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

VSEngineering 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

Engineering Contradiction:
Improveease of attachmentVSAvoidmechanical rework complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improveheight flexibilityVSAvoidmechanical processing requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If node shells are attached using traditional fastening methods, then secure attachment is achieved, but the attachment process becomes time-consuming and complex

Engineering Contradiction:
Improveattachment securityVSAvoidattachment time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #5Merging (Combining)
