Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices, such as smartphones, integrated with vehicle telematics systems face battery depletion issues due to inefficient use of communication protocols, leading to reduced battery life and operational time.
Innovation Solution
A method is implemented where the vehicle telematics unit monitors the battery charge level of the wireless device and adjusts the communication protocol used over a secondary wireless channel based on the battery status, switching to more power-efficient protocols when necessary, thereby conserving energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device uses high-performance communication protocols to maintain communication quality, then communication reliability is improved, but battery consumption increases
Solution Approach 1:
The system dynamically switches between different communication protocols (Wi-Fi, Bluetooth, cellular) based on real-time battery charge levels. When battery level is high, higher-performance protocols are used; when battery level is low, more power-efficient protocols are activated. This dynamic adaptation resolves the contradiction by making communication reliability adjustable according to energy availability.
Solution Approach 2:
The invention changes the operational parameters of the wireless device by modifying the active communication protocol based on battery state. The system monitors battery charge level and transitions between protocol states (e.g., from Wi-Fi to Bluetooth Low Energy), thereby changing the energy consumption characteristics while maintaining communication functionality.
2Adaptability or versatility
If the wireless device maintains continuous communication capabilities, then operational versatility is improved, but battery life is reduced
Solution Approach 1:
The wireless device is equipped with multiple communication protocols (Wi-Fi, Bluetooth, cellular) that can serve different communication needs. The system selectively activates appropriate protocols based on battery level and communication requirements, providing universal communication capability across different scenarios while optimizing battery life by not maintaining all protocols simultaneously active.
Solution Approach 2:
The invention extracts or deactivates certain communication protocols when battery level is low, removing them from active operation. Instead of maintaining all communication capabilities continuously, the system selectively enables only the necessary protocols based on current battery status, thereby extending battery life while preserving essential communication functionality.
3Speed
If the wireless device uses power-intensive communication protocols, then data transmission speed is improved, but energy loss increases
Solution Approach 1:
The system periodically monitors battery charge levels and adjusts communication protocol selection accordingly. When battery level is sufficient, high-speed protocols are activated; when battery level drops below thresholds, the system switches to lower-power protocols. This periodic assessment and adjustment resolves the contradiction by timing high-speed communication only when energy reserves permit.

AI summary
A method of regulating the battery usage of a wireless device includes receiving information indicating the battery charge level of a wireless device over a first wireless communication channel using a short-range wireless communication protocol; choosing a wireless communication protocol for use by the wireless device with a second wireless communication channel based on the received battery charge level information; constructing a message instructing the wireless device to use the chosen wireless communication protocol for communications via the second wireless communication channel; and sending the message from a vehicle telematics unit to the wireless device.
