Solution Overview
Problem
Existing proximity network systems face challenges in efficiently connecting electronic apparatuses within a specific range without consuming excessive power, particularly in identifying and forming groups while minimizing interference from other networks and conserving battery life.
Innovation Solution
The implementation of Bluetooth devices with a community relationship module, identifying module, and distance detecting module, utilizing Bluetooth 4.0 standard LE link components to enable power-efficient communication and connection between devices with shared community relationships within a 3 to 5 meter range, allowing for data transmission and interaction without waking up the operating system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operating system is woken up to search for nearby proximity networks, then the electronic apparatus can identify and connect with other devices, but the power consumption increases significantly
Solution Approach 1:
The patent divides the device identification system into two independent components: a low-power Bluetooth device that continuously scans for proximity networks, and a main operating system that remains in sleep mode. This segmentation allows the scanning function to operate independently without waking the entire system, thereby resolving the contradiction between reliable device identification and power consumption.
2Duration of action of moving object
If the operating system remains in sleep mode to conserve power, then battery life is extended, but the device cannot actively search for or respond to proximity network requests
Solution Approach 1:
The patent introduces a Bluetooth device as an intermediary component that bridges the gap between the sleep mode operating system and the need for active network searching. The Bluetooth device independently handles all proximity network scanning and connection tasks, allowing the main system to remain in low-power state while maintaining full network search capability through the intermediary Bluetooth component.
3Adaptability or versatility
If multiple electronic apparatuses are connected in a proximity network, then communication and data sharing are enabled, but interference from other proximity networks may occur
Solution Approach 1:
The patent applies local quality by implementing community relationship modules within each Bluetooth device that store and verify specific community identification data. This allows devices to selectively recognize and connect only with other devices belonging to the same community, creating localized connection quality within the proximity network while filtering out interference from devices of other communities.
4Reliability
If the Bluetooth device continuously scans for nearby devices, then connection reliability is improved, but the battery power is consumed faster
Solution Approach 1:
The patent implements periodic action by having the Bluetooth device perform scanning operations at specific intervals rather than continuously. The device wakes up at predetermined times to scan for proximity networks, establishes connections when devices are found, and then returns to a low-power state. This periodic scanning approach maintains connection reliability by regularly checking for available devices while significantly reducing overall power consumption compared to continuous scanning.

AI summary
A proximity network system includes a plurality of Bluetooth devices disposed respectively in each one of a plurality of electronic apparatuses. The Bluetooth devices are arranged for enabling the electronic apparatuses to receive and transmit Bluetooth wireless signals with each other. Each Bluetooth device includes a community relationship module, an identifying module and a distance detecting module. The community relationship module stores a community relationship data of each Bluetooth device. The identifying module reads the community relationship data of each Bluetooth device to identify whether each Bluetooth device has the same community relationship. The distance detecting module determines whether each Bluetooth device is in a proximity network. When the Bluetooth devices are identified to have the same community relationship with each other and are in the proximity network, each electronic apparatus is allowed to receive and transmit the Bluetooth wireless signals with another electronic apparatus.
