The vending method comprises: collecting the weight of products on a shelf before and after vending (S1); calculating the difference of the change between the weight of the products on the shelf before vending and the weight of the products on the shelf after vending (S2); and if the difference of the change is less than a first weight change threshold, issuing an alarm prompt (S3), wherein the first weight change threshold is less than or equal to zero. Using the present invention may promptly determine the misplacement and replacement of the products without relying on an RFID tag."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vending machine and vending method and vending system therefor","description":"A vending machine (100) and a vending method and vending system (1000) therefor, the vending machine (100) comprising a machine body (10), a door body (20), and at least one layer of shelves (30) and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11501594","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
