Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tire industry faces challenges in replacing petrochemical-based materials with sustainable alternatives due to the complex structure and high production costs of waste biomass materials, particularly in creating eco-friendly tire compositions that maintain similar properties to conventional tire rubber compositions.
Innovation Solution
A method is developed to manufacture a tire rubber composition by extracting oil, free fatty acids, and phenols from lipid-based biomass using a solvent mixture, followed by carbonizing residual solids to produce carbon black, which can replace conventional petrochemical-based components like carbon black, processing oils, and anti-aging agents, and integrating these into raw rubber.

Engineering Contradiction Analysis
1Object-affected harmful factors
If waste biomass materials are used to replace petrochemical-based tire compositions, then sustainability and eco-friendliness are improved, but production cost increases due to complex processing requirements
Solution Approach 1:
The patent combines multiple extraction steps into a single solvent extraction process that simultaneously recovers oil, free fatty acids, and phenols from spent coffee grounds. This integrated approach reduces the number of processing steps and lowers production costs while maintaining sustainability benefits.
Solution Approach 2:
The extracted components (oil, free fatty acids, phenols) from spent coffee grounds are utilized for multiple purposes in tire rubber composition: oil as processing oil, free fatty acids as anti-aging agents, and phenols as reinforcing agents. This multi-functional utilization maximizes the value of the biomass material and reduces overall production costs.
2Manufacturing precision
If complex processing is applied to extract components from lipid-based biomass, then material purity and performance are improved, but energy consumption increases
Solution Approach 1:
The patent uses solvent extraction to selectively remove and separate the desired components (oil, free fatty acids, phenols) from spent coffee grounds in a single step. This extraction approach achieves high material purity without requiring multiple complex processing steps, thereby reducing energy consumption.
Solution Approach 2:
The patent optimizes extraction parameters such as solvent type, temperature, and extraction time to achieve maximum recovery of valuable components with minimal energy input. By carefully controlling these parameters, the process achieves high purity extraction while maintaining low energy consumption.
3Productivity
If multiple separate processing steps are used to recover different components, then component recovery efficiency is improved, but process complexity increases
Solution Approach 1:
The patent merges the recovery of oil, free fatty acids, and phenols into a single solvent extraction operation. This unified process achieves efficient recovery of all three components simultaneously without requiring separate processing steps for each component, thereby reducing process complexity while maintaining high recovery efficiency.
Solution Approach 2:
The single extraction process is designed to universally recover multiple different components (oil, free fatty acids, phenols) from the spent coffee grounds in one operation. This multi-functional extraction approach simplifies the overall process while ensuring efficient recovery of all valuable components for subsequent use in tire rubber composition.
