Detachable Tablet Hinge With Friction Teeth And Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer arrangements with detachable tablet and base parts have complex hinge mechanisms that restrict full rotation (360°) and limited positional adjustment, compromising functionality and compactness.
Innovation Solution
A hinge arrangement with two pairs of teeth and a friction hinge mechanism, featuring interlocking tooth elements and a distribution cylinder, allows for 360° rotation and adjustable positioning of the tablet part relative to the base part, along with a locking device for secure coupling and decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex hinge mechanism is used to connect the tablet part to the base part, then the tablet can be detachably connected to the base, but the device complexity increases and full 360° rotation is not allowed
Solution Approach 1:
The hinge arrangement is divided into separate components: a hinge unit with toothed elements for mechanical connection and a separate locking device with a locking pin for securing the connection. This segmentation allows each component to perform its specific function independently, reducing overall complexity while maintaining reliable detachable connection.
Solution Approach 2:
A locking pin acts as an intermediary element that bridges the hinge unit and the tablet part. The locking pin engages with a receptacle to secure the tablet part to the base part, providing a simple yet reliable locking mechanism that avoids complex hinge designs while ensuring stable connection.
2Adaptability or versatility
If a friction hinge arrangement with toothed elements is used, then adjustable positioning is enabled, but the device complexity increases
Solution Approach 1:
The friction hinge arrangement utilizes friction between the toothed elements and the pivoting bar to automatically maintain positioning without requiring additional locking mechanisms or complex control systems. The friction force itself provides the positioning function, allowing the tablet part to be adjusted to different angles and held in place through the inherent friction characteristics of the toothed engagement.
3Stability of the object's composition
If the tablet part is permanently connected to the base via a connecting structure, then structural stability is improved, but adaptability decreases
Solution Approach 1:
The connection between the tablet part and base part transitions from a fixed permanent connection to a dynamic detachable connection. The hinge arrangement with locking device allows the connection state to change between locked (stable) and unlocked (detachable) conditions, providing both structural stability when connected and adaptability when detachment is needed, thus resolving the contradiction between stability and versatility.
