Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charge carrier injection zone is placed adjacent to lateral surface of semiconductor cylinder with organic material, then efficiency of charge carrier penetration and recombination in organic material is improved, but device complexity increases due to specific geometric configuration requirements
Solution Approach 1:
The patent transitions from conventional planar or bulk semiconductor structures to a cylindrical geometry where the charge carrier injection zone is positioned at the lateral surface rather than in a planar configuration. This dimensional change enables charge carriers to be injected directly adjacent to the organic material interface, dramatically improving penetration efficiency and recombination rates while maintaining manageable device complexity through the symmetry of the cylindrical form.
2Productivity
If direct electronic contact is made between charge carrier injection zone and organic material, then charge carrier transfer efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent introduces an intermediary mechanism where charge carriers are injected into the semiconductor cylinder and diffuse through the bulk material to reach the organic material layer at the lateral surface. This diffusion-based transport mechanism serves as an intermediary process that achieves efficient charge carrier transfer without requiring direct physical contact or precisely controlled interfaces, thereby reducing manufacturing precision requirements while maintaining high transfer efficiency.
3Productivity
If semiconductor cylinder diameter is reduced to enhance charge carrier diffusion to lateral surface, then charge carrier penetration efficiency is improved, but device power output decreases
Solution Approach 1:
The patent applies local quality by creating a specific structural configuration where the charge carrier injection zone is positioned at the lateral surface of the cylinder, adjacent to the organic material. This localized arrangement ensures that charge carriers are injected directly where they are needed for efficient diffusion and recombination, maximizing penetration efficiency without requiring a reduction in overall device dimensions or power output capability.
