Dual-Layer Front Cover Airflow Sealing via Asymmetric Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with existing front cover designs lack aesthetic appeal and are prone to external appearance deterioration due to material differences and airflow between cover units, which affects the color and quality of the front surface.
Innovation Solution
A front cover design comprising a first transparent and a second opaque unit, with overlap parts to minimize airflow and prevent deterioration, integrated using a manufacturing mold set for double injection molding, ensuring a cohesive and visually appealing appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a front cover includes a first front cover unit and a second front cover unit with different materials (transparent and opaque), then the aesthetic appeal and color variation are improved, but the external appearance deteriorates due to material differences and airflow between units
Solution Approach 1:
The patent applies asymmetry by designing the first and second front cover units with different material properties (transparent and opaque) and different structural configurations. The first unit has a specific shape while the second unit is designed to cover the rear surface of the first unit, creating an asymmetric arrangement that achieves both aesthetic appeal and functional coverage to prevent airflow-related deterioration.
2Reliability
If the second front cover unit is designed to cover the rear surface of the first front cover unit, then airflow between units is minimized and appearance deterioration is prevented, but the structural complexity increases
Solution Approach 1:
The patent merges the first and second front cover units into a unified front cover assembly where the second unit is integrated to cover the rear surface of the first unit. This combining approach allows the two different material units to work together as a single functional entity, minimizing airflow between them and preventing appearance deterioration while managing structural complexity through integrated design.

AI summary
A front cover of a display device, which includes a first front cover unit and a second front cover unit disposed in a rear of the first front cover, and a manufacturing mold set of the front cover. The front cover minimizes and/or prevents air introduction through gaps between the first front cover unit and the second front cover unit and deterioration of the quality of the external appearance of the front cover thereby.
