Solution Overview

Problem

Traditional pianos typically produce a single C4 pitch, making it unsuitable for multiple players to play or learn simultaneously, as they cannot share the same octaves without interfering with each other's sound.

Innovation Solution

A piano system with a keyboard, sensors, and a processor that divides the keyboard into groups, generates distinct sound control signals based on sensor data, and displays visual information, allowing multiple players to play different timbres on the same piano without interference by using a muting unit to prevent string interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional piano produces a single C4 pitch for each key, then the piano maintains simple structure and operation, but it becomes unsuitable for multiple players to play or learn simultaneously

Engineering Contradiction:
Improvemultiplayer capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The keyboard is divided into multiple sensor groups (first group and second group), where each group can be independently controlled to produce different timbres. This segmentation allows multiple players to play simultaneously on the same piano without interference, as each player's keys are processed separately through dedicated sensors and sound control signals.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A single piano system is designed to serve multiple functions: it can accommodate multiple players simultaneously, provide different timbres for different key groups, and support both solo and multiplayer modes. The system achieves this universality through configurable sensor groups that can be assigned to different players and instrument types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple players play on the same piano without interference, then multiplayer capability is enabled, but additional sensors and control systems are required

Engineering Contradiction:
Improvemultiplayer capabilityVSAvoidsensor and control system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor system is divided into multiple independent groups (first sensor group, second sensor group), where each group monitors specific key ranges. This segmentation allows the system to process multiple players' inputs separately while using a unified control architecture, reducing the overall complexity compared to having completely independent systems for each player.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple sensor groups and their corresponding control signals are merged into a single integrated system that processes all inputs through a common processor and output mechanism. This consolidation allows the piano to handle multiple players simultaneously while maintaining a unified structure rather than requiring separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If distinct timbres are generated for different player groups, then sound differentiation is achieved, but additional sound control signals and processing are required

Engineering Contradiction:
Improvetimbre differentiationVSAvoidsound control signal complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different timbres are assigned to different sensor groups based on their specific functions. The first sensor group generates sound control signals for one timbre while the second sensor group generates signals for another timbre. This local differentiation allows each key group to have optimized sound characteristics suitable for its intended use while maintaining overall system coherence.

Inventive Principle:
Principle #3Local quality

4Loss of information

If visual information is displayed for sensor signals, then player feedback is improved, but screen and processing components are added

Engineering Contradiction:
Improveplayer feedbackVSAvoidvisual display system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Visual information is generated based on sensor signals and displayed on a screen to provide real-time feedback to players. This feedback mechanism allows players to see which keys are being pressed and how the system is responding, improving their ability to learn and perform. The visual display is integrated into the existing system architecture rather than being a completely separate addition.

Inventive Principle:
Principle #23Feedback
