Engineering Contradiction Analysis
1Object-affected harmful factors
If sulphur content is reduced to meet environmental standards, then environmental pollution is reduced, but electrical conductivity decreases leading to static charge accumulation
Solution Approach 1:
The patent introduces an intermediary substance (additive composition containing conductive materials) to transfer electrical charge between the low-sulphur fuel and earthed fuel lines/vessels. This mediator enables charge dissipation without requiring the fuel itself to have high conductivity, thus resolving the contradiction between low sulphur content and adequate electrical conductivity
Solution Approach 2:
The patent changes the electrical conductivity parameter of the fuel by adding conductive additives. The additive composition modifies the fuel's electrical properties without altering its sulphur content or combustion characteristics, allowing the fuel to meet both environmental standards and conductivity requirements
2Reliability
If conventional anti-static additives are used, then static charge release is enhanced, but additive quantity required is high and effectiveness is insufficient
Solution Approach 1:
The patent uses a composite additive composition containing multiple components including conductive materials (such as metal particles, carbon-based materials) combined with surfactants or other functional additives. This composite approach provides synergistic effects where the conductive materials enable charge transfer while other components enhance dispersion and stability, achieving effective static charge control at lower overall additive concentrations
Solution Approach 2:
The patent optimizes the conductivity parameter of the additive composition itself, creating a highly conductive additive formulation that requires smaller quantities to achieve the desired effect. By maximizing the conductivity parameter of the additive, the required amount is minimized while maintaining effectiveness
