Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety nets for catching heavy loads, particularly dynamic impact bodies like rocks, lack sufficient safety and stability, often leading to damage and failure due to uneven force distribution and potential holes or gaps that allow further impacts.
Innovation Solution
A safety net design with a greater maximum total extension in the outer regions compared to inner regions, featuring interlocking net elements with additional buffer paths and optimized force distribution, including variations in shape, size, and material composition to enhance safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the safety net has uniform extension throughout, then the structure is simple and easy to manufacture, but the force distribution is uneven leading to potential failure points
Solution Approach 1:
The patent applies local quality by varying the total extension of net elements based on their position within the safety net. Net elements in the outer region have a greater maximum total extension than those in the inner region, creating localized structural differences that optimize force distribution and prevent failure at specific locations while maintaining overall structural integrity.
2Reliability
If the safety net has smaller extension throughout, then the material usage and cost are reduced, but the interception area is insufficient allowing impact bodies to pass through
Solution Approach 1:
The patent implements local quality by differentiating the extension characteristics of net elements based on their spatial location. Outer region net elements have greater maximum total extension to ensure adequate interception area and prevent impact bodies from passing through, while inner region elements have smaller extension to optimize material usage and reduce costs.
3Reliability
If the safety net has greater extension in outer regions, then the interception area is enlarged and safety is improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the safety net into distinct regions (outer region and inner region) with different net element configurations. This segmentation allows each region to be optimized independently for its specific functional requirements while maintaining overall system integrity and manageability during manufacturing and assembly.
Solution Approach 2:
The patent implements local quality by varying the maximum total extension of net elements according to their position. Net elements in the outer region have greater extension than those in the inner region, creating localized structural adaptations that enhance safety where needed while simplifying manufacturing in other areas.
4Reliability
If the safety net uses uniform net elements throughout, then the manufacturing process is simplified, but the force distribution during impact is uneven causing localized damage
Solution Approach 1:
The patent applies local quality by configuring net elements with different maximum total extensions based on their position within the safety net. This creates localized force distribution characteristics that better match the expected impact patterns, with outer region elements designed to handle edge loads and inner region elements optimized for central impact forces.

AI summary
The invention relates to a safety net, in particular for trapping heavy loads, preferably dynamic impact bodies, in particular rocks, the safety net being formed, at least to a large extent, from intermeshing net elements (10a-f). According to the invention, a maximum total extension (12a-f) of the safety net parallel to a main extension direction (14a-f) of the safety net, in an outer region (18a-f) of the safety net which comprises at least one outermost row (16a-f) of net elements (10a-f), is significantly greater than a minimum total extension (20a-f) of the safety net parallel to the main extension direction (14a-f) in an inner region (22a-f) which is different from the outer region (18a-f) of the safety net.
