Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a remaining LC detecting sensor is disposed near the bottom of the LC bottle to detect remaining LC quantity, then the detection function is provided, but the detection is interrupted by the color of the LC bottle and variable sensor positioning causing wrong detection results
Solution Approach 1:
A transparent detecting zone is introduced as an intermediary component between the sensor and the LC bottle. This detecting zone allows the sensor to accurately detect remaining LC quantity without being interrupted by the colored bottle body, ensuring reliable detection results regardless of bottle color or sensor positioning variations.
2Ease of manufacture
If the LC bottle body is colored or non-transparency to protect or identify, then the bottle structure is simplified, but the sensor cannot detect remaining LC quantity accurately from the outside
Solution Approach 1:
The LC bottle is segmented into distinct functional zones: a colored/non-transparent body portion for protection and identification, and a transparent detecting zone for accurate sensor detection. This segmentation allows each zone to fulfill its specific function without compromising the other, maintaining both structural simplicity and detection accuracy.
3Loss of substance
If multiple LC bottles are collected and retrieved in one LC bottle for reuse, then LC utilization efficiency is improved, but the replacing frequency increases and production capacity is affected
Solution Approach 1:
The accurate remaining LC quantity detection system provides real-time feedback on LC levels in the container. This enables precise monitoring that allows for timely replacement of LC containers, optimizing the balance between LC utilization efficiency and production continuity, thereby minimizing both waste and productivity impact.
4Ease of operation
If the relative position of the remaining LC detecting sensor with respect to the LC bottle is changed, then the sensor can be positioned for detection, but the detection result becomes wrong due to position sensitivity
Solution Approach 1:
The transparent detecting zone is created as a specific local area with optimized optical properties. This local quality enhancement ensures that regardless of the sensor's exact position within the acceptable range, accurate detection is maintained because the detecting zone provides consistent optical transmission characteristics.
