File With Bendable Pocket Body For Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional files with pocket bodies attached to cover bodies are inconvenient due to their larger size and the risk of items stored in the pocket dropping when carried unintentionally, as they require attention to the direction of carrying to prevent items from falling out.
Innovation Solution
A file design featuring a cover body with rotatable sections and a pocket body that extends between these sections, allowing the pocket to be bent and housed within the cover body, increasing friction and reducing the overall size of the file while preventing items from falling out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover body width is made larger than the pocket part width to protect stored items, then protection performance is improved, but the file size becomes larger than the item area
Solution Approach 1:
The pocket body is designed to be movable relative to the cover body through holding members that allow limited movement. When the file is carried in different orientations, the pocket body can shift position dynamically, ensuring the opening part remains at the top due to gravity, preventing items from falling out while maintaining a compact file size
2Ease of operation
If the file size is reduced to improve portability, then convenience is improved, but the pocket body cannot adequately protect stored items
Solution Approach 1:
The pocket body is nested within the cover body structure, with the holding members integrated into the cover body. This nested configuration allows the pocket body to be securely positioned within the compact file structure while still providing adequate protection for stored items through the movable design
3Reliability
If the pocket body is made fixed to ensure item security, then reliability is improved, but items may fall out when carried in unintended directions
Solution Approach 1:
The holding members are designed to allow the pocket body to move dynamically within the cover body. This movement capability enables the pocket body to automatically orient itself with the opening part at the top when the file is carried in any direction, preventing items from falling out while maintaining item security through the constrained movement range
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
The file achieves a smaller size and enhanced convenience by allowing the pocket body to be bent within the cover body, reducing the likelihood of items falling and improving usability without needing to consider the carrying direction.
Implementation Method 1
allowing the pocket to be bent and housed within the cover body, increasing friction

AI summary
A file includes a cover body and a pocket body attached to the cover body. The cover body includes a front cover section, a spine section, and a back cover section. The front cover section and the back cover section are rotatable relative to each other about the spine section via a hinge part so as to face each other. The pocket body includes a storage part arranged to extend from the front cover section to the back cover section and allowing storage of an item to be stored. A held part is provided on an external side of the storage part in a plan view. The front cover section further includes a holding member for holding the held part movably. The pocket body is bendable together with the cover body while the stored item is in the pocket body.
