Smartphone Wallet Keychain Integration Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphones lack a secure structure within internal compartments to safely store items like banknotes, credit cards, ID documents, keys, and other slim items, leading to instability and safety issues when used for their intended functions.
Innovation Solution
An expandable multi-compartment pocket inspired by an accordion's movement is integrated inside the smartphone, allowing items to be stored securely within independent compartments that expand when the phone is open and retract when closed, combined with small flexible hooks with a knurled system to safely hold keys, ensuring items are only accessible when the phone is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If items are stored in empty internal compartments of the smartphone, then the smartphone can hold wallet and keychain items, but the items are free to move and unstable when the smartphone is used
Solution Approach 1:
The internal compartment is segmented into multiple independent pockets with dividers, creating separate storage spaces for different items (cash, cards, ID documents). This segmentation prevents items from moving freely while maintaining organized storage functionality.
Solution Approach 2:
The wallet structure is nested within the smartphone body, with flexible pockets that can expand and contract. The pockets are integrated into the smartphone's internal structure, allowing the wallet function to be contained within the device without external attachments.
2Ease of operation
If the smartphone is opened to access internal compartments, then items can be accessed, but the structure becomes complex requiring opening mechanisms
Solution Approach 1:
The pocket structure is designed to be dynamic and flexible rather than rigid. The pockets can expand when the smartphone is open and retract when closed, automatically adapting to the device's state without requiring separate opening mechanisms for the wallet compartment.
Solution Approach 2:
The smartphone's existing opening mechanism serves dual purposes: it provides access to the display and simultaneously expands the internal wallet compartments. This multi-functionality eliminates the need for separate access mechanisms, reducing overall device complexity.
3Device complexity
If static internal receptacles are used, then the structure is simple, but items cannot be securely held when the phone is closed
Solution Approach 1:
The pockets transition from a static to dynamic design, where the flexible material allows the pockets to expand when needed and securely conform to items when closed. This dynamic behavior provides security without requiring complex locking mechanisms.
Solution Approach 2:
The pocket walls are constructed from flexible material that can adapt to the shape and size of stored items. This flexibility allows the pockets to securely hold items in various positions while maintaining a simple overall structure without rigid frames or complex fasteners.

AI summary
The present invention relates to the innovation of an ordinary openable smartphone, so that while maintaining its electronic functionality, it can also internally integrate the wallet and keychain functions. Thanks to a structure with the wallet function, consisting of a multi compartment pocket able to expand when opening the smartphone and to retreat when closing. And thanks to a further structure, there is the keychain function, consisting of small flexible hooks made with a knurled system that blocks the keys.The wallet and keychain functions will be accessible by pushing an external button that opens the smartphone into two parts, like a book.
