Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement methods are used for roller diameter, then the measurement process is simple, but the measurement precision is insufficient and cannot accurately detect diameter errors
Solution Approach 1:
The patent replaces traditional mechanical measurement methods with a laser measurement system. The laser sensor emits light to the roller surface and detects the reflected light to measure diameter, eliminating mechanical contact and achieving non-contact high-precision measurement of roller diameter errors
Solution Approach 2:
The patent introduces a laser as an intermediary between the measurement system and the roller. The laser beam serves as the measuring medium that interacts with the roller surface to obtain diameter information without direct mechanical contact, enabling precise error detection
2Reliability
If manual measurement methods are used, then the device structure is simple, but human error cannot be reduced and measurement consistency is poor
Solution Approach 1:
The measurement system performs self-measurement through automated laser scanning and data processing. The system independently completes the measurement process without human intervention, eliminating human error and ensuring consistent, reliable measurements across multiple rollers
Solution Approach 2:
The patent implements a feedback mechanism where the laser sensor continuously monitors the roller diameter and the system processes the data to provide measurement results. This closed-loop feedback ensures accurate detection and recording of diameter errors, improving measurement reliability
3Manufacturing precision
If rollers with diameter errors are used in planetary roller screws, then the manufacturing cost is lower, but the operational stability and service life are severely affected
Solution Approach 1:
The patent applies preliminary measurement and selection of rollers before they are assembled into planetary roller screws. By measuring and identifying rollers with consistent diameter dimensions in advance, the system ensures high manufacturing precision and uniformity, preventing operational instability and extending service life
