Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time image detection and automatic adjustment system is added, then soldering quality and process consistency are improved, but device complexity increases
Solution Approach 1:
The system uses image sensors to detect solder wave properties in real-time and feeds this information back to the controller, which automatically adjusts nozzle position or solder flow rate to maintain optimal soldering conditions, thereby improving consistency without requiring manual intervention
Solution Approach 2:
The patent replaces manual visual inspection and manual adjustment of solder wave parameters with an automated optical detection and control system, substituting human operators with image sensors and controllers to reduce variability and improve precision
2Measurement precision
If multiple image sensors are used for comprehensive detection, then measurement accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The detection system is divided into multiple image sensors, each responsible for detecting specific parameters of the solder wave (such as height, width, shape), allowing comprehensive measurement while maintaining modularity and manageable complexity
Solution Approach 2:
The image sensors serve multiple functions: detecting solder wave properties, monitoring nozzle condition, and providing data for process control, thereby maximizing the utility of each sensor and reducing the need for additional specialized devices
