Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mounting head is cleaned and air flow measurement is automated, then maintenance efficiency is improved, but detection accuracy of internal air sensors may decrease leading to inconsistent suction nozzle functionality
Solution Approach 1:
A reference air sensor is introduced as an intermediary standard device with known accurate detection characteristics. The internal air sensor's measurements are compared against this reference standard, allowing calibration and verification of detection accuracy while maintaining automated maintenance operations.
Solution Approach 2:
The system implements feedback by comparing the internal air sensor detection results with the reference air sensor detection results. When discrepancies are detected, the internal sensor can be calibrated or replaced based on the reference standard, ensuring continuous accuracy in the automated maintenance process.
2Extent of automation
If the internal air sensor is used continuously for detection, then automation is maintained, but detection accuracy decreases over time requiring calibration
Solution Approach 1:
The reference air sensor is pre-configured with known accurate detection characteristics before the automated maintenance process begins. This preliminary setup establishes a reliable standard against which the internal sensor can be periodically compared and calibrated, maintaining automation while ensuring accuracy.
Solution Approach 2:
Continuous feedback is implemented by periodically comparing internal sensor readings with the reference sensor. This feedback mechanism triggers calibration actions when detection accuracy drift occurs, allowing the automated system to self-correct and maintain precision over time.

AI summary
A mounting head maintenance device includes an external flow path to communicate with an internal flow path of a mounting head, the mounting head having a nozzle holding section that detachably holds a suction nozzle, the internal flow path that selectively supplies negative pressure air and positive pressure air to the held suction nozzle, and an internal air sensor that is provided in the internal flow path and detects at least one of a flow rate and pressure of the air, a reference air sensor in the external flow path and configured to detect at least one of the flow rate and the pressure of the air, and a detection result acquiring section to acquire an internal detection result of the internal air sensor and a reference detection result of the reference air sensor which can be compared with the internal detection result in association with each other.
