Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the channel is opened from time to time for cleaning, then deposits can be removed from the sensor means, but the cleaning process is very time-consuming and reduces operating time
Solution Approach 1:
The cleaning device is self-contained within the sensor carrier, allowing the measuring apparatus to clean itself without external intervention or disassembly. The wiper element can be moved into position and activated to remove deposits from the measuring window while the apparatus remains assembled and operational.
Solution Approach 2:
The cleaning device with the wiper element is integrated inside the sensor carrier, nested within the existing structure. The wiper element can be positioned inside the fluid channel and brought into contact with the measuring window without removing any components from the apparatus.
2Object-generated harmful factors
If the channel is opened for cleaning, then deposits can be removed, but the disassembly process is complex and time-consuming
Solution Approach 1:
The cleaning function is integrated into the sensor carrier structure, enabling self-cleaning without requiring the channel to be opened or disassembled. The wiper element is guided within the existing sensor carrier boundaries and operates autonomously to remove deposits.
Solution Approach 2:
The cleaning device is merged with the sensor carrier structure, combining the measuring and cleaning functions within a single integrated unit. This eliminates the need for separate cleaning operations and complex disassembly procedures.
3Ease of operation
If a wiper element is used to clean the measuring window, then cleaning can be performed in situ, but the wiper element must be precisely positioned and guided
Solution Approach 1:
The wiper element is guided along the longitudinal axis of the fluid channel, utilizing the existing dimensional space within the sensor carrier. This longitudinal guidance approach leverages the natural geometry of the channel rather than requiring complex lateral positioning mechanisms.
Solution Approach 2:
The wiper element is designed to be movable along the longitudinal axis, allowing dynamic positioning to reach different areas of the measuring window. This dynamic capability enables flexible cleaning coverage without requiring a complex fixed positioning system.
