Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional metal license plates with raised letters are used, then manufacturing simplicity is maintained, but visibility during dark hours deteriorates
Solution Approach 1:
The patent employs reflective paint and special color lights on the license plate to enhance visibility during dark hours. The reflective material changes its optical properties by reflecting light back to the source, making the plate visible without active illumination, thus resolving the contradiction between visibility improvement and structure complexity.
Solution Approach 2:
The patent replaces traditional mechanical raised letters with LED strips that display alphanumeric information dynamically. This substitution of mechanical structure with electronic display components enables enhanced visibility through programmable lighting patterns while maintaining a flat plate structure, resolving the contradiction between visibility and structural simplicity.
2Productivity
If police manually check vehicle information after arrest, then equipment simplicity is maintained, but law enforcement efficiency deteriorates
Solution Approach 1:
The license plate system performs self-identification by automatically transmitting vehicle information to law enforcement devices. The plate's embedded transmitter actively provides vehicle registration data without requiring manual input from police officers, enabling continuous tracking and instant information retrieval, thus dramatically improving law enforcement efficiency while the system handles the complexity internally.
Solution Approach 2:
The system establishes a feedback loop where the license plate continuously transmits vehicle information to law enforcement devices, and the system adjusts its transmission based on detection status. This automated feedback mechanism eliminates manual checking and enables real-time monitoring, resolving the contradiction between enforcement efficiency and system complexity.
3Loss of information
If no real-time tracking system is implemented, then system simplicity is maintained, but ability to locate vehicles deteriorates
Solution Approach 1:
The patent replaces manual location tracking with an automated electronic system where the license plate contains a transmitter that continuously broadcasts vehicle identification and location data. This electronic substitution enables real-time tracking capabilities while the plate's integrated circuitry manages the complexity of continuous transmission and data management.
4Loss of information
If LED strips and display units are added to license plate, then visibility and information accessibility are improved, but manufacturing complexity increases
Solution Approach 1:
The license plate integrates multiple functions including display unit, LED strips for illumination, wireless transmitter, and receiver capabilities into a single device. This multi-functionality approach consolidates what would otherwise be separate components, enabling enhanced information accessibility while managing manufacturing complexity through integrated design where one assembly serves multiple purposes.
Solution Approach 2:
The patent combines the display unit, LED strips, circuit board, transmitter, and receiver into a single integrated license plate assembly. By merging these components into one unified structure rather than separate parts, the system achieves improved information accessibility while the integrated nature of the assembly helps manage manufacturing complexity through standardized production processes.
