Aligned Display Protection Member Side Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the assembly of display devices, the side surfaces of anti-scattering films and glass windows often misalign, leading to protrusions and reduced process efficiency due to assembly tolerances, and existing methods require direct cutting of glass substrates which can compromise their strength.
Innovation Solution
A protection member for display devices is designed with a glass substrate coated by a functional layer and coupled with film and additional layers, where the side surfaces of all layers are aligned in the same plane without direct cutting of the glass, using a method that includes forming a coating layer on the glass substrate and sequentially stacking coupling and film layers, and cutting these layers together to maintain the glass's strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-scattering films are attached onto glass windows to prevent scattering of glass splinters, then safety is improved, but assembly tolerance increases due to misalignment of side surfaces
Solution Approach 1:
The patent combines the glass substrate, coating layer, coupling layer, and film layer into a single integrated protection member structure. The side surfaces of all layers are formed to be aligned in the same plane, eliminating the need for separate alignment operations and reducing cumulative assembly tolerance. This merging approach maintains the safety function of preventing glass splinter scattering while achieving precise side surface alignment.
2Manufacturing precision
If glass substrates are directly cut to align side surfaces, then manufacturing precision is improved, but strength of glass is reduced
Solution Approach 1:
The patent performs the side surface alignment action on the coating layer, coupling layer, and film layer before final assembly, forming their side surfaces to be aligned in the same plane. This preliminary action eliminates the need for subsequent cutting of the glass substrate, thereby maintaining both manufacturing precision and glass strength. The alignment is achieved through the structure design of the layered components rather than post-assembly cutting.
3Ease of manufacture
If multiple layers are stacked with loose alignment, then ease of manufacture is improved, but protruding portions occur resulting in poor assembly
Solution Approach 1:
The patent introduces asymmetric design elements through the side surface alignment structure, where the coating layer, coupling layer, and film layer are specifically configured to have side surfaces aligned in the same plane. This asymmetric configuration prevents protruding portions from forming during stacking, ensuring smooth external surfaces while maintaining ease of manufacture through the predetermined structural design.
