Movable Cover Hinge Mechanism for Tablet Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with detachable lids face the risk of lid loss and impaired battery attachment/detachment due to the presence of a hinge, which complicates the ease of internal operations.
Innovation Solution
An electronic device design featuring a housing with a fixed cover and a movable cover connected by a hinge shaft, where the support plate allows the movable cover to rotate and move away from the fixed cover, preventing interference and enabling a larger opening angle for improved convenience in battery access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hinge is used to make the lid openable and closable to prevent loss, then the lid can be securely attached, but the ease of attachment and detachment of the battery is impaired
Solution Approach 1:
The cover is divided into a fixed cover and a movable cover that can be separated. The movable cover can be detached from the fixed cover to provide direct access to the battery compartment, eliminating the need to manipulate a hinge mechanism when accessing the battery.
Solution Approach 2:
The cover transitions from a static hinge-connected structure to a dynamic system where the movable cover can be independently detached. This dynamic separation allows the cover to adapt between a closed protective state and an open accessible state for battery operations.
2Device complexity
If the movable cover is opened with a fixed hinge position, then the hinge structure is simple, but interference occurs between the movable cover and fixed cover limiting the opening angle
Solution Approach 1:
The hinge shaft is made movable relative to the fixed cover through the support plate mechanism. As the movable cover opens, the hinge shaft position changes, allowing the opening angle to increase without causing interference between the covers.
Solution Approach 2:
The hinge shaft is allowed to move not only rotationally but also in a directional manner relative to the fixed cover. This additional degree of freedom in the hinge movement enables larger opening angles while maintaining structural simplicity.
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
This configuration enhances user convenience by allowing a larger opening angle of the movable cover, reducing interference and making battery attachment and detachment easier while preventing damage to the covers.
Implementation Method 1
a hinge shaft that is disposed between a first edge of the fixed cover and a second edge of the movable cover that are adjacent to each other, and supports the movable cover
Implementation Method 2
The support plate is movably attached to the inner chassis to enable the hinge shaft to move away from the first edge of the fixed cover

AI summary
A tablet computer (an example of an electronic device) includes a housing that contains an electric component, the housing including a fixed cover and a movable cover that constitute adjacent regions of a back surface of the housing, a hinge shaft that is disposed between a front edge of the fixed cover and a back edge of the movable cover that are adjacent to each other and supports the movable cover, and a first attachment plate that supports the movable cover rotatably about the back edge. The first attachment plate is movably attached to an inner chassis to which the fixed cover is fixed such that the hinge shaft is movable away from the front edge of the fixed cover.
