Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bitumen modification technologies are used, then bitumen performance can be improved, but storage stability and elastic properties remain insufficient
Solution Approach 1:
The patent applies composite materials by combining bitumen with 2G-bioethanol industry waste lignin, elasticity modifying agents, and reactive components. This creates a modified bitumen composition that integrates the storage stability benefits of conventional bitumen modification with the elastic properties enhancement from lignin and elasticity modifiers, resolving the contradiction between storage stability and elastic properties.
Solution Approach 2:
The patent utilizes parameter changes by incorporating reactive components that undergo chemical reactions to modify the bitumen's molecular structure. These reactions change the chemical parameters of the bitumen, improving both storage stability and elastic recovery properties through controlled chemical transformations.
2Ease of manufacture
If 2G-bioethanol industry waste lignin is utilized, then production costs increase, but environmental sustainability improves
Solution Approach 1:
The patent converts the harmful waste product (2G-bioethanol industry waste lignin) into a beneficial bitumen modifier. By incorporating this waste material into bitumen modification, the patent transforms an environmental hazard into a resource that improves both economic viability and environmental sustainability, addressing the contradiction between production costs and environmental impact.
Solution Approach 2:
The patent applies discarding and recovering by recovering the 2G-bioethanol industry waste lignin from the waste stream and reusing it in bitumen modification. This recovery process prevents the waste from being discarded as useless material, instead utilizing it to create value-added bitumen products while reducing overall waste.
3Reliability
If additional transformations are applied to waste lignin, then bitumen performance improves, but production complexity and costs increase
Solution Approach 1:
The patent applies self-service by utilizing the waste lignin in its original form without requiring additional transformations or processing steps. The waste lignin directly serves as a bitumen modifier, eliminating the need for complex pre-treatment processes and reducing production complexity while maintaining improved bitumen performance.
Solution Approach 2:
The patent applies taking out by extracting and using the waste lignin directly from the 2G-bioethanol industry waste stream without further processing. This extraction approach simplifies the production process by avoiding additional transformation steps while still achieving the desired bitumen performance enhancement.
