Automatic Keyboard Tilt Adjustment for Ergonomic Hand Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience fatigue and discomfort due to non-ergonomically positioned keyboards, which are typically manually adjusted and limited to fixed positions, failing to provide optimal comfort and convenience, especially for clamshell and external keyboard form factors.
Innovation Solution
A system that uses sensors to determine the ergonomic position of a user's hands and the keyboard relative to the surface, adjusting the keyboard's tilt angle automatically to enhance ergonomics, utilizing sensors on wrist and palm rests, pressure sensors, and orientation sensors to analyze and adjust the keyboard's position for optimal comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyboard position is fixed relative to device base, then device structure is simple, but user comfort and ergonomics deteriorate
Solution Approach 1:
The patent implements dynamic keyboard positioning by enabling the keyboard to move relative to the device base along a defined path. The keyboard position is no longer fixed but can be adjusted automatically based on detected hand positions, transforming the static structure into a dynamic system that adapts to user needs while maintaining reasonable structural complexity through guided motion constraints.
Solution Approach 2:
The system employs sensors to detect user hand positions and automatically adjusts the keyboard position without requiring manual intervention. The device serves itself by autonomously determining the optimal keyboard position based on detected hand coordinates, eliminating the need for users to manually adjust keyboard projections or reposition the device.
2Measurement precision
If manual keyboard adjustment is provided, then device complexity is low, but adjustment precision and ergonomics deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated sensor-based system. Sensors detect hand positions with high precision, and this detection data drives automatic keyboard repositioning, substituting the crude mechanical adjustment process with a more precise sensor-measure-control loop that improves measurement precision while accepting increased device complexity.
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously monitor hand positions and provide this information to the control system, which then adjusts the keyboard position accordingly. This closed-loop feedback ensures high measurement precision by constantly comparing detected hand positions with the current keyboard position and making corrective adjustments.
3Adaptability or versatility
If keyboard tilt is manually adjusted, then ease of manufacture is high, but adaptability to different users deteriorates
Solution Approach 1:
The patent utilizes parameter changes by detecting hand position coordinates and translating them into specific keyboard position adjustments. The system dynamically changes the keyboard's position parameters (x, y coordinates and tilt angle) based on detected hand positions, enabling adaptation to different users and usage scenarios while incorporating sensors and actuators that increase manufacturing complexity.

AI summary
Examples apparatus, systems, articles of manufacture and methods to adjust a keyboard position are disclosed. An example keyboard position adjustment system includes a keyboard orientation detector to determine a first keyboard position of a keyboard and/or a hand position detector to determine a hand position near the keyboard. The example system also includes an adjuster to move the keyboard to a second keyboard position based on the first keyboard position and/or the hand position.
