Solution Overview
Problem
Existing space frame construction methods are hindered by complex mechanisms for joining rod and nodal elements, resulting in high labor costs and reduced efficiency in assembly and manufacturing.
Innovation Solution
The use of standardized polyhedral nodal elements with threaded holes and tubular cylindrical rods, along with a detachable sleeve connection system, simplifies assembly and maintains structural strength by allowing for easy attachment and detachment of rods with hexagonal lock nuts for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex mechanisms for joining rod and nodal elements are used, then connection strength is improved, but labor costs and assembly complexity increase
Solution Approach 1:
The connection mechanism is divided into separate functional elements: the rod with external thread, the nodal element with threaded hole, and the sleeve with internal thread. This segmentation allows each component to be optimized independently while maintaining overall connection strength, reducing assembly complexity through standardized interfaces
Solution Approach 2:
The sleeve acts as an intermediary element that mediates the connection between rods and nodal elements. It provides a standardized interface that simplifies assembly while maintaining connection strength, allowing for easy attachment and detachment without complex mechanisms
2Strength
If complex mechanisms for joining rod and nodal elements are used, then connection strength is improved, but manufacturing costs increase
Solution Approach 1:
The standardized threaded interface and sleeve design create universal connection elements that can be used across different rod and nodal element configurations. This universality reduces manufacturing costs through economies of scale and standardized production processes while maintaining connection strength
Solution Approach 2:
The sleeve is designed as a simple, easily manufactured component that can be produced cost-effectively. Its standardized design allows for efficient mass production, reducing overall manufacturing costs while providing sufficient connection strength for the application
3Productivity
If standardized parts are used, then assembly speed is improved, but adaptability to different rod junction angles is reduced
Solution Approach 1:
The standardized nodal element with threaded holes and sleeve interface is designed to be multi-functional, accommodating rods at different angles and configurations. The polyhedral shape of the nodal element provides multiple attachment points that can adapt to various spatial requirements while maintaining standardized connection mechanisms
Solution Approach 2:
The system allows for parameter changes in rod orientation and junction angles while maintaining standardized connection components. The standardized threaded interface and sleeve design remain constant, while the configuration parameters (angles, positions) can be varied to meet different structural requirements

AI summary
The invention relates to the field of building, and more particularly to a space frame, and can be used for creating wall structures, columns, supports, ceilings and complex dome structures for different purposes. The space frame comprises rods and polyhedral nodes with threaded apertures on the faces thereof for fastening said rods, wherein the rods have a tubular cylindrical shape and have an external thread on their ends, the diameter of the external thread of a rod corresponding to the diameter of a threaded aperture, and the space frame further comprises a coupling with an internal thread, capable of detachably connecting rods. The technical result is that of simplifying and expediting assembly by standardizing the component parts, while at the same time preserving the strength of the space frame.
