Foldable Phone Case Hinge Cover and Card Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable mobile phone cases fail to effectively protect the hinge portion and cannot accommodate cards securely, leading to potential damage from external forces and loss of cards due to their design limitations.
Innovation Solution
A foldable mobile phone case with an upper body part, lower body part, card storage part, and hinge cover part, featuring specific structures such as recessed grooves, magnetic attachments, and elastic deformation, which allows for stable mounting of the phone, protection of the hinge, and secure storage of cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple protective case structure is used, then the case is easy to manufacture, but it cannot effectively protect the hinge portion and cannot accommodate cards securely
Solution Approach 1:
The case is divided into multiple functional segments: an upper case body for the first housing, a lower case body for the second housing, a hinge cover for the hinge portion, and a card storage case with magnetic closure. Each segment independently addresses specific protection needs while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The hinge cover is rotatably coupled to the lower case body and can be rotated to cover the hinge portion when the mobile phone is folded. The card storage case is nested within the lower case body, utilizing magnetic attraction between the card storage case and lower case body to secure cards while maintaining a compact integrated structure.
2Reliability
If a separate case is mounted on the folded portion, then the hinge portion can be protected, but the device complexity increases
Solution Approach 1:
The hinge cover is integrated with the lower case body through rotatable coupling, combining the hinge protection function with the existing case structure. This eliminates the need for a completely separate protective component while maintaining the ability to protect the hinge portion when the mobile phone is folded.
Solution Approach 2:
The hinge cover is designed to be rotatable relative to the lower case body, allowing it to dynamically adjust its position. When the mobile phone is folded, the hinge cover rotates to cover and protect the hinge portion; when unfolded, it can be positioned to not interfere with the phone's functionality.
3Reliability
If a magnetic attachment structure is used for card storage, then cards can be securely retained, but the manufacturing precision requirements increase
Solution Approach 1:
The card storage case utilizes magnetic attraction between the card storage case and lower case body to automatically secure cards without requiring precise mechanical alignment or additional fastening mechanisms. The magnetic force naturally holds the card storage case in position and secures the cards within it.
