Smart Camera-Guided Liquid Applicator

Official patent title

Smart Unit for Applying Liquid Formulations

Arabic title: وحدة ذكية لتطبيق مستحضرات سائلة

Invention

Problem

People applying therapeutic or cosmetic liquids to hard-to-see skin areas, especially the scalp, cannot easily confirm coverage or control distribution using conventional droppers or sprays.

Why it matters

Real-time visual feedback can help a user direct a liquid formulation to the intended area, check coverage, limit unnecessary consumption, and apply it independently.

Approach

A detachable smart dispensing unit places a central liquid outlet within the field of view of an angled camera. An integrated wireless connection streams the target area to a phone or tablet, and an automatic sensor starts the camera when dispensing begins.

Who may benefit

Potential beneficiaries include users of topical scalp or skin formulations, older adults and people with limited mobility, personal-care device manufacturers, topical-product companies, and smart-packaging developers.

Potential value

The design combines liquid dispensing and real-time visual guidance in one adaptable attachment, supporting more observable self-application without requiring a mirror or another person.

Background

Droppers and sprays can deliver therapeutic or cosmetic liquids, but they do not provide direct visual interaction with the application area. This is particularly limiting for areas such as the scalp or back that are difficult for the user to see, making it harder to judge coverage and distribution.

Technology overview

The unit includes a base that couples to a formulation bottle, a central dispensing opening, an angled camera arranged around the opening, wireless communication to a portable display, and an automatic activation sensor synchronized with dispensing. Dependent claims add oleophobic and glass lens protection, wide-angle imaging, lighting, blockage or lens-obstruction alerts, adjustable or interchangeable bottle couplings, an optional refillable cavity, squeeze or spring-pump delivery, an anti-drip valve, app control, and Wi-Fi or Bluetooth connectivity.

Potential applications

Camera-guided self-application of topical therapeutic liquids to the scalp and other hard-to-see skin areas.
More observable application of cosmetic liquids, serums, and scalp-care formulations.
Assistive self-care products for older adults and people with limited mobility.
Adaptable smart-dispensing attachments for bottles with different neck sizes.

Evidence-supported advantages

Streams a real-time view of the target area to a phone or tablet during dispensing.
Keeps the dispensing point within the camera's field of view to help the user observe coverage and distribution.
Automatically starts visual monitoring when dispensing activity is detected.
Supports multiple bottle-coupling and liquid-delivery configurations, including anti-drip control.

Development stage

Granted Saudi patent; prototype, testing, regulatory, and manufacturing status are not stated in the source document.

Commercial opportunity

Potential licensing and co-development partners include manufacturers of topical dermatology and scalp-care products, cosmetic applicators, assistive self-care devices, and connected packaging. Commercialization would require product engineering, usability and safety validation, regulatory assessment for intended therapeutic claims, and evaluation of cleaning, liquid compatibility, image quality, and battery performance.
