Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressure sensor is used to detect printing contact, then the printing process can be monitored, but the detection accuracy deteriorates due to sensitivity to external interference
Solution Approach 1:
The patent replaces the conventional pressure sensor (mechanical detection system) with a vibration detection system that uses a vibration transmission plate and acceleration sensor to detect printing contact through vibration signals. This substitution eliminates the sensitivity issues of pressure sensors to external interference while maintaining detection capability, thereby improving both reliability and measurement precision.
2Measurement precision
If a vibration detector with piezoelectric ceramic sheet is used, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The vibration transmission plate serves multiple functions: it transmits vibration signals from the display panel to the piezoelectric ceramic sheet, provides structural support, and acts as a mounting platform for the acceleration sensor. By combining multiple functions into a single component, the design improves detection accuracy while minimizing the increase in device complexity.
Solution Approach 2:
The piezoelectric ceramic sheet acts as an intermediary element that converts mechanical vibration from the printing contact into electrical signals that can be detected by the acceleration sensor. This intermediary conversion mechanism enables accurate detection while keeping the overall system structure relatively simple and manageable.
