2. The Background
Hand injuries account for 17% of all workday injuries.[1]
The most common amputation of the upper extremities is the loss of one or more fingers.[2]
Reasons for these amputations include cardiovascular disease, traumatic accidents, infection, tumors, nerve injury (trophic ulceration), and congenital anomalies.

3. Why? To help people and create freedom
To meet the needs of the disabled
We are engineers

4. Mission Statement
The purpose of this design project is to develop a coffee mug with attributes: such as, ease of use, cost efficiency, and durability by people with hand disabilities, specifically people with only one finger.

5. The MUG

6. Design Process Customer Needs Collection and Ranking User Friendly
We selected five first layer attributes that we felt the customer would want in a product
User Friendly
Able to use with only one finger
Durable
Simple Design
Safe

7. Design Process Customer Needs Collection and Ranking Inexpensive
Within these first layer attributes, we found second layer attributes that would be pleasing to a customer
User Friendly
Inexpensive
Simple to Use
Lock Tight Lid
Ambidextrous Design

8. Design Process Able to use with only one finger
No strain on joints or muscles
Single round handle for finger
Clamps to grab around the palm
Simple trigger to pull clamps

9. Design Process Durable Plastic with Insulation Trigger works well
Trigger is efficient
Simple Design
Solid Color
Lightweight
Flat Base

10. Design Process
Safe
Insulation
No sharp edges
Aerator
Grips

11. Design Process
Second Layer Attributes:
USER FRIENDLY

12. CAN USE WITH ONLY ONE FINGER

15. Design Process
SIMPLE DESIGN

16. Design Process Concept Generation based on Customer Needs Handle
Outside design
Material
Insulation

17. Design Process Concept Selection Good ideas and Bad ideas
Ex. Original trigger idea (“Josh’s Big Failure”)
What worked and what didn’t
Had to become one with our inner one-fingered persona

18. Design Process Concept Selection
The concept selection process consisted of the members of our group trying to determine what the most important attributes were to include in the final product

19. Design Process
We spent hours in deep thought

20. Design Process
We spent hours reading literature on other designs

21. Design Process
And after the long process of determining what to leave in, we came up with different combinations of the attributes that we believed were the best

22. Design Process Concept Selection
Adjustable, single-finger handle to fit all sizes
Vertical adjustability
Outside brace
Plastic, interior filling to prevent splashing
Insulated to retain heat but not burn the hand
Lock tight lid to prevent spillage

23. Design Process Prototype and Testing Used clay to prototype mug
Clay vs Ceramic vs Plastic vs Metal
Easy-to-use
Universal

24. Design Conclusion & Summary
Difficulties
Patents
Clay prototype
Confounding variables
Original design that is practical
Choosing the best design

25. Design Conclusion & Summary
What we learned from this project?
Prototype and solidworks model
Customer needs ranking (prioritizing)
Confounding variables
Importance of process
Originality
Innovation requires patience

26. Conclusion Best design
Allows physically disabled individuals to drink coffee with ease
No costly aspects of the mug
Fits all users
Safe
