Notebook Display Panel Stabilization via Linkage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior notebook computers with a single rotary shaft coupling the base and display panel suffer from instability when the display panel is turned to an operation position, leading to wobbling and unbalanced conditions, making it difficult for users to work smoothly.
Innovation Solution
The implementation of additional plate members that form a linkage system, allowing the top cover to pivotally turn relative to the base, with the second and third plate members cooperatively supporting the display panel to prevent wobbling by displacing and stabilizing it at the operation position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotary shaft is used to couple the base and display panel, then the device complexity is reduced, but the stability of the display panel deteriorates causing wobbling
Solution Approach 1:
The single rotary shaft coupling system is segmented into multiple components: a first rotary shaft for pivotal connection, and a linkage system comprising first, second, and third plate members with a second rotary shaft. This segmentation allows the display panel to be supported by multiple points rather than a single axis, resolving the wobbling issue while maintaining reasonable structural complexity.
Solution Approach 2:
The invention transitions from a single-axis rotation system to a multi-dimensional linkage system. The plate members extend in multiple directions and the second rotary shaft is positioned at a different height from the first rotary shaft, creating a three-dimensional support structure that stabilizes the display panel across multiple degrees of freedom.
2Ease of operation
If the display panel is turned to operation position, then the usability is improved, but the center of gravity shifts causing unbalanced condition
Solution Approach 1:
The linkage system acts as a counterbalancing mechanism. When the display panel is rotated to the operation position, the plate members and second rotary shaft create a counterbalancing effect that offsets the shift in center of gravity, maintaining overall balance and preventing the notebook from becoming unstable during use.
Solution Approach 2:
The linkage system dynamically adapts to the display panel's position. As the panel rotates from closed to operation position, the plate members move and adjust their configuration, continuously maintaining balance throughout the transition and at the final operating position, rather than being fixed in a single configuration.

AI summary
A notebook computer includes a base; a top cover pivotally coupled via a first rotary shaft to the base and including a display panel disposed at an inner side thereof; a first plate member provided on an outer side of the top cover, a third plate member pivotally coupled at an end to the base via a second rotary shaft; and a second plate member pivotally coupled at an end to the first plate member and slidably coupled at an opposing end to the third plate member, such that the second and the third plate member are displaceable relative to each other. When the top cover is pivotally turned to an operation position, the second end of the second plate member is pushed against the third plate member to restrict the top cover and the third plate member from turning further, and hold the top cover to the operation position.
