Solution Overview

Problem

Existing industrial gantry systems are limited in their ability to achieve high print accuracy on complex surfaces with non-horizontal features and projections, as they typically restrict access to small surface areas and do not allow for precise positioning on non-flat surfaces, leading to issues with print overlap.

Innovation Solution

A multi-axis gantry system with a reconfigurable frame and vacuum attachment points, allowing the system to be mounted on different work surfaces and featuring a carriage and bridge mechanism with pucks that can be repositioned for secure vacuum attachment, enabling precise positioning and printing on complex surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If existing industrial gantry apparatus are used with tall and large structure, then they can cover large work surfaces, but they cannot access small surface print areas created by changes in elevation or surface features

Engineering Contradiction:
Improvework surface coverage areaVSAvoidaccess to small surface print areas
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The gantry system is divided into modular components including a bridge structure with multiple carriages that can independently position end effectors. This segmentation allows the system to access small surface areas while maintaining large work surface coverage through coordinated movement of modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates multi-axis movement capabilities with carriages that can position end effectors in three-dimensional space, allowing access to non-horizontal surfaces and areas with elevation changes by moving beyond the traditional planar gantry configuration.

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

2Stability of the object's composition

If existing gantry apparatus are designed for broad flat panel work zones, then they provide stable mounting, but they do not allow printing access to non-horizontal surfaces

Engineering Contradiction:

Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system employs dynamically positionable end effectors mounted on carriages that can move along the bridge structure, enabling the end effectors to reach non-horizontal surfaces while the main gantry structure remains stable and fixed during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by allowing end effectors to operate at varying positions and orientations along the bridge, adapting to non-horizontal surfaces while the main structure maintains its stable configuration.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If existing gantry apparatus are used without reconfigurable features, then they simplify manufacturing, but they cannot be repositioned for different work surface geometries

Engineering Contradiction:

Solution Approach 1:

The system uses modular, segmented components that can be independently positioned and configured for different work surface geometries, maintaining manufacturing simplicity through standardized modular units while enabling repositioning flexibility.

Inventive Principle:

Solution Approach 1:

The system incorporates feedback mechanisms through controllers that monitor and adjust the position of carriages and end effectors, ensuring precise print positioning at borders while managing system complexity through automated control.

Inventive Principle:

Solution Approach 2:

The system replaces complex mechanical positioning mechanisms with automated control systems that use sensors and controllers to achieve precise positioning, reducing mechanical complexity while maintaining or improving print accuracy.

Inventive Principle:
