Square Truss Cross-Joint Structure for Stable Modular Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metallic room structures with triangular strut configurations offer limited stability and flexibility, especially in office settings, where stability and ease of reconfiguration are critical. Current modular systems are either unstable or require complex assembly and are not cost-effective for basic elements.
Innovation Solution
The development of a right-angled half-timbered framework with special recesses in the struts that enable crossing and form closure when clamped using screw connections, providing high angle stability and allowing for easy assembly and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If diagonal bracing to form stabilizing triangles is used in traditional warehouse racking, then stability is improved, but aesthetic requirements cannot be met and the design is inherently impractical for office environments
Solution Approach 1:
The patent divides the stabilization function into separate components: corner elements provide localized stabilization while the main truss members maintain clean straight lines. The corner elements are segmented from the main structure, allowing stabilization without compromising the aesthetic appearance of the primary framework.
Solution Approach 2:
Stabilization is applied locally at the corner elements rather than through diagonal bracing across the entire structure. This localized approach provides the necessary stability at critical points while maintaining the clean, uncluttered appearance of the main truss members and surfaces.
2Stability of the object's composition
If floor and wall inserts or cabinet elements are used to provide localized stabilization, then stability is improved, but rigid connection to the truss is required which makes subsequent modifications extremely difficult
Solution Approach 1:
The corner elements are designed with dynamic connection capabilities, allowing them to be rigidly connected when stability is needed but also easily repositioned or reconfigured. The connection mechanism transitions from fixed to flexible, enabling the structure to adapt to changing requirements while maintaining stability during use.
Solution Approach 2:
The corner elements are pre-designed with integrated stabilization features that can be activated or deactivated as needed. The connection system is prepared in advance to allow both rigid connection for stability and easy modification for reconfiguration, eliminating the need for complex field modifications.
3Adaptability or versatility
If modular systems with rod and node components are used, then flexibility and ease of reconfiguration are improved, but stability is reduced compared to triangular trusses
Solution Approach 1:
The patent merges the advantages of modular systems with the stability of triangular trusses by incorporating corner elements that provide localized triangulation. The main structure retains modular flexibility with straight truss members and standard connectors, while the corner elements add stability without compromising the modular nature of the system.
Solution Approach 2:
The structure combines different structural approaches: standard modular truss members for flexibility and stability-providing corner elements with triangulated geometry. This composite approach integrates two different structural systems to achieve both modular flexibility and enhanced stability.
4Stability of the object's composition
If complex connections are used to achieve high angular stability, then stability is improved, but assembly time increases and the system becomes less practical for office environments
Solution Approach 1:
The complex angle-stabilizing function is extracted from the main connection system and placed into specialized corner elements. This allows the primary truss connections to remain simple and quick to assemble, while the corner elements provide the necessary angular stability at critical locations without adding complexity to the overall assembly process.

AI summary
A truss structure for offices, public spaces, and private rooms is presented, forming a rectangular and right-angled framework with specific grid dimensions. Floors, side and back panels, or small cabinet, compartment, or shop elements can be inserted into the openings for various uses. The use of continuous struts, which feature novel recesses at their intersections to form a cross-joint (31), achieves particularly high angular stability. This is achieved by the interlocking recesses (23) of the cross-shaped radii, creating a positive fit under a screw force. This allows for the creation of basic elements in specific sizes and heights, as well as truss structures designed according to customer specifications.The recesses (21) arranged at the strut ends form smooth corners and edges on the outside, allowing connectors (41) and connecting struts to be attached at any point on the struts and to fit precisely into the structure. This creates a hybrid system that combines highly stable basic elements with supplementary elements while maintaining the design.
