Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera-based visual detection system is implemented for user identification, then security and detection quality are improved, but device complexity and costs increase
Solution Approach 1:
The camera is designed to perform multiple functions: it serves both as a camera for visual detection of body parts and as a lighting device that can project light patterns. This multi-functionality reduces the need for separate components, thereby lowering device complexity while maintaining high detection quality through the camera's primary function
Solution Approach 2:
A light projector is introduced as an intermediary component that projects light patterns onto the user's body part before camera detection. This intermediary element enhances the detection quality by improving contrast and visibility of biometric features, while the patterned light approach maintains system simplicity by using a single projector rather than multiple complex illumination sources
2Measurement precision
If multiple separate components are used for camera detection and lighting, then detection quality is improved, but structural complexity and space requirements increase
Solution Approach 1:
The camera and lighting device are merged into a single integrated unit. The camera housing incorporates the light projector, allowing both detection and illumination functions to be performed from the same spatial location. This merging reduces the overall system footprint and eliminates the need for separate mounting spaces for independent camera and lighting components
Solution Approach 2:
The integrated camera unit serves dual purposes: it captures images for biometric detection and simultaneously provides structured light illumination. This multi-functional design eliminates redundant components and reduces the total space required compared to separate camera and lighting systems
3Reliability
If a camera is dedicated solely to body part detection, then detection reliability is improved, but device versatility and cost-effectiveness worsen
Solution Approach 1:
The camera system is designed to perform multiple vehicle functions beyond just body part detection. It can detect various body parts for different access methods, work in conjunction with the lighting device for enhanced detection under different lighting conditions, and potentially serve other vehicle functions, thereby improving versatility while maintaining detection reliability through its primary detection capability
Solution Approach 2:
The system dynamically switches between different operational modes: the camera can focus on detecting different body parts (hand, face, eye) depending on the triggering signal, and the lighting device can activate or deactivate based on detection needs. This dynamic adaptability allows a single system to handle multiple detection scenarios, improving versatility without compromising reliability
