Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle monitoring systems are cumbersome and slow, making it difficult to efficiently track and identify vehicles, especially cars, buses, and yachts, and prevent the use of fake or stolen license plates.
Innovation Solution
A monitoring system utilizing optical reading devices to detect machine-readable codes, such as barcodes and QR codes, on vehicle license plates, which can be read electronically by standard or long-range scanners, allowing for quick and efficient identification of vehicles without disrupting traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing surveillance systems are used to monitor vehicles, then vehicle tracking is achieved, but the system becomes cumbersome and slow
Solution Approach 1:
The patent replaces complex mechanical surveillance systems with optical reading devices that use light to detect machine-readable codes on license plates. This substitution of optical detection for mechanical surveillance achieves rapid vehicle identification without the complexity and slowness of traditional systems
Solution Approach 2:
The patent uses machine-readable codes (barcodes, QR codes, data matrix codes) as optical copies of vehicle identification information. These codes are affixed to license plates and can be rapidly read by optical scanners, enabling fast vehicle tracking without physical inspection or complex mechanical systems
2Measurement precision
If vehicle monitoring requires stopping vehicles for inspection, then accurate identification is achieved, but traffic flow is disrupted
Solution Approach 1:
The patent enables continuous vehicle monitoring by reading machine-readable codes on moving vehicles without requiring them to stop. The optical reading devices can scan codes on license plates while vehicles are in motion, maintaining both identification accuracy and traffic flow continuity
Solution Approach 2:
The machine-readable code on the license plate serves as an intermediary that carries vehicle identification information in a format that can be rapidly read by optical scanners. This intermediary enables accurate identification without physical inspection or vehicle stoppage
3Ease of manufacture
If single machine-readable code is used on license plates, then simplicity is maintained, but counterfeiting becomes easier
Solution Approach 1:
The patent divides the identification system into multiple independent machine-readable codes on each license plate. These multiple codes provide redundant verification and make counterfeiting more difficult, as all codes must be replicated accurately. The segmentation of identification elements enhances reliability while maintaining manufacturing simplicity
Solution Approach 2:
The patent uses different types of machine-readable codes (barcode, QR code, data matrix code) with different optical and structural parameters on the same license plate. This variety in code parameters makes counterfeiting more difficult while the codes remain manufacturable using standard printing or application techniques
