Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chemical liquid supply apparatuses face challenges in uniformly distributing and classifying nanorods for quantum nano emitting diode (QNED) displays, leading to inconsistent display quality due to varying nanorod sizes and the need for frequent replacement of classification components.
Innovation Solution
A chemical liquid supply apparatus with a classification chip and power supply that uses dielectrophoresis to collect and release nanorods of a specific size, integrated with a circulation pipe system and discharge pipes to ensure uniform nanorod distribution and prevent foreign matter accumulation, allowing for continuous operation without replacing the classification chip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a classification chip is used to separate nanorods by size, then nanorod size uniformity is improved, but the classification chip requires frequent replacement due to foreign matter accumulation
Solution Approach 1:
The patent implements a mechanism to recover and reuse the classification chip by periodically flushing it with pure solvent through the discharge pipe, removing accumulated foreign matter and restoring its classification function without replacement
Solution Approach 2:
The system performs self-maintenance by using the circulation pipe and discharge pipe to automatically flush the classification chip with pure solvent, eliminating the need for manual cleaning or replacement operations
2Stability of the object's composition
If nanorods are collected and released continuously, then display quality consistency is improved, but foreign matter may accumulate on the classification chip
Solution Approach 1:
The patent enables continuous operation by circulating chemical liquid through the circulation pipe, collecting and releasing nanorods continuously, while periodically flushing the classification chip to prevent foreign matter accumulation
Solution Approach 2:
The system monitors nanorod collection and release processes, adjusting the flushing mechanism to remove foreign matter that accumulates during continuous operation, maintaining stable display quality
