Portable Document Holder with Magnetic Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document holders for vehicles do not allow easy viewing or access of tangible documents by third persons exterior to the vehicle, as they lack the ability to reversibly attach to both interior and exterior surfaces without damaging the surfaces and require manual handling by the driver or passenger for display.
Innovation Solution
A portable document holder with a combination of adhesive and magnetic segments that can reversibly attach to various surfaces, including curved or flat metal surfaces, without leaving residue, allowing for quick transfer between interior and exterior vehicle surfaces, and featuring transparent compartments for easy document viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a document holder uses adhesive attachment to secure documents in a vehicle, then the document holder remains stationary and accessible, but the adhesive may damage the vehicle surface or leave residue upon removal
Solution Approach 1:
The document holder is divided into multiple functional segments: a flexible body portion, a removable cover, and distinct adhesive/magnetic attachment regions. This segmentation allows the holder to attach securely through adhesive or magnetic segments while enabling clean removal without surface damage.
Solution Approach 2:
The patent introduces magnetic segments as an intermediary attachment mechanism that can replace adhesive on metal surfaces. The magnetic segments provide secure attachment to vehicle interiors with painted or metallic surfaces without requiring adhesive, thereby preventing surface damage and residue.
2Ease of operation
If a document holder is designed for interior vehicle attachment only, then it provides easy document access for drivers, but it does not enable exterior viewing by third persons such as law enforcement officers
Solution Approach 1:
The document holder is designed with universal attachment capability to function in multiple locations: interior vehicle surfaces (dashboard, windshield) for driver access, and exterior vehicle surfaces for law enforcement viewing. The flexible body and removable cover enable the holder to be positioned and oriented for different viewing contexts.
Solution Approach 2:
The document holder incorporates a removable cover that can be opened or closed dynamically. This allows the holder to transition between states: closed for secure attachment and transport, and open for document insertion/removal. The flexible body also allows dynamic positioning adjustments to optimize viewing angles for different locations.
3Stability of the object's composition
If a document holder uses rigid attachment structures, then it provides stable document display, but it cannot be rapidly transferred between different vehicle surfaces
Solution Approach 1:
The document holder employs a flexible body made of thin film material that can conform to various curved or flat vehicle surfaces. This flexible construction allows rapid transfer between locations while maintaining stable document display when attached, as the flexible material adapts to the surface geometry and secures documents through the cover mechanism.
4Object-generated harmful factors
If a document holder uses opaque compartments, then it protects documents from view, but it prevents easy viewing by third persons
Solution Approach 1:
The document holder features transparent or translucent compartments specifically in the document display areas, while the body portions and cover can be opaque. This local quality differentiation allows third persons to view documents through the transparent compartments when needed, while maintaining privacy protection in other areas when the cover is closed.
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
Enables secure, residue-free attachment and rapid transfer of documents between vehicle surfaces, allowing third persons to view documents without manual intervention by the driver or passenger, even in adverse weather conditions, and supports attachment to diverse materials like glass, paint, and metal.
Implementation Method 1
a magnetic segment for attachment to a metal surface
Implementation Method 2
an adhesive segment for attachment to a non-metal surface

AI summary
The document holder described herein is portable and comprises tangible document compartments for reversible insertion of tangible documents. Each tangible document compartment preferably attaches to an integral uppermost holder layer while it horizontally and laterally aligns with each remaining adjacent tangible document compartment. The document holder is flexible and comprises magnetic components and attaching components that reversibly attach to a curved surface or a flat surface. When initially attached to an interior curved or flat vehicle surface, the document holder is rapidly manually removed and reattached to the exterior curved or flat surface of the same vehicle. A third person exterior to the vehicle may then read or access the tangible documents without a driver or passenger manually retrieving the documents from the vehicle's interior.
