People have a tendency to keep footpaths clean, but litter the sides. Almost any object — lamp posts, traffic cordons, abandoned construction material — can be used as a dustbin, reveals a research project through pictures.
The findings will be showcased at the annual Design and Degree Show (DDS), organised by IIT Bombay’s Industrial Design Centre (IDC). The event will be held at the Powai campus from June 13 to 17.
“It seems people want to keep the sidewalk somewhat clean, so they throw stuff on the side, where the drain usually is. The findings show that drains, holes, missing bricks in pavements and ill-maintained areas attract spitting and litter. Unexpectedly, people litter in clean areas like malls, too, but the area is constantly cleaned, so it is not very noticeable,” said Sylvan Lobo, who has done a photo study of garbage and littering behaviour in Mumbai.
Going a step further, Paul Anthony, who has worked on solid waste management solutions for Mumbai, created ‘gobbler’ for solid waste disposal and segregation. “The backbone of Mumbai’s waste system is its waste handlers and often unrecognised ragpickers. Part of the project deals with employment of this community which sorts and recycles waste. A metal structure houses a portable mechanical shredder that shreds plastic, metal and paper — the dry waste items. At this nascent stage, it is hand cranked, but there are possibilities of modifying the structural form and nature of the shredder to make it motor powered,” he said.
Around 190 design projects from 56 students will be featured at the show.
Trivikram Annamalai has created a working prototype of a low-cost vein detector. “The thought of an getting an injection can be traumatising. Also, for certain patients, it’s difficult to spot the vein, leading to multiple needle insertions. A vein detector costs Rs 2.5 lakh abroad, and our survey shows that just one hospital in the city has it. My product, which is in user-testing phase in some hospitals, costs around Rs 1,500. This will enable small hospitals and clinics to purchase the device,” said Annamalai.
Gourab Saha has developed a system to aid psychotherapy of depressed college students. The final design proposal features a multi-sensory headset, whose functionality is dependent on a “reinforcement learning app”, linking the user to his or her therapist and support network for daily monitoring of the user’s progress.
A car accident detection system using mobile phone, growth monitoring device for infants and water purifier for floods were other innovations.
The art, craft and culture segment features an animated short fil‘ ‘Being Girl’ that aims to create awareness about gender discrimination, “In Search of Democracy’ explores the idea of democracy and governance in the backdrop of 2014 Lok Sabha elections.
