Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricating oil compositions often lack effective corrosion control, stability under varying temperatures, and long-lasting lubricity, with some being flammable and having poor lubrication qualities.
Innovation Solution
A lubricating oil composition comprising a dearomatized hydrocarbon distillate, a post lubricant petroleum hydrocarbon, and white mineral oil, with specific ratios and properties that enhance corrosion control, stability, and lubrication, including a flash point greater than 220° F., a specific gravity of 0.8605, and a viscosity of 150 cSt, allowing for non-staining and odorless performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lubricating oil compositions are used, then basic lubrication is provided, but corrosion control is insufficient and stability under varying temperatures is poor
Solution Approach 1:
The patent employs a composite lubricating oil composition combining multiple components: dearomatized hydrocarbon distillate (15-25%), post lubricant petroleum hydrocarbon (5-15%), and white mineral oil (balance). This composite approach provides superior corrosion control and temperature stability compared to single-component oils, while the specific ratios optimize performance without excessive complexity.
Solution Approach 2:
The patent specifies precise parameter ranges including flash point greater than 220° F., specific gravity at 25° C. of 0.8605, and viscosity of 150 cSt. By controlling these parameters within defined ranges, the composition achieves reliable corrosion protection and thermal stability while maintaining manageable composition complexity.
2Duration of action of moving object
If conventional lubricating oil compositions are used, then lubrication is provided, but long-lasting lubricity is not achieved
Solution Approach 1:
The patent formulates a lubricating oil composition designed to provide continuous lubrication over extended periods. The combination of dearomatized hydrocarbon distillate and post lubricant petroleum hydrocarbon creates a stable lubricating film that maintains its properties under varying conditions, ensuring long-lasting lubricity and retention without degradation.
3Object-affected harmful factors
If conventional lubricating oil compositions are used, then lubrication is provided, but flammability occurs and safety is compromised
Solution Approach 1:
The patent addresses flammability by selecting hydrocarbon components with high flash points greater than 220° F. This converts the potential harm of flammability into a safety benefit, creating a lubricating oil that resists ignition while maintaining effective lubrication performance. The careful selection of hydrocarbon sources inherently provides fire resistance.
4Object-generated harmful factors
If conventional lubricating oil compositions are used, then lubrication is provided, but staining and odor issues occur
Solution Approach 1:
The patent formulates a lubricating oil with white mineral oil as the base component, which is known for its clean, non-staining properties and ease of removal. This component provides a temporary, non-persistent lubrication that does not stain surfaces and can be easily washed off, contrasting with traditional lubricants that leave residues.
