Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection devices for roofs lack sufficient security and stability, particularly when securing heavy individuals or multiple people, and often require complex assembly processes with numerous loose components.
Innovation Solution
A fall protection device with a telescoping mounting base and a counter-clamping element featuring a U-shaped cross-section, connected by screw connections with self-locking threads, allowing secure attachment to adjacent rafters and minimizing loose components during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fall protection device is attached to a single rafter, then the installation is simple, but the holding power is insufficient for heavy individuals or multiple people
Solution Approach 1:
The fall protection device is segmented to attach to multiple adjacent rafters rather than a single rafter. The mounting base includes multiple attachment points distributed across adjacent rafters, dividing the load-bearing function among multiple structural elements. This segmentation increases holding power while maintaining installation simplicity by using standard attachment procedures on each rafter.
Solution Approach 2:
The device merges multiple attachment points on adjacent rafters into a single integrated mounting base. By combining the securing function across multiple rafters, the system achieves superior holding power comparable to heavy-duty industrial anchors while retaining the ease of installation characteristic of single-point attachments.
2Ease of manufacture
If traditional assembly methods are used with multiple loose components, then the device can be assembled, but the assembly process is complex and components may fall during assembly
Solution Approach 1:
The clamping element and counter-clamping element are merged into a single integrated component rather than separate parts. This integration eliminates the need for multiple loose components during assembly, reducing the risk of components falling while maintaining full assembly capability. The single component design simplifies the assembly process while achieving the same clamping function.
Solution Approach 2:
The mounting base is designed with nested structures where components are housed within each other during assembly. The integrated clamping mechanism nests the clamping element within the counter-clamping element, allowing assembly without loose components. This nesting approach enables complex assembly functionality while minimizing the number of separate parts that could fall during installation.
3Reliability
If the clamping element and counter-clamping element are connected with multiple screw connections, then the connection is secure, but the assembly requires many loose components
Solution Approach 1:
Multiple screw connections are merged into a single integrated fastening mechanism. The clamping element and counter-clamping element are connected through one unified screw connection that provides the same security as multiple separate connections. This reduces the number of loose components during assembly while maintaining connection reliability through the distributed attachment points on adjacent rafters.

AI summary
The invention relates, inter alia, to a fall protection device (10, 11, 12) comprising a mounting base (30), a safety element (80) connected to the mounting base (30), and a connection device (810) attached to the safety element (80), which enables mechanical coupling with an external safety means (860), in particular a rope (861) or hook (862). According to the invention, the mounting base (30) is telescopically designed and adjustable in length, and the mounting base (30) can be attached, in particular screwed, at one end to and/or on a rafter (710) of a roof (700) and at another end to and/or on an adjacent rafter (710) of the roof (700).
