Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual tuning is used on traditional string instruments, then the instrument can produce musical notes, but the tuning process is time consuming and difficult

Engineering Contradiction:
Improvetuning speedVSAvoidtime required for tuning
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical tuning system with an electronic one. Instead of physically adjusting string tension with tuning pegs, the instrument uses electronic sensors to detect string position and a processor to control electronic actuators that adjust string position electronically, enabling automated and rapid tuning without manual intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the tuning parameter from mechanical string tension adjustment to electronic position control. The system uses sensors to detect string position and processes this information to control electronic actuators that move strings to precise positions, allowing for rapid and accurate tuning by changing positional parameters rather than mechanical tension.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If traditional string instruments are used, then the instrument structure is simple, but changing tuning in the middle of play is difficult to impossible

Engineering Contradiction:
Improvetuning flexibilityVSAvoidinstrument structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic tuning capability to the instrument. The electronic tuning system allows the string positions to be adjusted in real-time during performance through electronic control, transforming the static tuning of traditional instruments into a dynamic feature that can change instantly based on musical needs without requiring physical reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The electronic tuning system serves multiple functions: it enables instant tuning changes, allows for precise pitch control, and provides the ability to modify string positions during performance. This multi-functional electronic system consolidates what would otherwise require multiple separate mechanisms into a single integrated control system.

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

3Adaptability or versatility

If traditional string instruments are used, then the instrument is easy to operate, but limited notes are available

Engineering Contradiction:
Improvenote varietyVSAvoidoperational simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent expands the note variety by enabling continuous adjustment of string positions through electronic control. Instead of being limited to fixed string positions, the system can dynamically change string positions to produce a wide range of notes and pitches, effectively transforming the instrument from a fixed-pitch device to one with continuous pitch adjustment capability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The electronic system allows the instrument to dynamically adjust its pitch and note output in real-time. The sensors and processors work together to enable continuous modulation of string positions, creating a dynamic range of notes that can be accessed instantly during performance without requiring physical reconfiguration or complex operational procedures.

Inventive Principle:
Principle #15Dynamics

AI summary

A system and method for musical instruments with electronically tuned strings. The system comprises an instrument body designed to comprise a plurality of sensors configured to simulate strings on a music instrument. The sensors are designed to receive interaction and input from a user similarly to how strings behave on a string instrument, further comprising a processor and at least one output module. The system is implemented with a user control device configured to receive, store, and transmit at least one music profile, an output device, and a network configured to connect the user device and the output device to the instrument body. The sensors are configured to detect input factors when a user interacts with the sensors, wherein the input factors are transmitted to the processor. The processor then directs the output module to produce a number of musical notes based on the input factors and the music profile.
