Ergonomic Keyboard With Dual-Axis Adjustment Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ergonomic keyboards in prior art often restrict users to adjusting only one angle, either rotation or height, which can lead to user discomfort and increased risk of carpal tunnel syndrome due to inadequate alignment with the user's hand position.
Innovation Solution
An ergonomic keyboard design featuring a pivotally connected adjustment module with a rotary knob, adjustment screw, and supporting base, allowing simultaneous adjustment of rotation and inclination angles between key areas, enabling users to customize the included and inclination angles for improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the keyboard structure is simplified to allow only one angle adjustment, then the device complexity is reduced, but the adaptability to different user hand positions deteriorates
Solution Approach 1:
The adjustment module is divided into two independent adjustment mechanisms: one for rotating the first key area and another for tilting the second key area. This segmentation allows each mechanism to handle a specific adjustment function, reducing the complexity of a single integrated mechanism while providing comprehensive angle adjustment flexibility for different user hand positions.
2Adaptability or versatility
If multiple adjustment mechanisms are integrated into one module, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
Two separate adjustment mechanisms (rotation adjustment for first key area and tilting adjustment for second key area) are merged into a single adjustment module. This merging allows both adjustment functions to be integrated in one location, improving adaptability by enabling simultaneous angle adjustments while keeping the overall structure compact and manageable.
3Ease of operation
If the keyboard allows simultaneous adjustment of rotation and inclination angles, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The adjustment module incorporates dynamic adjustment capabilities where the first key area can rotate and the second key area can tilt independently. This dynamic design allows users to easily adjust the keyboard to different angles and positions for optimal comfort, while the modular structure keeps the complexity manageable by separating the adjustment functions into distinct mechanisms within the same module.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to adjust the ergonomic keyboard's angles to reduce strain on wrists and tendons, thereby minimizing the risk of carpal tunnel syndrome by allowing for customizable alignment and support, enhancing user comfort and reducing discomfort during prolonged use.
Implementation Method 1
The adjustment screw is fixedly connected to the rotary knob in order to rotate together with the rotary knob. The supporting base is supported on a flat surface and is provided with internal threads to screw with the adjustment screw. When the rotary knob rotates, the adjustment screw and the internal thread of the supporting base can rotate mutually for adjustment of an inclination angle between the first and the second key areas and the flat surface.
Implementation Method 2
The first bearing is pivotally connected to the first key area by the first connecting shaft. The second bearing is pivotally connected to the first bearing and is pivotally connected to the second key area by the second connecting shaft. The first bearing and the second bearing can rotate relative to each other for adjustment of an included angle between the first key area and the second key area.

AI summary
An ergonomic keyboard is disclosed. The ergonomic keyboard includes a first key area, a second key area and an adjustment module. The adjustment module is pivotally connected between the first key area and the second key area. The adjustment module includes a first bearing, a second bearing, a rotary knob, an adjustment screw and a supporting base. The first and second bearings are pivotally connected to the first and second key areas respectively such that they allow adjustment of an included angle. The adjusting screw is fixedly connected to the rotary knob and can be rotated together with the rotary knob. The supporting base is supported on a plane, and an internal thread of the supporting base and the adjusting screw are screwed with each other. Thus, an inclination angle of the first and second key areas can be adjusted by the rotary knob.
