Hinged Card Storage Mobile Phone Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face discomfort from carrying separate mobile phone cases and card wallets, as mobile phones are not designed to store essential cards like transportation, credit, discount, and point cards, leading to external shocks and increased costs due to the need for additional accessories.
Innovation Solution
A mobile phone case with a hinge structure on the rear side that allows easy storage and retrieval of cards, featuring a card mounting part, a main body cover with a card storing region, and an opening/closing mechanism operated by a hinge member, which also protects the phone and prevents scratches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone case is designed to store cards, then the need for separate card wallets is eliminated, but the device complexity increases
Solution Approach 1:
The patent combines the mobile phone case with a card storage function by integrating a card mounting part directly into the case structure. The card storing region is formed within the case body, allowing cards to be stored without requiring a separate card wallet. This merging of functions eliminates the need for multiple separate accessories while maintaining a relatively simple overall structure.
Solution Approach 2:
The mobile phone case is designed to perform multiple functions: protecting the mobile phone, storing cards, and providing easy access to cards through the opening/closing mechanism. The hinge structure enables the case to serve both as a protective cover and as a card storage system with easy access, making it a universal solution for both phone protection and card management.
2Ease of operation
If a hinge structure with opening/closing mechanism is added for easy card access, then card retrieval convenience is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a hinge structure that enables dynamic opening and closing of the card storage compartment. The hinge allows the main body cover to rotate between a closed position (for protection) and an open position (for card access), transforming the static case into a dynamic system that adapts to user needs while maintaining structural simplicity.
Solution Approach 2:
The case is divided into separable components: the case main body, the main body cover, and the opening/closing cover connected by a hinge. This segmentation allows the card storage function to be accessed independently through the opening mechanism without requiring complete disassembly or complex interaction, simplifying the overall operation while maintaining ease of access.
3Volume of moving object
If the main body cover is spaced apart from the card mounting surface, then card storage space is created, but the structural stability decreases
Solution Approach 1:
The patent creates card storage space by spacing the main body cover from the card mounting surface in the vertical dimension, rather than increasing horizontal dimensions. This vertical spacing accommodates cards while maintaining a compact overall footprint. The hinge structure and opening/closing mechanism are designed to maintain proper alignment and stability despite this vertical separation, allowing the cover to rotate while keeping the card mounting area stable and accessible.

AI summary
The present disclosure relates to a card storage mobile phone case including: a case main body including a front surface, on which a mobile phone storing part, in which attachment/detachment of a mobile phone is performed in a form of surrounding a rear surface and side surfaces of the mobile phone, is formed, and a rear surface which is provided with a card mounting part having a card mounting surface, and including a hinge structure in a lower portion of the rear surface; a main body cover fitted and coupled to the rear surface of the case main body in a state of surrounding the rear surface of the case main body, and including a card string region in which a bottom part of a front surface the main body cover is spaced a predetermined distance apart from a card mounting surface of the card mounding part of the case main body so as to store a card, and an opening which is provided on a lower portion of the main body cover and through which the card is stored and taken out; and an opening/closing cover including a hinge coupling part coupled to the hinge structure with the main body cover therebetween, and configured to open/close the opening.
