Selective Activity Hibernation for Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with limited resources, such as smartphones, face performance issues and crashes when multiple applications are open concurrently, leading to resource wastage and user inconvenience due to insufficient memory and processing power.
Innovation Solution
Implementing a system that selectively causes less active applications to hibernate, preserving their state and allowing them to be revived when needed, thereby freeing up resources for active applications and optimizing system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple applications are kept open concurrently to allow easy switching between activities, then ease of operation is improved, but system resources are exhausted leading to performance degradation and crashes
Solution Approach 1:
The system dynamically adjusts application states based on usage patterns. Applications transition between active and hibernated states automatically, allowing the system to adapt resource allocation in real-time while maintaining the ability to switch between applications without closing them.
Solution Approach 2:
The system changes the operational parameter of applications from fully active to hibernated state. Hibernated applications preserve their state but suspend resource consumption, enabling multiple applications to coexist without exhausting system resources.
2Ease of operation
If applications remain fully active to maintain responsiveness, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The system dynamically transitions applications between active and hibernated states based on usage. Frequently used applications remain active while less used applications hibernate, optimizing the balance between responsiveness and energy consumption.
Solution Approach 2:
The system changes the energy consumption parameter by transitioning applications to a hibernated state that preserves functionality while dramatically reducing resource usage, including energy consumption.
3Productivity
If applications are closed to free up resources, then system performance is improved, but loss of time occurs due to repeated opening and closing
Solution Approach 1:
The system segments application states into distinct levels: active, hibernated, and closed. This segmentation allows applications to be preserved in an intermediate hibernated state that balances resource usage with quick accessibility, avoiding the need to close and reopen applications.
Solution Approach 2:
The system performs preliminary action by automatically hibernating applications that are not currently in use. This pre-action preserves application state and enables rapid resumption without requiring user intervention to reopen applications.
4Device complexity
If all applications are treated equally in resource management, then device complexity is reduced, but adaptability decreases because it cannot optimize for different usage patterns
Solution Approach 1:
The system provides self-service by automatically monitoring and managing application states based on usage patterns. The automatic hibernation mechanism requires minimal user configuration while adapting to individual usage behaviors, balancing simplicity with adaptability.

AI summary
In an electronic device capable of running multiple software applications concurrently, applications, documents, cards, or other activities can be selected for hibernation so as to free up system resources for other activities that are in active use. A determination is made as to which activities should hibernate, for example based on a determination as to which activities have not been used recently or based on relative resource usage. When an activity is to hibernate, its state is preserved on a storage medium such as a disk, so that the activity can later be revived in the same state and the user can continue with the same task that was being performed before the activity entered hibernation.
