Team Vision for Problem Definition Phase

In this phase, our team mainly planned to finalize our design review phase I presentation for our customer. We also created a checklist of items to have defined and completed in this phase: Customer Requirements, Engineering Requirements, House of Quality, Use Scenarios, Risk Matrix, Problem Statement, Deliverables/Goals, Stakeholders, Timeline (High Level and Low Level), Project Constraints, Group Norms and Values. We also planned to attend another team's design review and have a pre-meeting with our customer before our design review. Our team completed all of the mentioned tasks.

Project Summary

Many standard musical instruments, such as guitars and pianos, have stood the test of time due to their ease of use and expressive nature. However, in the advent of new technology, not many changes have been made to improve upon some of the limitations that plague their designs. Often times they offer little variability in timbre and have no way to provide a visual performance.The Martone is a new musical instrument that incorporates reactive lighting effects into sound generation to provide a unique musical experience. It uses touchscreen technology combined with the aesthetic feel of guitar strings to produce each note and features adjustable legs to promote a variety of play-styles. In addition, each string can be easily programmed to produce different sounds or to control sound qualities produced by other strings, all from a mobile app.

In its present state, the Martone lacks programmability and reactive lighting and is limited to only four functioning strings. Its touchscreen also needs improvement as it does not reliably react to user touch as intended. Physical elements such as the legs and body shape require development as well. The major goals for this project are to add reactive lighting and improve the responsiveness of the touchscreen. The Martone body will be altered to fit all components in a more efficient way while respecting the ergonomics and manufacturability of the design. Musical effects and the mobile app are not expected to be addressed by the MSD team. The final state is expected to be a functioning prototype that qualifies as a potentially marketable musical instrument.
