The simulated hair and nail growth are each metered, allowing the doll to be used for educational purposes to show growth of a certain length within a particular period of time. The doll head includes an internal axle, about which simulated hair fibers are wound. Selective rotation of the axle, driven by selective rotation of a knob with metered indicia, allows the apparent length of the simulated hair fibers to be adjusted in a controlled and metered fashion. The doll hand is provided with an internal sliding cartridge with simulated fingernails. Sliding of the cartridge, also in a controlled and metered fashion, allows for adjustable extension of the fingernails from fingers of the doll hand."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Doll with simulated hair and nail growth","description":"The doll with simulated hair and nail growth includes a doll head with adjustable length hair simulating hair growth, and at least one doll hand having adjustable length fingernails, simulating nail g","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10512851","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.
