Adjustable Keyboard Stand with Diagonal Movement for Ergonomic Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic keyboard instruments are not suitable for children as they cannot maintain a stable posture due to the pedals being out of reach, and users of all ages face poor handleability due to the need to adjust and reattach additional legs for different seating positions, such as sofas or stools.
Innovation Solution
An electronic musical instrument with a main body supported by a lower and upper stand portion that can be adjusted in height, allowing the instrument to be fixed at a new height, eliminating the need for supplemental parts, and featuring a pedal unit that can be operated comfortably from any seating position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the height of the keyboard is lowered to allow children to play, then children can reach the pedals, but the keyboard moves backward when the user sits on a sofa, causing poor handleability
Solution Approach 1:
The keyboard is designed to move diagonally forward when height is lowered, and the stand portions allow dynamic adjustment of both height and front-back position. This dynamic positioning capability enables the keyboard to adapt to different seating positions (stool, sofa, floor) while maintaining proper playing distance and pedal accessibility.
Solution Approach 2:
The system allows independent adjustment of two parameters: height (vertical position) and front-back distance (horizontal position). By changing these parameters, the keyboard can be positioned optimally for different users and seating arrangements, resolving the contradiction between accessibility and adaptability.
2Adaptability or versatility
If additional legs are mounted to adjust keyboard height, then users can play while sitting on a stool, but users must mount or remove legs each time they change seating position
Solution Approach 1:
Instead of static additional legs that must be mounted and removed, the invention uses a dynamic stand portion system that allows continuous adjustment of height and position. The upper and lower stand portions can be freely repositioned along guide rails, enabling users to adjust the keyboard for different seating positions without mounting or removing components.
Solution Approach 2:
The stand portion system serves multiple functions: it provides height adjustment, front-back position adjustment, and stability for various seating arrangements. This multi-functional design eliminates the need for separate additional legs for different seating positions, improving ease of operation while maintaining versatility.
3Ease of operation
If the keyboard is positioned for adult users, then adults can play comfortably, but children cannot reach the pedals to play stably
Solution Approach 1:
The system allows independent adjustment of height and front-back distance parameters. For children, both parameters can be reduced to lower the keyboard and bring pedals within reach. For adults, the parameters return to standard positions, maintaining playing comfort. This dual-parameter adjustment resolves the contradiction between adult comfort and child accessibility.

AI summary
To the undersurface of a main body 10 having a keyboard 12 operated with player's hands, upper stand portions 72 which are tilted backward and are shaped like a tube are fixed. Lower stand portions 74 are shaped like a tube which is slightly smaller than the upper stand portions 72. The top end of the lower stand portion 74 is inserted into the upper stand portion 72. If the lower stand portions 74 are inserted into the upper stand portions 72 further deeply, the main body 10 is lowered with the main body 10 moving frontward. As a result, even in a case where a player 90 sits on a sofa or the like, the player 90 is allowed to play an instrument in a comfortable posture.
