Beauty Tool Viewfinder Positioning for Precise Skin Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held devices for applying facial skin treatments and cosmetics are difficult to position precisely on specific areas due to obstruction by the device itself during application, especially for spray actives.
Innovation Solution
Incorporation of an optical system with a camera and viewfinder in the dispenser device to enable precise targeting of the dispensing nozzle, combined with sensors and motors for automated control and adjustment, allowing for accurate application on desired skin conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held dispenser device is used for applying facial skin treatments, then portability and ease of use are improved, but positioning precision on specific skin areas deteriorates due to device obstruction
Solution Approach 1:
The patent uses a camera to capture an image of the skin area and displays it on a viewfinder, creating a visual copy of the target area. This allows the user to see the dispensing zone without needing to directly view it, eliminating the obstruction problem while maintaining positioning precision. The camera system provides a replicated visual representation that guides the application process.
Solution Approach 2:
The viewfinder acts as an intermediary between the user and the skin area. Instead of directly viewing the skin surface, the user views the camera-captured image on the viewfinder. This intermediary system allows precise positioning without the device blocking the view of the target area.
2Ease of operation
If the device structure is simplified for ease of use, then ease of operation is improved, but positioning precision and control deteriorate
Solution Approach 1:
The camera and viewfinder system provides real-time visual feedback to the user about the dispensing zone. The user can see the captured image on the viewfinder and adjust the device positioning accordingly, creating a feedback loop that enables precise control without requiring complex mechanical structures. The visual feedback system allows intuitive adjustment for accurate positioning.

Data Source
AI summary
A hand-held dispenser device includes a dispensing nozzle, wherein the dispensing nozzle is configured to point toward a dispensing direction, a camera configured to receive an image of a dispensing zone that the dispensing nozzle points toward, and a viewfinder that displays the image of the dispensing zone that the dispensing nozzle points toward. The camera and viewfinder enable the user to precisely point the device to treat a desired area.
