Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a three-dimensional emission surface is implemented to create a unique visual signature, then aesthetic character is improved, but device complexity increases
Solution Approach 1:
The lighting device is divided into multiple independent light-emitting modules, each with its own support structure. This segmentation allows complex three-dimensional emission surfaces to be constructed from simpler modular components, reducing overall device complexity while maintaining aesthetic character.
Solution Approach 2:
The support structure serves multiple functions: it provides mechanical support for the organic light-emitting diode, positions the emission surface in three-dimensional space, and enables various emission geometries. This multi-functionality reduces the need for separate components, thereby reducing device complexity.
2Adaptability or versatility
If multiple functions are integrated into the lighting device, then versatility is improved, but device complexity increases
Solution Approach 1:
The lighting device integrates multiple functions including illumination, direction indication, and aesthetic signaling within a single modular structure. The organic light-emitting diode and support structure are designed to accommodate various operational modes, providing versatility without requiring separate dedicated components for each function.
Solution Approach 2:
The device incorporates controllable light emission patterns including sequential activation of modules for scrolling direction indicators. This dynamic control capability allows a single device structure to perform multiple functions by varying the activation sequence and intensity of individual modules.
3Manufacturing precision
If a flexible organic light-emitting diode is mounted on a three-dimensional surface without play, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The flexible organic light-emitting diode is divided into multiple modular segments that can be independently mounted on the three-dimensional support surface. This segmentation simplifies the mounting process by allowing each module to be positioned and secured separately, improving precision while maintaining ease of manufacture.
Solution Approach 2:
The use of flexible organic light-emitting diodes with thin-film construction allows these components to conform to three-dimensional support surfaces. The flexibility of these thin-film structures enables them to adapt to complex geometries without requiring precise pre-forming, thereby improving mounting precision while simplifying manufacturing.
