Solution Overview

Problem

Existing wireless devices often have limited functionality and are not adaptable to multiple scenarios, as they are either general-purpose devices with many functions but not specific enough or dedicated devices that cannot handle multi-demand and multi-scenario applications.

Innovation Solution

An electronic device comprising a master device and a slave device, where the slave device performs a first function when connected to the master device and a second, different function when separated, allowing for enhanced functionality and flexibility without the need for additional hardware like repeaters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If general-purpose devices integrate many functions, then device functionality is improved, but adaptability to specific scenarios deteriorates

Engineering Contradiction:
Improveadaptability to specific scenariosVSAvoiddevice functionality
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into a master device and a slave device that can be physically separated. The slave device contains a functional component that can operate in different modes depending on whether it is connected to the master device, allowing specific functionality to be segmented and activated only when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The functional component in the slave device dynamically changes its operation mode based on the connection state with the master device. When connected, it performs the first function; when separated, it performs the second function, enabling adaptability to different scenarios without increasing overall device complexity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If dedicated devices are used for specific functions, then adaptability to specific scenarios is improved, but multi-demand and multi-scenario applications deteriorate

Engineering Contradiction:
Improvemulti-demand and multi-scenario applicationsVSAvoiddevice functionality
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slave device's functional component is designed to perform multiple functions based on its connection state. It can function as part of the master device when connected and as an independent device with different functionality when separated, achieving multi-functionality without requiring multiple dedicated devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The functional component automatically determines its own operation mode based on whether it detects a physical connection with the master device. This self-service mechanism eliminates the need for complex external control systems to manage the device's multiple functions.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If additional repeaters are deployed to extend wireless coverage, then wireless signal coverage is improved, but hardware cost and device complexity deteriorate

Engineering Contradiction:
Improvewireless signal coverageVSAvoidhardware cost
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The slave device serves dual purposes: it can extend wireless coverage when separated from the master device while maintaining the ability to function as part of the master device when connected. This eliminates the need for separate repeater hardware, reducing overall system complexity and cost.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wireless coverage extension capability is extracted as a separate function that the slave device can perform independently when detached from the master device, rather than requiring a permanently attached repeater or additional dedicated hardware.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electronic device and an information processing method are provided. The electronic device includes a master device and a slave device. The master device includes a first functional component with a first function. The first function comprises transmitting a first wireless signal and receiving a second wireless signal transmitted by an external electronic device. In response to that the slave device is physically connected to the master device, the slave device performs the first function. In response to that the slave device is separated from the master device, the slave device performs a second function. The second function is different from the first function.
