Solution Overview
Problem
Smart devices with multiple wireless communication interfaces face challenges in managing connections and power efficiency, particularly in battery-powered devices, as they are unaware when surrounding devices form connections, leading to increased complexity and energy consumption.
Innovation Solution
A method where a first device in a wireless communication system transmits advertisement packets to a main device, forming a Bluetooth Low Energy (BLE) connection based on these packets, and activates power to provide a specific service, allowing power control of connected devices without separate control signals, using stored parameter settings for efficient service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth devices continuously monitor and maintain connections with multiple surrounding devices, then connection reliability and service availability are improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by storing connection parameters and device information in advance before actual connection is needed. When a device enters the connection range, the pre-stored parameters enable immediate connection establishment without extensive negotiation, thus maintaining reliability while reducing the time and energy required for connection management.
Solution Approach 2:
The patent implements self-service through autonomous connection management where devices automatically establish and maintain connections based on pre-configured parameters. The system independently handles connection establishment, parameter configuration, and service activation without requiring continuous user intervention or complex real-time negotiations, thereby reducing power consumption while maintaining connection reliability.
2Adaptability or versatility
If multiple wireless communication interfaces are kept active for seamless connectivity, then service availability is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by implementing adaptive connection management where wireless interfaces are dynamically activated or deactivated based on real-time service requirements and device proximity. Connection parameters are pre-configured to enable rapid switching between active and inactive states, ensuring service availability when needed while minimizing energy consumption during idle periods.
3Stability of the object's composition
If Bluetooth devices perform comprehensive connection discovery and negotiation procedures, then connection stability is improved, but connection time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing connection parameters, device identifiers, and service configuration information before actual connection is needed. When a device enters the connection range, these pre-configured parameters enable immediate connection establishment without extensive real-time negotiation, thereby reducing connection time while maintaining connection stability through verified parameters.
4Adaptability or versatility
If devices without display or user interface implement full Bluetooth connection management, then functional capability is improved, but operational complexity increases
Solution Approach 1:
The patent implements self-service through autonomous connection management where devices automatically establish and maintain connections based on pre-configured parameters. The system independently handles connection establishment, parameter configuration, and service activation without requiring user intervention through displays or interfaces, thereby maintaining functional capability while reducing operational complexity.
