Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual deburring is used to facet workpiece edges, then personnel effort is reduced, but the resulting facets are inhomogeneous and require high skill levels
Solution Approach 1:
The patent replaces manual mechanical deburring with an automated system combining optical measurement and computer-controlled movement. A camera captures workpiece edge positions, a computer calculates facet toolpaths, and a motor-driven tool executes the faceting, eliminating manual operation while ensuring homogeneous facets through precise automated control.
2Manufacturing precision
If CNC-controlled beveling is used to achieve homogeneous facets, then manufacturing precision is improved, but programming effort and device complexity increase
Solution Approach 1:
The system performs self-measurement and self-programming. The camera automatically measures the workpiece edge geometry, and the computer automatically generates the facet toolpath based on the measured positions, eliminating the need for external programming effort while maintaining homogeneous facet quality through precise automated control.
3Device complexity
If manual deburring is used for small batch production, then device complexity is reduced, but productivity and coating quality deteriorate
Solution Approach 1:
The patent creates a universal system that combines a simple workpiece holder, camera, computer, and motor-driven tool into a multi-functional automated faceting device. This single system handles measurement, programming, and execution, providing high productivity for small batches without requiring complex dedicated CNC machinery.
4Reliability
If manual deburring is used to prevent coating flaking, then coating quality is improved, but personnel effort and time consumption increase
Solution Approach 1:
The patent replaces time-consuming manual deburring with automated optical measurement and computer-controlled faceting. The camera quickly captures edge positions, the computer rapidly calculates toolpaths, and the motor-driven tool efficiently executes faceting, ensuring reliable coating quality without significant time consumption.
