Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nail varnish curing devices using ultraviolet radiation do not effectively limit exposure of uncoated body parts to UV radiation, which is harmful in high doses.
Innovation Solution
A device with a controlled layout of nine ultraviolet radiation sources and a presence sensor system that adjusts illumination zones based on hand position, ensuring only the nails are exposed to UV radiation, reducing unnecessary UV exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultraviolet radiation sources are used to cure nail varnish quickly, then the curing speed is improved, but the exposure of uncoated body parts to harmful UV radiation increases
Solution Approach 1:
The patent divides the radiation field into multiple independently controllable zones corresponding to different fingers. Each zone has its own radiation source that can be activated or deactivated separately based on the presence and position of fingers, allowing selective illumination only of coated nails while leaving uncoated areas in darkness.
Solution Approach 2:
The patent implements different illumination conditions for different spatial locations. Each finger position receives radiation only when a finger is present and properly positioned, while other positions remain unilluminated. This localizes the beneficial UV radiation effect precisely to where needed (coated nails) while avoiding harmful exposure elsewhere.
2Area of stationary object
If multiple radiation sources are used to illuminate all finger positions, then the curing coverage is improved, but the energy consumption increases
Solution Approach 1:
The patent employs dynamic control of radiation sources based on real-time detection of finger presence and position. The system activates only the radiation sources corresponding to occupied finger positions, rather than illuminating all positions simultaneously. This dynamic adaptation reduces energy consumption while maintaining complete coverage of actually used areas.
Solution Approach 2:
The patent applies radiation selectively to only those areas where fingers are present and nail varnish needs curing, rather than illuminating the entire available space. This partial action approach avoids wasting energy on empty or unnecessary areas while ensuring complete coverage of the required zones.

AI summary
The invention relates to a device for hardening nail varnish by means of ultraviolet radiation. Said device comprises: a bearing surface (26) for supporting the hands or the feet of the user; and radiation sources (38) for emitting radiation for hardening nail varnish, in the form of a light beam for illuminating the nails of the user. On the bearing surface (26), the beams define at least six illuminated portions (42) separated from each other by a non-illuminated portion, the number of illuminated portions (42) being less than nine.
