ReFrame Design Review 2 - May 11, 2006 William Croisettier, Sarah Stein Greenberg, Gustavo Romero, Jin Tsubota

Big Idea | Build a Better Pump Frame “This is an important design challenge we have. Frames are crucial to every single user!” – Jim Taylor, IDE|m

Current User Complaints | Workarounds Too expensive Not adjustable –Treadles too short –Handle too far forward –Counterweights –Height of pump Unstable

The Customer Composite Character “Stavros” Farmer with one well on his property. Wife and children share pumping task. Bought pump but made frame out of bamboo by himself. Bamboo must be replaced frequently and isn’t very stable. Can’t afford the $16 cost of the existing frame. Doesn’t have a lot of tools and lives 8k from the village where there nearest carpenter has a shop. Etc.

Customer Choice Show Stavros making decision between frame options (including price points) w/ thought bubbles Chart of market share of each type Introducing… –The “MyanMyFrame!” »Cheap, customizable, stable.

Value Proposition of “the MyanMyFrame” Efficiency upgrade for people who are making their own frames Cheaper for people buying carpenter-made wood frames and IDE’s metal frames More customizable than any existing option More stable than any existing option

Design Concern | The DIY-OTS Continuum Available tools? Skills? Price sensitivity? Impression of durability? “Just Joints”Hybrid Materials Welded or Pre- Assembled Wood Do it Yourself (DIY)Off-the-Shelf (OTS)Some Assembly Required

Prototypes “Just Joints”Hybrid Materials Welded or Pre- Assembled Wood Do it Yourself (DIY)Off-the-Shelf (OTS)Some Assembly Required Jin’s drawings (And show physical protos)

Competitive Issues | Vulnerability Will (hopefully) replace local carpenters’ frames…effect on vendor/dealer relationships? IDE workers are welders, not carpenters…incentive alignment problem?

Organizational Plan Goal: To establish the process for using EA as a feeder source IDE’s product line by adding the MyanMyFrame. Implementation by September. No separate organizational structure Sarah goes to Myanmar this summer Capital for additional R&D from philanthropic sources if necessary (F&F)

Financial Plan Price ceilings (maximum points) that would compete with existing options: –Just Joints Solution < $8 –Hybrid (no carpenter required) $ –Off-the-shelf ultra durable $10 – 20 –[until we have the materials prices from Jim we can’t put together cost estimates based on materials ratios]

TBD Sensitivity Analyses Price of steel components (based on percentage of product that is steel) Price of wood, bamboo, rope, etc. Availability of wood, bamboo, rope, etc. Ability of IDE staff to provide “high touch” required for Just Joints? Other?

Next Steps TBD on Wed. / Thurs.
