Demolding Force Fixture for Nanoimprint Resin Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nanoimprint lithography processes suffer from defects due to the amount of force used during the demolding procedure, which is not optimally controlled, leading to inefficiencies in selecting resins and patterns that minimize defects.
Innovation Solution
A benchtop test fixture system is used to determine the detachment force and work required during demolding, allowing for the evaluation of different resins, patterns, and detachment rates to identify optimal conditions for reduced defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional imprinter mechanisms are used, then imprinting functionality is provided, but the devices are complex and difficult to clean
Solution Approach 1:
The patent extracts and removes the complex traditional imprinter mechanism (including platen, roller, and blade components) entirely, replacing it with a simple stamping mechanism. This extraction eliminates the cleaning difficulties associated with the old mechanism while maintaining imprinting functionality through a simpler design that can be easily wiped clean.
Solution Approach 2:
The patent segments the imprinting function from the complex mechanical mechanism by using a simple stamp that can be easily removed and cleaned separately. The stamping mechanism is divided into discrete, easily cleanable components rather than an integrated complex assembly, allowing for simplified maintenance and cleaning operations.
2Reliability
If conventional packaging materials are used, then packaging functionality is provided, but they do not provide effective anti-counterfeiting protection
Solution Approach 1:
The patent changes the physical and chemical parameters of the packaging material by incorporating security features such as holographic elements, color-shifting inks, and tamper-evident properties into the label material itself. These parameter changes transform ordinary packaging into secure anti-counterfeiting packaging without limiting the range of packaging options available.
Solution Approach 2:
The patent uses composite packaging materials that combine ordinary packaging substrate with security feature layers, creating a multi-layer structure that provides both packaging functionality and anti-counterfeiting protection. The composite nature allows versatility in packaging applications while maintaining security reliability.
3Productivity
If manual quality control methods are used, then inspection is possible, but productivity is reduced due to time-consuming processes
Solution Approach 1:
The patent replaces manual mechanical inspection methods with automated optical scanning and image recognition systems. These electronic systems use cameras and software to automatically detect and verify imprint quality, significantly increasing inspection speed while maintaining or improving measurement precision through consistent automated evaluation criteria.
4Reliability
If secure packaging features are added to packaging materials, then anti-counterfeiting protection is improved, but the materials become more difficult to process
Solution Approach 1:
The patent incorporates security features into the packaging materials during the initial manufacturing process rather than adding them later. Holographic elements and security inks are applied to the label substrate before final assembly, allowing standard processing equipment to handle the materials without modification while maintaining security feature effectiveness.

AI summary
Fixtures and related system and methods are disclosed. In accordance with an implementation, a method includes applying a resin (124) onto a substrate (122) and positioning the substrate over a chuck (110) of a base (108) of a fixture (104). The method also includes moving a mold (118) into engagement with the resin and curing the resin. The method also includes detaching the mold and the resin and, while detaching the mold and the resin, determining a detachment force applied as a function of a distance of detachment between the mold and the resin.
