Modular Safety Net Attachment System with Premounted Support Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety net attachment systems for construction sites are time-consuming and difficult to use, often relying on ropes or traditional mounting devices that are dependent on the shape and accessibility of construction elements.
Innovation Solution
A two-part attachment system comprising a holding unit with a U-shaped hitching element and a support unit, where the support unit is premounted on construction elements, allowing for quick and simple installation of the safety net by hitching the holding unit onto the support unit, with a U-shaped hitching element distributing the load and preventing slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ropes or mounting devices are used to secure safety nets, then the safety net can be attached to construction elements, but the mounting process becomes time-consuming and difficult
Solution Approach 1:
The attachment system is divided into separate modular components: support units that are premounted to construction elements, and holding units that attach to the support units. This segmentation allows the support units to be installed in advance, creating ready-to-use anchorage points that significantly reduce the time required for safety net installation while maintaining secure attachment through the modular connection mechanism
Solution Approach 2:
The support units are premounted onto construction elements before the safety net installation process begins. This preliminary action creates pre-positioned anchorage points throughout the construction area, eliminating the need to perform mounting operations during the actual safety net installation, thereby dramatically reducing mounting time while ensuring reliable attachment points are available
2Reliability
If traditional mounting devices are used, then safety nets can be secured, but the system becomes difficult to operate and install
Solution Approach 1:
By dividing the system into premounted support units and attachable holding units, the installation process is simplified into straightforward steps: attach the holding unit to the pre-installed support unit, then connect the safety net to the holding unit. This modular approach eliminates complex traditional mounting procedures while maintaining secure attachment through the specialized hitching element design
Solution Approach 2:
The support units act as intermediary elements between the construction elements and the holding units. These intermediaries provide standardized, pre-positioned attachment points that simplify the connection process, allowing holding units to be quickly attached without direct engagement with the construction elements themselves, thereby improving ease of operation while ensuring reliable force transmission
3Reliability
If mounting hooks are dependent on the shape and accessibility of construction elements, then they can engage with the elements, but the adaptability to different construction scenarios is limited
Solution Approach 1:
The support units are designed with universal engagement capabilities that allow them to be mounted on various types of construction elements regardless of shape or accessibility. The standardized support unit design with its specific engagement features can be attached to different construction elements, and the holding units can then be attached to any support unit, creating a universal attachment system that adapts to diverse construction scenarios while maintaining stable engagement through the specialized hitching element geometry

AI summary
This invention relates to an attachment system for securing a safety net to a support surface. The attachment system comprises a holding unit 110 comprising at least one attachment portion 111 arranged for receiving at least a portion of the safety net, and a support unit 120 arranged for engaging with the support surface. The holding unit is adapted to engage with the support unit by means of a hitching element. Thus, the attachment system of the present invention is provided as a two part system, in which the support unit may advantageously be premounted onto construction elements to provide possible anchorage points for the safety net. When a safety net is required, as preferably a number of support units are already premounted to provide possible anchorage points for the safety net, holding units are hitched onto to selected support units in a very quick and simple manner. The safety net is then mounted onto the attachment portions of the holding units.
