A wallet-sized carrying case with hingedly connected panels featuring electromagnetic shielding members and a releasable locking mechanism to prevent accidental opening, combined with durable materials to maintain shielding effectiveness and protect contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wallet-sized carrying case with hingedly connected panels and electromagnetic shielding members is used, then multiple contactless smartcards are shielded from unauthorized scanning, but the case structure becomes more complex
Solution Approach 1:
The carrying case is divided into multiple hingedly connected panels (front panel, middle panel, rear panel), each containing electromagnetic shielding members. This segmentation allows the shielding function to be distributed across separate components while maintaining overall case functionality and enabling independent assembly of each panel.
Solution Approach 2:
The patent embeds electromagnetic shielding members within the panel structures themselves, nesting the shielding function inside the case components. The shielding members are integrated into the front, middle, and rear panels, creating a nested configuration where the protective function is contained within the structural elements.
2Reliability
If a releasable locking mechanism is added to prevent accidental opening, then card security is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be automatically engaged when the front panel is closed, utilizing the natural closing motion of the hinged panels to trigger the lock. This self-service approach eliminates the need for manual locking operations while maintaining secure card storage, reducing operational complexity despite the added mechanical component.
3Reliability
If durable materials are used to maintain shielding effectiveness, then shielding reliability is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The carrying case panels are constructed using composite materials that integrate electromagnetic shielding properties into the structural components. The shielding members are incorporated within the panel assemblies, creating composite structures that provide both mechanical durability and electromagnetic protection in single manufactured units, simplifying the overall manufacturing process.
4Adaptability or versatility
If the case is designed to hold multiple cards and personal items, then versatility is improved, but the case size and complexity increase
Solution Approach 1:
The carrying case is designed with multiple card pockets and storage compartments within its panels, enabling it to hold various types of cards (contactless smartcards, magnetic stripe cards, identification cards) and personal items simultaneously. The hinged panel structure with integrated shielding members provides universal protection for diverse card types without requiring separate protective devices for each card category.

Function Achieved in This Case
The solution effectively shields multiple contactless smartcards from unauthorized scanning, prevents accidental opening, and maintains durability, ensuring secure storage of both smartcards and additional personal items like paper currency and receipts.
Implementation Method 1
The RFID reader provides power to the embedded microchip via a modulated magnetic field... the smartcards can be powered up and accessed without the card owner's knowledge... an electromagnetic-shielding enclosure
Implementation Method 2
The RFID reader provides power to the embedded microchip via a modulated magnetic field, allowing the information to be obtained from the card

AI summary
An electromagnetic shielding carrying case comprising a front panel hingedly connected to a middle and rear panel. The front and middle panels each comprise an electromagnetic shielding member with a card holding means affixed to each. The carrying case has a closed position wherein upstanding walls of the front and rear panels are brought into engagement with one another so as to form an enclosure around the middle panel, thus shielding contactless smartcards contained within from being scanned by an RFID reader. A releasable locking means holds the front panel closed against the rear panel, and can be unlocked so the front panel pivots open, creating a first open position wherein contactless smartcards can be accessed in both card holding means. The middle panel can also be pivoted open to reveal a receptacle within the rear shell that holds paper currency or one additional card.
