Practice Apparatus Using Colored Light Beams for Key Position Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beginners struggle to learn piano as they cannot easily associate music scores with keyboard keys without a piano teacher, and existing training methods are either too complex or economically restrictive.
Innovation Solution
A practice apparatus comprising a light source device emitting colored light beams to keyboard keys, fluorescent paper pieces on fingers, and a main device controlling the light beam colors and timing based on music information, allowing players to practice key positions without a keyboard instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a performance training apparatus is attached to a keyboard instrument to teach key depression positions, then key depression positions can be taught effectively, but the apparatus cannot function without a keyboard instrument
Solution Approach 1:
The patent uses a keyboard-shaped board with keys that can be pressed, which is a copy or simulation of an actual keyboard instrument. This allows the training apparatus to function independently without requiring a real keyboard instrument, while still providing the same training functionality for key depression positions
Solution Approach 2:
The training apparatus is divided into separate functional components: the keyboard-shaped board for physical practice, the light source device for visual guidance, and the main device for control and music information processing. This segmentation allows each component to function independently and enables the apparatus to operate without being attached to an external keyboard instrument
2Measurement precision
If colored light beams are emitted to keyboard keys to indicate correct key depression positions, then practice accuracy is improved, but the complexity of the light source device increases
Solution Approach 1:
The light source device emits light beams in different colors (such as green for correct key depression, red for incorrect) to provide immediate visual feedback to the user. This color-coding system simplifies the interface and improves accuracy without requiring complex detection mechanisms, as the color information is directly conveyed to the user
Solution Approach 2:
The light beams act as an intermediary between the keyboard keys and the user's eyes, providing visual information about correct key depression positions. This optical intermediary simplifies the system compared to using mechanical sensors or electronic displays, as light can be emitted directly from the keyboard structure itself

AI summary
A practice apparatus includes a light source device that emits light beams in different colors to keystroke positions on a keyboard or a keystroke object with keystroke positions that imitates a keyboard, fluorescent paper pieces that are respectively attached to the fingers of a player and have different colors for different fingers, and a main device that has a storage unit for storing therein music information on music and a transmitting unit for transmitting, to the light source device, a signal relating to the colors of the light beams, which depend on the colors of the fluorescent paper pieces attached to the fingers of the player, and the timing of emitting the light beams, based on the music information stored in the storage unit.
