Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices have a reduced display area due to the presence of functional components like receivers, cameras, and flashes, which occupy non-display regions, thereby compromising user experience and screen occupation ratio.

Innovation Solution

An electronic device design featuring a rotatable functional assembly that can move between inside and outside a receiving cavity defined by the display screen, allowing it to be hidden when not in use and exposed for functionality, thus maximizing screen area and simplifying operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If functional components (receiver, camera, flash) are arranged on the front face, then functionality is provided, but display area is reduced

Engineering Contradiction:

ImprovefunctionalityVSAvoiddisplay area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The functional assembly is extracted from the fixed front face position and made rotatable, allowing it to be moved out of the display area when not in use, while remaining accessible when needed

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The functional assembly is transformed from a static arrangement to a dynamic rotatable structure that can change position between inside and outside the receiving cavity, enabling it to adapt between occupying and not occupying display space

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If functional assembly is always exposed, then functionality is easily accessible, but screen occupation ratio is reduced

Engineering Contradiction:

ImproveaccessibilityVSAvoidscreen occupation ratio

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The functional assembly can dynamically change its position between exposed and retracted states, allowing the screen to occupy maximum area when the assembly is inside the receiving cavity, while maintaining easy accessibility when rotated outward

Inventive Principle:

Principle #15Dynamics

3Area of stationary object

If functional assembly is hidden inside receiving cavity, then screen occupation ratio is maximized, but functionality is less accessible

Engineering Contradiction:

Improvescreen occupation ratioVSAvoidfunctionality accessibility

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The rotatable connection enables the functional assembly to be quickly moved from the hidden state inside the receiving cavity to the exposed state outside, maintaining both maximum screen occupation ratio and easy accessibility on demand

Inventive Principle:

Principle #15Dynamics

AI summary

An electronic device may include a body and a functional assembly. The body may define a receiving cavity. The functional assembly may be rotatably connected to the body, and be configured to rotate in a first direction and a second direction to protrude out of the receiving cavity. The functional assembly provided by the present disclosure may not occupy any space of a front face of the electronic device.
