A good product refers to a product that can be used stably by users. The following is an explanation of a good product:
1, there must be a reason for the failure of a good product, and the potential failure causes further increase, and the failure occurs only when the function is blocked. Therefore, it can be considered that products with normal characteristics also have potential failure causes.
2. Good products expand the definition of the above-mentioned fault analysis. The so-called fault analysis is to investigate the cause of the fault and take corrective measures against the cause of the fault. The analysis object is not limited to faulty products, but also includes good products with good characteristics.
3. Generally speaking, fault analysis is considered as fault product analysis. Here, it is boldly put forward that the products with normal characteristics are the analysis objects, which is likely to be of great significance to evaluate the existence of potential failure causes or manufacturing conditions. Therefore, the concept of good product analysis is put forward.
4. Both the initial failure and accidental failure of good products occur in manufacturing engineering, which is the result of the designer's accidental infiltration of the failure reasons.
