Engineering Contradiction Analysis
1Use of energy by moving object
If molybdenum compounds are used as friction modifiers, then fuel economy and antiwear properties are improved, but cost increases and other performance characteristics deteriorate
Solution Approach 1:
The patent replaces expensive molybdenum compounds with cheaper organic friction modifiers that achieve comparable fuel economy benefits. The formulation uses multiple affordable additives working synergistically to provide the same functional outcome without the high cost associated with molybdenum-based solutions.
Solution Approach 2:
The patent creates a composite additive system combining organic friction modifiers, ZDDP antiwear agents, and detergent packages that collectively deliver the performance previously achieved by single-component molybdenum compounds. This multi-component approach achieves fuel economy improvement while avoiding the cost and performance trade-offs of molybdenum additives.
2Ease of operation
If molybdenum compounds are used as friction modifiers, then boundary friction characteristics are improved, but adverse effects on other performance characteristics occur
Solution Approach 1:
The patent employs a multi-functional additive package where organic friction modifiers provide boundary lubrication, ZDDP contributes antiwear and extreme pressure protection, and detergent components maintain engine cleanliness. This universal additive system delivers comprehensive performance across multiple protection categories without the adverse effects associated with molybdenum compounds.
Solution Approach 2:
The patent modifies the chemical composition parameters by substituting molybdenum-based compounds with organic alternatives having different molecular structures and mechanisms of action. This parameter change enables achievement of similar friction reduction while improving compatibility with other lubricant additives and maintaining broader performance characteristics.
3Ease of manufacture
If titanium compounds are used to replace molybdenum compounds, then cost is reduced and performance is maintained, but formulation complexity increases
Solution Approach 1:
The patent merges titanium compounds with existing lubricant additive packages including ZDDP, organic friction modifiers, and detergents into a unified formulation system. This integration achieves cost reduction through titanium substitution while managing formulation complexity through synergistic interactions between components that simplify the overall additive package design.

AI summary
A process for the production of aerated frozen products by preparing a mixture of ingredients suitable for a frozen aerated product, adding an emulsifier mixture, aerating the mix to obtain an aerated mix having an overrun of about 20% to about 250% and about 5% to about 100% for the aerated frozen ice cream and water ice, respectively, and freezing the aerated mix to produce the aerated ice cream or water ice. The preferred emulsified is propylene glycol monostearate.
