, and panels that form a frame, allowing for off-site assembly of rectangular box frames with corrugated metal panels and insulation, which can be easily transported and assembled on-site using corner castings and twist locks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If modular building sections are produced separately in a manufacturing facility, then manufacturing cost and efficiency are improved, but transportation difficulty increases

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidtransportation difficulty
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The building is divided into multiple modular sections that can be manufactured separately and then assembled on-site. Each module is designed as a self-contained unit with standardized dimensions and connection interfaces, enabling independent production while maintaining overall structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Standardized connection mechanisms and universal interface designs are implemented across all modular sections. The corner castings and connection elements are designed to work with multiple module types, allowing the same connection system to serve various building configurations and reducing transportation complexity.

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

2Productivity

If modular building sections are produced separately in a manufacturing facility, then manufacturing cost and efficiency are improved, but on-site assembly complexity increases

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidon-site assembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The building is divided into multiple modular sections that can be manufactured separately and then assembled on-site. Each module is designed as a self-contained unit with standardized dimensions and connection interfaces, enabling independent production while maintaining overall structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular sections are designed with self-aligning features and intuitive connection mechanisms that reduce the need for specialized equipment and expertise during assembly. The corner castings and connection elements are designed to automatically guide proper positioning, allowing workers to assemble modules with minimal training and equipment.

Inventive Principle:
Principle #25Self-service

3Productivity

If modular building sections are produced separately in a manufacturing facility, then manufacturing cost and efficiency are improved, but modification difficulty increases

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidmodification difficulty
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The building is divided into multiple modular sections that can be manufactured separately and then assembled on-site. Each module is designed as a self-contained unit with standardized dimensions and connection interfaces, enabling independent production while maintaining overall structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection system is designed to be dynamic and adjustable rather than fixed. The corner castings and connection elements allow for reconfiguration and modification of the building structure after assembly, enabling clients to request changes and expansions without requiring complete demolition or complex structural modifications.

Inventive Principle:
Principle #15Dynamics

4Productivity

If modular building sections are produced separately in a manufacturing facility, then manufacturing cost and efficiency are improved, but assembly equipment requirements increase

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidassembly equipment requirements
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The modular sections are designed with self-aligning features and intuitive connection mechanisms that reduce the need for specialized equipment and expertise during assembly. The corner castings and connection elements are designed to automatically guide proper positioning, allowing workers to assemble modules with minimal training and equipment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The most complex assembly functions are extracted and integrated directly into the modular sections themselves during manufacturing. Connection elements, alignment features, and securing mechanisms are pre-installed on each module, eliminating the need for specialized assembly equipment at the construction site.

Inventive Principle:
Principle #2Taking out (Extraction)
