Solution Overview

Problem

Full-screen mobile phones face space constraints due to the presence of front lens assemblies, earpiece assemblies, and light-ray sensors on the front side face, limiting the increase in screen ratio and visual experience.

Innovation Solution

A mobile terminal design featuring a housing with a receiving groove on its top face, allowing a mounting frame with cameras to extend or retract, keeping the cameras exposed or hidden without occupying screen space, and utilizing a slidable device with a driving mechanism to manage camera positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If front lens assembly, earpiece assembly, and light-ray sensor are arranged on the front side face, then these components can function, but the screen ratio is limited

Engineering Contradiction:
Improvecomponent functionalityVSAvoidscreen ratio
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent moves the camera assembly from the front side face (2D surface) to the top edge of the housing, utilizing the third dimension (depth/edge space). This allows the camera to function while occupying minimal front screen area, thereby increasing the screen ratio without compromising component functionality.

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

Solution Approach 2:

The camera assembly is extracted from the traditional front face location and repositioned to the top edge. This extraction removes the obstruction from the front screen area, enabling full-screen display while maintaining camera functionality through the repositioned assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If camera assembly is placed on the front side face, then camera function is available, but visual experience is reduced due to space occupation

Engineering Contradiction:
Improvecamera functionalityVSAvoidvisual experience
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

By relocating the camera assembly to the top edge of the housing rather than the front face, the patent utilizes vertical edge space instead of horizontal screen space. This dimensional shift preserves camera functionality while eliminating the visual obstruction, thereby enhancing the visual experience and full-screen effect.

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

3Device complexity

If fixed camera position is used, then structure is simple, but screen ratio cannot be increased

Engineering Contradiction:
Improvestructural simplicityVSAvoidscreen ratio
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent introduces a movable mounting frame that can extend and retract along the top edge of the housing. This dynamic mechanism allows the camera assembly to be positioned optimally for functionality while enabling the screen area to maximize when the camera is retracted, thus increasing the screen ratio without permanently complicating the structure.

Inventive Principle:
Principle #15Dynamics
