Molded Body Assembly Pattern Transfer and Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to minimize the risk of damage to fine transferred patterns on molded bodies during transportation and incorporation into products, such as smartphones, where existing nanoimprint technologies fail to protect the patterns effectively.
Innovation Solution
An apparatus is developed that includes a to-be-molded body holder, a mold holder, a transfer unit, and a cutting unit, which allows for the transfer of a fine transfer pattern from an uncut mold to a to-be-molded body, followed by cutting the mold to form a sheet-like mold that adheres to the molded body, protecting the pattern and allowing for easy removal when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mold is separated from the to-be-molded body after transferring the pattern, then the transferred pattern can be obtained, but the transferred pattern may be damaged during transportation or incorporation
Solution Approach 1:
The mold is kept attached to the to-be-molded body immediately after pattern transfer, before any transportation or incorporation operations occur. This preliminary attachment action protects the transferred pattern during subsequent handling and transportation processes, preventing damage that would occur if the mold were separated earlier.
Solution Approach 2:
The invention employs a thin-film mold that maintains flexibility while providing protection. The thin-film nature allows the mold to conform to the to-be-molded body while the attached state provides structural protection for the transferred pattern during transportation and incorporation into products.
2Reliability
If the mold remains attached to protect the pattern, then pattern damage is minimized, but the mold needs to be removable when the product is used
Solution Approach 1:
The mold attachment system is designed to be dynamic rather than permanent. The mold can be easily attached immediately after pattern transfer and then readily removed when needed for product use, providing temporary protection only when required without creating permanent complexity in the product structure.
Solution Approach 2:
The attachment of the mold to protect the pattern is a preliminary, temporary measure taken only during transportation and incorporation. Once the protective function is fulfilled, the mold is removed, avoiding permanent complexity in the final product design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively minimizes the risk of damage to the transferred pattern by maintaining adhesion between the mold and the molded body during transportation and incorporation, ensuring the pattern's integrity until it is exposed or used as a product.
Implementation Method 1
nanoimprint technologies have been studied and developed... in which the template is pressed against a to-be-molded piece with a predetermined pressure to transfer the transfer pattern formed on the template
Implementation Method 2
the molding material 313 is irradiated with ultraviolet light to be cured
Implementation Method 3
the mold is adhering to the molded body after the transferring, the adhering of the mold to the molded body is maintained, to protect a fine transferred pattern formed in the molded material
