Connecting Node for Modular Framework Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting structures, such as vertical masts, require complex mechanical rework for attaching and removing functional modules, limiting flexibility and ease of use, especially when multiple modules need to be installed or removed at various heights.
Innovation Solution
A connecting node system comprising two node shells with sliding blocks and fastening nuts that can be securely attached at any height without mechanical rework, allowing for easy assembly and disassembly, and featuring fastening screws that press the node shells against the structure, enabling stable attachment without needing to be pushed onto the structure from above.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional modules are attached to supporting structures using fixed brackets or sliding-on methods, then the modules can be securely fastened, but mechanical rework and complex installation procedures are required
Solution Approach 1:
The connecting node is divided into two separate node shells that can be independently positioned and attached to the supporting structure. Each node shell can be attached separately using the groove system, allowing modular assembly without complex integrated mechanisms.
Solution Approach 2:
The groove system acts as an intermediary element between the node shells and the supporting structure. The grooves provide a standardized interface that simplifies the attachment process, eliminating the need for complex mechanical rework by serving as a pre-prepared mounting interface.
2Adaptability or versatility
If functional modules are installed at various heights on supporting structures, then versatility and flexibility are improved, but mechanical processing and modification are required at each location
Solution Approach 1:
The groove system is designed as a universal interface that can accommodate node shells at any height along the supporting structure. The same groove configuration and attachment mechanism can be used throughout the entire structure, eliminating the need for location-specific mechanical modifications.
Solution Approach 2:
The grooves are pre-formed on the supporting structure during manufacturing, creating ready-to-use attachment interfaces at all possible locations. This preliminary preparation eliminates the need for on-site mechanical processing when installing functional modules at various heights.
3Reliability
If node shells are attached using traditional fastening methods, then secure attachment is achieved, but the attachment process becomes time-consuming and complex
Solution Approach 1:
The node shells are designed to attach to the supporting structure through their own integrated grooves that engage with the supporting structure's groove system. This self-contained attachment mechanism eliminates the need for separate complex fastening operations while maintaining secure attachment.
Solution Approach 2:
The attachment function and the structural interface are merged into the groove system itself. The grooves serve both as structural features of the supporting structure and as the fastening interface, combining multiple functions into a single integrated system that reduces attachment time.
