Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of image capture unit positions is used, then the device complexity is reduced, but the measurement precision deteriorates due to inaccurate positioning
Solution Approach 1:
The system performs self-positioning and self-focusing through automated control. The control unit automatically adjusts the positions of multiple image capture units and their focusing based on product information, eliminating the need for manual intervention and ensuring consistent positioning accuracy.
Solution Approach 2:
Manual mechanical adjustment is replaced by an automated control system that uses electronic signals to position and focus image capture units. The control unit receives product information and automatically calculates and executes the positioning and focusing requirements, substituting human operation with automated control.
2Measurement precision
If a single image capture unit is used, then the device complexity is reduced, but the measurement precision deteriorates due to limited digital information
Solution Approach 1:
The inspection task is divided into multiple segments by using several image capture units positioned at different locations and angles. Each unit captures images of different portions or aspects of the product, and the control unit integrates this segmented information to achieve comprehensive and accurate inspection.
Solution Approach 2:
The system transitions from a single-point inspection to multi-dimensional inspection by positioning image capture units at different spatial locations and angles around the product. This spatial distribution enables capture of comprehensive product information from multiple perspectives simultaneously.
3Reliability
If manual positioning is used, then the ease of operation is improved, but the reliability deteriorates due to erroneous results
Solution Approach 1:
The control unit receives feedback information about the product (such as size and outline data) and automatically adjusts the positioning and focusing of image capture units accordingly. This closed-loop control ensures that the system adapts to different products while maintaining reliable inspection results without requiring manual intervention.
Solution Approach 2:
The system automatically changes operational parameters (position coordinates, focusing distance, capture timing) based on product characteristics. The control unit calculates appropriate parameters for each inspection scenario and executes them, ensuring reliable results while eliminating manual parameter adjustment.
4Adaptability or versatility
If fixed position image capture units are used, then the device complexity is reduced, but the adaptability deteriorates due to scene restrictions
Solution Approach 1:
The system transitions from fixed static positioning to dynamic adjustable positioning. Image capture units can be automatically repositioned and refocused based on different inspection requirements and product characteristics, enabling the system to adapt to various inspection scenarios while maintaining manageable complexity through automated control.
Solution Approach 2:
The inspection system is designed with multi-functionality to handle diverse product types and inspection requirements. By incorporating multiple adjustable image capture units controlled by a central unit that receives product information, the system can adapt to different products, sizes, and inspection needs, achieving universal applicability.
