Problem Definition

• Must fit hand with just two

digits

• Unlimited movement

• Maintain bow balance

• Advanced bow techniques

Create a bow attachment

Page 6: Fiona’s Bow

Project Overview•Many previous attempts have been made to facilitate bowing

•All previous models lack a custom feel

•Inconspicuous design•Light weight •Comfortable•Non-slip•Perfect fit

Phase 1Research and Project Idea Development October 5th to November 2nd 2010

Obtain pertinent informationa) About FionaHer conditionb) Violin bowTechniques

c) Previous attachment attempts

Deliverables: Comprehensive research Mold and x-ray analysis report

Phase 2Design Development based on Research November 2nd to November 18th 2010

Develop list of solutions to problema) Extensive brainstorming

b) Materials researchb) Narrow solutions to three main ideas

Deliverables: List of top 3 ideas with accompanying sketches and supporting reasons

Page 9: Fiona’s Bow

Phase 3Expert Review November 18th to December 2nd 2010

Take ideas to expertsa) Bow maker Jeff Robinsonb) Karin Hallberg

Deliverables: Final selected design based on review complete with detailed sketches

Current ResearchClassification of condition

Gain better understanding of range of motion and muscle strength

•Congenital •Very rare•Especially on just one hand•Both hands would be genetic

•Ectrodactyly type •Ectro- absence of •Dactyly- arrangement of digits

•Missing 4 central metacarpals and the 5th proximal phalanx

Page 14: Fiona’s Bow

Current ResearchViolin Bowing Techniques

Current configuration inhibits movement

Karen would like to see improvement with certain bow strokes:

•Depend on balance point•Spiccato-bow bounces on strings

•Certain Techniques require powerful strokes•Martele-power/hammer stroke

Page 15: Fiona’s Bow

ConclusionFiona needs a new bow attachment to replace her current model

The real challenge :

Although this project may seem easy at first…

Difficult to communicate with Fiona because she is shy…

The product must be to her express liking…
