Electronic Device Secondary Power Source for Emergency Task Completion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices face inconvenience and potential danger when the internal battery discharges, as they may be unable to complete important tasks due to lack of power, especially in situations where charging is not possible.
Innovation Solution
The implementation of a secondary power source, such as an internal coil for electromagnetic induction, allows stored tasks to be completed by activating a backup power source, even when the internal battery is discharged, enabling tasks to be executed by moving the device through a magnetic field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secondary power source is added to enable task completion when battery is discharged, then task completion capability is improved, but device complexity increases
Solution Approach 1:
The patent embeds a secondary power source (coil) within the electronic device's existing structure, nesting the emergency power generation capability inside the device housing without requiring external accessories. This allows the device to generate power through electromagnetic induction when moved through magnetic fields, providing task completion capability while maintaining a compact form factor.
Solution Approach 2:
The secondary power source enables the device to generate its own emergency power internally through electromagnetic induction when moved through a magnetic field, without requiring external charging equipment or infrastructure. This self-service capability allows the device to complete stored tasks independently when the primary battery is discharged.
2Adaptability or versatility
If tasks are stored in memory for later execution, then task completion flexibility is improved, but loss of time for task execution increases
Solution Approach 1:
The patent stores tasks in memory during normal operation when the device has sufficient power, preparing them for later execution. This preliminary action allows tasks to be queued and executed later when power is available through the secondary power source, providing flexibility in task completion timing while minimizing delays through efficient memory management.
3Use of energy by moving object
If a secondary power source is implemented, then energy availability is improved, but manufacturing complexity increases
Solution Approach 1:
The secondary power source coil serves multiple functions: it can generate emergency power through electromagnetic induction, and potentially serve as part of the device's structural or aesthetic design. This multi-functionality justifies the additional manufacturing complexity by providing energy availability across different operational scenarios.

AI summary
An electronic device (200) has an internal battery (209) and a secondary power source (210). When a charge level of the internal battery is above a threshold charge level a plurality of tasks are executed on a processor (210a) of the electronic device, and data concerning at least one of the tasks is stored to a memory (207b) internal to the electronic device. When the charge level of the internal battery is below the threshold charge level, the data concerning the at least one task are retrieved from the memory in response to receiving electrical power from the secondary power source, and the at least one task is executed.
