Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods (visual inspection, floating in liquid) are used to detect defects in golf balls, then defect detection accuracy is improved, but detection time increases making it unsuitable for production processes
Solution Approach 1:
The patent replaces mechanical/physical inspection methods (visual inspection, floating in liquid) with an electromagnetic field-based detection system. The system uses electromagnetic signals to excite the golf ball and analyzes the reflected signals to detect internal defects such as eccentric cores and imbalanced internal media, enabling rapid automated inspection suitable for production processes while maintaining high detection accuracy
Solution Approach 2:
The patent changes the detection parameter from physical/visual properties to electromagnetic properties. By measuring the reflection characteristics of electromagnetic signals at different frequencies, the system can identify internal defects without requiring time-consuming physical inspection methods, thus reducing detection time while maintaining precision
2Productivity
If electromagnetic signals are used to detect golf ball symmetry and internal uniformity, then detection speed is improved, but device complexity increases
Solution Approach 1:
The electromagnetic detection system is designed to perform multiple detection functions using a single apparatus. It can detect various types of defects including eccentric cores, imbalanced internal media, and outer shell damages by analyzing electromagnetic signal reflections at different frequencies, eliminating the need for multiple separate inspection devices and reducing overall system complexity
Solution Approach 2:
The patent uses electromagnetic signals as an intermediary to indirectly detect internal defects. Instead of directly observing or physically interacting with the golf ball's internal structure, the system sends electromagnetic signals through the ball and analyzes the reflected signals, which carry information about internal symmetry and uniformity, enabling fast detection without complex direct measurement devices
