Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time analysis on vibration signal is performed to determine oil injection time, then lubricant consumption can be determined, but computing resources required and hardware cost increase
Solution Approach 1:
The patent extracts the essential operational parameters (operational speed, actuation information) from the complex vibration signal analysis approach. Instead of analyzing the entire vibration signal in real-time, the method extracts only the necessary parameters that correlate with lubricant consumption, thereby reducing computational resources and hardware requirements while maintaining measurement precision.
Solution Approach 2:
The patent replaces the mechanical vibration analysis system with a computational model-based approach. Instead of using vibration sensors and real-time signal processing hardware, the method uses predetermined models that calculate lubricant consumption based on operational parameters, substituting complex mechanical measurement systems with simpler computational calculations.
2Measurement precision
If vibration sensor and real-time analysis are used, then lubricant consumption can be monitored, but computing resources increase
Solution Approach 1:
The patent performs preliminary actions by establishing predetermined models and relationships between operational parameters and lubricant consumption before actual monitoring begins. These models are prepared in advance, allowing the system to calculate lubricant consumption using simple look-up tables or pre-computed formulas during operation, rather than performing complex real-time analysis that would consume significant computing resources.

AI summary
A method for determining lubricant consumption by a transmission mechanism disposed on a machine tool includes steps of: a) estimating, based on an operational speed and a predetermined first predictive model, a total operational physical quantity; b) estimating, based on an individual operational physical quantity and the total operational physical quantity, a total operational count; c) receiving actuation information from the machine tool, and calculating a partial operational count based on the actuation information; and d) calculating, based on the partial operational count and the total operational count, a ratio between an amount of lubricant consumption within a time period and a total amount of lubricant.
