Variable Density Blasting Mat Using Local Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blasting mats are heavy and cumbersome due to uniform density, making them difficult to move and position effectively after use, leading to unnecessary costs and inefficiencies in material handling and usage.
Innovation Solution
A blasting mat with regions of varying densities, achieved by applying different compression pressures to resilient elements such as tire segments, allowing for a more dense central region to effectively limit ground movement while reducing overall weight and improving mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform density is used throughout the blasting mat, then sufficient weight is achieved for effective blanketing, but the mat becomes heavy and difficult to move
Solution Approach 1:
The blasting mat is divided into regions with different densities: a first region with higher density material (truck tire portions) and a second region with lower density material (automobile tire portions). This local differentiation allows the mat to achieve sufficient weight for effective blanketing in critical areas while reducing overall weight for easier handling and mobility.
2Ease of manufacture
If uniform material types are used throughout the blasting mat, then manufacturing is simplified, but unnecessary costs are incurred in material purchase and handling
Solution Approach 1:
Different regions of the blasting mat use different material types optimized for their specific functions. The first region uses truck tire portions which are more dense and effective for ground coverage, while the second region uses automobile tire portions which are lighter. This targeted material selection reduces overall material costs while maintaining manufacturing feasibility through standardized assembly processes.

Function Achieved in This Case
The blasting mat effectively limits ground movement during blasts while being lighter and easier to move, reducing costs and handling inefficiencies by optimizing material distribution and density.
Implementation Method 1
The resilient elements in each region are respectively subjected to a preselected compression pressure to cause each region to have a respective preselected density

AI summary
A blasting mat including a number of resilient elements arranged in a number of parallel rows that are located in a number of predetermined regions of the blasting mat. The resilient elements in each region are respectively subjected to a preselected compression pressure, to cause each region to have a respective preselected density within a range of preselected densities. The preselected density of at least a second selected one of the regions is greater than the preselected density of at least a first selected one of the regions.
