Notebook Upper-Cover Angle Control with Sensor-Based Presets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of notebook computers face inconvenience due to varying angle preferences for the upper cover, leading to uneven pressure and potential damage, and the need for repeated adjustments, as well as time-consuming activation of power functions.
Innovation Solution
A notebook computer equipped with shortcut keys and an angle sensor that allow for quick and convenient angle adjustments by binding different keys to specific angles, enabling automatic opening and closing of the upper cover based on user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of the upper cover angle is used, then the user can find the preferred angle, but it leads to uneven pressure on the screen and potential damage to hinges or display
Solution Approach 1:
The system automatically adjusts the upper cover angle based on sensor feedback and pre-set preferences, eliminating manual intervention. The computer self-regulates the angle to prevent uneven pressure on the screen and hinges while maintaining user-preferred viewing angles.
Solution Approach 2:
The system uses sensors to detect the current angle of the upper cover and provides feedback to the control unit. Based on this feedback and pre-set user preferences, the system automatically adjusts the angle, creating a closed-loop control system that prevents damage while maintaining optimal positioning.
2Adaptability or versatility
If manual angle adjustment is required for different usage scenarios, then the user can optimize for each scenario, but it requires multiple adjustments and is inconvenient
Solution Approach 1:
The system pre-sets multiple angle preferences corresponding to different usage scenarios (e.g., typing, viewing, presentation modes). When a scenario is detected or selected, the system automatically applies the pre-configured angle, eliminating the need for users to manually adjust the angle for each usage scenario.
Solution Approach 2:
The system provides multiple pre-configured angle preferences that serve different usage scenarios. A single automated system handles all scenario-based angle adjustments, making the angle adjustment mechanism universal across various usage contexts without requiring separate manual adjustments for each scenario.
3Device complexity
If the power button can only be activated after opening the upper cover, then the design is simple, but it is time-consuming to activate power and software
Solution Approach 1:
The power button is positioned on the lower base and can be pressed before the upper cover is opened. The system detects the power button press in advance and begins the power-on sequence, allowing the computer to start up simultaneously with or before the cover is fully opened, thus saving time.
Solution Approach 2:
The power button functionality is extended to work in both closed and open cover states. By placing the power button on the lower base rather than requiring cover opening first, the system adds the capability of pre-activation, transforming the power activation process from a sequential two-step operation to a concurrent operation.

AI summary
The invention provides a notebook computer capable of conveniently adjusting an angle of an upper cover thereof, and a method for adjusting the angle of the upper cover. The notebook computer is equipped with a plurality of shortcut keys and an angle sensor. A user may bind different shortcut keys to different angles through a first operation, with the angles detected by the angle sensor. When the user performs a second operation on a specific shortcut key, the upper cover can be rotated to a position corresponding to a specific angle, enabling quick and convenient adjustment of the angle of the upper cover for different usage scenarios, while also preventing potential damage to the notebook computer.
