Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single photographing component is used for all detected members, then device complexity is reduced, but adaptability to different shapes deteriorates
Solution Approach 1:
The patent implements a multi-functional detection system where multiple photographing components (first photographing component for rectangular cuboid posts, second photographing component for cylindrical posts) are integrated into a single detection device. Each component is specialized for specific post shapes, allowing the system to handle diverse battery post geometries effectively without requiring separate detection devices for each shape type.
Solution Approach 2:
The detection system is segmented into specialized sub-systems: a first photographing component dedicated to rectangular cuboid shaped posts and a second photographing component dedicated to cylindrical posts. This segmentation allows each component to be optimized for its specific shape type, improving imaging quality and detection accuracy while maintaining overall system manageability through modular architecture.
2Measurement precision
If multiple dedicated photographing components are used for different shapes, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional detection system where multiple photographing components (first photographing component for rectangular cuboid posts, second photographing component for cylindrical posts) are integrated into a single detection device. Each component is specialized for specific post shapes, allowing the system to handle diverse battery post geometries effectively without requiring separate detection devices for each shape type.
Solution Approach 2:
The patent combines multiple specialized photographing components into a single integrated detection device with a unified control system. The first photographing component and second photographing component share common mounting structures, control circuits, and processing systems, which reduces overall system complexity compared to having completely separate detection devices while maintaining high detection accuracy for different post shapes.
3Ease of manufacture
If a single photographing component is used, then manufacturing cost is reduced, but retooling time increases
Solution Approach 1:
The detection device incorporates dynamic switching capability between different photographing components based on the detected post shape. The system can dynamically select and activate the appropriate photographing component (first for rectangular, second for cylindrical) during production, eliminating the need for manual retooling when switching between different battery post types and maintaining continuous production flow.
Solution Approach 2:
The system performs preliminary identification of post shape and pre-activates the appropriate photographing component before the actual detection process begins. This preliminary action ensures that the correct component is ready and configured, eliminating retooling delays and enabling seamless transition between different post geometries during production.
4Adaptability or versatility
If dedicated photographing components are allocated for each shape, then adaptability is improved, but device complexity increases
Solution Approach 1:
The detection system incorporates feedback mechanisms that automatically identify the post shape and select the appropriate photographing component. The control system receives information about the detected member shape and provides feedback to activate the corresponding component, eliminating the need for manual configuration and reducing system complexity despite having multiple specialized components available.
