IEEE CanadaHumanitarian Design Competition Organizational Meeting Department of Electrical and Computer Engineering University of Waterloo Some slides taken from presentation on WE CARE solar suitcase by Hal Aronson & Laura Stachel
Objective of Competition • Provide venue for students to gain practical experience in improving or innovating on an existing design under some of the constraints and conditions they will face in industry. • Competition involves improving a “solar suitcase” for use in medical clinics in developing countries
WE CARE Solar Suitcase • A portable solar electric system that fits in a suitcase • Powers overhead LED lighting, charges walkie-talkies and cell phones, and includes LED headlamps that come with their own rechargeable batteries.
Energy Estimate: 40 watt PV Panel PV Watts x Sun Hours x 0.5 = Energy 40 watts x 5 hours x 0.5 = 100 watt-hrs
Example Use of 100 watt-hrs • Two 3-watt LEDs x 5 hours = 30 watt-hrs • Two cell phone charges = 10 watt-hrs • Eight AAA batteries = 10 watt-hrs • Laptop for 2 hours = 50 watt-hrs
Overview • WE CARE will make the details of their “solar suitcase” platform available as Open Source Hardware • Participants will be asked to study this system and to propose ideas that will improve it, extend it or innovate it. • It is mandatory to limit designs to parts of this platform • All designs will be “Open Source”, and will become part of the open platform
Potential Ideas • Simplification of the installation • Creation of a collection of direct current (12VDC) medical devices • Enabling the use of Li-Ion batteries • Enabling the use of electric handheld tool batteries • Optimizing the charge controller • Improving the system’s serviceability and cost • Improving the system’s enclosure • Innovating the connectors and cabling • Improving the effectiveness of recycling and sustainability
Logistics and Timeline • Teams submit project proposal (100-200 words) by Jan 14th describing what aspect of the platform they will be improving • Progress report due Feb 18th describing work done so far, timeline, design specs, etc. • Final report due April 1st, will be judged based on innovation, quality, completeness, practicality and complexity
Teams • Open to undergraduate and graduate students enrolled in a Canadian college or university. • Each team must be led by an IEEE student member • Other team members are not obligated to be members of the IEEE. • Teams are required to have a mentor (a professor from the institution where team is enrolled, or from industry) • Teams will have a minimum of 2 and a maximum of 4 members • No limit on the number of teams from a given institution • No entry fees
Prizes • Abstract of the winners’ work will be published in the IEEE Canadian Review magazine • First prize, CND $1000; second prize, CND $700; third prize, CND $300. • Top three teams will receive travel grants and complementary conference registration for the [2]Canadian Conference on Electrical and Computer Engineering (CCECE); at this conference, they will be asked to show their designs on the solar suitcase during a tutorial session. • Students will be rewarded at a ceremony that will take place during the CCECE in early May 2011 in Niagara Falls, Ontario.
Design Goals: Round Two • Maintain functionality • Reduce cost • Simplify installation • Provide suite of 12VDC appliances
Find the “best” PV Module • Manufacture • Friendship prices Or….. • Buy leftovers and used….
Optimize charge controller • Size: reduce Amperage (10A) • Type: PWM or MPPT? • Features: Displays • Price: trade degree of reliability if repair infrastructure in place?
Concentrate deployment • Better Data • Training • Maintenance/recycling infrastructure • Local assembly? Haiti; S Africa • Shipping
