Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic device components and assembly methods limit the active display area and user experience due to large bezels and structural constraints, inhibiting performance and aesthetic appeal.
Innovation Solution
The design incorporates a light guide with a light source, a light-blocking component, and a translucent tab to maximize the active display area by minimizing bezels, using a transparent cover and optical films to enhance light diffusion and support, while maintaining performance and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If traditional components and assembly methods are used, then structural support and protection are provided, but the active display area is limited due to large bezels
Solution Approach 1:
The patent extracts the light-blocking function from traditional large bezel structures and concentrates it into a small light-blocking component positioned only at the light source location. This removes unnecessary structural elements while maintaining the light-blocking function, thereby maximizing the active display area without compromising structural support.
Solution Approach 2:
The display assembly is segmented into distinct functional components: a light guide plate, a small light-blocking component, a translucent tab, and optical films. This segmentation allows each component to be optimized for its specific function while minimizing overall structural footprint, enabling larger active display area with reduced bezel size.
2Ease of operation
If traditional methods of device assembly are used, then physical support and protection are provided, but user experience is limited due to large bezels
Solution Approach 1:
The patent applies local quality by providing light-blocking properties only where absolutely necessary (at the light source location) rather than across the entire bezel area. The translucent tab provides localized support and film guidance only at critical expansion/contraction zones, allowing maximum display area while maintaining user experience through precise, targeted structural elements.
3Area of moving object
If bezel size is reduced to maximize active display area, then user-facing display area is increased, but structural support and film guidance during expansion and contraction may be compromised
Solution Approach 1:
The translucent tab serves as an intermediary element between the light-blocking component and the optical films. It provides localized support and guidance for the films during display expansion and contraction, ensuring reliability without requiring large bezel structures. The tab acts as a mediator that maintains film integrity while allowing maximum display area.
Solution Approach 2:
The patent transitions from traditional two-dimensional bezel structures to a three-dimensional configuration with the translucent tab extending vertically from the light-blocking component. This dimensional change allows the tab to provide film guidance and support in the vertical dimension while minimizing horizontal footprint, thereby maximizing active display area without compromising structural reliability.

Function Achieved in This Case
This configuration maximizes the user-facing active display area, reduces bezel size, and maintains or improves display performance by optimizing the structural components and optical properties, ensuring minimal interference and additional guidance for the films during expansion and contraction.
Implementation Method 1
a light guide, a light source positioned at an end of the light guide... The light guide can include a transparent plate that defines a mixing region for light emitted from the light source
Implementation Method 2
a translucent portion that extends from the light-blocking component and overlies the light guide... The translucent portion can include a diffusive film
