GIAN Summer School on ....Open Inclusive Innovation 2019 |

| Details |
"The objective of the Summer School was to define and address the unmet social problems through viable and effective solutions. GIAN invited students from various polytechnics and ITIs from Gujarat, Maharashtra, and Goa. The sessions included topics like mindsets & methods of Human Centre Design, tools to generate empathy with user, designing prototype and iterative testing and redesign etc., among others. Additionally, students were asked to present their reports based on their field visits. Other activities included mind mapping and canvasing their research ideas for which they received constructive feedback from Prof. Sanjay Sarma, former Dean, and Professor of Mechanical Engineering, MIT, Boston, USA. Since, this was organised in collaboration with SRISTI Summer School, most of the classes were common.
During the application process, each of the students submitted a one-page application which also included details on the unmet social needs of their village, town or city. Finally, 26 students from Gujarat, Maharashtra, Goa, and Nagaland attended the GIAN summer school. The projects on which students worked were:
1. Mahua Oil Expeller
Keyur Undaviya, Utsav Malam, Keyur
Kanjareeya & Pallav Maru
Oil extracted from Mahua seeds is used in cooking. The waste from the extraction process is generally used as manure. Tribal communities either travel far to get the oil extracted or use traditional methods, which involved crushing the seeds by placing them between two wooden logs. Three people were needed for this tedious process, which also resulted in oil wastage.
In the absence of electricity in many tribal areas, one needs manual oil expellers. During the team visit, it was learned that the onset of flowering happens only after six to eight years after the tree is planted. From one kg of seeds, an average of 400-450 grams of oil can be extracted. It takes approximately 15 mins to extract complete oil from 15 kg of seeds. The waste generated during the extraction process is sold to farmers as manure at Rs. 2-4 per kg.
The new device is made up of wood and has a stainless screw in the middle. In the new method, oil is extracted by simply rotating the screw handle but much more improvement remains to be done.
After a few trials, it was felt that the new model required further tweaks in design. The students are currently seeking mentoring from industry experts in the Rajkot industrial cluster.
2. Mahua Nut Cracker
Pritish Pandya, Dhyey Pandya, Bhavik Modha & Vikas Meghnathi
Introduction
Tribal communities use mahua seeds to produce oil for cooking. First, the ripened fruit is pressed to remove the seed. Next, the brown, hard, shiny seeds are hammered with stones to crack them open. The process is hazardous and inefficient The kernel is, cracked by peeling off the brownish shell, and then dried and ground using a machine or a contraption, which is available locally.
The students visited the communities and designed a single-hole nut-sizing device allowing the operator to place the nut in such a way that it cuts into two parts. The design needs further improvement because the purpose is to crack the outer shell and take the kernel out.
3. Brine Water Detection Device Shivani Lal, Meena Kokare, Sakshi Thappa, Neha Gumal, Ketan Jailkar & Omshree Dalvi
This technique is used to detect the levels of salt in the groundwater. A community of salt farmers, known as Agariyas, found it difficult to detect brine water effectively. The students met the locals and brainstormed on the issue as tohow to efficiently and effectively detect brine groundwater.
Saltwater or brine water is a good conductor of electricity and, therefore, offers relatively less resistance, ultimately reducing the overall time taken to complete the circuit.
Ground resistance depends on grounding electrode selection, soil resistivity, soil contact, and other factors. The 62% method (aka Simplified Fall of Potential Test) is one way of measuring the ground resistance at the site.
The basic setup for a resistivity survey involves using a resistivity meter and four electrodes.
The device, though, needs further development and field trials.
