Solution Overview

Problem

Traditional wallets make it difficult to quickly locate and use a specific card, leading to inefficiency and increased risk of misplacement or damage, while also exposing cards to theft and skimming.

Innovation Solution

A rotating card wallet device with RFID-blocking materials, featuring a top and bottom member connected by support and pivot posts, allowing cards to be rotated outward for use without full removal, and equipped with an elastic strap for currency and GPS tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cards are stored in close proximity in a traditional wallet, then the wallet size is reduced, but it becomes difficult to quickly locate and use a specific card

Engineering Contradiction:

Improvecard retrieval speedVSAvoidcard location difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The wallet divides card storage into multiple compartments or sections, allowing cards to be organized by category, frequency of use, or type. This segmentation enables users to quickly locate specific cards without searching through all cards, thereby improving retrieval speed while maintaining a compact wallet size

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a rotational mechanism that adds a dimensional aspect to card access. Cards can be rotated into different positions or orientations, creating a new dimension for organizing and accessing cards. This allows rapid card retrieval by rotating the wallet or card holder to bring the desired card to an accessible position, solving the contradiction between compact storage and quick access

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If cards are frequently removed and reinserted into the wallet, then card usage is enabled, but the likelihood of misplacement or damage increases

Engineering Contradiction:

Improvecard usage convenienceVSAvoidcard security and integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts or removes the need to fully remove cards from the wallet for usage. Instead, cards can be accessed, swiped, or tapped while remaining in their protective holders within the wallet. This extraction of the removal step maintains card security and prevents damage while still enabling convenient usage

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wallet design implements a nested structure where card holders are contained within the wallet body. Cards remain nested within their protective holders, which are themselves nested within the wallet. This nested arrangement allows cards to be used without being fully extracted, maintaining both convenience and security by keeping cards protected yet accessible

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of manufacture

If traditional wallet materials are used, then manufacturing cost is reduced, but cards are exposed to theft and skimming

Engineering Contradiction:

Improvemanufacturing costVSAvoidcard theft and skimming risk

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent employs composite materials that combine traditional wallet materials with RFID-blocking or electromagnetic shielding layers. This composite construction maintains the aesthetic and tactile properties of traditional materials while adding a protective layer that blocks unauthorized scanning. The composite material approach balances manufacturing feasibility with enhanced security against theft and skimming

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent converts the potential harm of electromagnetic signals (used for unauthorized skimming) into a benefit by implementing RFID-blocking materials. These materials actively counteract electromagnetic interference, transforming the threat of electronic theft into a protective feature. The same electromagnetic properties that enable contactless payment also enable the blocking mechanism to protect against unauthorized scanning

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A rotating card wallet device is provided. The device is comprised of a wallet body, which includes a top member and a bottom member, both preferably made from RFID-blocking materials. The members are connected to each other via support posts and pivot posts, allowing for the rotation of a card-holding member secured around a pivot post and between the members. The card-holding member, which secures a card by its corner once the card is placed into the member, can be rotated outward for card usage without complete removal of the card from the device. Additionally, the body may include an elastic strap for holding paper currency and housing a GPS device.
