State-of-the-art cosmetic defect detection with AI is a key enabler for making profitable business in the refurbishment of smartphones. It is accurate, relentless, and objective and it beats humans in repeatability.
Your whole business case, pricing, consumer trust, everything is based on your capability to reliably analyze and classify the defects on the device.
How is your process today?
Humans are flexible and great learners. This is helpful in a business where you need to understand how visual problems might look on different types of surfaces. Grading the phones to different categories is based on experience, which can be trained. But even after a long experience, it is still very likely that grading errors happen. There are various reasons, like inattention, tiredness, or distraction. Another major issue is the constant change of personnel, which brings a variety into the grading process that should exist. This makes the work boring and highly error-prone.
How machine vision enhanced with AI can help
Machine vision can help to overcome human error in the visual inspection of smartphones by providing consistent and reliable inspection results. Unlike humans, machine vision systems can perform inspections at a high speed and with great accuracy, reducing the likelihood of human error.
Human inspectors may overlook or miss certain defects, particularly if they are not trained properly or are fatigued. Machine vision, on the other hand, can detect and analyze every aspect of the smartphone, ensuring that all defects are identified and addressed. By using AI to detect and identify defects, refurbishers can ensure that every smartphone is thoroughly inspected and meets specific quality standards, resulting in higher customer satisfaction and repeat business.
In addition, machine vision can be programmed to perform specific tests and measurements consistently, ensuring that the inspection process is objective and consistent. This can be particularly useful in identifying defects that may be difficult for human inspectors to see, such as hairline cracks or minute scratches.
Furthermore, machine vision can work 24/7 without needing breaks, allowing for increased productivity and efficiency. By automating the inspection process, manufacturers can significantly reduce the time and resources required for visual inspection.
One important gain is the data. Once you start using machine vision-based systems, you can start using data to improve your business case.
One example from real life: An end-customer tries to cheat the system by reporting that a phone he bought was graded as A, even though the actual grade was only C. He then tries to get his money back or to get a new phone from the seller. With a machine, that did the testing the seller could simply check the original grading and see that it is only a C. A customer that tries to cheat could easily be caught.
Most importantly the data will help you in the long run of your business. You can start to see if there are any anomalies in your process or how your suppliers for the phones differ from each other or performance over time.
