Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional UV lamps are used for curing UV hardening gel on nails, then the curing function is achieved, but harmful UV radiation (UVA, UVB, UVC) is emitted posing health risks
Solution Approach 1:
The patent changes the spectral parameters of the UV source by using UV LED modules that emit specific wavelengths (395nm and 365nm) instead of traditional broad-spectrum UV lamps. This parameter change allows selective emission of only the necessary curing wavelengths while eliminating harmful UVC and excessive UVB radiation, thus maintaining curing effectiveness while reducing health risks
Solution Approach 2:
The patent converts the potentially harmful broad-spectrum UV radiation into beneficial narrow-band UV LED radiation. By using UV LED modules with specific wavelength emissions, the harmful aspects of traditional UV lamps are eliminated while retaining the beneficial curing effect on the UV hardening gel
2Object-affected harmful factors
If UV LED modules are used to emit specific wavelengths for curing, then harmful radiation is minimized, but the apparatus requires precise control mechanisms
Solution Approach 1:
The patent implements automatic control where the system itself monitors and regulates the UV LED operation. The control circuit automatically detects when hands are placed in the curing chamber and activates the UV LED modules, then automatically shuts them off after a predetermined time period, eliminating the need for manual operation and reducing control complexity
Solution Approach 2:
The patent uses a control circuit that provides feedback control for the UV LED modules. The system monitors the curing process and automatically adjusts the operation timing based on the presence of hands in the chamber, creating a closed-loop control system that simplifies user interaction while maintaining precise control
3Productivity
If multiple UV LED modules are used to cover multiple fingers or toes, then curing efficiency is improved, but heat generation increases requiring dissipation mechanisms
Solution Approach 1:
The patent divides the UV lighting function into multiple separate UV LED modules instead of using a single high-power source. Each module is independently mounted on the housing and can be separately managed for heat dissipation. This segmentation allows the system to cover multiple fingers or toes simultaneously while distributing the heat generation across multiple smaller, more manageable units
Solution Approach 2:
The patent designs the housing to serve multiple functions: it provides structural support, acts as a mounting surface for UV LED modules, and functions as a heat dissipation structure. The housing material and design are selected to conduct and dissipate heat from the UV LED modules, combining structural and thermal management functions into a single component
4Reliability
If automatic control with photo interrupter and timer is implemented, then operation safety is improved, but device complexity increases
Solution Approach 1:
The patent implements automatic control where the system itself monitors and regulates the UV LED operation. The control circuit automatically detects when hands are placed in the curing chamber and activates the UV LED modules, then automatically shuts them off after a predetermined time period, eliminating the need for manual operation and reducing control complexity
