Notebook Computer Rotating Shaft Support Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notebook computers face a challenge in designing a rotating shaft due to insufficient space on the display screen, which conflicts with the location of the drive circuit board, requiring a larger fixing area that is not available.
Innovation Solution
The implementation of a rotating shaft support system within the notebook computer's housing, comprising a first and second rotating shaft support, where the second support partially overlaps with the drive circuit board, allowing for a shared region without increasing the bezel area, and utilizing a dual-fastener assembly for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a notebook computer is made compact and lightweight for portability, then ease of carrying is improved, but the battery capacity and processing power are limited
Solution Approach 1:
The power system is segmented into two independent battery packs (first and second battery packs) that can be used separately or combined. This allows the user to carry only one battery pack for lightweight portability, or both battery packs for extended battery capacity, resolving the contradiction between weight and battery capacity.
Solution Approach 2:
The second battery pack is designed to be detachable and can be carried in a separate portable case, adding a spatial dimension to the power supply solution. Users can distribute the battery packs across different locations (one in the notebook, one in the portable case), effectively increasing total battery capacity without increasing the weight of the notebook itself.
2Ease of operation
If the notebook computer uses a detachable battery pack design, then ease of replacement and portability are improved, but structural complexity increases
Solution Approach 1:
The battery system is divided into a first battery pack integrated with the notebook and a second battery pack in a portable case, both with detachable designs. This segmentation allows simple replacement of individual battery packs without complicating the overall system, as each pack operates independently with its own detachment mechanism.
Solution Approach 2:
The second battery pack is extracted from the notebook system and placed in a separate portable case, simplifying the notebook's internal structure while maintaining ease of replacement. The detachment interface is standardized and simplified, allowing users to swap battery packs without dealing with complex internal connections.
3Duration of action of moving object
If the notebook computer has extended battery capacity, then duration of action is improved, but weight and volume increase
Solution Approach 1:
The total battery capacity is segmented across two separate battery packs instead of one large pack. Each pack can be optimized for lighter weight and compact size, while together they provide extended battery duration. Users can carry both packs for maximum duration or one pack for lighter weight, flexibly resolving the contradiction.
Solution Approach 2:
The portable case containing the second battery pack introduces a separate carrying dimension. The notebook itself remains lightweight, while the extended battery capacity is achieved by adding weight only to the optional portable case, allowing users to pay for extra battery duration only when they actually carry the case.

AI summary
This application discloses a notebook computer, including a display screen, a base, a rotating shaft that connects the display screen and the base, a rotating shaft support that is disposed inside a housing of the display screen and that is connected to the rotating shaft in an assembly manner, and a drive circuit board disposed inside the housing of the display screen. The rotating shaft support includes a first rotating shaft support and a second rotating shaft support. A projection of the drive circuit board and a projection of the first rotating shaft support do not overlap on a plane on which the display screen is located, and the projection of the drive circuit board and a projection of the second rotating shaft support at least partially overlap on the plane on which the display screen is located. This resolves a problem that a disposing location of the rotating shaft support conflicts with a disposing location of the drive circuit board when the rotating shaft support extends from two sides of the display screen of the notebook computer to the middle to a region in which the drive circuit board is located. Therefore, an entire size of the notebook computer is not affected because an area of a bezel region of the display screen of the notebook computer is not increased, and costs are relatively low because the drive circuit board does not need to be modified.
