Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-operated mobile wireless information devices face challenges in minimizing power consumption while maintaining high data transfer capabilities, especially due to the increased demand on mobile networks and the need to optimize energy efficiency without increasing production costs.
Innovation Solution
A method and device that automatically modify wireless transfer behavior by activating and prioritizing tasks based on received signal strength indicator (RSSI) values, grouping tasks into time-critical and less time-critical subgroups, and defining a wireless transfer scheme to restrict data transfer during low RSSI periods, thereby reducing power consumption by primarily loading the communication channel with time-critical tasks during low signal quality and less time-critical tasks during high signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transfer is continuously performed to maintain high data transfer capabilities, then data transfer capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic wireless transfer behavior modification by continuously monitoring RSSI values and adjusting data transfer activities accordingly. The system transitions between different operational states (active transfer vs. suspended transfer) based on real-time network conditions, optimizing the balance between data transfer capability and power consumption.
Solution Approach 2:
The patent changes the operational parameters of wireless data transfer based on RSSI threshold values. When RSSI exceeds a predefined threshold, the system allows data transfer; when RSSI falls below the threshold, the system suspends transfer. This parameter-based control mechanism resolves the contradiction by adapting transfer behavior to current network quality conditions.
2Productivity
If all wireless transfer tasks are executed regardless of network conditions, then task completion is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent segments wireless transfer tasks into different priority categories (time-critical tasks vs. non-time-critical tasks). Time-critical tasks are executed regardless of RSSI conditions, while non-time-critical tasks are suspended when RSSI is below the threshold. This segmentation allows the system to maintain essential functionality while improving energy efficiency.
Solution Approach 2:
The patent applies partial action by selectively executing only those tasks that meet both the priority criteria and network condition requirements. Instead of executing all tasks unconditionally, the system performs partial transfers based on current RSSI levels, achieving sufficient task completion while reducing energy waste on non-urgent operations.
3Loss of energy
If the device monitors and adjusts wireless transfer behavior based on RSSI, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the device continuously monitors RSSI values and uses this information to control wireless transfer behavior. The monitored RSSI feeds back to the transfer control logic, creating a closed-loop system that automatically adjusts data transfer based on network conditions, thereby improving energy efficiency through intelligent control.
Solution Approach 2:
The patent enables the device to self-regulate its wireless transfer behavior without external intervention. By autonomously monitoring RSSI and making decisions about task execution based on predefined thresholds and priorities, the device serves itself in optimizing energy efficiency, reducing the need for complex external power management infrastructure.
