Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing materials are used in organic light emitting devices, then the device structure can be maintained, but the efficiency is insufficient and the balance between hole and electron movement is poor
Solution Approach 1:
The patent changes the chemical structure parameters of the organic material by introducing a specific hexacyclic core structure with hetero elements (Formula 1), which fundamentally alters the charge carrier transport properties. This structural parameter change enables balanced hole and electron movement while maintaining high device efficiency, resolving the contradiction between productivity and reliability.
Solution Approach 2:
The invention employs a composite molecular structure combining a hexacyclic core with hetero element derivatives and amine groups (Formula 1). This composite material design integrates multiple functional components that work synergistically to achieve both high efficiency and balanced charge carrier movement, addressing the technical contradiction effectively.
2Duration of action of stationary object
If conventional organic materials are used, then the device can operate, but the driving voltage is high and service life is limited
Solution Approach 1:
The patent modifies the molecular parameters of the organic material by incorporating the hexacyclic structure with specific hetero elements and amine groups. This parameter change optimizes the energy levels and charge transport characteristics, resulting in reduced driving voltage and extended service life simultaneously.
3Productivity
If new materials are developed to improve efficiency, then device performance can be enhanced, but the complexity of material structure increases
Solution Approach 1:
The patent segments the organic material structure into distinct functional components: a hexacyclic core structure, hetero element derivatives, and amine groups. This segmentation allows each component to perform its specific function optimally while maintaining overall structural organization, achieving high efficiency without excessive complexity.
Solution Approach 2:
The invention applies local quality by introducing specific functional groups (amine groups and hetero elements) at particular positions within the molecular structure. These localized modifications enhance charge transport properties without requiring complete restructuring of the entire material, thus improving efficiency while controlling complexity.
