Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic barriers are made of non-sustainable materials like concrete, which are not customizable in terms of material density and shape, prone to breaking, and lack flexibility, making them unsuitable for various applications and environments.
Innovation Solution
Sustainable barriers formed from waste materials like recycled tires, bound with a polyurethane binder and catalyst, allowing for tailored density and shape configurations to suit specific uses, with embedded connectors for reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete materials are used for barriers, then structural strength is achieved, but sustainability and environmental friendliness deteriorate
Solution Approach 1:
The patent uses composite materials made from recycled rubber particles (from waste tires) bound together with polyurethane adhesive to create barrier structures. This composite approach allows the barrier to achieve sufficient structural strength while being environmentally sustainable and reusable, directly resolving the contradiction between traditional concrete strength and sustainability.
2Ease of manufacture
If uniform density material is used throughout the barrier, then manufacturing simplicity is maintained, but adaptability to specific uses deteriorates
Solution Approach 1:
The patent enables local quality variation by allowing different densities and compositions of recycled rubber particles in different sections of the barrier. Contractors can order barriers with dense cores for structural support and less dense skins for impact absorption, or customize the entire barrier density based on specific application requirements, while still using the same basic manufacturing process.
3Productivity
If predetermined barrier shapes are manufactured, then production efficiency is maintained, but adaptability to different situations deteriorates
Solution Approach 1:
The patent implements dynamics by making the barrier shape and configuration adjustable rather than fixed. The modular design with customizable dimensions and the ability to vary material distribution allow the same manufacturing system to produce different barrier shapes and densities on demand, adapting to various application requirements without sacrificing production efficiency.
4Stability of the object's composition
If monolithic material composition is used, then material consistency is maintained, but ability to tailor properties for specific uses deteriorates
Solution Approach 1:
The patent applies local quality by enabling different material compositions and densities in different regions of the barrier. The polyurethane-bound recycled rubber composite can be formulated with varying particle sizes, densities, and concentrations in different sections, allowing optimization for specific functions such as impact absorption zones versus structural support zones.
