Bracket Corner-Removing Portion for Fingerprint Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices face challenges in providing secure encryption and aesthetics due to the exposure of fingerprint identification assemblies, which occupy screen space and compromise water resistance and appearance.
Innovation Solution
A bracket with a corner-removing portion for mounting a fingerprint identification assembly, combined with a cover plate assembly featuring a mounting hole and annular base, allows for increased adhesive bonding and improved structural stability and aesthetics by filling gaps with glue, enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fingerprint identification assembly is exposed outside the outer surface of the mobile phone, then the fingerprint identification function is accessible, but the screen space is occupied and the appearance aesthetics deteriorates
Solution Approach 1:
The fingerprint identification assembly is moved from the traditional horizontal placement on the screen surface to a vertical placement within the side bracket structure. This dimensional change allows the fingerprint sensor to be positioned in the thickness direction of the mobile phone, effectively utilizing the side space rather than occupying screen real estate while maintaining full accessibility.
2Ease of operation
If the fingerprint identification assembly is exposed outside the outer surface, then the fingerprint function is accessible, but the water proof performance deteriorates
Solution Approach 1:
The fingerprint identification assembly is nested within the bracket structure, which itself is embedded in the mounting hole of the cover plate. This nested arrangement creates multiple protective layers, with the bracket serving as an additional barrier that enhances water and dust resistance while keeping the fingerprint sensor accessible through the designed opening.
3Stability of the object's composition
If the bracket outer circumferential wall is positioned close to the cover plate inner circumferential wall, then the structural compactness is improved, but the adhesive bonding area is insufficient
Solution Approach 1:
The bracket is designed with a corner-removing portion at specific locations where the outer circumferential wall would otherwise be close to the cover plate. This localized modification creates concentrated adhesive bonding areas at the corners, providing sufficient bonding strength in critical regions while maintaining overall structural compactness in other areas.
4Strength
If the corner-removing portion is provided in the bracket outer circumferential wall, then the adhesive bonding area is increased, but the bracket structure complexity increases
Solution Approach 1:
The corner-removing portion is designed as a simple geometric modification that segments the outer circumferential wall to create bonding zones. This segmentation approach increases adhesive bonding area by creating distinct corner regions for glue application, while the overall bracket structure remains relatively simple and easy to manufacture.

AI summary
The present disclosure relates to a bracket for mounting a fingerprint identification assembly, a cover plate assembly and a terminal. The bracket includes an outer circumferential wall; an inner circumferential wall opposite to the outer circumferential wall; and a bottom wall coupled to the outer circumferential wall. The outer circumferential wall has a corner-removing portion approaching towards the inner circumferential wall.
