Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a continuous demand for cost-effective lubricant compositions with improved characteristics for industrial applications, particularly in the automotive, tractor, airline, and railroad industries, where existing lubricants often fall short in terms of performance and environmental sustainability.
Innovation Solution
The development of compositions comprising farnesane dimers and/or farnesene dimers combined with squalane, squalene, and dehydrosqualene, which offer enhanced lubricity, biodegradability, low toxicity, and suitability for use in environmentally sensitive areas, including marine ecosystems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lubricants are used to provide basic lubrication, then lubrication function is achieved, but environmental sustainability and performance characteristics are insufficient
Solution Approach 1:
The patent changes the chemical composition parameters by using farnesane dimers and farnesene dimers as base oils with specific molecular structures (C20 isoprenoid compounds). These parameter changes result in improved biodegradability, reduced toxicity to aquatic organisms, and enhanced viscosity index while maintaining lubrication performance
Solution Approach 2:
The patent creates composite lubricant compositions by combining farnesane dimers and/or farnesene dimers with specific additive packages including viscosity index improvers, anti-wear agents, and antioxidants. This composite approach achieves both environmental sustainability and improved performance characteristics simultaneously
2Reliability
If lubricant compositions are developed for improved performance, then viscosity index and lubricity are enhanced, but complexity of formulation increases
Solution Approach 1:
The patent achieves high viscosity index (above 100) by changing the fundamental base oil parameter from conventional mineral oils to farnesane/farnesene dimers. This single parameter change in base oil selection provides inherent viscosity stability across temperature ranges, reducing the need for complex additive packages to achieve the same effect
3Object-affected harmful factors
If environmentally friendly lubricants are used to reduce harm to aquatic organisms, then biodegradability improves, but lubrication performance may be compromised
Solution Approach 1:
The patent changes the chemical structure parameters of the base oil to C20 isoprenoid compounds (farnesane and farnesene dimers) which have inherent biodegradability and low toxicity to aquatic organisms. Despite these environmentally friendly parameter changes, the molecular structure maintains excellent lubrication performance through appropriate viscosity and film-forming properties
Solution Approach 2:
The patent formulates composite compositions combining the environmentally benign farnesane/farnesene dimer base oils with performance-enhancing additives. This composite approach ensures that biodegradability and ecological safety are maintained while lubrication performance meets industrial application requirements
