Solution Overview

Problem

Conventional manufacturing techniques, such as welding, are inefficient and costly for joining additively manufactured parts to conventional commercial components, as they often require costly materials and are time-intensive, and may not be viable for new materials used in additive manufacturing.

Innovation Solution

The method of co-printing additively manufactured nodes and interconnects using additive manufacturing processes, which allows for the creation of complex geometries and structures that can securely connect nodes to components or tubes through the use of injection ports and vacuum ports for adhesive application, eliminating the need for traditional welding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional welding techniques are used to join additively manufactured parts to commercial components, then structural integrity can be achieved, but manufacturing time and costs increase significantly

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing time
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The node and interconnect are co-printed as a single integrated component using additive manufacturing, eliminating the need for separate joining operations like welding. This merging of previously separate parts into one co-printed unit directly reduces manufacturing time while maintaining structural integrity through the continuous material structure created during the co-printing process

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If conventional welding techniques are used to join additively manufactured parts to commercial components, then structural integrity can be achieved, but material costs and process complexity increase

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

By combining the node and interconnect into a single co-printed component, the invention eliminates the need for additional welding materials, consumables, and specialized welding equipment. This reduces material costs and simplifies the manufacturing process, making it more accessible and cost-effective while preserving structural integrity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The co-printing process inherently creates the integrated node-interconnect structure without requiring external joining operations. The additive manufacturing process itself performs the joining function during fabrication, eliminating the need for separate welding processes and associated costs

Inventive Principle:
Principle #25Self-service

3Strength

If conventional welding techniques are used to join additively manufactured parts to commercial components, then structural integrity can be achieved, but the process becomes time-intensive and less efficient

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The node and interconnect are co-printed together in a single additive manufacturing process before assembly with commercial components. This preliminary integration eliminates the need for time-consuming welding operations that would otherwise be required during final assembly, significantly reducing total manufacturing time while ensuring structural integrity is built-in from the start

Inventive Principle:
Principle #10Preliminary action
