Project Overview

Mission Statement

Design and construct all mechanical and structural aspects of a thermoelectric charcoal cook stove.

The stove will utilize forced draft powered by thermo-electrics to significantly increase thermal efficiency and reduce emissions over a traditional Haitian stove.

Needs

Customer Need # Importance Description Comments/Status

CN1 1 Quick to start Better than existingCN2 1 Reaches boiling rapidly Better than existingCN3 2 Able to reduce thermal power to simmer CN5 1 Affordable for a typical Haitian vendor to purchase CN6 1 Affordable to operate CN7 2 Easy to operate CN8 2 Intuitive to operate CN9 3 Long life

CN10 2 Durability to withstand typical use, transport, and exposure CN11 2 Repairable - parts swappable and with available skillsets and resources CN12 2 Easy to transport CN13 1 Uses forced air CN14 1 Safe to operate both indoor and outdoor CN15 2 Uses significant less fuel CN16 1 Emits significant less harmful emissions CN17 2 Meet or improve traditional cooking methods CN18 1 Stove can be manufactured using available resources CN19 2 Safe and easy removal of unburned charcoal CN20 2 Uses little pumping power for desired airflow <1 watt pumping power

CN21 2 Sustains boil as long as current stoves

Cust. Need #: enables cross-referencing (traceability) with specificationsImportance: Sample scale (1=must have, 2=nice to have, 3=preference only), or see Ulrich exhibit 4-8.Description: organize as primary and secondary needs (hierarchy) -- Ulrich exhibit 4.8Comment/Status: allows tracking of questions, proposed changes, etc; indicate if you are meeting the need ("met") or not ("not met")
