Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card storage devices, such as wallets and purses, are cumbersome and time-consuming to use, with difficulties in inserting and retrieving cards, and there is a risk of cards falling out, necessitating a solution for comfortable, intuitive, and secure card access.
Innovation Solution
A card storage device with an ejector mechanism and gripping elements that space cards relative to each other, allowing easy access and preventing them from falling out, while being made from electromagnetically insulating materials to protect against electronic pickpocketing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cards are stored in a compact arrangement in pockets, then space utilization is improved, but access time and ease of retrieval deteriorate
Solution Approach 1:
The patent transforms the traditional flat pocket storage into a three-dimensional structure with multiple levels and tiers. Cards are arranged in staggered positions at different heights and depths, allowing users to access cards from various angles and levels, thereby reducing retrieval time while maintaining compact overall dimensions.
Solution Approach 2:
The storage device is divided into multiple independent compartments, pockets, and slots that can be accessed separately. Each card or group of cards can be independently retrieved without disturbing other cards, enabling quick access to specific cards while maintaining a compact organized structure.
2Quantity of substance
If multiple cards are stored in pockets, then storage capacity is improved, but the risk of cards falling out increases
Solution Approach 1:
The patent employs elastic retaining bands, flexible clips, and spring-loaded mechanisms that conform to the shape of cards and provide adaptive retention force. These flexible elements securely hold multiple cards in place while allowing for easy insertion and removal, preventing cards from falling out during normal use.
Solution Approach 2:
The retaining mechanisms incorporate dynamic elements such as springs and elastic materials that automatically adjust their retention force based on the number and size of cards inserted. This dynamic adaptation ensures secure holding of varying card quantities without requiring manual adjustment, maintaining reliability across different storage scenarios.
3Ease of manufacture
If traditional wallet structures are used, then manufacturing simplicity is improved, but ease of operation and user comfort deteriorate
Solution Approach 1:
The device is constructed from modular components including separate housing sections, independent card slots, and discrete retaining mechanisms. This modular segmentation simplifies manufacturing by allowing each component to be produced and assembled independently, while also enabling intuitive organization and operation for the user.
Solution Approach 2:
The patent incorporates movable elements such as sliding trays, pop-up card holders, and spring-loaded ejectors that enhance user comfort and ease of operation. These dynamic features allow smooth card insertion and retrieval with minimal effort, making the device more intuitive to use while being manufactured using standard mechanical components.
