Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multipurpose oils are volatile, flammable, and non-renewable, posing safety and environmental concerns while lacking optimal anticorrosion, water displacement, and lubricating properties, especially in hard-to-reach areas.
Innovation Solution
A multipurpose oil comprising 80.0-99.5 vol-% of a renewable hydrocarbon base stock with a biogenic carbon content of over 80 wt-%, primarily composed of C14-C20 hydrocarbons and 70 wt-% isoparaffins, combined with 0.5-20.0 vol-% of an anionic surfactant composition, particularly anionic aromatic surfactants, to enhance penetration, lubrication, and anticorrosion performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional multipurpose oils are used, then they can penetrate between surfaces and loosen stuck surfaces, but they are volatile and flammable causing safety concerns and environmental harm
Solution Approach 1:
The patent changes the chemical composition parameters by using renewable hydrocarbon base stocks with specific carbon number distributions (C15-C35, preferably C17-C29) and high paraffin content (≥80 wt-%, preferably ≥90 wt-%). This parameter change increases the flash point to ≥100°C (preferably ≥120°C) and reduces volatility through controlled boiling point ranges (T5: 200-350°C, T95: 300-450°C), thereby resolving the contradiction between penetration performance and safety
Solution Approach 2:
The patent creates a composite formulation by combining renewable hydrocarbon base stocks with specific additive packages including corrosion inhibitors, lubricity additives, and anti-wear agents. This composite approach maintains the penetration ability while the synergistic combination of components provides enhanced safety characteristics and environmental compatibility
2Reliability
If conventional multipurpose oils are applied directly on surfaces, then they can provide lubrication and corrosion protection, but most of the applied oil evaporates or drips into the environment
Solution Approach 1:
The patent optimizes viscosity parameters (kinematic viscosity at 40°C: 2-10 mm²/s, preferably 3-7 mm²/s) and boiling point distribution (T5-T95 range: 100-150°C) to reduce evaporation losses. The high flash point (≥100°C) and controlled volatility ensure that the lubricant remains on the surface longer, improving reliability while reducing environmental loss
Solution Approach 2:
The patent ensures continuous protective action by formulating the oil to remain stable and effective over extended periods. The renewable hydrocarbon base stock provides sustained lubrication and corrosion protection without rapid evaporation, maintaining a continuous protective film on surfaces
3Reliability
If conventional multipurpose oils are used, then they provide basic lubrication and corrosion protection, but they are non-renewable and not biodegradable
Solution Approach 1:
The patent fundamentally changes the origin parameter of the base stock from fossil-based to renewable biological sources (vegetable oils, animal fats, microbial oils). This parameter change ensures biodegradability and renewable sourcing while maintaining the necessary lubrication and corrosion protection properties through careful formulation
Solution Approach 2:
The patent creates an environmentally compatible composite by combining renewable hydrocarbon base stocks with biodegradable additives and corrosion inhibitors. This composite formulation achieves reliable lubrication and corrosion protection while ensuring complete biodegradability and eliminating persistent environmental pollution
4Ease of operation
If multipurpose oil has low viscosity for good fluidity, then it can flow easily to treated surfaces, but it runs and drips off quickly
Solution Approach 1:
The patent optimizes the viscosity parameter to a specific range (kinematic viscosity at 20°C: 2-10 mm²/s, at 40°C: 2-7 mm²/s) that balances fluidity and residence time. This parameter optimization ensures the oil flows easily to treat surfaces while maintaining sufficient thickness to prevent rapid running and dripping, extending the duration of protective action
