Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrodes are configured in fixed directions, then the device structure is simple, but light emission is limited to fixed directions
Solution Approach 1:
The electrode structure is divided into multiple segments (first electrode with first and second electrode surfaces, second electrode with third and fourth electrode surfaces) extending in different directions. This segmentation allows light emitting elements to be arranged in various orientations, enabling light emission in multiple directions while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The electrode configuration transitions from a single-direction linear arrangement to a multi-dimensional structure where electrodes extend in different directions (first direction and second direction). This dimensional expansion allows light emitting elements to be positioned at various angles, achieving omnidirectional light emission capability.
2Illumination intensity
If light emitting elements are aligned in fixed directions, then manufacturing is easier, but light emission coverage is limited
Solution Approach 1:
The electrode structure is designed to serve multiple functions: it provides electrical connection, defines multiple alignment directions for light emitting elements, and enables light emission in various directions. The first electrode and second electrode with their respective surfaces create a universal framework that accommodates light emitting elements oriented in different directions, achieving comprehensive light emission coverage.
Solution Approach 2:
Different regions of the electrode structure provide different alignment characteristics. The first electrode surface and second electrode surface extend in a first direction, while the third electrode surface and fourth electrode surface extend in a second direction. This local variation in electrode orientation guides light emitting elements to align in specific directions at specific locations, achieving diverse light emission patterns.
3Adaptability or versatility
If electrodes extend in multiple directions, then light emission in various directions is achieved, but electrode structure becomes more complex
Solution Approach 1:
The electrode structure employs asymmetric configuration where the first electrode and second electrode have different surface orientations. The first electrode surface and second electrode surface extend in a first direction, while the third electrode surface and fourth electrode surface extend in a second direction. This asymmetric design enables diverse light emission directions while maintaining structural clarity through defined geometric relationships.
