Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete methods are used to produce road kerbs and edgings, then structural strength and durability are achieved, but the production process becomes complex, costly, and time-consuming with significant environmental impact
Solution Approach 1:
The invention changes the material parameters from traditional concrete to elastomeric asphalt conglomerate, which allows the material to be applied in a viscous state and then solidify, eliminating the need for complex formworks, steel reinforcement, and multi-step concrete pouring processes while maintaining structural strength
Solution Approach 2:
The invention uses a composite material composition consisting of elastomeric material (such as rubber granulates) combined with asphalt binder, creating an elastomeric asphalt conglomerate that provides both structural integrity and flexibility, resolving the contradiction between strength and process simplicity
2Stability of the object's composition
If traditional concrete methods are used to produce road kerbs and edgings, then structural stability is achieved, but installation time and traffic disruption increase
Solution Approach 1:
The elastomeric asphalt conglomerate is prepared in advance in a viscous state, allowing it to be directly applied to the road surface and immediately form a stable structure upon solidification, eliminating the lengthy curing time required for concrete while maintaining structural stability
Solution Approach 2:
The invention utilizes the phase transition of the elastomeric asphalt conglomerate from a viscous liquid state during application to a solid state upon cooling, enabling rapid installation without formworks and with immediate structural stability, significantly reducing installation time compared to concrete methods
3Duration of action of stationary object
If traditional concrete methods are used to produce road kerbs and edgings, then material durability is achieved, but environmental impact and disposal costs increase
Solution Approach 1:
The invention employs asphalt material that can be easily removed and reused or recycled, eliminating the need for complex concrete separation processes and reducing disposal costs, while the elastomeric components can also be recovered and reused, significantly reducing environmental impact
Solution Approach 2:
The invention converts the typically harmful asphalt material, which requires disposal when removed, into a beneficial reusable resource by combining it with elastomeric material, creating a composite that maintains durability while enabling easy recovery and recycling, thus reducing environmental impact
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method allows for rapid, cost-effective installation of road kerbs with improved durability and reduced environmental impact, as the elastomeric asphalt composition is compatible with existing asphalt, enabling direct on-site production and easy recycling.
Implementation Method 1
The elastomeric asphalt conglomerate comprises a first material based on an asphalt conglomerate, obtained by removing the upper layer of an asphalt road, and a second material based on elastomeric material
Implementation Method 2
receive the first material and the second material, heat the asphalt conglomerate and the elastomeric bituminous material, thus bringing them to a liquid/semi-liquid state and mix the asphalt conglomerate and the elastomeric bituminous material
