Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skincare applicators lack precision in liquid delivery, are prone to leakage, have ergonomic issues, and often require separate devices for phototherapy, leading to inefficient and inconvenient skincare treatments.
Innovation Solution
An applicator head with a rotatable liquid supply channel, an elongated ergonomic roller, and integrated phototherapy functionality, featuring a leak-resistant design and modular components for controlled liquid dispensing and simultaneous skincare treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional applicators are used for liquid application, then direct application is simple, but precision in controlling liquid amount is poor and leakage occurs
Solution Approach 1:
The liquid supply channel is designed to be rotatable relative to the base, allowing dynamic alignment to control liquid flow. When aligned, liquid flows to the roller; when misaligned, flow is blocked. This dynamic mechanism enables precise control and prevents leakage during storage or transport.
Solution Approach 2:
The rotatable liquid supply channel acts as an intermediary control element between the liquid container and the applicator roller. It mediates liquid flow by selectively aligning or misaligning with the connecting hole, providing precise control without direct manual intervention.
2Productivity
If conventional rollers are used, then application is simple, but ergonomic design is limited and application efficiency is reduced
Solution Approach 1:
The roller is designed with a curved surface that conforms to skin contours, improving both ergonomic comfort and application efficiency. The elongated curved shape allows better contact with the skin surface area, enhancing product distribution while maintaining user comfort during prolonged use.
Solution Approach 2:
The roller is extended in length along the main body, transitioning from a conventional small diameter to an elongated form. This dimensional change increases the contact area with the skin, improving application efficiency and allowing coverage of larger skin surfaces in fewer strokes.
3Adaptability or versatility
If phototherapy functionality is integrated, then skincare treatment is enhanced, but device complexity and portability are compromised
Solution Approach 1:
The phototherapy lamp is integrated into the applicator head, merging liquid application and light therapy functions into a single device. The lamp is positioned within the head structure, allowing simultaneous or sequential use of both functions without requiring separate devices, thereby enhancing versatility while maintaining compactness.
Solution Approach 2:
The applicator device is designed to perform multiple functions: liquid application via the roller and phototherapy via the integrated lamp. This multi-functional design allows a single device to replace multiple separate tools, improving adaptability for different skincare needs while avoiding the complexity of managing multiple devices.

AI summary
The present invention relates to an applicator head for applying liquid from a liquid supply container to a user's skin. The applicator head includes a cover, a base, a main body, and a roller. The base has a connecting sleeve with a connecting hole for communication with the container. The main body is rotatably connected to the base and defines a liquid supply channel extending to a mounting groove. A liquid supply tube delivers liquid to the groove, where the roller is rotatably mounted to apply the liquid. Rotation of the main body relative to the base alternately establishes or blocks fluid communication, thereby preventing leakage when not in use. A sealing gasket and stepped retention surfaces provide reliable sealing and secure assembly. The main body further integrates a circuit board, power supply, and phototherapy lamp with light-emitting elements, enabling combined liquid application and light therapy treatment.
