Dual-Axis Hinge Mechanism for Flexible Electronic Device Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices, such as notebook computers, are limited by a single degree of freedom in screen rotation, restricting user flexibility and making it difficult for multiple users to share the display while allowing the primary user to continue operating the device.
Innovation Solution
An electronic device design featuring a first body, a second body, and a base with interconnected shaft structures and a magnetic locking mechanism, allowing the second body to pivot in two different axial directions, enhancing operating flexibility by enabling various viewing angles and operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single degree of freedom rotation mechanism is used, then the device structure is simple, but the viewing angle and operating flexibility are restricted
Solution Approach 1:
The patent transitions from a single-degree-of-freedom rotation mechanism to a dual-degree-of-freedom mechanism by adding a second rotation axis. The first shaft structure enables rotation around a first axis, while the second shaft structure enables rotation around a second axis that is perpendicular to the first axis, allowing the display screen to be viewed from multiple directions and angles simultaneously
2Adaptability or versatility
If the display screen is rotated to face other users, then other users can view the screen, but the primary user cannot watch the images and perform operations
Solution Approach 1:
By introducing a second rotation axis perpendicular to the first, the display screen can be oriented in three-dimensional space to face multiple users simultaneously. The screen can be rotated around the first axis to face one user, and then rotated around the second axis to maintain visibility for the primary user, enabling multi-user viewing without compromising operational accessibility
Solution Approach 2:
The dual-degree-of-freedom rotation mechanism provides dynamic positioning capability, allowing the display screen to be adjusted to optimal viewing angles for multiple users while maintaining the primary user's ability to interact with the device. The independent rotation axes enable flexible reconfiguration of the display orientation during operation
3Ease of operation
If a dual degree of freedom rotation mechanism is implemented, then operating flexibility and viewing angles are improved, but the device structure becomes more complex
Solution Approach 1:
The complex dual-degree-of-freedom rotation mechanism is segmented into independent modular components: a first shaft structure for rotation around the first axis, and a second shaft structure for rotation around the second axis. Each shaft structure can be designed, manufactured, and maintained independently, reducing the overall system complexity despite the enhanced functionality
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 design provides improved operating flexibility, allowing users to easily switch between viewing angles and operating modes, enabling multiple users to view the screen while the primary user continues to operate the device without interference.
Implementation Method 1
the magnetic latch is configured to be subject to a magnetic attraction force of the first magnetic component so as to be positioned in the first latching slot... a magnetic attraction force produced by the second magnetic component to the magnetic latch is greater than a magnetic attraction force produced by the first magnetic component to the magnetic latch

AI summary
An electronic device includes a first body, a second body, a base, a first shaft structure, a second shaft structure, and a locking component. The second body is connected to the first body through the base. The first shaft structure includes a first shaft and a second shaft. The second body is pivoted to a first base portion of the base through the first shaft and a second base portion of the base through the second shaft. The second shaft structure includes a connecting component fixed to the first body and a third shaft pivoted to the first base portion and the connecting component. The first and second shafts are perpendicular to the third shaft. The locking component is slidably disposed between the second base portion and the first body and configured to lock or release a connection between the second base portion and the first body.
