Solution Overview

Problem

Traditional construction methods for buildings are time-consuming and require multiple skill sets, extending the construction period to several months, which is undesirable for rapid structure development.

Innovation Solution

The use of additive manufacturing techniques, specifically 3D printing, to construct structures by depositing extrudable building materials in vertically stacked layers, allowing for the simultaneous formation of walls, windows, and infill, with a computer-controlled printing assembly and non-transitory computer-readable medium defining master slices and tool paths for efficient construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional construction methods are used, then multiple skill sets and conventional processes are employed, but construction time is extended to several months

Engineering Contradiction:
Improveconstruction speedVSAvoidconstruction period
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent changes the state of building materials to an extrudable form that can be deposited layer by layer, fundamentally altering the construction process from traditional assembly methods to additive manufacturing. This parameter change enables continuous construction without the need for multiple skill sets and dramatically reduces construction time from months to days or hours.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional mechanical construction systems (manual labor, heavy machinery, multiple trades) with a computer-controlled printing assembly that deposits material precisely according to digital models. This substitution eliminates the need for multiple skill sets and accelerates the construction process significantly.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If additive manufacturing techniques are used, then construction time is significantly reduced, but new manufacturing processes and equipment are required

Engineering Contradiction:
Improveconstruction periodVSAvoidprinting assembly complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The printing assembly is designed as a multi-functional system that can deposit various types of building materials (concrete, mortar, insulation materials) through a single integrated platform. This universality reduces the need for multiple specialized construction equipment and skill sets, making the complex technology more manageable and adaptable to different construction needs.

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

Solution Approach 2:

The construction process is segmented into discrete vertical slices and horizontal layers that can be deposited independently by the printing assembly. This segmentation allows the complex construction task to be broken down into manageable steps, controlled by computer software that generates toolpaths for each slice, thereby managing device complexity through systematic decomposition.

Inventive Principle:
Principle #1Segmentation

3Shape

If vertical slices with different lateral cross-sections are deposited, then complex structural shapes are achieved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvestructural complexityVSAvoidlayer deposition accuracy
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent employs preliminary action by creating digital 3D models and generating computer-controlled toolpaths before construction begins. The master slice and subsequent vertical slices are precisely calculated in advance, allowing the printing assembly to follow predetermined paths that ensure accurate deposition of each layer. This pre-planning compensates for the increased precision requirements by eliminating manual measurement and positioning errors.

Inventive Principle:
Principle #10Preliminary action
