Notebook Computer Pivot Display Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers have a display screen that is too close to the keyboard, requiring users to adopt an ergonomically incorrect posture, leading to potential shoulder and neck strain due to the need to lower their head to view the screen, which is not suitable for long-term use.
Innovation Solution
A notebook computer design that allows the display body to be adjusted in height and angle through a pivot connection system, enabling the display to be rotated and translated relative to the host, allowing for multiple use modes, including a second unfolded state that increases the horizontal height of the display for comfortable viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display screen is positioned close to the keyboard in a conventional notebook computer, then the device maintains a compact and simple structure, but the user must adopt an incorrect posture (bowing head) to view the screen, causing shoulder and neck strain
Solution Approach 1:
The patent applies the dynamics principle by making the display body adjustable through pivot connections, allowing it to rotate and translate between different positions. The display can switch between a first unfolded state (close to keyboard) and a second unfolded state (away from keyboard), enabling users to adjust the viewing angle and distance according to their needs, thus eliminating the need to bow the head while maintaining structural flexibility
Solution Approach 2:
The patent segments the display assembly into separate components: the display body, the functional body, and the host, connected through pivot joints. This segmentation allows the display body to be independently adjusted relative to the keyboard portion, enabling the display to be positioned at optimal viewing distances without compromising the overall device structure
2Volume of moving object
If the display screen is positioned close to the keyboard, then the notebook computer maintains a compact form factor, but long-term use causes injury to the user's body
Solution Approach 1:
The patent enables the display body to dynamically adjust its position through pivot connections, allowing users to switch between a compact first unfolded state and an ergonomic second unfolded state. In the second state, the display body translates away from the keyboard portion, increasing horizontal height and allowing users to view the screen at a comfortable distance without bowing their head, thereby eliminating body injury risks while maintaining compactness when needed
3Ease of operation
If the display body is translated along the receiving portion to adjust angle, then viewing comfort is improved, but the mechanism complexity increases
Solution Approach 1:
The patent uses pivot connections to enable dynamic adjustment of the display body's position and angle. The functional body pivots relative to the host, and the display body pivots relative to the functional body, creating a chain of movable joints that allow smooth translation and rotation. This dynamic mechanism achieves viewing angle adjustability while maintaining relatively simple pivot joint structures

AI summary
Provided is a notebook computer with a functional body, including a host, a functional body and a display body. The host has a keyboard portion and a receiving portion, and a height difference is formed between the keyboard portion and the receiving portion. The functional body has a first end and a second end. The first end is in pivot connection to the keyboard portion of the host. The display body has a display portion and a base. The second end of the functional body is in pivot connection to the display body. The display body is adapted to be rotated relative to the host and the functional body, so that the base is in contact with the receiving portion to switch to a folded state or a first unfolded state. The functional body is adapted to be rotated relative to the host, so that the base of the display body is relatively away from the receiving portion to switch to a second unfolded state.
