Scaffold Connection Disc With Blocking Regions for Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffold connecting discs are unsuitable for transferring larger momentums due to limited connection stability, leading to unsteadiness and potential safety risks, and they fail to compensate for positioning errors between scaffold elements.
Innovation Solution
A connecting disc with a basic body featuring a longitudinal opening and transverse openings, including blocking regions for positive connections and curved contact areas for rotational compensation, allowing for high torque transfer while accommodating positioning errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a known connecting disc with simple openings is used, then the assembly and disassembly is easy, but the transfer of momentums is limited and causes unsteadiness
Solution Approach 1:
The connecting disc is divided into multiple functional openings: a central longitudinal opening for vertical connection and multiple transverse openings for horizontal connections. Each opening type serves a specific function, allowing the disc to handle different types of loads and momentums independently, thereby improving stability while maintaining ease of assembly.
Solution Approach 2:
Different regions of the connecting disc are designed with different properties: the longitudinal opening provides vertical load bearing capability, while the transverse openings provide horizontal connection and momentum transfer. The peripheral contour with blocking regions creates localized engagement zones that prevent rotation and enhance stability without complicating the overall assembly process.
2Device complexity
If a known connecting disc with simple openings is used, then the structure is simple, but positioning errors between scaffold elements cannot be compensated
Solution Approach 1:
The peripheral contour of the transverse openings is designed with blocking regions that can engage with corresponding features on scaffold elements. This dynamic engagement allows the connecting disc to accommodate minor positioning errors through controlled movement within the blocking regions, providing adaptability while maintaining a relatively simple overall structure.
3Reliability
If larger momentums are transferred through the connection, then the scaffold section becomes more stable, but the connection interface becomes more complex
Solution Approach 1:
The connection interface is segmented into multiple openings with specific functions: the longitudinal opening handles vertical loads, while transverse openings handle horizontal momentums. This segmentation allows each opening to be optimized for its specific function, enabling transfer of larger momentums without requiring a completely complex redesign of the entire connection interface.
Solution Approach 2:
The connecting disc is designed as a multi-functional component that simultaneously provides vertical connection, horizontal connection, rotation prevention, and positioning error compensation. By integrating multiple functions into a single component with a systematic arrangement of openings, the design achieves high momentum transfer capability without proportionally increasing overall complexity.
