Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional barcode decoding devices use fixed scan units, then the device structure is simple, but the device cannot adjust decoding direction based on barcode direction
Solution Approach 1:
The barcode decoding device automatically identifies barcode direction and adjusts scan coordinates without external intervention. The direction identification module detects barcode orientation and the scan coordinate generation module self-adjusts scanning parameters, enabling the system to serve itself rather than requiring manual configuration.
Solution Approach 2:
The scan coordinate generation module dynamically adjusts scan coordinates based on detected barcode direction. Instead of fixed scan lines, the system generates adaptive scan coordinates that rotate and reposition according to the barcode's actual orientation, transforming a static scanning system into a dynamic one.
2Measurement precision
If conventional devices use fixed scan lines, then the scanning process is simple, but the devices cannot correctly identify bar space information of barcodes with various orientations
Solution Approach 1:
The system transforms fixed scan lines into dynamic scan coordinates that adapt to barcode orientation. The scan coordinate generation module calculates rotated and repositioned scan coordinates based on detected barcode direction, enabling accurate bar space identification regardless of barcode rotation angle.
Solution Approach 2:
The system changes scanning parameters (coordinate system orientation, scan line angles) based on detected barcode direction. By dynamically adjusting these parameters, the system maintains high measurement precision for bar space information across various barcode orientations without requiring physical hardware changes.
3Ease of operation
If manual adjustment of scan direction is required, then the decoding device structure is simple, but the ease of operation deteriorates
Solution Approach 1:
The barcode decoding device performs automatic direction identification and scan coordinate adjustment without user intervention. The direction identification module detects barcode orientation and the scan coordinate generation module automatically reconfigures scanning parameters, making the system self-sufficient and eliminating manual operation requirements.
Solution Approach 2:
The system implements a feedback loop where the direction identification module continuously monitors barcode orientation and feeds this information back to the scan coordinate generation module, which then adjusts scanning parameters accordingly. This closed-loop control enables automatic adaptation to various barcode orientations.
