Single-Layer Space Frame Node Concealing Screw Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-layer space frame systems have exposed screwing means between nodes and struts, which can be aesthetically unappealing and lack protection, compromising the visual continuity and durability of the frame.
Innovation Solution
The system incorporates overlapping covers formed by portions of struts with matching sections, containing and concealing the connection means, including threaded holes and screwing elements, to create a seamless integration of struts and nodes, maintaining structural integrity while enhancing aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screwing means are used to connect struts to nodes, then structural integrity and assembly security are improved, but aesthetic appearance and visual continuity deteriorate due to exposed connection elements
Solution Approach 1:
The connection means are nested within the node body. The node is designed with a recessed cavity that receives and hides the screwing elements, allowing the connection mechanism to be concealed while maintaining its structural function. This nesting approach eliminates the need for external covering plates or caps, achieving clean aesthetics without compromising connection strength.
Solution Approach 2:
The node acts as an intermediary element that mediates between the strut and the connection mechanism. By integrating the screwing means within the node's geometry rather than exposing them externally, the node serves as a mediator that hides the connection details while maintaining the structural relationship between struts and nodes.
2Ease of operation
If connection means are exposed between nodes and struts, then ease of assembly and maintenance are improved, but protection and durability of connection areas deteriorate
Solution Approach 1:
The connection means are nested within the node body, which provides inherent protection for the screwing elements. The node's recessed cavity shields the connection areas from environmental factors such as moisture, corrosion, and mechanical damage, thereby improving durability and reliability without requiring additional protective components.
3Shape
If covering means are added to conceal connection means, then aesthetic appearance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The covering function is merged with the node itself. Instead of adding separate covering plates, caps, or protective elements, the node is designed to inherently conceal the connection means through its recessed geometry. This merging of the covering function into the node's basic structure eliminates additional parts and simplifies manufacturing while achieving the desired aesthetic appearance.
Solution Approach 2:
The node serves multiple functions: it provides structural connection, conceals connection means, and protects screwing elements. By making the node multi-functional, the design eliminates the need for separate covering components, thereby reducing device complexity and manufacturing cost while achieving improved aesthetic appearance.
