Card Holder Wallet Push Mechanism for Quick Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional card holder wallets are cumbersome and time-consuming to use, as users must insert their fingers to retrieve cards from accommodating cavities, making it difficult to access and manage multiple cards efficiently.
Innovation Solution
A card holder wallet with a push device that includes a button, push wheel, push rod, and elastic reset member, allowing users to easily push cards out of the cavity through a rotating mechanism, along with a flexible protective sleeve and elastic member for secure card storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional card holder wallet with accommodating cavity and cover is used, then cards can be stored securely, but users must insert fingers into the cavity to retrieve cards, which is time-consuming and labor-intensive
Solution Approach 1:
The patent introduces a push rod as an intermediary tool between the user's finger and the card. The push rod extends through the cavity wall, allowing users to push cards out from a distance without inserting fingers into the cavity. This mediator component solves the problem of difficult card retrieval while maintaining secure storage.
Solution Approach 2:
The push rod mechanism allows cards to be ejected automatically when pushed, eliminating the need for manual finger insertion and extraction. The card holder serves itself by providing a mechanical aid that automates the card retrieval process, reducing labor intensity and time consumption.
2Quantity of substance
If multiple cards are stored in the accommodating cavity, then card management capacity increases, but cards become difficult to distinguish and access
Solution Approach 1:
The patent divides the card storage system into multiple independent accommodating cavities, each potentially dedicated to specific card types. This segmentation allows users to organize cards by category, making it easier to locate and access specific cards without sifting through all cards in a single large cavity.
Solution Approach 2:
The push rod acts as a mediator that enables selective access to individual cards within the cavity. By pushing specific cards out through the push rod, users can quickly identify and retrieve desired cards without manually searching through multiple stacked cards, thus improving card management efficiency.
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
Enables quick and accurate retrieval of desired cards by using the push device to expel them from the wallet, while the elastic member and protective sleeve ensure secure storage and prevent card loss, improving user convenience and efficiency.
Implementation Method 1
one end of the elastic reset member is connected to the button, and the other end of the elastic reset member is connected to the shell; when the button is pressed, the elastic reset member is compressed; and an elastic reset force provided when the elastic reset member is compressed pushes the button to be reset

AI summary
The present disclosure also provides a card holder wallet. The card holder wallet includes a shell and a push device. The shell is provided with a first accommodating cavity and a first accommodating opening. The first accommodating cavity is encircled by a side wall of the shell. The first accommodating opening is communicated with the first accommodating cavity. The first accommodating cavity is configured to accommodate a card. The push device is connected to the shell. The push device is configured to push the card out of the first accommodating cavity via the first accommodating opening. Through the above structure, a user can easily push a card in the first accommodating cavity towards the first accommodating opening and out of the first accommodating cavity through the push device, making it easy for the user to accurately and quickly fetch a desired card.
