Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is used to monitor parking spaces, then the device can capture visual information, but the camera quality deteriorates in weak ambient light resulting in inaccurate determination of parking space state
Solution Approach 1:
An ultrasonic probe is introduced as an intermediary detection device that operates independently of ambient light conditions. The probe emits ultrasonic waves to detect occupancy status, providing accurate measurement precision regardless of illumination intensity, thus resolving the contradiction between measurement accuracy and lighting conditions.
2Reliability
If a surveillance device is installed in a parking lot, then monitoring capability is provided, but the device becomes vulnerable to vandalism
Solution Approach 1:
The patent replaces the traditional exposed camera mechanism with an integrated ultrasonic detection system. The ultrasonic probe operates within the housing without requiring exposed optical components, eliminating the mechanical vulnerability to vandalism while maintaining monitoring capability through acoustic wave detection.
3Adaptability or versatility
If a fixed camera angle is used, then the device structure is simple, but the monitoring coverage is limited and angle adjustment is inconvenient
Solution Approach 1:
The mounting housing is designed with rotational capability around a central axis, transforming the fixed camera angle into a dynamic, adjustable configuration. This allows the camera to rotate and monitor different directions while maintaining a relatively simple integrated mounting structure, resolving the contradiction between adaptability and structural complexity.

AI summary
A device for processing images is provided. The device comprises a support bar (1), a mounting housing (2) mounted with a camera lens (4), and a connector (3) configured to connect the support bar (1) to the mounting housing (2). The mounting housing (2) is integrally rotatable with the connector (3) with respect to the support bar (1). The mounting housing (2) may further be mounted with an ultrasonic probe (6) and a lightening device (5). The ultrasonic probe (6) is configured to monitor a predefined change, such as a change in an occupation state of a parking space, and the camera lens (4) and the lightening device (5) are controlled at least by the monitored change. When the ultrasonic probe (6) monitors that a car is leaving or entering a parking space, the camera lens (4) and the lightening device (5) may be switched on.
