Solution Overview
Problem
Existing wireless communication systems face issues with increased power consumption during handovers from low-power wireless communication units like NFC or BLE to higher-power units like Bluetooth or Wi-Fi, leading to potential battery exhaustion and communication failures.
Innovation Solution
A wireless communication apparatus that includes both a low-power wireless communication unit (e.g., BLE) and a higher-power unit (e.g., Wi-Fi), with a power supply circuit and a state detection unit to determine the optimal handover based on battery state, allowing the system to switch between the two to conserve power and ensure reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handover from low-power wireless communication (NFC/BLE) to higher-power wireless communication (Bluetooth/Wi-Fi) is performed, then communication capability is improved, but electric power consumption increases
Solution Approach 1:
The patent implements dynamic selection of wireless communication modes based on real-time battery state detection. The system transitions from static handover protocols to dynamic adaptation, where the communication mode (NFC, BLE, Bluetooth, or Wi-Fi) is selected according to the detected battery charge level, thereby optimizing power consumption while maintaining communication capability.
Solution Approach 2:
The patent changes the operational parameters of the wireless communication system by introducing battery state as a decision parameter. The control unit modifies communication behavior based on battery charge levels, switching between different communication protocols (NFC for very low battery, BLE for low battery, Bluetooth/Wi-Fi for sufficient battery) to balance communication needs with power conservation.
2Productivity
If handover from low-power wireless communication to higher-power wireless communication is performed, then communication speed or data transfer capability is improved, but battery exhaustion risk increases
Solution Approach 1:
The patent applies preliminary action by detecting the battery state before initiating communication and pre-selecting the appropriate communication mode. Instead of allowing communication to start and then risking battery exhaustion, the system evaluates battery charge levels in advance and chooses the most suitable communication protocol (NFC, BLE, Bluetooth, or Wi-Fi) before data transfer begins, preventing battery exhaustion scenarios.
Solution Approach 2:
The patent implements feedback mechanisms where the battery state detection unit continuously monitors charge levels and provides information to the control unit. This feedback loop enables the system to adjust communication mode selection based on current battery status, creating a closed-loop control system that adapts to changing power conditions and prevents battery exhaustion.
3Productivity
If higher-power wireless communication unit is used, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by assigning different communication modes to different battery state conditions. Instead of using a uniform high-performance communication mode regardless of battery status, the system tailors the communication approach to the specific battery condition, using high-power modes (Bluetooth/Wi-Fi) only when battery charge is sufficient and low-power modes (NFC/BLE) when battery charge is low.

AI summary
A wireless communication apparatus includes a first wireless communication unit that performs a first wireless communication, a second wireless communication unit that performs a second wireless communication that consumes less electric power than the first wireless communication, a power supply circuit that supplies electric power to the first and second wireless communication unit by receiving electric power supply from a battery or an external power supply, a state detection unit that detects whether the power supply circuit is in a first state for receiving the electric power supply from the external power supply or in a second state for receiving the electric power supply from the battery, and a first control unit. The first control unit determines which one of the first and second wireless communications to adopt as a wireless communication that is to be used for communication, based on detection result by the state detection unit.
