Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic musical instruments lack innovation and typically mimic acoustic instruments, with the Theremin being the only true electronic instrument but limited in sound and functionality, failing to gain respect as a musical instrument.
Innovation Solution
A platter-based electronic musical instrument that rotates to shift sound sample frequencies, comprising a platter, rotational position sensor, buffer, and processor, allowing users to select and manipulate sound samples by rotating the platter to change frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic musical instruments mimic acoustic instruments, then they are familiar and easy to use, but they lack innovation and true electronic capabilities
Solution Approach 1:
The patent replaces traditional mechanical acoustic instrument mechanisms with electronic signal processing. Instead of physical strings, reeds, or air columns, the invention uses digital audio samples processed through electronic frequency manipulation controlled by platter rotation, creating a truly electronic instrument that doesn't mimic acoustic mechanisms
Solution Approach 2:
The invention dynamically changes the frequency parameter of audio samples in real-time based on platter rotation position. The processor modifies pitch and tonal characteristics electronically, allowing continuous parameter variation that creates new expressive possibilities beyond traditional acoustic instruments
2Adaptability or versatility
If the Theremin is used as an electronic musical instrument, then it is a true electronic instrument, but its sound is limited and output is constant
Solution Approach 1:
The patent loads multiple different audio samples into memory, allowing a single instrument to produce diverse sounds including but not limited to vocal samples, instrument samples, and synthesized sounds. This multi-functionality replaces the Theremin's limited oscillator-based sound generation
Solution Approach 2:
The invention introduces dynamic control through platter rotation, where the rotational position continuously modulates frequency parameters. This creates expressive dynamic ranges and pitch variations that overcome the Theremin's constant output limitation, allowing smooth transitions and nuanced performance control
3Adaptability or versatility
If a platter is used to control frequency, then frequency manipulation becomes dynamic and expressive, but the device complexity increases
Solution Approach 1:
The patent introduces a platter with rotational position sensor as an intermediary control device between the performer and the digital signal processing system. This mechanical interface translates physical rotation into electronic control signals, providing intuitive frequency manipulation while the processor handles the complex frequency shifting algorithms
Solution Approach 2:
The invention replaces complex manual frequency control interfaces with an automated sensor-based system. The rotational position sensor continuously provides position data to the processor, which automatically calculates and applies the appropriate frequency shifts, eliminating the need for manual tuning or complex control mechanisms

AI summary
An electronic musical instrument includes a platter, rotational position sensor, and a processor. The platter can be rotated about a center point by a user. The rotational position sensor senses rotation of the platter and provides a position signal indicative of the sense rotation of the platter. The buffer stores a sound sample. The processor receives the position signal from the rotational position sensor, determines a rotational position of the platter as a function of the position signal, retrieves a sound sample from a buffer, shifts a frequency of the sound sample as a function of the determined rotational position of the platter, and renders the frequency-shifted sound sample. The instrument may also include user inputs for selecting octaves per rotation and scale divisions within each octave which further define the frequency shift applied by the processor as a function of the determined rotational position of the platter.
