Moisture Resistant Pad With Closed Undulation Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal panels are prone to polarizer shrinkage due to excessive humidity, which can lead to functional failure, especially during transportation and storage in high-humidity environments.
Innovation Solution
A moisture-resistant pad with a closed-loop undulation structure is designed to prevent water vapor from reaching the panel, featuring annular projections and recesses that create a barrier around the panel, isolating it from external moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flat packaging is used, then the structure is simple and easy to manufacture, but water vapor can penetrate from all directions causing polarizer shrinkage
Solution Approach 1:
The packaging structure is segmented into multiple functional regions: a central depressed region for housing the liquid crystal panel, annular projections forming undulation structures that create blocking channels, and edge regions with increased thickness. This segmentation divides the packaging into moisture-blocking zones and product-protection zones, effectively preventing water vapor penetration while maintaining structural clarity.
Solution Approach 2:
The invention transitions from a traditional two-dimensional flat packaging surface to a three-dimensional structure with undulation features. The annular projections create vertical blocking channels that extend into the packaging thickness, adding a depth dimension to moisture resistance. This dimensional change transforms the packaging from a passive flat barrier to an active multi-layer blocking system.
2Reliability
If moisture resistant constructions are added to block water vapor, then moisture resistance improves, but the packaging structure becomes more complex
Solution Approach 1:
The moisture-resistant packaging utilizes the flexible properties of the foam material to create undulation structures through molding. The annular projections and depressed regions are formed as integrated features of the foam sheet, allowing the material to conform to the required three-dimensional shape. This approach maintains ease of manufacture by using standard foam molding techniques while achieving complex moisture-blocking geometry.

AI summary
A moisture resistant pad for a liquid crystal panel, including at least one moisture resistant construction including a central region and an edge region disposed around the central region, wherein the edge region includes a first undulation structure disposed around the central region, the first undulation structure being a closed structure for blocking water vapor out of the central region. In the moisture resistant pad for a liquid crystal panel, channels formed within a surface of a product that needs to be moisture resistant are isolated from the external environment so that water vapor in the external environment cannot contact the product surface through the channels. As a result, the pad has good moisture resistance, suitable in transportation environments or in packaging container environments.
