Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conducting polymers use conjugated multiple bond systems and fluorocarboxylic acid functional groups to achieve conductivity, then electrical conductivity is improved, but processability and mechanical properties deteriorate
Solution Approach 1:
The invention extracts and removes the conjugated multiple bond systems from the polymer structure, replacing them with saturated carbon backbones. This extraction eliminates the structural requirements that caused poor processability while maintaining conductivity through alternative metal carboxylate coordination mechanisms
Solution Approach 2:
The invention changes the chemical parameter of the polymer backbone from unsaturated (conjugated) to saturated (single bonds), fundamentally altering the material's properties. This parameter change allows the polymer to achieve conductivity through metal coordination rather than electron delocalization, improving processability while maintaining electrical function
2Reliability
If conducting polymers use conjugated multiple bond systems and fluorocarboxylic acid functional groups to achieve conductivity, then electrical conductivity is improved, but mechanical properties deteriorate
Solution Approach 1:
The invention extracts the conjugated bond system that provided conductivity and replaces it with a saturated backbone combined with metal carboxylate groups. This removal of the rigid conjugated structure eliminates the source of mechanical brittleness while maintaining electrical conductivity through alternative coordination chemistry mechanisms
Solution Approach 2:
The invention creates a composite structure combining saturated carbon backbone polymers with metal carboxylate functional groups. This composite approach integrates the mechanical stability of saturated polymers with the electrical conductivity provided by metal coordination, achieving both improved mechanical properties and maintained conductivity
3Reliability
If conducting polymers use conventional structures to achieve conductivity, then electrical conductivity is improved, but internal resistance increases
Solution Approach 1:
The invention changes the conductivity mechanism parameter from electron delocalization in conjugated systems to ion conduction through metal carboxylate coordination. This parameter change reduces internal resistance by providing alternative conduction pathways that are less susceptible to the limitations of conjugated bond systems
