Window Manufacturing System Indirect Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window layers in display devices are prone to damage during the manufacturing process due to direct contact and pressure, which can lead to scratches and other forms of damage.
Innovation Solution
A window manufacturing system and method that involves using a dummy substrate, a dummy adhesive layer, and a protective cover with a pressurization unit to indirectly press the window layer, preventing direct contact and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If window layers are directly pressed during the manufacturing process, then the window layers can be securely attached, but the surface of the window layers is likely to be damaged
Solution Approach 1:
A dummy substrate is introduced as an intermediary between the pressurization unit and the window layer. The pressurization unit presses the dummy substrate, which in turn indirectly presses the window layer through the adhesive layer, preventing direct contact that would cause surface damage while still achieving secure attachment.
Solution Approach 2:
The pressing function is segmented into multiple components: the pressurization unit, the dummy substrate, the adhesive layer, and the window layer. This segmentation allows the pressing force to be distributed through intermediate layers rather than applied directly to the window layer surface.
2Object-affected harmful factors
If a protective cover is added to prevent window layer damage, then surface damage is prevented, but the device complexity increases
Solution Approach 1:
The dummy substrate serves multiple functions: it acts as a protective cover during pressing to prevent surface damage, serves as a support structure during the manufacturing process, and enables indirect pressing to achieve secure attachment. This multi-functionality reduces the need for separate protective components.
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
The system effectively prevents damage to the window layer by using a protective cover to absorb pressure, ensuring the surface remains undamaged and the window layer is securely attached without scratches.
Implementation Method 1
a dummy adhesive layer on the dummy substrate
Implementation Method 2
a pressurization unit which presses the protective cover to the certain window layer
