Mobile Terminal Bezel-Free Bonding via Lateral Adhesive Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face challenges in minimizing the bezel area while maintaining sufficient bonding force, as the bezel area is increased by the space occupied by adhesives used for bonding the window to the case, which also affects the structural integrity and assembly processes.
Innovation Solution
A mobile terminal design that uses a bonding member extending from the display module's upper surface to its rear surface through the lateral surface, integrating the LCD panel and backlight module, and employing a penetration preventing unit to prevent adhesive penetration between layers, allowing for a bezel-free bonding surface and reduced assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to bond the window to the case, then bonding strength is achieved, but the bezel area is increased
Solution Approach 1:
The bonding member extends from the upper surface of the display module through the lateral surface to the rear surface, utilizing the lateral dimension to provide bonding path without occupying front bezel area. This dimensional transition allows adhesive bonding while minimizing visible bezel width.
Solution Approach 2:
The bonding member acts as an intermediary element that bridges the window and display module, and subsequently connects to the case. This intermediate structure enables force transmission and bonding while being positioned in non-visible areas, effectively decoupling the bonding function from the visible bezel area.
2Stability of the object's composition
If adhesive is used for bonding, then structural integrity is maintained, but assembly complexity increases
Solution Approach 1:
The bonding member integrates multiple functions into a single component: it bonds the window to the display module, provides structural support, and connects to the case. This merging of bonding and structural functions into one element simplifies assembly compared to using separate adhesive layers and support structures.
Solution Approach 2:
The bonding member serves multiple purposes simultaneously: it acts as an adhesive carrier, a structural reinforcement element, and a mechanical connector between components. This multi-functionality reduces the number of separate parts needed, thereby simplifying the overall assembly process while maintaining structural integrity.
