L-Shaped Bracket for Bezel-Less Display Overlay Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to attach overlays to electronic displays with minimal or no bezel, where traditional attachment systems fail due to lack of space and the need for non-obstructive solutions that facilitate easy installation and removal.
Innovation Solution
The system employs L-shaped or straight brackets with pressure-sensitive adhesive and magnetic attracting members to securely attach overlays to electronic displays without obstructing the viewing area, utilizing materials like plastic or metal and optically clear adhesives for a user-friendly and versatile attachment method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional plastic tabs with adhesive stripes are used to attach overlays, then the overlay can be secured to the display, but the attachment system obstructs the viewing area and requires a raised bezel perimeter
Solution Approach 1:
The bracket transitions from a 2D surface-mounted tab to a 3D L-shaped structure that extends perpendicular to the display surface. This dimensional change allows the attachment mechanism to be positioned in the depth dimension rather than occupying the viewing area on the display surface.
Solution Approach 2:
The attachment system is divided into separate functional components: the bracket (structural support), the attracting member (magnetic attachment), and the adhesive layer (bonding). This segmentation allows each component to be optimized for its specific function while minimizing overall space requirements.
2Adaptability or versatility
If traditional plastic tabs with adhesive stripes are used to attach overlays, then the overlay can be secured to the display, but the system becomes incompatible with bezel-less displays having no raised perimeter
Solution Approach 1:
The magnetic attracting member is concentrated at specific locations (corners or edges) rather than distributed across the entire bracket. This localized magnetic attachment provides sufficient holding force while maintaining compatibility with bezel-less displays, as the magnetic force acts at discrete points rather than requiring a continuous raised perimeter.
Solution Approach 2:
The mechanical tab-and-slot system is replaced with a magnetic field-based attraction system. This substitution eliminates the need for mechanical interlocking features that require raised bezels, allowing the overlay to be securely attached to flat, bezel-less displays through magnetic force alone.
3Ease of operation
If magnets are placed on the bracket for attachment, then the overlay can be easily attached and removed, but the magnetic components may interfere with display functionality
Solution Approach 1:
A non-magnetic barrier layer (such as plastic or metal film) is positioned between the magnetic attracting member and the display overlay. This thin film shields the display components from magnetic fields while allowing the magnetic attachment function to operate effectively, thus preventing interference with display functionality.
