Integrated Battery Case for Portable Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face reduced battery life due to increased power demands from enhanced features and lack of easily replaceable batteries, necessitating a solution that extends battery life while protecting the devices from physical damage.
Innovation Solution
A case design that integrates a battery within the lower case portion, connected to electronic circuitry, allowing the upper case portion to slide onto the device, providing additional power and protection while maintaining access to device features and enabling synchronization and charging modes through indicator lights and a button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case is designed to protect the portable electronic device from physical damage, then the device protection is improved, but the case cannot provide additional battery life
Solution Approach 1:
The patent combines two separate functions into a single integrated case: physical protection and power extension. The case structure merges the protective enclosure with an integrated battery pack, allowing the same object to simultaneously protect the device from damage and provide additional battery life through the incorporated power source.
Solution Approach 2:
The case is designed to perform multiple functions simultaneously: it acts as a protective cover for the device, an external battery pack for power extension, and a charging dock when connected to a power source. This multi-functional design resolves the contradiction by making the protective case itself the source of additional battery life.
2Duration of action of moving object
If the battery capacity is increased to extend battery life, then the duration of action is improved, but the device size and weight increase
Solution Approach 1:
The battery pack is nested within the case structure itself, with the battery housed in the lower portion of the case and the electronic device placed in the upper portion. This nesting arrangement allows the battery capacity to be increased without adding external bulk, as the battery is integrated into the case's internal volume.
3Adaptability or versatility
If the case structure is made more complex to provide both protection and battery integration, then the functionality is improved, but the manufacturing complexity increases
Solution Approach 1:
The case is divided into two main segments: a lower case portion housing the battery and electronic circuitry, and an upper case portion that protects the device. This segmentation allows each portion to be manufactured separately using standard molding techniques, then assembled together, reducing overall manufacturing complexity while maintaining integrated functionality.
