Solution Overview
Problem
Existing imprinting technologies face challenges in easily replacing imprinting materials and removing impurities from the resin tank and supply path, leading to defective patterns and wastage of expensive resins.
Innovation Solution
A detachable application device with a container unit, ejecting unit, and storage unit that allows for easy replacement and filtration of imprinting materials, using a resin circulating device to supply new resin and remove impurities, ensuring efficient utilization of the nozzle and minimizing resin wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the imprinting material is supplied through a supply path from a tank to the ejection hole, then the imprinting material can be supplied to the substrate, but the imprinting material cannot be easily replaced and impurities cannot be removed from the supply path
Solution Approach 1:
The application device is divided into a tank unit containing the imprinting material and a separate ejection unit with ejection holes. This segmentation allows the tank to be detached and replaced independently from the ejection unit, enabling easy material replacement without disassembling the entire device. The supply path can be isolated by closing valves when the tank is removed, preventing resin wastage.
Solution Approach 2:
The tank unit is designed to be extractable from the ejection unit. When material replacement is needed, the entire tank unit can be removed from the device, allowing access to the supply path for cleaning and maintenance. This extraction capability enables easy removal of impurities from the supply path while maintaining the ejection functionality.
2Manufacturing precision
If the tank and supply path are cleaned to remove impurities, then the imprinting quality improves, but the process time and resin wastage increase
Solution Approach 1:
The tank unit is designed with pre-configured connection interfaces and quick-connect mechanisms that enable rapid attachment and detachment. Valves are pre-positioned to automatically close when the tank is removed, preventing resin leakage. This preliminary design of the disconnection mechanism allows for fast material replacement and cleaning operations, reducing the time required for maintenance while ensuring printing quality.
3Adaptability or versatility
If the application device is integrated with fixed tank and ejection unit, then the structure is simple, but the imprinting material cannot be easily replaced
Solution Approach 1:
The ejection unit is designed with universal connection interfaces that can accommodate different tank units. The same ejection unit with its ejection holes and valve mechanisms can work with multiple tank units containing different imprinting materials. This multi-functionality allows for easy material replacement without requiring different ejection units, while maintaining a relatively simple overall structure through standardized connections.
