Torque Variable Hinge for Hybrid Tablet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid tablet and laptop devices face challenges in rotating the bracket for detachment and attachment, as the rotational torque is either too high to easily rotate when the tablet is detached, making it difficult to store compactly, or too low when mounted, leading to instability.
Innovation Solution
A torque variable structure that adjusts the rotational torque of the bracket at the hinge, reducing torque when the tablet is detached for easy rotation and increasing torque when mounted for stability, using a clutch mechanism and elastic members to facilitate this adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the rotational torque of the bracket at the hinge is increased to stabilize the tablet when mounted, then the tablet becomes stable when attached, but the bracket becomes difficult to rotate when the tablet is detached for storage
Solution Approach 1:
The hinge incorporates a torque variable structure that dynamically adjusts the rotational torque based on whether the tablet is mounted or detached. When the tablet is mounted, the hinge provides high torque for stability. When detached, the torque is reduced to enable easy rotation of the bracket for compact storage. This dynamic adjustment resolves the contradiction between stability during use and ease of operation during storage.
Solution Approach 2:
The patent changes the physical parameter of rotational torque in the hinge mechanism. By using a torque variable structure with clutch mechanisms and elastic members, the system transitions between different torque states: a first torque value when the tablet is mounted (providing stability) and a second, lower torque value when detached (enabling easy rotation). This parameter change directly addresses the technical contradiction.
2Ease of operation
If the rotational torque is reduced to enable easy rotation of the bracket for compact storage, then the bracket becomes easy to rotate, but the tablet becomes unstable when mounted
Solution Approach 1:
The hinge mechanism dynamically switches between low-torque and high-torque modes based on the mounting state. When the tablet is detached, the system operates in low-torque mode for easy bracket rotation. When the tablet is mounted, the torque variable structure automatically transitions to high-torque mode to provide stable mounting. This dynamic behavior resolves the contradiction by applying the appropriate torque level for each operational state.
Solution Approach 2:
The system changes the rotational torque parameter from a fixed value to a variable value that adapts to the operational state. The torque variable structure, incorporating clutch mechanisms and elastic members, enables the hinge to provide a first torque value when the tablet is mounted and a second, lower torque value when detached, thereby resolving the stability-ease of operation contradiction.
3Stability of the object's composition
If a fixed high rotational torque is applied at the hinge to ensure stable mounting, then the tablet remains stable during use, but the device complexity increases due to the need for torque adjustment mechanisms
Solution Approach 1:
The patent implements a torque variable structure within the hinge that automatically adjusts rotational torque based on the mounting state. This dynamic mechanism uses clutch components and elastic members to provide high torque when the tablet is mounted and low torque when detached. The automatic adjustment capability provides the needed stability without requiring complex external control systems.
Solution Approach 2:
The hinge mechanism incorporates a torque variable structure that changes the rotational torque parameter from fixed to variable. By using clutch mechanisms and elastic members, the system automatically transitions between different torque levels based on whether the tablet is mounted or detached. This parameter change enables stable mounting while keeping the mechanism relatively simple through automatic operation.

AI summary
In an embodiment there is provided an electronic apparatus in which two housings are detachable and rotatable, and in which when one housing is detached from the other housing, and having a bracket for attachment and detachment that is easily rotated. An electronic apparatus may include an upper housing having a display; a lower housing which is rotatably connected with a bracket from which the upper housing is detachable by hinges; and a torque variable structure which changes rotational torque of the bracket at the hinges. The torque variable structure is capable of reducing the rotational torque of the bracket at the hinges in a state in which the upper housing is detached from the bracket, rather than a state in which the upper housing is mounted on the bracket.
