Problem
Conventional photocuring devices using high-power UV irradiation can cause heat buildup in photocurable artificial nail gels, leading to discomfort or burning sensations in users' fingers.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-power UV irradiation is used throughout the curing process, then curing efficiency is improved, but gel temperature rises abruptly causing burning sensation in fingers
Solution Approach 1:
The patent applies preliminary action by implementing a slow-start mechanism that gradually increases UV irradiation power from a first level to a second level over a predetermined time period before reaching full power. This prevents abrupt temperature rise in the gel that causes burning sensation, while still achieving efficient curing through subsequent high-power irradiation.
Solution Approach 2:
The patent implements dynamics by making the UV irradiation power variable rather than constant. The switch control module dynamically adjusts the power level during the curing process, transitioning from low power during the slow-start period to high power for the remainder of the curing cycle, thus balancing comfort and efficiency.
2Productivity
If UV irradiation power is increased to reduce curing time, then productivity is improved, but heat generation increases causing discomfort
Solution Approach 1:
The patent applies preliminary action by implementing a slow-start mechanism that gradually increases UV irradiation power from a first level to a second level over a predetermined time period before reaching full power. This prevents abrupt temperature rise in the gel that causes burning sensation, while still achieving efficient curing through subsequent high-power irradiation.
Solution Approach 2:
The patent implements periodic action by dividing the curing process into distinct phases: a slow-start period with gradually increasing power, followed by a high-power curing phase. This periodic structure allows the gel to adapt to increasing irradiation levels, preventing excessive heat buildup while maintaining high productivity during the main curing phase.
