Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive polymers are doped to increase electrical conductivity, then electrical conductivity is improved, but solubility and light transmittance deteriorate
Solution Approach 1:
The patent combines conductive polymer particles with insulating polymer matrix to create a composite material. The insulating polymer compensates for the loss of solubility caused by doping, while the conductive polymer provides electrical conductivity. This composite structure allows the material to maintain both electrical functionality and processability.
Solution Approach 2:
The patent modifies the chemical structure of conductive polymers by introducing soluble side chains or modifying the polymer backbone. This parameter change allows the doped conductive polymer to maintain solubility in common solvents while retaining its electrical conductivity properties, resolving the contradiction between conductivity enhancement and solubility maintenance.
2Reliability
If conductive polymers are doped to increase electrical conductivity, then electrical conductivity is improved, but light transmittance deteriorates
Solution Approach 1:
The patent uses transparent conducting oxides (TCO) such as ITO or IZO as the conductive component. These materials have localized conductivity properties that allow electrons to move freely in certain directions while maintaining optical transparency in the visible range. This local quality differentiation enables simultaneous achievement of high electrical conductivity and light transmittance.
Solution Approach 2:
The patent changes the optical parameters of the conductive material by selecting TCOs with specific band gap energies that are larger than the visible light range. This parameter change allows the material to be electrically conductive while remaining optically transparent, resolving the contradiction between conductivity and light transmittance.
3Strength
If conventional conductive polymers are used, then flexibility is maintained, but electrical conductivity is insufficient
Solution Approach 1:
The patent creates a composite where conductive polymer particles are dispersed in a flexible insulating polymer matrix. This structure combines the high electrical conductivity of the conductive polymer with the mechanical flexibility and processability of the insulating polymer, allowing the material to be bent and shaped while maintaining electrical functionality.
