Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face challenges in maximizing battery life due to variable power consumption from wireless data exchanges with application servers, where high energy drain occurs unpredictably, especially in varying network conditions, leading to unexpected short battery life and a tradeoff between application performance and battery conservation.
Innovation Solution
A system and method that dynamically control the synchronization interval between mobile computing devices and application servers based on energy expenditure measurements, adjusting the interval to conserve energy by continuing communication when energy is low and postponing it when energy is high, using an energy detector and power saving module to manage energy consumption effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the synchronization interval is shortened to improve application performance, then data exchange frequency increases, but battery life decreases
Solution Approach 1:
The patent applies dynamics by making the synchronization interval adjustable rather than fixed. The system dynamically changes the interval based on real-time energy expenditure measurements, allowing it to adapt between short intervals for high performance and long intervals for battery conservation, thus resolving the contradiction between productivity and duration.
Solution Approach 2:
The patent changes the parameter of synchronization interval based on energy expenditure conditions. When energy expenditure is low, the system uses shorter intervals to maximize performance; when energy expenditure is high, it extends the interval to preserve battery life, effectively managing the tradeoff between these two parameters.
2Duration of action of moving object
If the synchronization interval is lengthened to conserve energy, then battery life improves, but application performance deteriorates
Solution Approach 1:
The system dynamically adjusts the synchronization interval based on measured energy expenditure. When energy is abundant, it can afford longer intervals; when energy is constrained, it switches to shorter intervals to maintain performance, thus resolving the contradiction in favor of battery life without permanently sacrificing application performance.
Solution Approach 2:
The patent modifies the synchronization interval parameter according to energy expenditure conditions. By extending the interval when energy is low and shortening it when energy is available, the system optimizes battery life while maintaining acceptable application performance levels.
3Productivity
If data synchronization occurs frequently to maintain real-time performance, then application responsiveness improves, but energy consumption increases
Solution Approach 1:
The patent implements feedback by continuously measuring energy expenditure and using this information to adjust the synchronization interval. This closed-loop control allows the system to reduce frequency when energy is high and increase it when energy is low, optimizing the balance between responsiveness and energy consumption.
Solution Approach 2:
The system dynamically adjusts data synchronization frequency based on real-time energy conditions. Rather than maintaining a fixed high-frequency sync for maximum responsiveness, it adapts the frequency downward when energy consumption is high, thus resolving the contradiction between responsiveness and energy use.
4Adaptability or versatility
If the device uses available wireless networks for data exchange, then application functionality improves, but power drain increases due to variable network conditions
Solution Approach 1:
The patent changes the synchronization interval parameter in response to network conditions and energy expenditure. When network conditions cause high power drain, the system extends the interval to reduce energy consumption while maintaining application functionality, thus resolving the contradiction between adaptability and power drain.
Solution Approach 2:
The system uses feedback from energy expenditure measurements to adjust data exchange frequency. This allows the device to maintain application functionality through periodic synchronization while reducing power drain by avoiding unnecessary frequent exchanges, optimizing the balance between functionality and energy use.
