Mobile Terminal Medium Casing for Wide Visual Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals have a wide rim frame due to the structure of their backlight modules, which limits the visual area and increases production complexity and costs.
Innovation Solution
A mobile terminal medium casing with a receiving groove housing a reflective sheet, light guiding plate, and optical sheet group, integrated with a light source assembly, which eliminates the need for a separate back plate and frame sealing glue, allowing for a thinner design and increased visual area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional backlight module structure with back plate, adhesive frame, light source assembly, reflective sheet, light guiding plate and optical sheet group is used, then the backlighting function is achieved, but the rim frame becomes wide and the visual area is reduced
Solution Approach 1:
The patent merges the back plate and adhesive frame into a single integrated casing body. The casing body directly receives and secures the light guiding plate and optical sheets without requiring a separate back plate and adhesive frame, thereby eliminating the need for these additional components and reducing the overall rim frame width.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the traditional backlight module structure. By removing the back plate and adhesive frame, the design achieves a more compact structure with reduced rim frame width while maintaining the essential backlighting functionality through the integrated casing body.
2Ease of manufacture
If a traditional backlight module with multiple separate components is used, then the backlighting function is achieved, but the production process becomes complex and costs increase
Solution Approach 1:
The patent combines multiple separate components (back plate and adhesive frame) into a single integrated casing body. This reduction in component count simplifies the production process by reducing the number of assembly steps and materials required, thereby improving ease of manufacture and reducing production costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the rim frame of the mobile terminal, enhances the visual area, simplifies the production process, and lowers manufacturing costs while maintaining effective backlighting for the display panel.
