Armrest-Mounted Split Keyboard With Detachable Angle-Adjustable Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ergonomic keyboard devices are not adaptable to general chair armrests and lack expandability, limiting their usability and requiring special armrests or entire chair replacement, which restricts user flexibility and adds cost.
Innovation Solution
A keyboard set comprising detachable supports and multidirectional angle adjusting mechanisms, allowing the keyboard to be mounted on general chair armrests and desktops, with expandability options such as USB connectors for additional devices, and pivoting members for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard is designed to be mounted on general chair armrests with detachable supports, then the adaptability and ease of operation are improved, but the device complexity increases due to the additional mounting mechanisms
Solution Approach 1:
The keyboard system is divided into separate components: the keyboard unit and the detachable support, allowing the support to be adapted to different chair armrests while keeping the keyboard unit simple and reusable
Solution Approach 2:
The detachable support is designed with a universal mounting mechanism that can attach to various chair armrest shapes, making the keyboard adaptable to different chairs without requiring chair replacement
2Ease of operation
If the keyboard is designed as an integral combination with chair armrests, then the ease of operation and ergonomic support are improved, but the adaptability worsens as it cannot be moved to desktop or used with other chairs
Solution Approach 1:
The keyboard and support are designed as separable components rather than a permanent integral structure, enabling the keyboard to be moved between different locations (chair armrests and desktops) while maintaining ergonomic support when mounted on chairs
Solution Approach 2:
The detachable support provides a dynamic mounting solution that transitions between attached and detached states, allowing the keyboard to adapt to different usage scenarios (portable chair mounting vs. stationary desktop use)
3Reliability
If special armrest members are used to mount the keyboard, then the reliability of mounting is improved, but the ease of operation and cost worsen due to requiring chair replacement
Solution Approach 1:
The detachable support is designed to self-adapt to various chair armrest shapes through its flexible mounting mechanism, eliminating the need for special armrest members or chair replacement while maintaining reliable mounting
4Device complexity
If the keyboard has limited space on chair armrests, then the device complexity is reduced, but the adaptability worsens as additional input devices cannot be added
Solution Approach 1:
The detachable support structure provides nested or stacked mounting capability where additional input devices can be arranged vertically or in layers on the chair armrest, maximizing space utilization while maintaining structural simplicity

AI summary
A keyboard set may be provided on chair armrests.The keyboard set includes a left keyboard, a right keyboard, a first detachable support, a second detachable support, and two multidirectional angle adjusting mechanisms. Each of the left keyboard and the right keyboard includes a plurality of keys. One end of the first detachable support is combined with the left keyboard, and one end of the second detachable support is combined with the right keyboard. The two multidirectional angle adjusting mechanisms are respectively provided between the first detachable support and the left keyboard, and between the second detachable support and the right keyboard.
