Rotatable Display Keyboard Leg Mechanism for Tablet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible tablet personal computers face stability and damage issues when used as tablets due to the keyboard and click pad coming into direct contact with hard surfaces, leading to potential scratching and instability.
Innovation Solution
An electronic device with a hinge mechanism and leg portions that protrude or retract from the main body in response to rotational movement, providing structural stability and protection by adjusting the position of the keyboard and click pad relative to the surface it is placed on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the convertible PC is changed to a tablet PC mode, then the device can be used in two ways (laptop and tablet modes), but the keyboard and click pad come into direct contact with the hard surface, decreasing stability and increasing likelihood of damage
Solution Approach 1:
The leg portions are designed to dynamically change their state between protruding and retracted positions based on the rotational angle of the display part. When the device transitions from laptop mode (0-180 degrees) to tablet mode (180-360 degrees), the leg portions automatically protrude to provide stability, and retract when not needed, adapting to different usage scenarios.
Solution Approach 2:
The leg portions are automatically deployed or retracted based on the rotational position of the display part without requiring user intervention. The system self-adjusts the support structure according to the device's configuration state, eliminating the need for manual operation.
2Adaptability or versatility
If the convertible PC is changed to a tablet PC mode, then the device can be used in two ways (laptop and tablet modes), but the keyboard and click pad come into direct contact with the hard surface, increasing likelihood of scratching or damaging
Solution Approach 1:
The leg portions act as intermediary elements between the keyboard/click pad and the hard surface. When protruding, they create a physical barrier that prevents direct contact between the vulnerable components and the desk surface, thereby reducing scratch and damage risk.
3Reliability
If leg portions are added to provide stability, then structural stability is improved, but device complexity increases
Solution Approach 1:
The leg portions are integrated with the hinge mechanism, combining two functions into a single mechanical system. The hinge mechanism not only enables rotation between laptop and tablet modes but also controls the deployment of leg portions, reducing overall structural complexity.
Solution Approach 2:
The hinge mechanism serves multiple functions: it enables rotational movement between usage modes and simultaneously controls the deployment of leg portions. This multi-functionality reduces the need for separate mechanisms, thereby reducing device complexity.

AI summary
An electronic device capable of maintaining a high level of operability and which prevents damage to the keyboard and other input systems when converted from a laptop PC to a tablet PC. The electronic device includes a main body part having a keyboard and a display part having a display. The main body part and the display part may rotate from a 0-degree position where the display and the keyboard face each other up to a 360-degree position where the back faces of the display and the keyboard face each other through a 180-degree position where the display and the keyboard are parallel with each other while facing the same direction. The electronic device includes an upper leg portion that can advance and retreat from an upper face of the main body part in response to rotational movement of the display part from the 180-degree position to the 360-degree position.
