Solution Overview

Problem

Existing data sharing methods between portable electronic devices are inconvenient and inefficient, requiring manual connection and authentication processes.

Innovation Solution

A method and apparatus that detect the location relationship between devices to determine the share mode and content to be shared, using spatial sensors and image capturing units to establish connections and set access permissions based on the device's position relative to the user interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual connection and authentication measures are used for data sharing, then data security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvedata securityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects device location relationships and determines share modes without requiring manual user intervention. The electronic devices self-identify their spatial relationships and automatically establish appropriate sharing permissions, eliminating the need for manual connection setup and authentication while maintaining security through location-based access control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations (physical cable connections and manual authentication input) with automated electronic detection and processing. Location sensors and processors automatically detect device positions and establish sharing relationships, substituting the mechanical manual process with an electronic automated system that maintains security while improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual connection and authentication processes are used, then access control is improved, but productivity deteriorates

Engineering Contradiction:
Improveaccess controlVSAvoidsharing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary detection of location relationships and pre-determines appropriate share modes before actual data sharing begins. By automatically establishing access permissions based on detected spatial relationships in advance, the system eliminates the need for manual authentication during the sharing process, thereby maintaining access control while significantly improving sharing efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The electronic devices automatically perform access control functions by detecting their own location relationships and self-determining appropriate share modes. This self-service mechanism eliminates the need for manual authentication while maintaining security, allowing data sharing to proceed immediately once devices are in proximity, thus improving productivity without sacrificing access control.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If location-based automatic sharing is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates location detection and data sharing functionality into existing electronic devices that users already possess. By making the location-based sharing system universal across different device types (smartphones, tablets, computers), the patent avoids requiring specialized equipment, thereby improving ease of operation without significantly increasing perceived device complexity for the end user.

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

Solution Approach 2:

The system uses the device's existing location sensors and processors as intermediaries to enable automatic sharing. Rather than adding complex external hardware, the patent leverages the intermediary capabilities already present in modern electronic devices (GPS, accelerometers, processors) to achieve location-based automatic sharing, thus improving ease of operation while minimizing the increase in device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Disclosed are a data sharing method used in a first electronic device connected to a second electronic device. A method involves detecting a location relationship between the first electronic device and the second electronic device, determining a share mode of the first electronic device according to the location relationship and determining, according to the share mode, data content to be shared between the first electronic device and the second electronic device. Data sharing may be implemented between devices by setting different access permissions according to the location relationship between the electronic devices.
