Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adhesive force between a curved display apparatus window and its panel member is degraded during manufacturing, leading to defects in the display apparatus.
Innovation Solution
An apparatus and method involving a first mold for the window, a second mold with a variable shape for the panel member, and a guide roller to maintain tension, ensuring proper bonding from the center to the ends of the panel member, using silicone and a driver for relative movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical apparatus and method are used to attach a panel member to a curved window, then the manufacturing process is simple, but the adhesive force between the curved portion of the window and the panel member is degraded and defects occur
Solution Approach 1:
A guide roller is introduced as an intermediary component between the molding press and the panel member. The guide roller maintains tension on the panel member during the bonding process, ensuring uniform adhesive force distribution across the curved window surface. This intermediary device prevents defects like bubbles and delamination without requiring complex multi-component apparatus
Solution Approach 2:
The guide roller is designed to be rotatable rather than fixed, allowing it to dynamically adapt to the curvature of the window and the tension requirements of the panel member. This dynamic component maintains optimal contact and tension throughout the bonding process, improving adhesive force while keeping the apparatus relatively simple
2Reliability
If the panel member is bonded to the curved window without maintaining tension, then the bonding process is fast, but bubbles are generated and adhesive force is degraded
Solution Approach 1:
The guide roller serves as a mediator that maintains tension on the panel member during bonding. By introducing this simple intermediary component, the process achieves high bonding quality without significantly slowing down production, as the roller passively maintains tension rather than requiring active control mechanisms
Solution Approach 2:
The guide roller is positioned to engage the panel member before the bonding process begins, pre-establishing the necessary tension. This preliminary action ensures that when bonding commences, the panel member is already in the correct tension state, preventing bubble formation without requiring additional time during the actual bonding operation
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 approach prevents bubble formation and enhances the bonding quality between the window and panel member, reducing defects and improving the overall quality of the display apparatus.
Implementation Method 1
a guide roller on the first mold. The second mold faces the first mold and has a variable shape. The guide roller is rotatable and is configured to maintain tension in the panel member as the window and the panel member are bonded to each other
Implementation Method 2
The second mold may include silicone
