DESIGN CHALLENGE: POWER SUPPLY
IEC 309 CONNECTOR FOR POWER DISTRIBUTION UNIT: Nuwakot District Hospital was heavily damaged in the earthquake, and with many of its buildings destroyed a large number of its services are being run out of tents, such as the one visible in the video. In order that these tents have the lights and electrical power necessary to run hospital equipment, cables from the mains and backup power supplies are run directly to each tent. The power distribution unit acts as a fuse box, and enables everyday equipment to be connected to the power source. However, the plastic connector enabling the IEC 309 power cable to be connected to the unit has broken, rendering the unit useless.
The plastic at the connection point has cracked, meaning the power cable cannot be screwed into the fitting. A new IEC 309 connection fitting needs to be modelled and 3D printed.
