Solution Overview

Problem

Typical mobile terminals face challenges in accommodating multiple rear-facing cameras and a fingerprint button due to space constraints, leading to increased size and decreased screen-to-body ratio, which compromises user experience and increases production costs.

Innovation Solution

A screen assembly with a fingerprint module is designed, featuring a transparent cover with a fingerprint opening in the non-display area, allowing the fingerprint module to be partially overlapped with the display module, thereby reducing the device's size and maintaining the screen-to-body ratio, while using abutting and fixing portions for secure mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display screen FPC is disposed below the screen, then the rear-facing cameras can be arranged at the top, but there is insufficient space at the bottom to arrange a fingerprint button

Engineering Contradiction:
Improvearrangement of rear-facing camerasVSAvoidspace at bottom for fingerprint button
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The fingerprint module is positioned in the non-display area at the bottom of the screen, utilizing the vertical space dimension rather than extending the horizontal layout. This allows the fingerprint button to be integrated within the existing screen boundary without requiring additional horizontal space, thereby resolving the space conflict between rear-facing cameras and fingerprint button arrangement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the display screen FPC is disposed at the top of the screen, then the fingerprint button can be arranged at the bottom, but there is insufficient space at the top to arrange multiple rear-facing cameras

Engineering Contradiction:
Improvearrangement of fingerprint buttonVSAvoidspace at top for rear-facing cameras
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The fingerprint module is integrated into the non-display area at the bottom of the screen, utilizing the vertical space dimension rather than extending the horizontal layout. This allows the fingerprint button to be positioned at the bottom without requiring additional horizontal space, thereby resolving the space conflict between fingerprint button and rear-facing cameras arrangement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the length of the lower part of the screen is extended to accommodate both multiple rear-facing cameras and a fingerprint button, then both components can be included, but the size of the terminal device increases and the screen-to-body ratio decreases

Engineering Contradiction:
Improveintegration of multiple rear-facing cameras and fingerprint buttonVSAvoidlength of terminal device
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The fingerprint module is merged with the display module by positioning it within the non-display area of the screen. This integration allows both the fingerprint button and multiple rear-facing cameras to be accommodated within the existing terminal device boundary without extending the overall length, thereby maintaining the screen-to-body ratio while achieving component integration.

Inventive Principle:
Principle #5Merging (Combining)
