Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional light curing devices use a single fixed wavelength light source, then the device structure is simple, but it cannot accommodate different types of gel nail polish or varying thicknesses requiring different wavelengths
Solution Approach 1:
The light source is divided into multiple independent light-emitting elements, each emitting at a different wavelength. This segmentation allows the device to provide multiple wavelengths while maintaining a relatively simple overall structure, as each element can be independently controlled through software or simple circuitry rather than requiring complex mechanical switching mechanisms.
Solution Approach 2:
The lighting module is designed to perform multiple functions by incorporating light-emitting elements that can emit different wavelengths. This multi-functional design allows a single device to handle various types of gel nail polish and thicknesses, eliminating the need for multiple specialized devices and thereby managing complexity through consolidation rather than proliferation of separate components.
2Loss of information
If conventional light curing devices lack operational indicators, then the device structure is simpler, but users cannot determine the curing duration or device activation state
Solution Approach 1:
The indicator module uses color-changing LEDs to convey different operational states (such as standby, curing in progress, completion). This approach provides rich information communication using simple visual elements that add minimal structural complexity. The color changes serve as intuitive feedback without requiring complex display mechanisms or multiple separate indicator components.
3Duration of action of moving object
If light curing devices provide fixed duration curing, then the control system is simpler, but it cannot accommodate different curing time requirements for various polish types and thicknesses
Solution Approach 1:
The control system is designed to be dynamic, allowing users to adjust curing duration based on specific needs such as polish type and thickness. This dynamic control capability is implemented through programmable timers and microcontroller-based logic that can store and recall multiple preset time values, providing flexibility without requiring complex mechanical adjustment mechanisms or multiple fixed-duration circuits.
