Alternating UV Modules for Hand-Curing Nail Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manicure curing devices emit excessive ultraviolet radiation, causing discomfort and increasing the risk of skin damage and skin cancer, particularly affecting the back of the hand.
Innovation Solution
A manicure curing device with a housing containing a first and second light-emitting module, where the first control part controls the first light-emitting module to emit light and the second light-emitting module not to emit light, and the second control part controls the second light-emitting module to emit light and the first light-emitting module not to emit light, thereby reducing illumination on the back of the hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the manicure curing device emits ultraviolet light continuously, then the curing effect is improved, but the skin damage risk increases
Solution Approach 1:
The patent divides the internal cavity into multiple zones with separate light-emitting modules positioned at different locations. The cavity is segmented into front, rear, left, and right areas, each equipped with independent UV light sources that can be controlled separately. This segmentation allows selective illumination of different hand regions, reducing unnecessary UV exposure to areas like the back of the hand while maintaining effective curing where needed.
Solution Approach 2:
The patent implements dynamic control of light-emitting modules based on real-time detection of hand position and finger insertion status. The control system adjusts which modules are active according to the actual curing needs, transitioning between different lighting patterns. This dynamic adjustment ensures UV light is emitted only where and when required, minimizing overall exposure and skin damage risk while preserving curing effectiveness.
2Reliability
If multiple light-emitting modules are used to improve curing coverage, then the curing effectiveness is improved, but the ultraviolet irradiation on the back of the hand increases
Solution Approach 1:
The patent assigns different functional roles to light-emitting modules based on their positions within the internal cavity. Front modules are optimized for illuminating inserted fingers, rear modules for specific angle illumination, and side modules for lateral coverage. Each module's emission is locally optimized for its specific region, ensuring effective curing coverage while preventing excessive UV exposure to areas like the back of the hand that should remain protected.
Solution Approach 2:
The patent incorporates detection modules that provide real-time feedback on hand position, finger insertion depth, and which fingers are being cured. The control system uses this feedback information to dynamically adjust the emission state of each light-emitting module. When the back of the hand is detected or when certain fingers are not being cured, the corresponding modules are deactivated, preventing unnecessary UV irradiation while maintaining effective curing where needed.
