Retaining Profile for Frame-Integrated Fall Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame profile attachment methods, such as using rotary holders or clip holders, are inadequate for withstanding compressive stresses and do not allow for easy integration of fall protection elements like parapet grids or panes, requiring significant processing and being prone to wear and tear.
Innovation Solution
A frame-integrated design featuring a retaining profile with a Z-shaped offset and groove system that allows for easy alignment and screw-based mechanical connection of frame profiles, enabling secure attachment without modifying the frame profile's mounting groove, thus providing enhanced mechanical strength against suction and pressure forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rotary holders or clip holders are used to attach frame profiles, then installation is simple, but mechanical strength against compressive stress and suction forces is insufficient
Solution Approach 1:
The patent combines the holding profile and frame profile into a single integrated mechanical connection system. The holding profile is not merely attached to the frame but is merged with it through direct mechanical engagement, creating a unified structure that resists both compressive stress and suction forces while maintaining installation simplicity.
Solution Approach 2:
The holding profile is pre-configured with specific geometric features (protrusions, recesses, engagement surfaces) that are designed in advance to mate with corresponding features on the frame profile. This preliminary design enables the connection to inherently resist compressive and suction forces without requiring additional fastening operations during installation.
2Strength
If frame profiles are attached in sections using screwed holders, then mechanical strength is improved, but assembly complexity and processing requirements increase
Solution Approach 1:
The holding profile is segmented into distinct functional zones: a mounting section that attaches to the frame, a connection section that engages with the frame profile, and intermediate sections that provide structural continuity. This segmentation allows each zone to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The holding profile serves multiple functions simultaneously: it provides mechanical attachment to the frame, creates a weather seal, establishes structural continuity, and enables the frame profile to resist both compressive and suction forces. This multi-functionality eliminates the need for separate components for each function, reducing assembly complexity.
3Ease of operation
If conventional rotary holders are used, then installation is straightforward, but resistance to pressure from inside outwards is insufficient for fall protection
Solution Approach 1:
The holding profile employs asymmetric geometric features where protrusions on one side engage with corresponding recesses on the frame profile. This asymmetric design creates a mechanical interlock that is specifically optimized to resist pressure forces from inside outwards, while still allowing straightforward installation from the outside.
Solution Approach 2:
The solution transitions from a two-dimensional attachment surface to a three-dimensional mechanical interlock. The holding profile creates engagement in multiple spatial dimensions through its protrusions and recesses, enabling it to resist pressure forces from multiple directions while maintaining installation simplicity.
4Strength
If wedge-shaped clamping connections are used to fasten cover profiles, then mechanical strength is achieved, but wear and tear increases and assembly becomes difficult
Solution Approach 1:
The patent extracts the problematic wedge-shaped clamping mechanism and replaces it with a direct mechanical engagement system. The holding profile and frame profile engage through complementary geometric features that distribute loads evenly, eliminating the concentrated stress points that cause wear and material breakage in wedge-shaped connections.
Solution Approach 2:
The connection geometry is changed from a wedge-shaped interface to a multi-surface mechanical interlock. This parameter change in the geometric configuration allows the connection to achieve equivalent or superior mechanical strength while distributing contact forces across multiple surfaces, thereby reducing wear and increasing reliability.
