Playano : Concept development project of a wireless and energy-harvesting piano keyboard (English)
Abstract [en]

This report contains a product and concept development project carried out by André Hedh as a Bachelor Thesis at Karlstad University’s faculty of Health, Nature and Engineering Science in the Innovation and Design Engineering Programme.

The project was carried out for design agency People People with Per Brickstad as task manager.

Prior to this project, People People had, through its subsidiary - People Products, developed The Transparent Speaker. Their wish was to develop more products for music lovers and musicians.

The product developed in this project was a keyboard, which was one of three products in a family that aimed to make it easier, more fun and more social to learn and play the piano.

The keyboard was designed to maintain the genuine feeling of a classic acoustic piano, but with modern technology for wireless communication.

The work dealt with studies and investigations in what distinguish the feel of the grand piano action, plus creativity and engineering methods to simulate this feel.

The project also aimed to incorporate an Energy-Harvesting system into the piano’s mechanism, to eliminate external power supply.

The kinetic energy from the keystroke was converted to electricity and used to set up a wireless connection over Bluetooth Low Energy with an external application that could translate MIDI data into sound.

A proof-of-concept was developed through a full-scale prototype of the key mechanism, containing a conceptual solution for the mechanism including all electronics and key features of the final product’s design. 

Abstract [sv]

Denna rapport innehåller ett produkt- och konceptutvecklingsprojekt genomfört av André Hedh. Projektet utfördes som examensarbete vid fakulteten för hälsa-, natur- och teknikvetenskap på Karlstads universitet i högskoleingenjörsprogrammet i innovationsteknik och design.

Uppdragsgivare för projektet var Per Brickstad på designbyrån People People i Stockholm.

Tidigare hade People People, under sitt dotterbolag – People products, utvecklat The Transparent Speaker och ville efter det ta ytterligare ett kliv in på musikmarknaden. Produkten som utvecklats i detta projekt var en klaviatur. Klaviaturen var en del av tre i en produktfamilj med målet är att göra det lättare, roligare och mer socialt att skapa musik genom att spela piano.

Projektets mål var att utveckla en klaviatur som fångade den genuina känslan från ett klassiskt akustiskt piano och som inkorporerar modern teknik för trådlös kommunikation. Arbetet behandlade studier och laborationer i vad som utmärker anslagskänslan hos en klassisk flygelmekanism. Kreativitets- och ingenjörsmässiga metoder användes för att simulera denna känsla.

Projektet behandlade även energialstrande system som förenades med klaviaturens mekanism med mål att eliminera extern strömtillförsel. Den kinetiska energin från tangentanslaget omvandlades till elektricitet som drev den trådlösa kommunikationen innehållande MIDI-information över Bluetooth Low Energy till applikation för ljudåtergivning.

En fullskalig prototyp över tangentmekanismen utvecklades som ett ”proof-of-concept”, innehållande en konceptuell lösning för mekanism, all elektronik samt produktens övergripande formspråk.
