Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If large LED surfaces are used to illuminate objects, then realistic illumination is achieved, but the system becomes very cost-intensive and difficult to adapt
Solution Approach 1:
The large LED surface is segmented into multiple individual LED elements that can be independently controlled. This allows the system to adapt to different lighting situations by selectively activating specific segments while maintaining realistic illumination through controlled intensity and color distribution across the segments.
Solution Approach 2:
The LED elements are equipped with individual control channels that enable dynamic adjustment of intensity and color temperature. This dynamic control allows the system to adapt to various lighting situations (daylight, incandescent, fluorescent, etc.) while maintaining realistic illumination effects.
2Illumination intensity
If large LED surfaces are used to illuminate objects, then realistic illumination is achieved, but the system becomes very cost-intensive
Solution Approach 1:
The illumination system is divided into multiple independent LED elements that can be manufactured and assembled separately. This segmentation reduces overall system cost by allowing modular construction and enabling the use of standard, readily available LED components rather than requiring a single large custom LED surface.
Solution Approach 2:
The system uses individual LED elements that are relatively inexpensive and can be replaced individually if needed. This approach reduces the overall cost-intensiveness compared to a single large LED surface, as cheaper components are used and only the specific element that fails needs replacement rather than the entire system.
3Adaptability or versatility
If individual LED elements are controlled individually, then light with different intensities and colours can be mixed, but the device complexity increases
Solution Approach 1:
The control unit is designed with universal functionality to handle multiple LED elements through a standardized control interface. Each LED element receives control signals for intensity and color temperature through common control channels, allowing the control unit to manage diverse lighting requirements without requiring separate complex control circuits for each element.
Solution Approach 2:
The control unit manages individual LED elements by adjusting key parameters (intensity and color temperature) through standardized control signals. This parameter-based control approach simplifies the device complexity by focusing control efforts on the most important lighting characteristics rather than requiring separate control mechanisms for each individual LED property.
