Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional automatic spraying system with fixed spraying manner is used, then the spraying process is automated and efficient, but it cannot accommodate different contours and sizes of various shoe soles, resulting in non-uniform adhesive application
Solution Approach 1:
The spraying system transitions from a fixed, static spraying manner to a dynamic, adaptive spraying process. The system captures 3D images of different shoe soles, processes the contour data, and automatically adjusts spraying parameters (such as spraying points, spray width, and adhesive amount) based on the specific geometry of each sole, enabling the automated system to adapt to varying contours and sizes
Solution Approach 2:
The system changes multiple spraying parameters dynamically based on the 3D contour data of each shoe sole. This includes adjusting the number and position of spraying points, modifying spray width, and controlling adhesive application amount according to the specific geometric parameters of each sole, thereby achieving uniform adhesive coverage across different sole designs
2Adaptability or versatility
If manual adhesive application is used, then the process can be adjusted to fit different shoe soles, but it results in non-uniform adhesive application and is inefficient
Solution Approach 1:
The system replaces manual mechanical adhesive application with an automated spraying system guided by 3D image processing. The computing device processes the 3D contour data and generates precise spraying instructions, which control the spray tool to deposit adhesive uniformly across the sole surface, eliminating the non-uniformity inherent in manual application while maintaining adaptability through digital parameter adjustment
3Ease of operation
If a fixed spraying manner is used for all shoe soles, then the spraying system is simple to operate, but it cannot provide precise adhesive application for soles with varying contours and sizes
Solution Approach 1:
The spraying system performs self-adjustment by automatically capturing 3D images of each shoe sole, processing the contour data through the computing device, and generating optimized spraying parameters without requiring manual intervention or reconfiguration. The system serves itself by adapting to different sole geometries through automated image processing and parameter calculation, maintaining ease of operation while achieving precise adhesive application
