Solution Overview

Problem

Current mobile terminals, such as smartphones and tablets, face a trade-off between performance and thinness, limiting their usage scenarios due to restricted design constraints.

Innovation Solution

A master device with a rotatable bracket system that allows for the installation and detachment of a slave device, enabling communication between the two even when separated, with the bracket rotating between a recessed and extended position to enhance usability and aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If mobile terminals are made thinner, then portability and aesthetics are improved, but performance and functionality are limited

Engineering Contradiction:
ImprovethicknessVSAvoidusage scenarios
Core Design Contradiction:
Length of stationary objectVSAdaptability or versatility

Solution Approach 1:

The bracket is designed to be rotatable between a first position (received in the receiving groove) and a second position (rotated out of the receiving groove). This dynamic structure allows the device to adapt between a thin profile when the bracket is retracted and an extended configuration when the bracket is rotated out, enabling multiple usage scenarios without permanently increasing device thickness

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is divided into a master device and a detachable slave device. The slave device can be installed on or detached from the master device, allowing the system to be segmented for portability or combined for enhanced functionality. This segmentation resolves the contradiction by enabling performance enhancement through modular addition rather than permanent thickening

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a slave device is installed on the main body, then functionality is enhanced, but the aesthetic appearance is compromised due to the protruding bracket

Engineering Contradiction:
Improvedevice configuration flexibilityVSAvoidaesthetic appearance
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The bracket's rotatable design allows it to be dynamically positioned: when not in use, it is rotated to the first position and received in the receiving groove, maintaining a smooth aesthetic appearance; when the slave device needs to be installed, it is rotated to the second position to provide the necessary support structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bracket is nested within the receiving groove when not in use, creating a sleek appearance. The slave device is then installed on the protruding bracket, effectively nesting the slave device within the overall device structure while maintaining aesthetic appeal

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A master device is capable of communicating with an external device. The master device is capable of installing a slave device and allowing the slave device being detached from the master device. The slave device is capable of communicating with the master device after it is detached from the master device. The master device includes a main body and a bracket connected to the main body. The main body includes a front surface and a rear surface disposed opposite to the front surface. The front surface is provided with a receiving groove. The bracket is located at a side of the front surface. The bracket is capable of being rotated to a first position and a second position relative to the main body. The bracket is received in the receiving groove when in the first position, and is rotated out of the receiving groove when in the second position.
