Design Philosophy :

The very common process photosynthesis where plant prepares its food, is nothing but flow of electrons. And current is the same flow of electrons.

WOW we can generate current in our garden !

I was a kid when something like this stuck me hard. This made me believe that NATURE has in its own way. Similarly the very Human with their own avatars as a designer, researcher, scientist, engineer, artist and many more have there own way of working as well. These two are my main inspiration to develop any of the product or service or process.

Every object has own shadow, these are my Coloured Shadows of the works i have been doing.

Product Development Project - Buoycast

Product Development Project (PdP) course is focused at students of engineering, design, and business who are interested in product development. The study is defined on problem based learning. The project starts with a problem statement given by sponsored company who are searching for innovative collaboration with the next generation of product developers.

// Project PeriodSeptember 2014 - May 2015

ClientComnet -Research lab at Aalto University

TeamInter-disciplinary team of 11 students

The project started as an exploration for a low-cost variant for surface-to-surface communication on the water taking inspiration from message in bottle form of communication which dates back to 300 BC. The objective of Buoycast is to provide you connectivity even in the most extreme conditions.

The solutions provide the capability to drop messages, images, and tags on a self-sustainable router, which holds your message until it reaches its destination. It comes as an eco-friendly DIY kit, so you can build your own device. The modularity of the devices allows you the freedom to customize the final outcome. With Buoycast kit, you can have your own network wherever you want.

My main task here was to develop wind based systems apart from other project activities. Various wind turbine designs and alternator designs were considered and these were 3d printed, prototying and tested. More focused was given on ideating, prototyping and testing the concepts.

// Ideating and Initial concept

Based on the requirements like easily removable workpiece, extensive calibrating possibilities, compact design, to be able to print variable patterns. The initial concept was designed. After optimizing the concept the final detailed designed was modeled using PTC Creo.

All the parts were fabricated in the lab as per the modeled dimensions. The open source Arduino / reprap hardware and software were used for control and interface.

// Final Concept

- Using the cylindrical 3D printing method, some of the patterns printed were quite lightweight and surprisingly flexible with normal PLA.

- The printed pipes also turned out to be quite strong for their size.

- Reduced printing time (5 hours to 1,5 hours) compare to 3D Cartesian Printer.

Swach - Cellulose based Water Filters

Why // What

Water, one of the very basic needs for human survival is also one of the major challenges for human mortality in the developing world. Due to environmental crisis and population growth the scarcity of safe drinking water is a major demand to be addressed. There is a need for new water purifying methods and cellulose as an abundant and universal material is an ideal starting point to develop more efficient and more sustainable water filtration membrane technologies. Concepts proposed here are based upon my reflections and explorations with biomaterials.

Project PeriodJune 2015 - September 2015

ExhibitionWood and Bioenergy Fair, Jyväskylä.

Wood and Bioenergy Fair, Jyväskylä Finland.

This project was done as my summer course. CHEMARTS is a long-term strategic collaboration between two Aalto University schools, The School of Chemical Technology and The School of Arts, Design and Architecture. The main objective is to inspire students and researchers to explore biomaterial together and to create new concepts for the future use of cellulose and other biomaterial. I was very interested in these materials as these are the future materials which be building blocks for more sustainable technologies and products.

// Challenges // Process // Concepts

Pine tree became my inspiration as the Xylem tissue of pine helps in filtering the pathogens of the water. Based on this, my first concept filter demonstrates how a piece of pine could be used as a filter. For my second concept, I started working with the particular form of cellulose called NFC (Nano fibrillated cellulose). As cellulose is water absorbing (hydrophilic) and difficult to mold, my initial trials started by making thin films of NFC with additional compounds to improve the wet strength of membranes. With the help from the researchers at CHEM it was possible to make water resistant thin membranes using NFC and Chitosan (derivatives from sea shells). These membranes are surprisingly thin, very flexible and can filter the particles of diameter of 100nm. The second concept is to demonstrate how these membranes work and how these features can help to create simple products with water filters.

// Concepts

My experiences and the abundance of cellulose materials inspired me to continue the concept development. Bottle made with cellouse and derivatives – Plastic water bottles that we are using today take hundreds of years to degrade, causing land and water pollution. NFC could be used to produce flexible plastics and also tough composites, the future bottles made with NFC could be fully organic and biodegradable. The prototype bottle is made of NFC and other biodegradable materials to demonstrate the concept.

// Wearable filters

This concept is to demonstrate the embedding of NFC based membrane filters in future wearables. Idea of gloves with embedded NFC membrane is inspired by the natural human gesture of drinking water with hands.

Mono Rail - Loss Less

Loss Less is work by artist Salla Salin. She has approached Mechatronics department at Aalto University to build her concept for the exhibition. This project was taken by us and was done under course Mechatronics exercise.

Project PeriodFebruary 2015 - April 2015

TeamFour students

Exhibition: Lossless Galleria Huuto Uudenmaankatu, Helsinki

Galleria Huuto Uudenmaankatu, Helsinki

Objective of the project is to come up with a miniature indoor monorail system that will be hanging from gallery ceiling during a three week art exhibition. There will be motored wagon that carries around an external speaker in the exhibition room, creating “gapless surround sound” - effect inside the space. Space for the monorail system is approximately 5 x 5 m gallery room in Helsinki center, Punavuori. The system will be hanging from 3,5 meters height from concrete ceiling. The main challenge here was to consider the artist needs and time frame of 8 weeks to complete the project. The task for us was to consider the every requirement and design and build working prototype of the mono rail system. The mono rail was built successfully and has been exhibited in the month of march 2015.

Neeru - Extraction of water from Air

Project PeriodMarch 2011- May 2011

TeamTwo

AwardBest Mechanical Engineering project in JNTUH for 2011 batch.

This project was carried out as my Bachelor thesis. Neeru means Water in Telugu language which is spoken in South Indian state Andhra Pradesh. The idea of Extraction of water from air was developed to make a working prototype.

Drinking water which is one of the elixir for a human to survive is a challenging issue. Air is the only permanent and totally renewable source of water in the world. Well there is water around us all the time, but we just can’t see it. The air in our atmosphere contains a varying amount of water vapor, depending on the weather.

This air is part of the water cycle, an Earth process, water evaporates out of rivers, lakes and the ocean. It’s carried up into atmosphere, where it can collect into clouds. After the clouds reach the saturation point, water droplets take form, which we know as rain. This rain runs off the land and collects into bodies of water, where the whole process begins again.

The problem is the water cycle goes through dry periods. Because of this, why wait? Why not pull the water vapor right out of the air?

After the ideation of the concept the working principle of the machine was found, the methods that support the working principle were narrowed down and they were vapor compression refrigeration cycle and thermo electric cooling effect. The concept was modeled in detail using Catia and working prototypes were made to the scale and successfully tested.
