Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pressure sensor moves on an imaginary plane to measure ejection pressure, then the jet center position can be judged, but the measurement process is time-consuming and lacks accuracy in determining impact force distribution
Solution Approach 1:
The measurement plane is segmented into multiple discrete detector positions arranged in a lattice pattern. Instead of moving a single sensor continuously, multiple fixed detectors simultaneously capture impact force data at different locations, enabling parallel measurement that reduces time while maintaining spatial distribution accuracy.
Solution Approach 2:
The mechanical moving pressure sensor system is replaced with a static array of impact force detectors. The continuous mechanical scanning process is substituted by simultaneous electronic detection across multiple fixed points, eliminating mechanical movement time and improving measurement speed and accuracy.
2Productivity
If conventional pressure sensors are used to measure ejection pressure, then jet center position can be determined, but the system cannot quickly and accurately measure impact force distribution
Solution Approach 1:
The measurement system is divided into multiple independent detector units positioned at specific lattice points. Each detector independently measures impact force at its location, allowing simultaneous data collection across the entire measurement plane, which improves both evaluation speed and the ability to map impact force distribution accurately.
Solution Approach 2:
The measurement approach transitions from one-dimensional linear scanning to two-dimensional lattice array detection. This dimensional expansion allows simultaneous measurement across the entire impact area, providing comprehensive impact force distribution data that improves both productivity and measurement precision.
3Reliability
If a single pressure sensor is used, then the device structure is simple, but it cannot accurately determine nozzle adaptability and detect issues like clogging or wear
Solution Approach 1:
The evaluation system is segmented into multiple detector positions that independently measure impact force at different locations. This segmentation enables comprehensive assessment of jet flow characteristics, allowing reliable detection of nozzle issues such as clogging or wear through analysis of impact force distribution patterns across the lattice array.
Solution Approach 2:
The lattice array of impact force detectors serves multiple functions simultaneously: measuring impact force distribution, determining jet center position, evaluating nozzle adaptability, and detecting abnormalities like clogging or wear. This multi-functionality increases reliability without requiring separate specialized devices for each measurement task.
