Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods between mobile terminals and access terminals using WiFi or Bluetooth hotspots require manual switching, leading to poor user experience and high power consumption due to unnecessary connection maintenance during idle data communication.
Innovation Solution
A method and terminal configuration that automatically switch between WiFi and Bluetooth data transmission links based on detected data transmission rates, using a processor to determine if the rate meets preset thresholds and instructing the transceivers to switch communication links, thereby enabling seamless data transfer and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WiFi is used for data transmission, then transmission rate is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between WiFi and Bluetooth communication modes based on real-time data transmission rate requirements. When high transmission rate is needed, WiFi is activated; when low rate suffices, Bluetooth is used to conserve power. This dynamic adaptation resolves the contradiction by matching communication mode to actual needs rather than using a fixed mode.
Solution Approach 2:
The system changes the communication parameter (transmission mode) from static to variable, allowing switching between WiFi and Bluetooth based on detected transmission rate conditions. This parameter change enables the system to optimize both speed and power consumption by selecting the appropriate communication technology for each operational context.
2Reliability
If WiFi connection is maintained during idle data communication, then connection availability is improved, but power consumption increases
Solution Approach 1:
Instead of maintaining continuous WiFi connection, the system periodically checks data transmission rate requirements and switches to Bluetooth when high-rate transmission is not needed. This periodic evaluation and switching mechanism maintains connection availability when needed while conserving power during idle periods.
Solution Approach 2:
The system extracts the essential function of data transmission from the WiFi protocol and implements it alternatively through Bluetooth when high transmission rates are not required. This separation allows the system to maintain connection availability through Bluetooth for basic communication while avoiding WiFi's high power consumption during idle states.
3Adaptability or versatility
If manual switching between Bluetooth hotspot and WiFi hotspot is required, then device compatibility is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs automatic mode selection and switching between WiFi and Bluetooth based on detected transmission rate requirements, eliminating the need for manual user intervention. The device serves itself by autonomously determining the optimal communication mode and executing the switch, thereby improving ease of operation while maintaining adaptability to different transmission scenarios.
Solution Approach 2:
The system continuously monitors data transmission rate conditions and uses this feedback to automatically adjust the communication mode. This closed-loop control mechanism ensures the system adapts to changing requirements without user input, resolving the contradiction between compatibility and ease of operation by making the switching process transparent and automatic.
4Ease of operation
If automatic mode switching is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system merges the mode selection and switching functionality into the existing communication management architecture, integrating rate detection, mode evaluation, and switching execution into a unified automatic control mechanism. This integration approach minimizes additional complexity while achieving automatic switching capability.
Solution Approach 2:
The system implements self-service through automatic mode selection based on detected transmission rate conditions, eliminating manual switching operations. The device autonomously monitors conditions and executes appropriate mode changes, improving ease of operation while managing complexity through automated decision-making algorithms.
