Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal dropping devices are inefficient due to the need for multiple movements of a single dropping head, resulting in prolonged manufacturing time and uneven liquid crystal arrangements on the substrate.
Innovation Solution
A liquid crystal dropping device with two dropping heads connected to a single nozzle, utilizing a driver to eject liquid crystal, and a corrosion-resistant connecting pipe to facilitate even distribution, reducing the volume of each droplet and enhancing manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single dropping head is used to drop liquid crystal onto the substrate, then the device structure is simple, but the manufacturing time is prolonged and productivity is low
Solution Approach 1:
The patent divides a single dropping head into multiple dropping heads (at least two) that share a common nozzle. Each dropping head operates independently to drop liquid crystal onto different positions of the substrate simultaneously, thereby increasing productivity without requiring multiple complete sets of nozzles and drivers.
2Loss of time
If a single dropping head moves multiple times to cover all dropping points, then the device structure is simple, but the manufacturing time is prolonged
Solution Approach 1:
The patent segments the dropping function into multiple parallel dropping heads, allowing simultaneous dropping at multiple positions. This eliminates the need for sequential movement and dropping operations, significantly reducing manufacturing time and improving productivity.
3Manufacturing precision
If liquid crystal is ejected from a single nozzle to multiple dropping heads, then the device complexity is reduced, but the liquid crystal distribution may become uneven
Solution Approach 1:
The patent introduces a corrosion-resistant connecting pipe as an intermediary component between the nozzle and multiple dropping heads. This connecting pipe is specifically designed to be corrosion-resistant to prevent liquid crystal residue from corroding the pipe, thereby maintaining consistent liquid crystal flow and droplet volume across all dropping heads, which ensures uniform liquid crystal arrangement on the substrate.
4Manufacturing precision
If the connecting pipe is made of corrosion-resistant material, then the liquid crystal distribution remains uniform, but the device complexity increases
Solution Approach 1:
The patent specifies using corrosion-resistant material for the connecting pipe, which can be a disposable or replaceable component. This approach maintains manufacturing precision by preventing corrosion-related variations in droplet volume, while the simplicity of using standard corrosion-resistant materials (such as specific plastics or metals) keeps the overall device complexity manageable.
