Hinged File Cover with Bendable Pocket for Secure 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, as they require careful orientation to prevent the opening from facing downwards.
Innovation Solution
A file design featuring a cover body with rotatable sections connected via a hinge, allowing the pocket body to be bent and housed between the cover sections, increasing friction and preventing items from falling, while also reducing the overall size of the file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the width of the cover body is made larger than the width of the pocket part to protect the stored item, then the protection performance is improved, but the file size becomes larger than necessary
Solution Approach 1:
The pocket body is designed to be flexible and deformable, allowing it to dynamically adapt its shape during the closing process. The pocket body can be elastically deformed to fit within the reduced width of the closed cover body, eliminating the need for excessive width while maintaining protection capability through the flexible adaptation to the compact form.
2Ease of operation
If the file is made compact to improve portability, then the convenience of carrying is improved, but the stored item may drop out when the opening faces downward
Solution Approach 1:
The opening part of the pocket body is positioned at a specific location that prevents the stored item from dropping out regardless of the file's orientation. The opening is configured to face a direction that utilizes gravity and friction to keep the item securely inside, counteracting the potential harmful effect of the opening facing downward during carrying.
3Stability of the object's composition
If the pocket body is made with a fixed rigid structure to maintain shape, then the structural stability is improved, but the file size becomes larger and less flexible
Solution Approach 1:
The pocket body is constructed from flexible material that can elastically deform and adapt to the compact closed form of the cover body. This flexible structure maintains sufficient structural stability to hold and protect the stored item while allowing the file to be compact in size when closed, eliminating the need for a rigid fixed structure.
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 design enhances convenience by reducing the file's size and preventing items from dropping, even when carried with the opening facing downwards, due to increased friction and secure storage.
Implementation Method 1
a spine section provided between the first cover section and the second cover section and connected to the first cover section and the second cover section via a hinge part
Implementation Method 2
the stored item naturally drops down from the opening part of the pocket part... due to increased friction and secure storage

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 fixed part is provided on an external side of the storage part in a plan view and fixed to the cover body. The pocket body is bendable together with the cover body while the stored item is in the pocket body.
