Card Holder Structure for Compact High-Capacity Card Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wallets and card holders are limited in the number of cards they can accommodate, often requiring increased size to store more cards, which makes them inconvenient to carry and difficult to use.
Innovation Solution
A card holder design featuring a case with a first cavity and a card arm that pushes cards out in a dispersed state, combined with a cover member that forms a variable-volume second cavity, allowing for increased card storage without significantly increasing the holder's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of pockets is increased to accommodate more cards, then the card storage capacity is improved, but the wallet size increases making it inconvenient to carry
Solution Approach 1:
The card holder is divided into multiple functional regions: a first cavity for storing card stacks and a second cavity for individual cards, with a partition wall separating them. This segmentation allows different card storage methods to coexist, maximizing storage capacity within a compact overall structure.
Solution Approach 2:
The card arm extends from the first cavity toward the second cavity, creating a three-dimensional storage arrangement. This dimensional extension allows cards to be pushed out in a dispersed state without increasing the overall footprint of the card holder.
2Reliability
If the card and pocket are designed to fit tightly to prevent cards from falling out, then the card retention is improved, but the ease of taking out the card deteriorates
Solution Approach 1:
The card arm is pre-positioned within the first cavity and is configured to automatically push cards out in a dispersed state when the card holder is opened or accessed. This preliminary action of card ejection eliminates the need for users to manually extract tightly fitted cards, resolving the contradiction between secure retention and ease of access.
3Quantity of substance
If the size of the card holder is increased to accommodate more cards, then the card storage capacity is improved, but the portability deteriorates
Solution Approach 1:
The second cavity is nested within or adjacent to the first cavity structure, utilizing the existing spatial framework. The partition wall and card arm are integrated into the overall case structure, allowing additional card storage capacity without proportionally increasing the external dimensions, thus maintaining portability.

AI summary
A card holder is disclosed, which relates to the technical field of wallets, and includes a case, a card arm, and a cover member. The case includes a first cavity configured to accommodate a card stack including at least two cards. A first card exit is provided on an end wall of the case. The first card exit is in communication with the first cavity. The card arm is arranged in the first cavity, and is configured to push the card stack out of the first card exit, such that at least some of the cards in the card stack are stacked in a dispersed state outside the first cavity. The cover member is arranged on an outer side of a side wall of the case. The cover member is configured in such a manner that a second cavity configured to receive at least one card.
