Scaffold Railing Holder Assembly for Stable Lower-Level Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding components are complex, expensive, and lack stability, with railing elements requiring assembly from higher levels, posing safety risks and inefficiencies.
Innovation Solution
A railing element holder system that allows for detachable connection of railing elements to scaffolding uprights, featuring a first railing element with coupling elements and transverse connecting elements for secure attachment, enabling assembly from lower levels with enhanced stability and ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing scaffolding components are used, then the structure can be assembled, but the assembly process becomes complex and expensive with reduced stability
Solution Approach 1:
The patent combines multiple separate components (mounting plate, cross bolts, retaining plate, rocker arms, rotation axes) into an integrated railing element holder assembly. This merging of components simplifies the overall structure while maintaining stability, as the holder is designed as a coordinated system where each element serves a specific function in securing the railing element to the scaffolding upright.
Solution Approach 2:
The railing element holder is segmented into distinct functional components: a mounting plate for attachment to the upright, cross bolts for securing, a retaining plate for lateral retention, and rocker arms with rotation axes for controlled movement. This segmentation allows each component to be optimized independently while contributing to the overall stability and simplifying assembly procedures.
2Productivity
If railing elements are assembled from higher levels, then the structure can be secured, but safety risks increase and assembly efficiency decreases
Solution Approach 1:
The patent inverts the traditional assembly sequence by enabling railing elements to be assembled from lower levels rather than higher levels. The holder is designed with a mounting plate that attaches to the upright from below, and the retaining plate and cross bolts are configured to secure the railing element in an upward direction. This inversion allows workers to safely assemble railings from the ground or lower platforms, eliminating the need to work at height during railing installation.
Solution Approach 2:
The holder components are pre-configured and pre-positioned on the scaffolding upright before the railing element is installed. The mounting plate is attached to the upright, and the cross bolts and retaining plate are prepared in advance, allowing the railing element to be quickly and safely connected from a lower level without requiring workers to be positioned on higher platforms.
3Ease of manufacture
If multiple separate components are used for the railing holder, then the structure can be assembled, but manufacturing and assembly costs increase
Solution Approach 1:
The patent merges multiple functional components into a coordinated assembly where the mounting plate, cross bolts, retaining plate, and rocker arms work together as an integrated system. While these remain separate manufacturable parts, they are designed to be assembled together in a standardized configuration that reduces overall complexity compared to using entirely separate components for each function, thereby lowering manufacturing and assembly costs.

AI summary
The invention relates to an arrangement (15.1) of scaffolding components which comprises a scaffold post (17.1) with a holder (18.1) and a railing element (19.1). The latter has a railing strut (21.1) and a fastening hook (23.1). The holder (18.1) has a retaining wall part (34.1) for securing the railing element (19.1) against being laterally removed from the holder (18.1) in a direction away from the scaffold post (17.1). The holder (18.1) has a first transverse connecting element (35.1.1) for supporting the first railing element (19.1) and a second transverse connecting element (35.1.2) for supporting a second railing element. The retaining wall part (34.1), the first transverse connecting element (35.1.1) and the second transverse connecting element (35.1.2) delimit a first receiving space (38.1) in which the fastening hook (23.1) of the railing element (19.1) supported on the first transverse connecting element (35.1.1) is received. The first transverse connecting element (35.1.1) and the second transverse connecting element (35.1.2) are each directly connected to the first scaffold post (17.1) by welding, with the result that the first receiving space (38.1) is also delimited by the first scaffold post (17.1). Alternatively or additionally, the first holder (18.1) can be produced from one piece and/or formed as one part.
