Card Ejector Wallet Structure for Compact Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wallets often face issues of being either too bulky or too small, failing to comfortably fit in pockets and inadequately holding necessary items, while also lacking innovative features for card management and security.
Innovation Solution
A wallet design featuring a shell with a card area, protruding portions, and an ejector mechanism that allows cards to be retained or partially ejected, along with RFID-blocking capabilities and a clip for secure retention, enhancing functionality and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wallet is made compact to fit comfortably in pockets, then the wallet size is reduced, but the capacity to hold necessary items is compromised
Solution Approach 1:
The wallet employs a rail system that segments the card holding space into multiple positions along the length of the wallet. Cards are held in individual slots created by the rails, allowing efficient use of available space while maintaining a compact overall form factor. This segmentation enables the wallet to hold multiple cards without increasing bulk.
Solution Approach 2:
The ejector mechanism introduces a temporal dimension to card access, allowing cards to be quickly ejected in a fanned configuration from the compact wallet body. This dimensional approach to card management enables easy access to individual cards without requiring the wallet to be opened or expanded, maintaining compact storage while improving accessibility.
2Ease of operation
If traditional card retention methods are used, then the wallet structure is simple, but card access requires opening the entire wallet
Solution Approach 1:
The ejector mechanism extracts individual cards from the wallet body through a dedicated ejection path, allowing card access independent of the wallet opening. This extraction mechanism enables users to retrieve specific cards without opening the wallet, significantly improving card access convenience.
Solution Approach 2:
The ejector mechanism provides dynamic control over card ejection, allowing users to selectively eject individual cards at different positions along the rail system. This dynamic capability enables flexible card access patterns, where cards can be retrieved in a fanned configuration without requiring wallet opening, enhancing operational ease.
3Ease of operation
If cards are easily accessible, then card retrieval is quick, but security against unauthorized access is reduced
Solution Approach 1:
The ejector mechanism acts as an intermediary between the user and the cards, providing a controlled interface for card retrieval. This intermediary mechanism allows authorized users to quickly eject cards through a simple interaction while maintaining security, as the ejection path is integrated into the wallet structure and cannot be accessed unauthorizedly.
4Reliability
If the wallet includes RFID-blocking capabilities, then security is improved, but the wallet structure becomes more complex
Solution Approach 1:
The RFID-blocking capability is merged with the existing rail system structure, where the rails themselves or integrated components provide the RFID-blocking function. This merging approach allows the wallet to achieve enhanced security without adding separate, complex RFID-blocking layers, as the same structural elements serve dual purposes: card retention and security.

AI summary
A wallet includes a shell with a front portion, a back portion, and at least one side portion, and defining a card area configured to securably receive at least one card therewithin. The wallet may include at least one protruding assembly coupled to the shell and configured to retain the at least one card within the card area. The wallet may include an ejector mechanism coupled to the shell and configured to move between a first position and a second position. The ejector mechanism may be configured to at least partially eject the at least one card from the card area by moving from the first position to the second position.
