Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection nodes for supporting structures are complex to assemble, prone to incorrect assembly, inflexible, and vulnerable to mechanical loads, leading to low resilience and service life.
Innovation Solution
A connection node with a central mounting body and adapter elements that provide form-fitting receptacles and fastening points in various directions, allowing for easy assembly, load distribution, and flexibility, using bolt-shaped connecting elements with threads for secure and detachable attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional connecting nodes with pre-programmed weak points are used, then assembly is simplified, but load-bearing capacity and service life are reduced
Solution Approach 1:
The connecting node is divided into multiple independent adapter elements that can be separately assembled and distributed around the central mounting body. This segmentation allows each adapter element to independently bear loads without creating pre-programmed weak points, while maintaining easy assembly through modular construction
Solution Approach 2:
The adapter elements are pre-designed with form-fitting receptacles and connecting features that guide correct assembly before final tightening. This preliminary configuration ensures proper load distribution paths are established before full mechanical engagement, preventing weak point formation during assembly
2Strength
If complex connection systems with multiple components are used, then load distribution is improved, but assembly time and space requirements increase
Solution Approach 1:
Multiple functional features (form-fitting receptacles, bolt mounting points, rod connection interfaces) are merged into integrated adapter elements. This combination maintains excellent load distribution through multiple connection points while reducing assembly steps by eliminating the need to separately install multiple discrete components
Solution Approach 2:
The adapter elements are pre-assembled with adapter elements on the mounting body side before final installation. This preliminary assembly creates ready-to-install modules that maintain complex load distribution capabilities while significantly reducing on-site assembly time and spatial requirements
3Stability of the object's composition
If traditional connection nodes are used, then structural stability is achieved, but flexibility and adaptability are reduced
Solution Approach 1:
The connecting node system transitions from a fixed, pre-programmed configuration to a dynamic, adaptable system where adapter elements can be selectively added, removed, or reconfigured. This allows the structure to maintain stability through form-fitting connections while gaining flexibility to adapt to different loading conditions and spatial requirements
Solution Approach 2:
The adapter elements are designed with universal form-fitting receptacles and standardized connecting features that can accommodate various rod configurations and loading scenarios. This multi-functionality enables the same basic adapter design to serve multiple purposes while maintaining structural stability through consistent form-fitting engagement
