Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If speedometers and cameras are installed together to detect speeding vehicles, then detection accuracy is improved, but installation and maintenance costs increase
Solution Approach 1:
The patent extracts the speed measurement function from the traditional speedometer device and implements it through image processing algorithms. The speedometer is removed from the system, and only the camera remains, while the speed analysis capability is transferred to the server that processes image data. This resolves the contradiction by eliminating the need for expensive dual-device installation while maintaining speed detection accuracy through computational methods.
Solution Approach 2:
The patent replaces the mechanical speedometer system with an optical-imaging-and-computational system. Instead of using mechanical sensors to directly measure vehicle speed, the system uses camera imaging combined with image processing algorithms to calculate speed from visual data. This substitution eliminates the need for physical speedometer hardware while achieving the same measurement objective, thereby reducing installation and maintenance costs.
2Device complexity
If only cameras are used to detect speeding vehicles, then installation and maintenance costs are reduced, but speed measurement capability is lost
Solution Approach 1:
The patent introduces an intermediary element - the server with image processing capabilities - that bridges the gap between the camera and speed measurement. The camera captures images, and the server performs computational analysis to extract speed information. This intermediary processing layer enables a camera-only system to achieve speed measurement functionality that traditionally required dedicated speedometer hardware.
Solution Approach 2:
The patent replaces the mechanical speed measurement system with an optical-computational system. The camera captures visual information, and computational algorithms process this data to determine vehicle speed. This substitution maintains speed measurement capability while eliminating the need for mechanical speedometer devices, thereby reducing installation and maintenance costs.

AI summary
Various embodiments provide an apparatus and method capable of detecting a speeding vehicle by only analyzing an image captured by a camera without the need to install and operate a speedometer. In this case, the image for detecting a speeding vehicle may be a streaming image or a CCTV image captured and transmitted by an imaging device such as a fixed CCTV camera device or a mobile CCTV camera device.
