Geodesic Frame Hub Connector for Faster Multi-Strut Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional geodesic frame connector systems are complex and time-consuming to assemble due to the numerous parts required, particularly in hub connectors that need specific configurations for different strut arrangements, leading to increased complexity and difficulty in construction.
Innovation Solution
A geodesic frame connector system utilizing a discontinuous ring pair with a fastener that separates the rings, allowing elongated struts to be easily positioned and secured, reducing the need for multiple parts and configurations by using a single type of hub connector for various strut arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional hub connectors are used with multiple pins and caps for six-strut connections, then the structural integrity is maintained, but the assembly complexity and time increase significantly
Solution Approach 1:
The patent combines multiple separate components (six pins and six caps in conventional systems) into a single integrated hub connector body with continuous circumferential grooves. This merging reduces the number of parts from twelve separate components to one unified structure, significantly simplifying assembly while maintaining the structural integrity required for six-strut connections.
Solution Approach 2:
The hub connector is designed with a universal structure that can accommodate different numbers of struts (e.g., three, four, five, or six struts) by selectively positioning struts relative to the circumferential grooves. This multi-functional design eliminates the need for different hub configurations for different strut counts, reducing inventory complexity and assembly difficulty.
2Adaptability or versatility
If multiple different hub connector configurations are used for different strut arrangements, then the adaptability to various dome frequencies is improved, but the device complexity and part quantity increase
Solution Approach 1:
The hub connector features a universal design with continuous circumferential grooves that can accommodate struts at various angular positions. This allows a single hub type to serve multiple dome frequencies and strut arrangements (e.g., 3-strut, 4-strut, 5-strut, or 6-strut configurations) without requiring different hub designs, thereby improving adaptability while reducing part variety.
Solution Approach 2:
The hub connector incorporates movable or adjustable elements within the circumferential grooves that allow the structure to adapt to different strut configurations. This dynamic capability enables the same hub to function with varying numbers and arrangements of struts, enhancing versatility without increasing the number of different part types.
3Manufacturing precision
If conventional hub connectors with multiple discrete parts are used, then the manufacturing precision can be maintained, but the ease of operation during assembly deteriorates
Solution Approach 1:
The patent integrates multiple discrete components into a single monolithic hub connector manufactured as one piece. This merging maintains manufacturing precision through conventional machining of the unified structure while dramatically improving ease of assembly, as users no longer need to locate, sort, and manipulate multiple small parts (pins and caps) during construction.
Solution Approach 2:
While the hub itself is unified, the design incorporates segmented circumferential grooves that create natural alignment zones for struts. This segmentation provides built-in positioning features that guide strut insertion and ensure proper angular orientation, maintaining precision without requiring complex assembly procedures or multiple precision-machined components.

AI summary
A geodesic frame connector system for a geodesic frame and method are provided comprising a first discontinuous ring having a first discontinuous ring upper and lower faces, the first ring upper face including an opening extending through the first discontinuous ring, and having inner and outer ring perimeters. A second discontinuous ring is provided having second discontinuous ring upper and lower faces, and inner and outer ring perimeters, and a fastener is provided having a cross section smaller than the opening. When one of the first discontinuous ring lower face and upper face is placed adjacent one of the second discontinuous ring lower face and upper face, insertion of the fastener in the opening of the first discontinuous ring causes the fastener to contact the second discontinuous ring, thereby forcing the second discontinuous ring away from the first discontinuous ring.
