Solution Overview

Problem

Traditional modular building systems face challenges in ease of assembly, requiring skilled labor, material wastage, and durability, with existing lock mechanisms failing to provide a strong and rigid connection without deformation or wear.

Innovation Solution

A modular building system comprising structural frames with grooves and bevel surfaces, a lock mechanism with a top and bottom shell, tension screws, and corner supports, allowing for rapid assembly using a wrench holder and structural insulated panels, which connects beams and posts firmly and rigidly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional lock mechanisms are used to connect structural frames, then the building system can be assembled, but the connection is not strong and rigid enough, and the lock mechanism suffers from wear and tear

Engineering Contradiction:
Improveconnection strengthVSAvoiddurability of lock mechanism
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The lock mechanism is divided into separate components: a lock body with a channel, a beam with a groove, and a locking element. This segmentation allows each part to be optimized for its specific function while working together to create a strong, durable connection that eliminates wear and tear through a friction-based fit rather than threaded engagement.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If cutting and drilling of frames is performed during assembly, then the building system can be customized, but material wastage increases

Engineering Contradiction:
Improvecustomization capabilityVSAvoidmaterial wastage
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The structural frames are pre-cut and pre-drilled during manufacturing before shipment to the assembly site. This preliminary action allows for precise factory-controlled cutting and drilling with minimal waste, while still enabling customization. The pre-prepared frames can be directly assembled using the lock mechanism without requiring additional cutting or drilling during construction.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If traditional assembly methods are used, then building structures can be constructed, but the process requires high skill labor and longer duration

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The lock mechanism is designed to be self-aligning and self-locking. The beam with the groove fits into the lock body's channel, and the locking element automatically secures the connection when properly positioned. This self-service design eliminates the need for complex alignment procedures or specialized tools, allowing assembly to be performed quickly by workers with minimal training, thereby dramatically increasing assembly speed and productivity.

Inventive Principle:
Principle #25Self-service
