Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full-power UV light is used during the entire curing process, then curing efficiency is improved, but heat generation increases causing burning sensation
Solution Approach 1:
The patent applies periodic action by implementing a slow-start mode where UV LEDs operate at reduced power levels initially, then gradually transition to full power. This periodic variation in power output prevents excessive heat buildup while ensuring complete curing, resolving the contradiction between curing efficiency and heat generation.
Solution Approach 2:
The patent implements dynamics by making the UV LED power output adjustable and time-dependent. The control module dynamically changes the power level from a first power level (reduced) to a second power level (full), allowing the system to adapt its output to minimize heat while maintaining curing effectiveness.
2Object-affected harmful factors
If UV LED power is reduced to minimize heat, then comfort is improved, but curing efficiency decreases
Solution Approach 1:
The patent applies preliminary action by first applying reduced-power UV light to initiate the curing process and warm up the gel, then transitioning to full power to complete the curing. This preliminary low-power phase prevents excessive heat buildup while still starting the curing process, and the subsequent full-power phase ensures complete curing efficiency.
Solution Approach 2:
The control module dynamically adjusts the UV LED power level based on the curing process stage, transitioning from a first power level to a second power level. This dynamic adjustment ensures optimal balance between comfort (reduced heat) and curing efficiency (sufficient UV exposure).
