Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in power management due to their limited power sources and resource consumption from components like GPS receivers and high-power applications, which can lead to rapid battery depletion during continuous operation.
Innovation Solution
A condition-based activation, shutdown, and management system for mobile device applications, utilizing monitoring modules that collect data such as Cell ID, connectivity, GPS, and accelerometer information to determine the device's motion and power levels, switching applications between operational, standby, and shut-down modes to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the GPS receiver and applications operate continuously to provide location-based services, then service availability and responsiveness are improved, but power consumption increases rapidly depleting the battery
Solution Approach 1:
The system dynamically adjusts the operational state of the GPS receiver and applications based on real-time motion detection. When the device is detected as stationary, the system transitions to power-saving mode by shutting down or putting to sleep the GPS receiver and non-critical applications. When motion is detected, the system automatically activates these components to restore full service availability, thus resolving the contradiction between continuous service and power conservation.
Solution Approach 2:
The system changes the operational parameters of power-consuming components based on motion status. By monitoring motion parameters (acceleration, position changes) and switching between distinct operational states (active, standby, shut-down), the system optimizes the balance between service availability and energy consumption according to actual usage conditions.
2Use of energy by moving object
If the device monitors motion continuously using sensors to manage power, then power optimization is improved, but device complexity increases
Solution Approach 1:
The monitoring module performs multiple functions using a unified approach: it collects data from various sensors (accelerometer, GPS, cellular tower triangulation), determines motion status, and controls power states of multiple applications and hardware components. This multi-functional design consolidates complexity into a single management system rather than requiring separate independent control mechanisms for each function.
Solution Approach 2:
The system uses the device's own sensor data and processing capabilities to automatically determine motion status and control its own power consumption without external intervention. The monitoring module leverages existing hardware resources (sensors, processor) to create a self-regulating power management system that reduces the need for additional complex external monitoring equipment.

AI summary
Device, system, and method of condition-based activation, shut-down and management of applications of mobile devices. For example, a method includes: based on one or more collected information items, determining whether or not a condition related to a mobile device is true; and based on the determination, controlling a monitored application of the mobile device by performing at least one of: activating the monitored application; shutting down the monitored application; activating a feature of the monitored application; deactivating a feature of the monitored application; and switching the monitored application from a first mode of operation to a second, different, mode of operation.
