Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional X-ray scanning methods are used for golf ball concentricity verification, then the inspection process can be performed, but the measurement precision is insufficient leading to quality control inconsistencies
Solution Approach 1:
The patent replaces traditional mechanical measurement systems with an optical imaging system. Specifically, it uses a charge-coupled device (CCD) camera to capture images of the golf ball layers, and applies image processing algorithms to determine concentricity. This substitution of mechanical methods with optical and computational methods enables higher measurement precision and more consistent quality control, directly resolving the technical contradiction between measurement precision and reliability.
2Measurement precision
If edge detection algorithms are applied to determine layer dimensions from images, then measurement precision improves, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent introduces image processing software algorithms as an intermediary between the CCD camera and the measurement results. These algorithms automatically detect edges, calculate dimensions, and determine concentricity without requiring complex hardware modifications. This intermediary computational layer enables high measurement precision while keeping the physical device relatively simple, resolving the contradiction between measurement precision and device complexity.
