Double-Ended Keyboard Device With Rotating Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic keyboards, such as keytars, are limited in their design, allowing only single-handed operation and limited tonal control, making them impractical for two-handed use and restricting the range of musical expressions that can be generated.
Innovation Solution
A double-ended keyboard device with two separate keyboard sections, one for each hand, arranged in opposite directions and connected by a joint that allows rotation, enabling independent operation and control of both hands, with a control unit that generates sound and control outputs based on input from both sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single keyboard is used on a keytar, then the device can be worn and played while standing, but the number of keys and tonal control is limited
Solution Approach 1:
The keyboard device is divided into two separate keyboard sections (first and second keyboards) mounted on different housings, allowing each section to be independently operated. This segmentation enables more keys to be included while maintaining wearability, as each keyboard section can be positioned for optimal access by either hand.
Solution Approach 2:
The patent transitions from a single-dimensional keyboard layout to a three-dimensional configuration with keyboards positioned on opposite sides of the device. This allows the player to access more keys and controls by reaching around the device, effectively increasing the playable range without increasing the linear footprint.
2Device complexity
If a single keyboard is used on a keytar, then the device structure is simplified, but two-handed operation is impossible or impractical
Solution Approach 1:
The device is segmented into two independent keyboard sections that can be operated simultaneously by both hands. The first keyboard section is positioned for right-hand operation while the second keyboard section is positioned for left-hand operation, enabling true two-handed play.
Solution Approach 2:
The two keyboard sections are positioned asymmetrically on opposite sides of the device, with each keyboard oriented to be accessible by a specific hand. This asymmetric layout optimizes ergonomics for two-handed operation while maintaining a compact wearable form factor.
3Shape
If the keytar neck is made skinny to maintain wearable design, then the device remains comfortable to wear, but the neck controls are limited and cannot accommodate keys for left hand operation
Solution Approach 1:
Instead of expanding the neck thickness horizontally, the patent utilizes the vertical and depth dimensions by positioning the second keyboard section on the opposite side of the device. This allows full keyboard functionality for left-hand operation without compromising the slim wearable profile.
Solution Approach 2:
The opposite-side keyboard section serves multiple functions: it provides additional keys for left-hand operation, maintains the wearable slim profile, and enables independent control of both hands. This universal design solves multiple problems simultaneously.

AI summary
The present disclosure relates to double-ended keyboard devices and methods. In one embodiment, a device includes a first housing having a first keyboard section and control surface, with input keys arranged in a first direction and a second housing having a second keyboard section and control surface, with input keys arranged in a second direction. The device includes a joint securing the first housing and the second housing to provide rotation of the housings along an axis. The device also includes a control unit configured to detect input to housing and to generate output. The device includes an output interface coupled to the control unit. Processes are described including generating output based on detected input to the first and second keyboard sections and controlling output. Operations and devices configurations allow for a wearable control device that may be operated or played like an instrument.
