Solution Overview

Problem

Portable electronic devices often have low-resolution front lenses and lack a supplemental light source, resulting in reduced image quality when taking photos in environments with insufficient lighting.

Innovation Solution

An electronic device with a movable assembly and supplemental light sources that move from a hidden position between the display body and the assembly to a visible position beside the display body, providing adjustable light to improve image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a supplemented light source is configured on the display body, then image quality in low-light environments is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveimage brightnessVSAvoiddevice structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the light source assembly movable rather than fixed. The assembly can be moved between a first position (where the light source supplements lighting for the camera) and a second position (where it does not obstruct the display). This dynamic positioning allows the device to adapt its structure based on operational needs, providing illumination when required while maintaining a clean display area otherwise, thus improving image quality without permanently increasing device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes the another dimension principle by moving the light source assembly along the thickness direction of the display body. The assembly can be positioned at different depths within the device structure, allowing it to emerge from the display body when needed and retract when not needed. This dimensional movement enables the light source to provide illumination without permanently occupying space that would obstruct the display or increase overall device complexity.

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

2Illumination intensity

If a supplemented light source is always visible and exposed, then image quality is improved, but the display area is obstructed and device complexity increases

Engineering Contradiction:
Improvelight supplement capabilityVSAvoiddisplay area
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The light source assembly is designed to be movable between different positions. When illumination is needed, the assembly moves to a first position where the light source is exposed and can supplement lighting. When illumination is not needed, the assembly moves to a second position where it does not obstruct the display area. This dynamic positioning resolves the contradiction by allowing the light source to be visible only when required, maintaining full display area otherwise.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The light source assembly is nested within the display body structure. The assembly can be retracted into the display body when not in use, allowing the display area to remain fully unobstructured. When needed, the assembly emerges from the display body to provide illumination. This nesting approach allows the light source to be housed within the device without permanently reducing the display area.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An electronic device including a display body, a fixed back cover, at least one movable assembly and at least one supplemented light source is provided. The fixed back cover is disposed on the display body. The moveable assembly is disposed on the display body and located beside the fixed back cover. The supplemented light source is disposed on the movable assembly and located between the movable assembly and the display body. When the movable assembly is moved or rotated from an accommodating position to an operation position, the supplemented light source moves along with the movable assembly from being hidden between the display body and the movable assembly to out of the display body so as to locate beside the display body.
