Wireless Communication Device Proximity Detection and Auto-Enable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices, such as smartphones, face challenges in establishing communication with external devices like printers when NFC is disabled to conserve power and improve security, leading to user inconvenience due to the need for manual setting changes and potential confusion in accessing NFC and Wi-Fi settings.
Innovation Solution
Implementing a wireless communication device with multiple communicators (BLE, NFC, and Wi-Fi Direct) that automatically switch to NFC or Wi-Fi Direct when proximity to an external device is detected, enabling communication without requiring users to manually enable or disable settings, thereby enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If NFC communicator is turned off to conserve power and improve security, then power consumption is reduced and security is improved, but communication cannot be established with external devices even when in close proximity
Solution Approach 1:
The system performs preliminary detection using BLE to identify when a wireless communication device is in proximity to the image-data output device. This preliminary action triggers the subsequent enabling of NFC communication only when needed, rather than keeping NFC continuously on or requiring manual user activation.
Solution Approach 2:
The system automatically detects proximity through BLE communication and self-enables NFC communication without requiring manual user intervention. The device serves itself by monitoring proximity conditions and autonomously adjusting its communication state.
2Object-affected harmful factors
If NFC communicator is turned off for security, then security is improved, but data exchange with external devices becomes impossible
Solution Approach 1:
The NFC communicator's operational state is made dynamic rather than static. It transitions from an off state to an on state automatically when proximity is detected via BLE, and can return to off state when proximity is lost. This dynamic adjustment allows the system to adapt its security posture based on real-time conditions.
Solution Approach 2:
The system changes the operational parameter of the NFC communicator from disabled to enabled based on the detected proximity condition. This parameter change is triggered automatically when BLE detection confirms the presence of a wireless communication device within proximity.
3Object-affected harmful factors
If manual enabling of NFC is required for proximity communication, then security control is maintained, but user convenience is reduced due to setting confusion and additional操作步骤
Solution Approach 1:
The system performs automatic proximity detection and communication enabling without requiring manual user intervention. The device monitors BLE signals continuously and autonomously activates NFC when appropriate, eliminating the need for users to navigate settings menus or make manual configuration changes.
Solution Approach 2:
BLE communication serves as an intermediary detection mechanism that bridges the gap between security requirements and user convenience. It enables the system to detect proximity conditions and trigger NFC activation automatically, removing the need for direct manual user action while maintaining security through conditional activation.

AI summary
Provided is technology capable of improving user convenience. A wireless communication device configured to connect wirelessly to an external device, includes: a first wireless communicator configured to communicate by a first proximity communication; a second wireless communicator configured to communicate by a second proximity communication having a shorter communication range than the first proximity communication; and a controller configured to execute a process enabling communication by the second proximity communication when proximity to the external device is detected by the first proximity communication.
