POWER AT A COST

Portable

Pneumatic powered nailers compared to other categories are the most powerful nailers available and are sustainable as they are powered with compressed air or Nitrogen from bulky air compressors.

The main problem with traditional Pneumatic Nailers is

P O R TA B I L I T Y. This scenario is often seen where pneumatic nailers are used but it has its Pros and Cons too. The pros: The pneumatic nailer system is supplied with constant air supply, from an air compressor thus providing sustenance for a long time.

opportunity area

Expensive

The cons: Portability is heavily compromised, work space gets cluttered with hose pipe, not practical during tricky situations.

PROTOTYPING (STAGE 2) Basic thermocol mock-ups, MDF cutting, milling and shaping After the weight and balance test form exploration was done on thermocol and quick mock-ups were made. Also basic component arrangement and placement was done for size, shape and volume analysis The main idea was to bring out the whole model from one single piece of MDF, without a joint of any sort, thus making is very sturdy. Planning was a essential part as to which side to mill and drill first

RTA-70

CABIN RE-DESIGN


This project was done during my Internship at National Aerospace Laboratories (NAL), Bangalore. The main objective was to re-design the interior of a Civilian Aircraft RTA-70 (Regional Transport Aircraft, 70 Seater).

In my research I did a case study on the ATR-72, in Bengaluru International Airport, thanks to Kingfisher for letting this possible. And also studying the interiors of 70 seater airplanes e.g., Fokker 70, Embraer 170, Gulfstream I and others. The outcome was a refined and optimized interior, in terms of gaining space, comfort and aesthetics. A prototype of the same was also made, to validate the proposal. (Details are not shown due to confidentiality purposes).


Overhead Passenger Display and Controls

The first prototype would be a 70-seat plane. It is a family of aircraft that NAL is designing and will have three variants, a 70-seater, a 50-seater and an extended 90-seater version to be called RTA-90 with option of both Turbo prop and Turbo Fan as power source.

PROOF OF CONCEPT Quick actual size mock-ups made to figure out the mechanism

The idea was to come up with an innovative concept to merge the two different types of equipment of different purposes, into one reliable product. According to the scenario for those who have problems with movement and walking. The first challenge was to figure out the mechanism for a height adjustable walker and at the same time to have a nylon thread inside to be used as a puller for the item picker.

Lower body – the lower part of the walker also made with aluminum, houses the picker, and has holes for height adjustments. Pulley & lock – used to coil up extra nylon thread and lock it after height adjustment.

Item picker

Fixed pivot – points where it acts like a fulcrum or joint Nylon thread – used to pull the picker. Item picker – used to grab objects of interests Handle – plastic handle for grip and usage Spring – used to bring back the picker after nylon thread is in resting position.

When trying to grab When the trigger is pulled back, it pulls the nylon thread back, as its fixed to the pivot. The nylon thread is pulled back over the fixed pivot in the lower body, which in turn pulls the picker. The picker as shown in the diagram is fixed to a pivot and gets pulled up grabbing a required item.

SUSTAINABLE SEGREGATION BOSCH-NID DESIGN COMPETITION 2012


PROBLEM STATEMENT

Issues with Drainage systems: Clogged drains due to lot of garbage results in flood during rainy seasons Stagnant Drainage gives rise various diseases Also results in increase in no. of mosquitoes Making the surrounding area prone to diseases like Malaria and Dengue Also bad odor makes the environment unhealthy


SCOPE AND OPPORTUNITY Narrowing down scope of research: Including big cities, the suffering and pain caused by open drainage systems in small cities, towns and suburbs cannot be ignored.

Main reasons for choked drainage: The pie chart here shows a typical garbage composition, where plastic makes a 16% share, which is non-biodegradable, a serious agent for water clogging in our drainage system including open drains.

SMALL CITIES

OPEN DRAINS

DRAINAGE SYSTEMS

RIVER

BIG CITIES

CLOSED OR UNDERGROUND


THE CONCEPT

THE SEPARATOR

GARBAGE SEGREGATION Garbage separation through sustainable measures using Bamboo.

Why Bamboo ? Bamboo is one of the world’s most sustainable resources. Bamboo is a light material due to its circular form and the empty cavities which make it float on water, making it a ideal material for the concept. Besides being cheap, it is easy to store and transport. Because of its physical characteristics, bamboo is a very strong material and flexible at the same time.

The main shaft acts as the main body, four holes are drilled in diagonal pairs.


Split bamboo sticks inserted in the main shaft through drill holes to be fixed tightly

Loose-Lock Mechanism: Extra smaller sticks at the edges of the device almost toughing the Supporting-poles are given to prevent the whole thing from rolling over and spilling the collected garbage in the drain water during high water currents.

240 cms

42 cms


THE DOCKING

The device Separator can be easily installed with manual labor, using ropes of just bare hands. Once installed it remains within the support poles also made of bamboo. The Support Poles keeps it in its place at the same time lets is rise or depress according to water level. Also the device restricts itself from getting rolled over due to water pressure with its Loose-Lock Mechanism.


DOCKING

Jute ropes can be used for installation or removal of device

Support-Poles for sustaining the device.


Garbage Management:

Garbage getting separated and accumulated to be easily cleaned and picked up by Laborers


TO A BETTER CLEAN AND SUSTAINABLE FUTURE: No solution can stand-alone solve any problems without proper management and man power. Similarly in this proposed sustainable concept, rather a concept approach acting as a major aid to the laborers is required to check and clean the collected garbage in the Separator at intervals

If thoroughly followed, issues like floods, diseases and bad health should be just a matter of time to fade away for a more greener and well managed town or city.

INSTITUTIONAL CATERING A SYSTEMS STUDY


In this project I have looked in the primary aspects of food, health, people’s demand and satisfaction in catering services, provided in institutes, as a system. Here I tried to find the factors and their relations, which deals with providing the end user their satisfaction and value for money. Finally coming out with critical problem areas, analyzing them, and putting them together graphically to form a systems model. Then finding loop holes in the system model, and coming up with solutions for the same. Here the co-relations of various factors and their relations are shown, along with the gap which needs to be fulfilled, where design opportunities arise. Here inner circle indicate the students and the enclosing outer circle the caterers, showing their service and other attributes and factors, in a relation affecting each other.

I found that the main problem lies in a constructive communication between the students and the caterers. Where in one hand the caterers think they are providing the best, and on the other hand there are the stakeholders, who are not satisfied with it.

Student Committee

My analysis shows that change in the caterers attitude towards production can only be brought by proper communication through some interacting medium. An idea to plant a solution to the system and wait for its results.

CONCEPT SOLUTION

After thorough research this was one of the solution, to introduce a tablet or computer application where the caterers can easily take a feedback of their services and future menu selection.

SAC + ADMIN + CATERER

This idea is a modification of a previous idea for an App, where huge data collection, analysis and interaction would be possible. As in my research it was seen that problems regarding ‘Catering Services’ don’t get proper hearing and there is a huge communication gap. Thus the idea was to incorporate a platform to our existing NID Portal, an intra-net service, where the main bodies in this system, which are STUDENT, SAC (STUDENT ACTIVITY COUNCIL), ADMIN and CATERERS can interact and communicate. So that if any query comes up from the students regarding Catering Services can be put up in the platform, and can be seen by all these main bodies, including College Admins.

WEBSITE REVAMP

REVAMPING THE INDIAN RAILWAY WEBSITE


This is how the website presently looks


This is a self initiated project where we have tried to revamp the Indian Railways Passenger Reservation Enquiry website. http://www.indianrail.gov.in/ Like many others we have often felt that the site needed a better interface along with better looks. After all it is an Indian Govt. website & people use it all the time. We have tried to keep as much originality as possible & have not done anything too lateral & drastic. The color palette is close enough & We have kept most of the information available on the site with space for advertisements, news and other such stuff.

The main design changes are: • Giving the PNR STATUS a complete new space on the website instead of a tab. • Making a tab for HOME as the website did not have a proper HOME page. • Making the search more flexible and instant thus decreasing the cognitive load & mental fatigue.
