Protective Case Magnets for E-Reader Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices, such as electronic reading devices, often lack a built-in stand for ergonomic viewing, requiring external accessories to maintain an upright position, which can be inconvenient and not universally compatible.
Innovation Solution
A protective case with a foldable design that includes a back cover and a front cover with magnets and metal plates, allowing the device to be secured and converted into a stand, supporting the device at an inclined angle for comfortable viewing without the need for external accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external accessories are used to prop the device in an upright position, then ergonomic viewing is achieved, but device complexity and inconvenience increase
Solution Approach 1:
The patent combines the protective case and stand function into a single integrated unit. The front cover of the protective case is designed to fold back and support the device at an inclined angle, eliminating the need for separate external accessories while providing both protection and ergonomic viewing capabilities.
Solution Approach 2:
The protective case serves multiple functions: it protects the device from damage and simultaneously acts as a stand for ergonomic viewing. This multi-functional design reduces the number of separate accessories needed and simplifies the overall system.
2Reliability
If magnets and metal plates are used to secure the device, then device stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The magnetic securing mechanism automatically holds the front cover in the desired inclined position without requiring precise manual adjustment or complex assembly procedures. The magnets and metal plates create a self-aligning system that maintains stability while reducing the stringency of manufacturing precision requirements.
3Ease of operation
If the protective case is designed to fold into a stand, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The protective case is divided into distinct segments (front cover and back cover) connected by a hinge, allowing the front cover to fold back independently and form a stand. This segmentation enables the stand functionality while keeping each individual component relatively simple in 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 protective case effectively secures the device and provides a stable, adjustable stand for both portrait and landscape orientations, enhancing user experience by eliminating the need for additional accessories and ensuring device protection.
Implementation Method 1
The front cover includes a plurality of magnets, each of the plurality of magnets being disposed in a predetermined location and one or more of the plurality of magnets being positioned based on the location of one or more corresponding metal plates
Implementation Method 2
The front cover also includes a Hall sensor magnet positioned on top of a magnet shielding, wherein the Hall sensor magnet is positioned between the magnet shielding and the back cover of the protective case when the protective case is in a closed position
