Adjustable Railing Support Device for Damage-Free Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railing support devices for fall protection often damage existing facades or obstruct work areas, limiting their application to new buildings with bare masonry, as they require direct attachment to the wall and cannot be adjusted in distance from the facade.
Innovation Solution
A railing support device with adjustable fastening elements that can be securely attached to various types of walls without damaging the facade, featuring through holes for receiving fastening elements and spacer/retaining nuts to clamp the support element, allowing for flexible positioning and secure fastening without counter-pressure on the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the railing support device is fixed directly to the wall, then the fall protection device can be securely attached, but the work area becomes obstructed and inaccessible
Solution Approach 1:
The support element is extended in the direction perpendicular to the wall surface, creating spatial separation between the attachment point (on the wall) and the functional element (support element). This dimensional extension allows the work area to remain accessible while maintaining secure attachment through the extended support structure.
2Ease of manufacture
If the support element rests against the wall, then the installation is simple, but existing facades are damaged
Solution Approach 1:
Fastening elements serve as intermediaries between the support element and the wall. Instead of the support element directly contacting and potentially damaging the facade, the fastening elements penetrate the wall to provide secure attachment while the support element remains separated, preventing damage to the facade surface.
3Stability of the object's composition
If the support element is positioned at a fixed distance from the wall, then the structure is stable, but it cannot accommodate different facade types
Solution Approach 1:
The distance between the support element and the wall is made adjustable rather than fixed. The fastening elements can be positioned at different depths and the support element can be placed at variable distances from the wall surface, allowing adaptation to different facade types while maintaining structural stability through proper fastening.
4Reliability
If the railing support device is attached to the facade, then fall protection is provided, but the attachment location is damaged
Solution Approach 1:
The fastening elements act as intermediaries that bear the attachment load and penetrate the wall, while the support element that provides fall protection capability remains separated from the facade. This separation ensures that the protective function is maintained without direct contact that would cause damage to the mounting location.

AI summary
The device (10) has a support element (20) for receiving elements of guardrail. A fastening element (30) fastens the support element at a wall (60). The support element has through holes for receiving the fastening element in a direction of extension, where the through holes are spaced at a distance from each other. A spacer element (31) and an outer holding element (33), which are designed as nuts, are fixed at the fastening element such that the spacer and the holding elements intermediately clamps the support element, where distance of the support element to the wall is adjustable. An independent claim is also included for a guardrail with a rail protection device.
