The Client•NAU professor •Instructor of music education•Extensive experience teaching and performing•Member of Flagstaff Symphony
•She wants a custom violin bow attachment for a special student
Karin Hallberg
Fiona Carroll• Skilled 13 year old violinist
• Under Karin’s instruction
for 10 years
• Born with a cleft hand
that has only two digits
Secondary Client
Problem Definition
• Must fit hand with just two
digits
• Unlimited movement
• Maintain bow balance
• Advanced bow techniques
Create a bow attachment
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
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
Phase 4Prototyping and TestingDecember 2nd 2010 to February 24th 2011
Prototypinga) Create prototypesb) Present to Fiona for testingc) Improve and repeat
Deliverables: Final design as selected by Fiona
Phase 5Design Analysis February 24th to March 10th 2011
Review by technical advisorsDr. NelsonDr. Feigenbaum
a) Quantitative description of designb) Mechanical and physical propertiesc) Implement to final design
Deliverables: Analysis of design and reportBill of Materials
Phase 6
Construction of Final Product March 10th to April 7th 2011
Construct of final designa) Purchase materials for buildingb) Construct bow with attachment
Deliverables: Final PresentationFinished Product
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
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
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…
