Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single controller executes identification based on sensing results from both standard and removable sensor units, then basic identification function is maintained, but the controller may fail to respond to new removable units and fail to meet country-specific requests
Solution Approach 1:
The patent divides the identification system into a standard identifier with a standard controller and a further identifier with a second controller. The standard controller handles basic identification tasks while the second controller专门 handles expansion functions from removable sensor units. This segmentation allows each controller to specialize in specific functions, improving both adaptability to new sensor types and reliability of control responses.
2Adaptability or versatility
If multiple sensors are mounted to meet country-specific requests, then identification coverage is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal identification system where the standard identifier provides basic functionality and the option attachment member with further identifiers enables expansion to meet various country-specific requirements. The system can universally accommodate different sensor types (ultrasonic, optical, magnetic, capacitive) through standardized interfaces, reducing the need for completely different device configurations for different countries.
3Area of stationary object
If the further identifier is attached close to the standard identifier, then space is saved, but noise interference increases and detection precision decreases
Solution Approach 1:
The patent applies local quality by positioning the further identifier at a specific location (apart from the standard identifier) that optimizes detection precision for security characteristics. This spatial arrangement reduces noise interference between different sensor units while still maintaining compact overall device structure. The positioning strategy prioritizes measurement quality in the detection zone.
4Reliability
If security characteristics and damages are detected with difficulty, then identification reliability is compromised, but adding specialized sensors increases device complexity
Solution Approach 1:
The patent enables the system to self-adapt to different detection requirements through the removable further identifier configuration. The standard identifier provides baseline detection capability, while the optional further identifier with specialized sensors (ultrasonic, optical, magnetic, capacitive) can be attached as needed to detect specific security characteristics and damages. This self-service approach allows the system to maintain reliability for different detection tasks without permanently increasing complexity.
