Solution Overview

Problem

Current additive manufacturing technologies are limited by the dimensions of the workspace and the ability of equipment to move in multiple dimensions, restricting the size and complexity of objects that can be produced.

Innovation Solution

The development of a mobile additive manufacturing apparatus, called Addibot, which combines robotic mobility with additive manufacturing techniques, allowing for independent or automated movement and deposition of materials across surfaces using a drive system, navigation system, controller, and additive manufacturing system, enabling the creation of complex three-dimensional structures over significant distances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If traditional additive manufacturing equipment is used with fixed workspaces, then manufacturing precision can be maintained, but the size and complexity of objects that can be produced are limited

Engineering Contradiction:
Improvesize of producible objectsVSAvoidspatial limitations
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the additive manufacturing system from a static fixed-workspace configuration to a mobile robotic system that can dynamically reposition itself and its manufacturing equipment across large surfaces, thereby overcoming spatial limitations and enabling production of larger and more complex objects

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces mobility as an additional dimension to the traditional additive manufacturing process. By enabling the equipment to move across the workspace rather than being confined to a fixed position, the system gains freedom in spatial arrangement and can access areas that would otherwise be unreachable, effectively adding a dimensional aspect to the manufacturing capability

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

2Shape

If the work head moves in multiple dimensions within a fixed workspace, then complex three-dimensional shapes can be formed, but the dimensions of the workspace restrict the overall scale of production

Engineering Contradiction:
Improvecomplexity of three-dimensional structuresVSAvoidmaximum production scale
Core Design Contradiction:
ShapeVSLength of stationary object

Solution Approach 1:

The system maintains the capability to form complex three-dimensional shapes while overcoming workspace dimension limitations by making the entire additive manufacturing apparatus mobile. The robotic system can reposition the work head and support structure to different locations, allowing complex shapes to be constructed across a much larger scale than fixed-workspace systems permit

Inventive Principle:
Principle #15Dynamics

3Length of stationary object

If additive manufacturing equipment is made mobile with drive systems and navigation capabilities, then production of large-scale structures is enabled, but device complexity increases

Engineering Contradiction:
Improvescale of producible structuresVSAvoidmobility system complexity
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The mobile robotic system integrates multiple functions into a single platform: the drive system provides both mobility for repositioning and positioning accuracy for manufacturing precision, while the navigation system simultaneously enables autonomous navigation and spatial awareness. This multi-functionality reduces the need for separate dedicated systems, thereby managing complexity while achieving large-scale production capability

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

AI summary

Mobile and automated processing utilizes additive manufacturing. Methods include the utilization of mobile and automated processing apparatus. The mobile additive manufacturing apparatus may perform surface treatments that alter the topography of an existing roadway surface. Other examples may involve the processing of dimensionally large layers which may be joined together to create large pieces with three dimensional shape. A mobile additive manufacturing apparatus, called an Addibot, is configured to comprise a drive system which may be operative to move the apparatus along a surface. The Addibot may function with no physical tether. The Addibot may comprise a navigation system which among other functions may determine the Addibot' s current location and its current bearing or direction that it would travel in when caused to move or is travelling in if moving.
