Integrated Pouch with Metallic Base and Soft Inner Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective films for display panels are prone to contamination and scratching during manufacturing, storage, and transfer due to direct contact and adhesion processes, leading to inefficiencies and surface property variations.
Innovation Solution
A protective film-integrated pouch with a metallic base layer, a nylon outer surface layer, and a mixed polyethylene inner surface layer is developed, where the inner surface layer is softer than the display panel to prevent scratches and is integrated with an antistatic layer to minimize static electricity, ensuring contamination-free and efficient protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective film is attached to the display panel surface using adhesion process, then the protective film can protect the display panel, but the adhesion process requires accurate operator attention and may cause contamination and scratches
Solution Approach 1:
The protective film is integrated with the pouch to form a single unified structure. The pouch body is formed by laminating a base layer, outer surface layer, and inner surface layer, where the inner surface layer is directly attached to the display panel without requiring separate adhesion operations. This merging eliminates the need for separate protective film attachment processes.
Solution Approach 2:
The pouch structure itself provides the protective function. The inner surface layer of the pouch is designed to directly contact the display panel and provide protection, eliminating the need for separate protective films and adhesion operations. The pouch structure serves both containment and protection functions simultaneously.
2Reliability
If a protective film directly contacts the display panel, then protection is provided, but components of the protective film diffuse into the display panel causing contamination and physical property variation
Solution Approach 1:
The inner surface layer of the pouch is specifically designed with different material properties compared to the outer surface layer. It uses a softer resin material with lower hardness than the display panel surface, creating a compliant interface that prevents scratching while maintaining protection. This localized quality differentiation addresses the contamination issue at the critical contact interface.
Solution Approach 2:
The pouch is constructed as a composite structure with multiple layers: a base layer for structural integrity, an outer surface layer for durability, and an inner surface layer for protection. The inner surface layer uses a soft resin composite material that is harder than the display panel surface to prevent scratching while softer than the panel to avoid contamination through diffusion.
3Adaptability or versatility
If protective film and pouch are separated, then each can be optimized independently, but operation efficiency deteriorates due to additional handling steps
Solution Approach 1:
The protective film function is merged into the pouch structure by making the inner surface layer an integral part of the pouch. This eliminates the need for separate protective film handling, attachment, and removal operations, thereby improving operation efficiency while maintaining design flexibility through the multi-layer composite structure.
