Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration of camera settings is used with ALS and filters, then system complexity is reduced, but productivity and detection efficiency deteriorate due to time-consuming manual adjustments
Solution Approach 1:
The system automatically detects filter presence using sensors and self-configures camera settings without manual intervention. The processor receives sensor data indicating which filters are present and automatically adjusts camera parameters accordingly, enabling the system to serve itself and eliminating time-consuming manual configuration steps
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor filter presence and provide data to the processor, which then adjusts camera settings in real-time. This closed-loop control ensures the camera is always optimally configured based on the current filter configuration, maintaining high detection efficiency
2Measurement precision
If integrated automated system with sensors is implemented, then productivity and measurement precision are improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single platform: the ALS provides illumination, sensors detect filter presence, the processor analyzes data and makes decisions, and the camera captures images. This multi-functional integration ensures that all components work together seamlessly to improve detection accuracy while managing system complexity through unified design
Solution Approach 2:
The system replaces manual mechanical adjustment of camera settings with an automated electronic control system. Sensors electronically detect filter presence and the processor automatically adjusts camera parameters through electronic interfaces, eliminating the need for manual mechanical configuration and improving both precision and efficiency
3Adaptability or versatility
If multiple filters and camera settings are manually adjusted, then adaptability to different foreign materials is improved, but loss of time increases due to repetitive manual configuration
Solution Approach 1:
The system pre-configures multiple filter options and corresponding camera settings in its database. When a filter is detected, the processor retrieves the pre-determined optimal settings from memory and applies them automatically, eliminating the need for time-consuming manual configuration while maintaining adaptability to different foreign materials
Solution Approach 2:
The system dynamically adjusts camera settings based on real-time sensor input about filter presence. Rather than static manual configuration, the system continuously adapts its parameters (shutter speed, gain, exposure) according to the current optical configuration, enabling versatile detection across different materials without repetitive manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient and non-destructive detection and documentation of biological evidence, such as semen, saliva, and urine, by enhancing visibility and capturing high-quality images.
Implementation Method 1
Fluorescence happens when the ALS emitted to the biological evidence, such as semen, saliva and urine, and these fluids absorb light at a particular wavelength and then re-emit the absorbed energy as light at a different (i.e., longer) wavelength
Implementation Method 2
Biological evidence can be detected by forensic light source due to their natural characteristics, such as light absorption (blood) or fluorescence effect (semen, saliva and urine)
