Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensing methods for liquid crystal display panels, such as screen-printing and seal dispensing, face challenges in efficiently accommodating substrates of varying sizes and require significant manual intervention and increased processing time, leading to reduced productivity and potential alignment defects.
Innovation Solution
A complex dispensing apparatus and method that integrates the formation of silver paste and sealant using a single apparatus, allowing for in-line dispensing on a substrate with multiple dispensers and nozzles, enabling simultaneous formation of seal patterns and silver dots across the substrate, regardless of size or model changes, without the need for reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate dispensing apparatus are used for silver paste and sealant, then each material can be dispensed with dedicated equipment, but the fabrication process becomes complex and productivity decreases
Solution Approach 1:
The patent combines separate dispensing apparatus for silver paste and sealant into a single integrated complex dispensing apparatus. This merging eliminates the need for multiple separate equipment pieces and reduces fabrication process complexity while maintaining reliable dispensing quality through unified control and coordination of multiple dispensing units.
Solution Approach 2:
The complex dispensing apparatus is designed with multi-functionality to handle both silver paste and sealant dispensing operations. The apparatus includes multiple dispensing units that can be configured to dispense different materials, making a single apparatus capable of performing functions previously requiring separate dedicated equipment.
2Manufacturing precision
If the dispensing apparatus is reassembled for different substrate sizes, then dispensing accuracy can be maintained, but processing time increases and productivity decreases
Solution Approach 1:
The dispensing apparatus incorporates dynamic, adjustable components that can be reconfigured for different substrate sizes without requiring full reassembly. The apparatus maintains dispensing accuracy through adjustable positioning mechanisms and programmable control systems that adapt to various substrate dimensions, eliminating time-consuming manual reassembly operations.
Solution Approach 2:
The apparatus uses programmable parameters and control settings that can be changed to accommodate different substrate sizes. By modifying operational parameters such as dispensing position, speed, and pattern through software control rather than physical reassembly, the system maintains precision while significantly reducing setup time and improving productivity.
3Adaptability or versatility
If manual intervention is used for dispensing operations, then flexibility in handling different substrates is achieved, but processing time increases and alignment defects may occur
Solution Approach 1:
The dispensing apparatus incorporates automated control systems that enable self-service operation for handling different substrate types. The system can automatically detect substrate characteristics, adjust dispensing parameters, and execute dispensing operations without manual intervention, maintaining flexibility while dramatically reducing processing time and eliminating alignment defects caused by manual handling.
Solution Approach 2:
The apparatus includes feedback mechanisms that automatically detect substrate position, orientation, and characteristics, then adjust dispensing operations accordingly. This closed-loop control system provides the adaptability previously requiring manual intervention while eliminating the time loss and alignment errors associated with manual operations through automated real-time adjustments.
