Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection methods are used between acoustic emission probe and preamplifier during high-frequency motion rubbing, then the device structure is simple, but the connection is unstable and causes data distortion
Solution Approach 1:
The patent employs a dynamic connection system where the acoustic emission probe moves with the rubbing pair surface while maintaining stable signal transmission. The probe is positioned to follow the high-frequency reciprocating motion, and the connection system adapts to the dynamic conditions through flexible wiring and stable mounting mechanisms that accommodate motion without compromising signal integrity.
Solution Approach 2:
The patent introduces an intermediary connection system between the acoustic emission probe and the preamplifier, using stable mounting structures and signal transmission pathways that isolate the probe from vibration-induced instability while maintaining electrical connection. This intermediary system acts as a buffer that preserves signal fidelity during high-frequency motion.
2Measurement precision
If stable connection is achieved during high-frequency reciprocating rubbing, then measurement accuracy is improved, but the required surface area of test sample increases
Solution Approach 1:
The patent applies local quality by concentrating the acoustic emission probe on a specific localized area of the rubbing pair surface where wear mechanisms are most active. The probe is positioned to monitor critical regions such as contact zones or areas with highest stress, enabling accurate wear mechanism detection without requiring the entire surface to be accessible or large in area.
Solution Approach 2:
The patent uses acoustic emission technology to create a signal copy or representation of the wear mechanisms occurring on the rubbing pair surface. Instead of requiring direct access to or manipulation of the entire surface, the system captures acoustic signals that replicate the wear process, allowing measurement of wear mechanisms from a limited surface area through signal analysis.
