Pivotable Wallet with Segmented Card and Coin Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wallet designs for plastic cards are inefficient in allowing targeted removal of individual cards, often causing them to fall out or be difficult to access due to insecure holders and complex mechanisms.
Innovation Solution
A case with two hard shells connected by a pivotable joint, featuring a card storage compartment with a side-opening design and locking mechanism that allows selective access to compartments, ensuring secure storage and easy retrieval of plastic cards, along with a coin storage compartment for organized handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clip holder is used to secure credit cards, then cards are held securely, but inserting and removing cards causes other items to fall out
Solution Approach 1:
The case is divided into separate compartments: a credit card compartment with a dedicated push-button release mechanism, and a separate coin compartment. This segmentation allows independent access to cards without disturbing coins, and independent access to coins without disturbing cards, resolving the conflict between security and ease of operation.
2Reliability
If individual coins are stored in a pocket, then coins are contained, but selectively removing individual coins becomes troublesome
Solution Approach 1:
The coin compartment features a dynamic design where the entire coin pocket can be opened by pressing a button, transforming from a closed containment state to an open access state. This allows coins to be easily accessed and selectively removed while maintaining secure containment when closed.
3Adaptability or versatility
If a multi-purpose portfolio with multiple compartments is used, then various items are organized, but the structure becomes complex and items can easily fall out after opening
Solution Approach 1:
The portfolio is segmented into distinct functional compartments (credit card compartment and coin compartment) with separate access mechanisms. This segmentation simplifies the overall structure by giving each compartment independent functionality, reducing the complexity of interlocking mechanisms while maintaining multi-purpose storage capability.
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
Facilitates secure, space-saving storage and easy access to both plastic cards and coins, preventing accidental loss and simplifying the process of removing or inserting items, while maintaining structural integrity under usual loads.
Implementation Method 1
The container has two half-shells connected to one another by an elastic rear hinge. The elastic back hinge is formed as a back roll hinge from a one-piece sequence of a large number of individual film joint hinges.

AI summary
The case has two hard shells (1,2), a joint interconnecting the two hard shells and a coin storage compartment for coins on the inner side of the former hard shell. The coin storage compartment has a coin opening for the passage of the coins. The two hard shells are pivotable in a closed position around the joint. The hard shells have inner shells made of plastic and outer shells made of aluminum or leather.
