Magnetic Tablet Case for Multi-Angle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computer protective cases with three-fold designs fail to provide stable multi-angle support, as the folds are not deep enough or the protective shell is too thick, leading to instability when the device is placed on a bed or other uneven surfaces.
Innovation Solution
A protective case with embedded magnetic elements on the front plate that can attract a permanent magnet or ferromagnetic element in the tablet computer, forming a stable triangle frame to prop up the device at various angles, allowing for secure and adjustable multi-angle support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a three-fold design is used with shallow folds or thick protective shell, then the protective case can be manufactured with simple structure, but the tablet computer cannot stand firmly against the folded triangle
Solution Approach 1:
The patent replaces the traditional mechanical folding structure with a magnetic attraction system. Magnetic elements are embedded in the protective case and correspond to permanent magnets or ferromagnetic elements in the tablet computer, creating magnetic attraction forces that form a stable triangle frame without relying on deep folds or thin shells, thus solving the stability issue while maintaining manufacturing simplicity
Solution Approach 2:
The patent changes the fundamental support mechanism from geometric folding to magnetic force. By embedding magnetic elements in the protective case and utilizing the magnetic field interaction with the tablet's permanent magnets, the system achieves stable triangular support frames at multiple angles, transforming the support principle from mechanical shape to magnetic force
2Reliability
If magnetic elements are installed on the first surface to create stable triangle frame, then the tablet computer can stand firmly at different angles, but the device complexity increases
Solution Approach 1:
The magnetic elements embedded in the protective case automatically interact with the permanent magnets or ferromagnetic elements in the tablet computer through magnetic attraction, forming stable triangular frames without requiring additional mechanical components, adjustment mechanisms, or complex structural designs, thus achieving multi-angle support with minimal added complexity

AI summary
The present disclosure generally relates to a protective case for a tablet computer, including a front plate (110) having a first surface (111) configured to protect a display surface of the tablet computer, wherein a magnetic element (112) is installed on the first surface (111); a holding plate (120) being configured to hold a back of the tablet computer; a supporting plate (130) connecting the front plate (110) and the holding plate (120) to prop up the tablet computer; wherein the magnetic element (112) can be installed at different positions on the first surface (111), in order to enable the tablet computer to stand up at different angles. The magnetic element (112) installed on the first surface (111) of the front plate (110) is attracted with a bottom end of the tablet computer, thus a steady triangle frame is formed between the tablet computer and the folded protective case, further enabling the tablet computer to stand up at different angles.
