Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If borate complexes with Mg or Ba are used in organic electronic devices, then device performance is achieved, but lifetime and driving voltage characteristics are insufficient
Solution Approach 1:
The patent changes the metal parameter from Mg or Ba to Ca or Sr in the borate complex structure. This parameter change results in improved thermal stability and electronic properties, leading to enhanced device lifetime and driving voltage characteristics while maintaining good electron transport performance
Solution Approach 2:
The patent creates composite borate complexes combining specific metals (Ca or Sr) with heterocyclic ligand structures. This composite approach allows optimization of both thermal properties and electronic structure, resolving the contradiction between device lifetime and driving voltage efficiency
2Adaptability or versatility
If borate complexes are used in organic electronic devices, then electron transport function is achieved, but selection of applicable matrix materials is limited
Solution Approach 1:
The patent modifies the metal center parameter in the borate complex from traditional options to Ca or Sr, which exhibits superior thermal stability. This parameter change enables the complex to be compatible with a broader range of matrix materials while maintaining reliable thermal properties
Solution Approach 2:
The Ca and Sr borate complexes developed in the patent possess universal applicability across different matrix materials. The heterocyclic ligand structure combined with Ca or Sr metal centers creates a versatile compound that can function effectively in various organic electronic device configurations with different matrix materials
