Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual indirect methods are used to determine delay times, then measurement can be performed, but automation is difficult and complexity increases
Solution Approach 1:
The patent replaces manual indirect measurement methods with an automated vibration-based detection system. The vibration sensor detects vibrations caused by viscous fluid impacting the substrate, and the computing device automatically determines delay times by analyzing the temporal relationship between dosing device activation and vibration onset, eliminating manual intervention and enabling full automation.
Solution Approach 2:
The system uses the natural vibration signal generated by the viscous fluid impact itself as the measurement indicator. The impact of the fluid on the substrate creates inherent vibrations that serve as the detection signal, eliminating the need for external complex measurement apparatus and enabling self-measuring capability.
2Extent of automation
If vibration sensor and computing device are used, then automation is achieved, but device complexity increases
Solution Approach 1:
The vibration sensor acts as an intermediary that converts the physical impact of viscous fluid into an electrical signal that can be processed by the computing device. This intermediary enables automated detection while keeping the system architecture simple and modular.
3Manufacturing precision
If delay times are not accurately determined, then coordination of dosing device and fluid valve is poor, but application precision deteriorates
Solution Approach 1:
The system uses vibration detection as feedback to determine when the viscous fluid actually impacts the substrate. This feedback information is used by the computing device to calculate the delay time and optimize the coordination between the dosing device and fluid valve, thereby improving application precision through closed-loop control.
