Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OLED technology is used to achieve high luminous efficiency and flexibility, then the screen can ensure certain flexibility and adaptability, but the service life and resistance to environmental factors need to be improved
Solution Approach 1:
The device is segmented into distinct functional layers including a base substrate, conductive coil layer, light-emitting layer, and packaging structure. This segmentation allows each layer to be optimized independently for its specific function while maintaining overall flexibility and reliability.
Solution Approach 2:
The patent employs composite material structures including the packaging structure with multiple protective layers, the conductive coil integrated with electrodes, and the light-emitting layer with specific organic materials. These composite structures enhance both flexibility and environmental resistance simultaneously.
2Use of energy by moving object
If a conductive coil structure is used for electromagnetic induction power transmission, then energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The conductive coil is merged with the first and second electrodes into a single integrated structure. This combining reduces the number of separate components and simplifies the overall device architecture while maintaining the electromagnetic induction power transmission function for energy efficiency.
Solution Approach 2:
The conductive coil structure serves multiple functions: it acts as both the power transmission element through electromagnetic induction and as part of the electrode structure for light emission. This multi-functionality reduces the need for separate dedicated components, thereby reducing complexity.
3Duration of action of stationary object
If multiple protective layers and packaging structures are added to prevent environmental damage, then service life is extended, but the device complexity increases
Solution Approach 1:
The packaging structure with multiple protective layers is designed and integrated in advance during the manufacturing process. This preliminary protection prevents environmental damage before it can affect the light-emitting components, extending service life without requiring complex post-manufacturing assembly or maintenance.
Solution Approach 2:
The packaging structure uses composite material layers including inorganic and organic protective layers. These composite materials provide enhanced environmental resistance through the synergistic properties of different materials, extending service life while maintaining a relatively simple overall structure.
4Illumination intensity
If a magnetic conductive sheet is added to enhance luminous brightness, then light emission performance is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The magnetic conductive sheet modifies the magnetic field parameters in the light-emitting region, enhancing the luminous brightness through changes in electromagnetic field distribution. This parameter change approach allows for performance improvement without fundamentally altering the basic device structure or manufacturing process.
Solution Approach 2:
The magnetic conductive sheet is positioned specifically in the light-emitting region where it is needed to enhance brightness. This localized application of the magnetic sheet avoids adding complexity to the entire device structure and simplifies manufacturing by focusing the enhancement function to a specific area.
