Solution Overview

Problem

Traditional 'stick-built' structural steel systems require significant site time and increased transport costs due to large individual steel members, necessitating a modular structure that reduces transport size and volume while maintaining minimal site erection time.

Innovation Solution

A structural connector featuring a spigot and socket configuration with tapered portions, allowing for efficient connection and self-centering of structural members, utilizing metal additive manufacturing for precise tolerances and high-strength materials like stainless steel or titanium, enabling reduced transport volume and rapid assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional stick-built structural steel systems are used, then individual steel members can be easily fabricated and connected, but site erection time increases and transport costs increase due to large individual members

Engineering Contradiction:
Improveease of fabricationVSAvoidsite erection time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The structural system is divided into modular components (nodes and members) that can be pre-assembled into compact units. These modules are designed to be transportable in smaller volumes while maintaining structural integrity, thus reducing transport costs and enabling faster on-site assembly compared to traditional stick-built methods

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spigot is designed with a tapered configuration that nests into a corresponding tapered socket at the node. This nesting mechanism allows members to be inserted and secured within the modular node structure, enabling rapid connection without extensive on-site fabrication or alignment work, thereby reducing site erection time

Inventive Principle:
Principle #7Nested doll (Nesting)

2Loss of time

If large pre-fabricated structures are transported, then site time is minimized, but transport costs and logistics increase

Engineering Contradiction:
Improvesite timeVSAvoidtransport volume
Core Design Contradiction:
Loss of timeVSVolume of moving object

Solution Approach 1:

The structure is segmented into modular nodes and members that can be compactly packaged for transport. This segmentation allows the structure to be broken down into smaller, more transportable units that occupy less volume during transit, while still enabling rapid on-site assembly through the tapered spigot-socket connection system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tapered spigot-socket connection mechanism enables three-dimensional assembly of modular components. This dimensional approach allows compact storage and transport of individual modules, which can then be efficiently assembled in 3D space at the construction site, optimizing both transport volume and assembly speed

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
