Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lubricant is used in mechanical device, then friction is reduced and operation is improved, but lubricant evaporates over time and is lost
Solution Approach 1:
The patent applies preliminary action by pre-calculating the evaporation amount of lubricant using a dedicated calculation formula that considers container shape, lubricant properties, environmental conditions, and time. This allows the system to proactively determine lubricant replenishment needs before actual depletion occurs, ensuring continuous reliable operation while accounting for evaporation losses.
2Reliability
If lubricant amount is managed to prevent operation issues, then reliability is maintained, but evaporation loss is not considered in traditional management
Solution Approach 1:
The patent implements feedback by calculating the evaporation amount and using this information to adjust lubricant management decisions. The calculation results provide feedback on actual evaporation losses, enabling dynamic adjustment of lubricant replenishment timing and quantities to maintain optimal lubrication while compensating for evaporative losses.
Solution Approach 2:
The patent introduces an intermediary calculation formula that bridges the gap between traditional lubricant management and evaporation effects. This formula acts as a mediator by quantifying evaporation losses based on multiple parameters, transforming unmeasured evaporation into actionable information for improved lubricant management.
3Ease of operation
If simple lubricant management is used, then ease of operation is maintained, but evaporation effects are ignored
Solution Approach 1:
The patent applies parameter changes by introducing a multi-parameter calculation approach that considers container shape parameters, lubricant physical properties, environmental conditions, and time. This transforms the simple lubricant management approach into a more precise system that accounts for evaporation while maintaining operational ease through systematic parameter evaluation.

AI summary
This method for calculating the evaporation amount of a lubricant within a mechanical device to the exterior includes: a calculation step in which the evaporation amount of the lubricant is calculated using a calculation formula defined so as to include a container shape parameter defined by modeling the configuration within the machine device as a container in which the lubricant is accommodated, a physical property parameter of the lubricant, an environmental parameter from the area around the lubricant, and a parameter regarding time; and an output step in which the evaporation amount calculated in the calculation step is output.
