ResQ Battery Backup for Cellphones Using Segmented Reserve Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellphone batteries often run out of power at inconvenient times, forcing users to limit device usage or render the device unusable, due to insufficient energy storage capacity.
Innovation Solution
An energy-storage apparatus with a non-rechargeable battery and cellphone interface, designed to provide a backup power supply, typically configured to be used for emergency or important events, featuring a sealed packaging that isolates the battery until needed, ensuring a shelf-life of over a year and discouraging trivial use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a rechargeable battery is used in the cellphone, then the device can be recharged and used multiple times, but the battery cannot maintain readiness for extended periods without degradation
Solution Approach 1:
The invention separates the battery system into two distinct components: a rechargeable battery for routine charging and a reserve battery sealed in packaging for long-term readiness. This segmentation allows each battery type to optimize its function - the rechargeable battery handles frequent charging cycles while the sealed reserve battery maintains stability for extended periods.
Solution Approach 2:
The reserve battery is pre-sealed in packaging that isolates it from environmental factors before use. This preliminary sealing action preserves the battery's chemical stability and readiness for extended periods (greater than 1 year shelf-life) without requiring charging cycles, ensuring reliability when needed.
2Duration of action of moving object
If the battery capacity is increased to provide longer usage, then the device can operate for extended periods, but the device size and weight increase
Solution Approach 1:
The total energy capacity is divided between a smaller rechargeable battery for routine use and a compact reserve battery sealed in packaging. This segmentation provides extended total usage duration without requiring a single large battery that would significantly increase device volume.
Solution Approach 2:
The invention uses a non-rechargeable reserve battery in sealed packaging that is discarded after use. This approach provides additional energy capacity without the complexity and size of a large rechargeable battery, as the reserve unit is compact and intended for single use.
3Reliability
If the battery is kept in a ready-to-use state for extended periods, then it can provide immediate backup power, but the battery may degrade or lose charge
Solution Approach 1:
The reserve battery is pre-sealed in packaging that isolates it from environmental factors (air, moisture) before use. This preliminary sealing action preserves the battery's chemical stability and extends shelf-life to greater than 1 year while maintaining readiness for immediate use when activated.
Solution Approach 2:
The sealed packaging creates an inert environment that protects the reserve battery from oxidation and other environmental degradation. This inert protection maintains battery reliability and extends shelf-life without requiring the battery to be charged or activated during storage.
4Reliability
If the apparatus is designed for single use with sealed packaging, then the battery remains stable for long periods, but the user cannot recharge or reuse it
Solution Approach 1:
The power system is segmented into a rechargeable battery component and a sealed non-rechargeable reserve battery component. This segmentation allows the rechargeable portion to be reused and recharged, while the sealed reserve portion maintains long-term stability and is discarded after single use.
Solution Approach 2:
The invention incorporates a disposable reserve battery in sealed packaging that provides additional energy capacity. This disposable component complements the rechargeable battery, offering long-term stability without requiring rechargeability, and is discarded after single use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
a battery, coupled to the housing; and a cellphone interface coupled to the housing, configured to be inserted into an opening of the cellphone, to electrically couple the battery to the power supply of the cellphone, and to carry current from the battery to the power supply
Implementation Method 2
the apparatus further includes a sealed packaging in which the energy-storage apparatus is disposed. the packaging is configured to be generally not resealable following opening of the packaging. the packaging includes a metal foil. the packaging is generally impermeable to air.
Data Source
AI summary
An energy-storage apparatus for providing emergency backup power to an electronic device has a housing, a battery integrated within the housing, and an interface configured to be inserted into a data port of the electronic device to electrically couple the battery to the power supply of the electronic device. The interface is rigidly coupled to a top surface of said housing and is centered at about a midpoint of its length. The height and depth of the housing are shorter than the length. The housing has a front surface with an open dimple centered at about a midpoint of its length.
