Scaffolding Console Railing Intermediate Sleeve Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems face challenges in efficiently extending to reach eaves and gutters, requiring additional special parts and manual labor, and struggle with secure attachment of outriggers and accessories due to compatibility issues with standard components.
Innovation Solution
The scaffolding system incorporates an enlarged coupling recess on assembly frames and console front railings, allowing for the insertion of an intermediate sleeve or spacer sleeve to securely attach consoles and accessories, enabling easy and quick assembly using standard components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If consoles are screwed to the scaffolding using pipe couplings, then the scaffolding can be extended to reach eaves and gutters, but the assembly process becomes time-consuming and expensive
Solution Approach 1:
The patent introduces an intermediate sleeve as a mediator component that connects the connecting pin of the assembly frame to the coupling recess of the console. This intermediate sleeve enables a direct plug-in connection, eliminating the need for time-consuming screwing operations with pipe couplings while maintaining the extended reach capability to eaves and gutters
Solution Approach 2:
The intermediate sleeve is nested within the coupling recess, creating a hierarchical nesting structure where the connecting pin inserts into the intermediate sleeve, which in turn is received by the coupling recess. This nesting arrangement enables quick assembly through simple insertion movements without requiring additional fastening operations
2Length of stationary object
If special extension parts are used to extend scaffolding, then the reach to eaves is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The intermediate sleeve is designed as a universal component that can be used in multiple locations and configurations within the scaffolding system. The same intermediate sleeve design can be applied whenever console extensions are needed, eliminating the need for numerous special-purpose extension parts and reducing overall device complexity
Solution Approach 2:
The extension functionality is segmented into a separate, standardized intermediate sleeve component rather than being integrated into the main assembly frame or console designs. This segmentation allows the extension capability to be added or removed independently and enables standardized manufacturing of the intermediate sleeve as a separate off-the-shelf component
3Reliability
If the connecting pin is blocked for further attachments, then the current connection is secure, but additional accessories must be attached elsewhere with non-compatible parts
Solution Approach 1:
The intermediate sleeve is nested within the coupling recess but leaves the top opening accessible, creating a nested structure that maintains secure connection while preserving attachment flexibility. The connecting pin is securely received by the intermediate sleeve, yet the intermediate sleeve itself remains accessible for additional accessory attachments
Solution Approach 2:
The intermediate sleeve serves multiple functions: it provides a secure connection between the connecting pin and coupling recess, maintains structural stability, and simultaneously serves as a mounting surface for additional accessories. This multi-functionality eliminates the need to choose between secure connection and attachment flexibility

AI summary
The frame has two vertical connection pins (21) inserted into a complementary connection access (22) at a lower side of a positioning frame (2) or a console front-end railing (1). The recess to a coupling recess (23) is enlarged at the lower side of the frame or the console front-end railing. The coupling recess is arranged at a distance from a large part of an inner surface of the recess to the inserted connection pins. A spacer sleeve (41) is inserted into a formed cavity, and a console (4) is fastened to the sleeve. A horizontal support (3) is fastened as a front head to the frame.
