Indirect Mounting of Fall Protection Structure on Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fall protection installations are inflexible and difficult to retrofit, often resulting in a tall structure that can collide with roller shutter systems and lack official approval due to complex statics and direct physical connections.
Innovation Solution
A mounting set that allows for indirect force coupling between the frame fastener and the fastening body via a metal profile, enabling separate mounting and ensuring reliable attachment of the fall protection structure to the anchoring base without direct physical contact, facilitating flexible retrofitting and high-strength protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fall protection device is installed using conventional direct connection methods, then the structure provides reliable protection, but the installation becomes inflexible and difficult to retrofit, and may collide with roller shutter systems
Solution Approach 1:
The mounting system is divided into separate components: a mounting set that attaches to the frame and a fastening body that attaches to the fall protection structure. These segments connect indirectly through the frame rather than directly, allowing independent positioning and avoiding interference with roller shutter systems while maintaining structural reliability
Solution Approach 2:
The frame serves as an intermediary element between the mounting set and the fastening body. The mounting set fastens to the frame using frame fasteners, while the fastening body fastens to the frame using separate fastening elements, creating an indirect connection path that provides flexibility and avoids direct collision with roller shutter mechanisms
2Reliability
If a tall structure is used for fall protection installation, then the protection coverage is improved, but the structure may collide with roller shutter systems
Solution Approach 1:
The mounting system utilizes the three-dimensional space around the frame opening by positioning the mounting set and fastening body at different locations and orientations. This spatial distribution allows the fall protection structure to provide comprehensive coverage without extending vertically in a way that would interfere with roller shutter operation
3Device complexity
If direct physical connection is used between frame fastener and fastening body, then the structure is simplified, but the installation lacks official approval due to complex statics
Solution Approach 1:
The connection path is segmented into distinct fastening stages: frame fasteners attach the mounting set to the frame, and separate fastening elements attach the fastening body to the frame. This segmentation creates clearly defined load paths and attachment points that can be independently verified for compliance with structural approval standards
Solution Approach 2:
The frame acts as an intermediary that mediates the force transmission between the mounting set and the fastening body. This indirect connection through the frame creates a more transparent statics model with clearly defined load paths, making it easier to verify compliance with structural approval requirements compared to a direct rigid connection
