Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nanoimprinting processes face challenges in maintaining product structure integrity during film separation, leading to reduced yield due to inadequate adaptation to resist and parameter changes, resulting in potential damage to the imprinted product.
Innovation Solution
The imprinting apparatus incorporates a lifting and pressing mechanism with a transfer module and film separation module, allowing the imprinting roller to apply versatile and flexible pressure through weight and mechanical pressure, and includes adjustable load cells and sensors for precise control, enabling the transfer film to be separated at optimal angles to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transfer film is separated by lifting and pulling it slowly, then the separation process is simple to operate, but the imprinted product structure may be damaged due to inadequate adaptation to resist and parameter changes
Solution Approach 1:
The patent implements a lifting and pressing mechanism that dynamically adjusts the pressure applied to the imprinting roller during film separation. The mechanism transitions from a static pulling operation to a dynamic process where pressure is actively controlled and adjusted based on real-time conditions, allowing adaptation to resist and parameter changes while maintaining product structure integrity
Solution Approach 2:
The patent changes the pressure parameter during film separation by using a lifting and pressing mechanism. The mechanism applies variable pressure (from 0.1 MPa to 10 MPa) during the separation process, transforming the constant-force pulling method into a controlled variable-pressure process that adapts to different resist and parameter conditions, thereby preventing product damage
2Productivity
If a lifting and pressing mechanism is used to apply versatile pressure, then the imprinting yield and control precision are improved, but the device complexity increases
Solution Approach 1:
The lifting and pressing mechanism is designed to perform multiple functions: it can lift the imprinting roller, apply controlled pressure, and maintain position during film separation. This multi-functional design consolidates several operations into a single mechanism, improving imprinting yield while managing device complexity through functional integration
Solution Approach 2:
The patent incorporates sensors that detect the position and pressure parameters during film separation, providing feedback to the control system. This feedback mechanism enables precise control of the lifting and pressing operations, ensuring optimal pressure application and improving imprinting yield through real-time adjustments

Function Achieved in This Case
This solution enhances the yield and operating convenience of the imprinting process by ensuring the transfer film is separated without damaging the imprinted product, allowing for more versatile pressure application and precise control over the imprinting process.
Implementation Method 1
the transfer film is pressed by a weight of the imprinting roller
Implementation Method 2
the lifting and pressing mechanism pressurizes the imprinting roller, the imprinting roller contacts the transfer film, and the transfer film is pressed by a combination of the weight of the imprinting roller and a pressure of the lifting and pressing mechanism
