Catalyst-Binder Molding of Sustainable Barriers for Faster Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming sustainable articles, such as traffic barriers from recycled tires, are slow due to the long setting time of binders and the use of atmospheric pressure molding, which reduces facility throughput and limits the tuning of physical properties.
Innovation Solution
A method involving a catalyst-enhanced binder that quickly binds waste material, such as crumb rubber, into sustainable barriers, allowing for varying densities and properties, and a connection system with loops and plates for reinforcement, enabling faster production and customizable physical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binder is used to bind recycled tires together in a mold, then the sustainable articles can be formed, but the binder takes a long time to set, increasing molding time and reducing facility throughput
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition and setting characteristics of the binder to reduce molding time. Specifically, the binder formulation is adjusted to achieve faster cure times while maintaining adequate binding strength, directly addressing the contradiction between reliable binding and high productivity.
2Ease of manufacture
If molding is performed at atmospheric pressure, then the molding process is simpler, but the molding time increases and facility throughput decreases
Solution Approach 1:
The patent changes the pressure parameter from atmospheric pressure to elevated pressure during molding. This parameter change reduces molding time and increases facility throughput while maintaining ease of manufacture through the use of standard pressure-capable molding equipment.
3Ease of manufacture
If molding is performed only at atmospheric pressure, then the process is simpler, but the physical properties of the sustainable articles cannot be tuned for specific purposes
Solution Approach 1:
The patent applies parameter changes by varying pressure, temperature, and binder composition to tune the physical properties of the sustainable articles. These parameter changes enable customization of density, strength, and other properties for specific applications while maintaining manufacturing simplicity through systematic control of these variables.
