Solution Overview

Problem

Conventional manufacturing processes struggle to efficiently join components with complex internal geometries, particularly those requiring deformation to fit unique internal structures, such as tapered sockets, due to limited flexibility and configurational constraints.

Innovation Solution

Additive manufacturing techniques are used to print nodes with tapered sockets and deformable panels, where the panel's surface layers and core are designed to conform to the node's shape, allowing for a stronger and simpler bond through the use of fillers and adhesives that can be compressed or expanded to fit the socket's geometry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional manufacturing processes are used to join components with complex internal geometries, then manufacturing simplicity is maintained, but the ability to create unique internal structures and configurational flexibility is limited

Engineering Contradiction:
Improveconfigurational flexibilityVSAvoidinternal geometric complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by creating nodes with non-uniform, location-specific internal geometries that are tailored to the exact deformation requirements of each panel. The additively manufactured nodes have varying wall thicknesses, curvature radii, and socket geometries at different locations, allowing each region of the node to be optimized for its specific function in shaping the panel during bonding.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes the third dimension by creating complex internal geometries within the nodes that cannot be achieved through conventional 2D machining or molding. The additively manufactured nodes feature multi-layered internal structures, varying cross-sections, and three-dimensional socket configurations that enable sophisticated panel deformation patterns.

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

2Adaptability or versatility

If additively manufactured nodes with unique internal structures are used, then configurational flexibility and customization are improved, but the difficulty of joining deformable panels to these nodes increases

Engineering Contradiction:
Improvecustomization capabilityVSAvoidjoining difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by pre-designing the nodes with built-in deformation zones and tapered sockets that guide the panel deformation process. The nodes are manufactured with predetermined geometric features that automatically shape the panel as it is bonded, eliminating the need for complex post-manufacturing adjustments or specialized joining equipment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by varying the geometric parameters of the node sockets and deformation zones to match the specific requirements of different panel types. The additively manufactured nodes can have adjustable curvature radii, wall thicknesses, and socket angles that are optimized for each application, making the joining process easier despite the complexity of the structures.

Inventive Principle:

Solution Approach 1:

The patent merges the node manufacturing and panel deformation processes into a single additive manufacturing operation. The nodes are printed with integrated deformation zones that perform both structural support and panel shaping functions, eliminating the need for separate deformation equipment and reducing overall manufacturing process complexity despite the high interconnection strength achieved.

Inventive Principle:
