Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If targets wear identification systems like light-emitting diodes or chips, then target identification capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent extracts the identification function from the target object and relocates it to the monitoring device itself. By equipping the device with multiple cameras (visible, infrared, thermal) that can independently detect and identify targets, the system eliminates the need for targets to wear identification devices. The identification capability is built into the monitoring system through multi-spectral image processing and pattern recognition algorithms.
Solution Approach 2:
The monitoring device integrates multiple camera types (visible, infrared, thermal) into a single universal system that can perform both detection and identification functions simultaneously. This multi-functional approach allows the device to operate in various lighting conditions and identify targets without requiring separate identification equipment on each target.
2Reliability
If multiple types of cameras are integrated on a common support, then target detection capability in various conditions is improved, but device structure complexity increases
Solution Approach 1:
The patent merges multiple camera types (visible, infrared, thermal) onto a single common support structure with a unified housing. This consolidation allows the system to capture data across different spectral ranges simultaneously, ensuring reliable target detection whether in bright light, darkness, or challenging illumination conditions, while maintaining a compact integrated design.
3Ease of operation
If cameras are mounted on a portable common support, then ease of installation and maintenance is improved, but structural stability may be compromised
Solution Approach 1:
The common support structure incorporates adjustable and removable mounting features that allow the device to be easily installed and maintained while maintaining structural stability during operation. The portable design includes standardized mounting interfaces and secure fastening mechanisms that ensure stability when deployed, while facilitating easy repositioning and maintenance access.
