Universal Totable Battery Backup with Strap Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in charging mobile devices while on the go due to the bulkiness of backup batteries and the need to access internal bag batteries, which requires opening the bag, disrupting device usage and being costly to integrate a backup battery into fashion accessories like bags.
Innovation Solution
A charging device with a mechanism to attach to a bag's shoulder strap, providing external access to input and output ports, allowing users to charge devices comfortably without opening the bag, using a universal backup battery with various attachment methods such as matable structures, clips, and adhesive elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a backup battery is integrated inside the bag, then users can charge devices without opening the bag, but the bag becomes more expensive and less adaptable to different bag types
Solution Approach 1:
The charging system is divided into two separate components: a universal backup battery unit and an attachment mechanism. The battery can be detached and reattached to different bags, allowing the charging function to be separated from any specific bag structure. This enables the same battery to serve multiple bag types without integrating it permanently into one bag design.
Solution Approach 2:
The backup battery is designed with a universal attachment mechanism that can be configured to attach to various bag types including shoulder straps, handles, and other structural elements. The attachment mechanism includes adaptable components such as straps, clips, and adhesive elements that can accommodate different bag configurations, making the charging solution universally applicable across multiple bag styles.
2Duration of action of moving object
If a backup battery is made bulky to provide sufficient power, then battery capacity increases, but the device becomes difficult to hold and use comfortably
Solution Approach 1:
Instead of carrying a bulky battery in the hand, the battery is redistributed across three dimensions: attached to the bag (freeing hands), positioned on the shoulder strap (utilizing body carriage), or distributed across multiple smaller battery units. This dimensional redistribution allows sufficient battery capacity while maintaining ease of operation, as the battery is carried passively on the body rather than actively held.
3Reliability
If the charging interface is placed inside the bag, then the battery is protected, but users must open the bag to access the interface for charging
Solution Approach 1:
The charging interface is positioned at the boundary between the interior and exterior of the bag, acting as an intermediary location. The interface can be accessed from the outside of the bag through openings, flaps, or designated access points, allowing users to connect charging cables without fully opening the bag. This intermediary positioning maintains battery protection while enabling convenient charging access.
4Ease of operation
If each bag type includes a customized backup battery, then charging is optimized for that specific bag, but the cost of manufacturing increases significantly
Solution Approach 1:
A single universal backup battery design with an adaptable attachment mechanism serves multiple bag types, eliminating the need to manufacture customized batteries for each bag style. The attachment mechanism can be configured through simple assembly variations rather than custom manufacturing, significantly reducing production costs while maintaining charging convenience across different bag types.

AI summary
A totable ensemble is attachable to a plurality of totable objects for re-charging peripheral power sources such as mobile communications devices thereby. The totable power source ensemble includes a primary power bank and a mechanism for attaching the primary power bank to a wide variety of totable objects such as backpacks, purses, and hand luggage. The primary power bank basically includes a battery and a mechanism for accessing power stored by the battery. The mechanism for attaching the primary power bank to a totable object may include an assembly-receiving pocket or other structure that provides matable attachments for attaching the assembly-receiving pocket or other structure to an attachment structure associated with each totable object. The battery is thus made accessible upon the totable object and the attachment mechanism enables the user to attach and re-attach the ensemble to any number of totable objects for ease of device recharge-ability.
