Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power consumption of Wi-Fi modules in mobile terminals significantly affects battery life, especially due to frequent heartbeat packet transmissions from numerous applications.
Innovation Solution
Implementing a method where the Wi-Fi module enters a sleep state when no data is transmitted for a certain period, and using the Bluetooth module to send heartbeat packets or establish connections, thereby reducing overall power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Wi-Fi module is used for network access and packet transmission, then network communication functionality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic switching between Wi-Fi and Bluetooth modules based on real-time communication needs. The system monitors packet transmission requirements and actively switches between communication modes, making the system adaptable rather than static. This resolves the contradiction by allowing the Wi-Fi module to be active only when necessary for high-speed data transfer, while using low-power Bluetooth for routine communications.
Solution Approach 2:
The patent changes the operational parameters of the communication system by introducing a dual-mode operation where the same communication function can be performed by different modules depending on conditions. The system modifies its behavior by changing which module (Wi-Fi or Bluetooth) is active based on packet transmission requirements, effectively changing the operational parameters to optimize power consumption while maintaining functionality.
2Reliability
If the Wi-Fi module remains active for frequent packet transmissions, then communication reliability is improved, but battery life deteriorates
Solution Approach 1:
The patent introduces Bluetooth as an intermediary communication module that handles specific packet transmission tasks (particularly heartbeat packets and small data transmissions). This intermediary approach allows the system to maintain communication reliability through Bluetooth for routine tasks while reserving Wi-Fi for when it's truly needed, thereby preserving battery life without sacrificing communication reliability.
Solution Approach 2:
The patent segments the communication functionality by dividing packet transmission tasks between two different modules based on their characteristics. Bluetooth handles low-power routine communications (heartbeat packets, small data), while Wi-Fi handles high-speed bulk data transfer. This segmentation resolves the contradiction by ensuring each module is used for tasks it's best suited for, optimizing both reliability and battery life.
3Use of energy by moving object
If Bluetooth module is used instead of Wi-Fi for heartbeat packets, then power consumption is reduced, but communication speed may be affected
Solution Approach 1:
The patent applies local quality by matching the communication task requirements with the appropriate module capabilities. Bluetooth is used locally for specific task types (heartbeat packets, small frequent transmissions) where its lower power consumption is the priority, while Wi-Fi is reserved for tasks requiring high speed (bulk data transfer). This localized application of different communication methods resolves the contradiction by ensuring speed requirements are met for tasks that need it while saving power for tasks that don't require high speed.

AI summary
A method for reducing power consumption of a mobile terminal and a mobile terminal are provided. The method includes: A mobile terminal establishes a Wi-Fi connection to an electronic device by using a Wi-Fi module; the mobile terminal interacts with a server by using the Wi-Fi connection; if the mobile terminal doesn't send or receive a packet within a first time period, the mobile terminal controls the Wi-Fi module to enter a sleep state; and after the Wi-Fi module enters the sleep state, if the mobile terminal needs to send a heartbeat packet, the mobile terminal may establish a Bluetooth connection to the electronic device by using a Bluetooth module, and send the heartbeat packet by using the Bluetooth connection.
