Water Filter Bottle for CRPF Jawans

This project is aimed at designing a pump based water filter bottle for CRPF Jawans which is lightweight, durable, soundproof, easy to carry, use, maintain and has a capacity of storing 1 to 2 liters of water.

CRPF Jawan will keep the bottle inside pocket of the bag. When he reaches the contaminated water source, he takes out the bottle from the bag. He opens the base cap, takes out the filter which is attached to the pump with the help of pipe and throws it into the water source. He then hand cranks to pump in clean water into the water bottle. After pumping, he takes out the filter from a water source, wind up the pipe and put it back into base cap. He snaps the base cap to the bottle. He, then opens the drinking cap and drinks potable water from the bottle.

Features:

1) The device has a built-in pumping system for ease of drawing and filtering water.

2) There is a storage provision for the filtered water after pumping.

3) Use of HDPE makes the bottle durable as HDPE is safest form of plastic to be used as it is very hard wearing, does not breakdown under exposure to extreme weather conditions.

4) The filter housing is integrated with the bottle.

5) Hand cranking is preferable and more advantageous to suction for obtaining filtered water.

Water Cart

A group of women, colorful dupattas aflutter, beautifully silhouetted against a rising/setting sun,  gracefully balancing two to three pots atop their heads —an easily identifiable, immediately recognizable image of rural India.  Reality, however, isn’t as picturesque. Village women already burdened by domestic and farming activities, are spending longer and longer number of hours to get water from the increasingly parched wells of the region. Uneven terrains and larger loads are putting a strain on their necks(read here and here, how research is debunking the mythical benefits of load bearing), their health and their time especially during the hot summer months.

A product is required that can carry larger loads of water— in one go— across our uneven, rural terrains, with as little physical exertion as possible. This is where we roll in our Water Cart:

The Design Innovation Center alongwith a group of IIT Alumni are designing a water cart that can carry upto 30 kgs of water (the daily drinking water requirement of 10-15 people) along rural pathways. As always, our focus will be on creating a product that is easily manufactured locally, with locally sourced materials. And our process, will involve testing in actual conditions throughout the design process. To this end, we are now eagerly waiting to test our first prototype in the wadis of Shahapur Taluka— to determine our next round of modifications. Watch this space to see how our design process unfolds.

Helikite

Concept and Applications:

Helikite is a balloon-kite hybrid aerial platform which combines the properties and thus advantages of both a balloon and a kite. A balloon is affixed with a kite at the bottom and this assembly is secured to the ground using a tether. To counter the phenomenon of lowering of height with increase in wind speed which is a major problem with tethered simple balloons and even aerodynamic balloons, better known as Aerostats, the kite part of the Helikite system, helps by providing a surface area so as to produce dynamic lift which goes on increasing with the increase in wind speed. This lift tries to push the system upwards thus, utilizing the wind to gain height instead of decreasing it. This is how the dynamic plus static lift and tether combination helps the helikite in maintaining the altitude of deployment. A twin barrel winch is used to secure the tether to the ground. This system on a whole (balloon+kite+tether), is lighter than air. A keel is attached perpendicular to the bottom surface of the kite. This keel aids in aligning the entire system in the wind direction.

Helikite, on account of its dynamic lift, is a compact and relatively stable aerial platform which can find applications in the fields of agriculture, civilian surveillance, defense surveillance and weather analysis.

In agricultural applications, mounting visual and infrared cameras on the Helikite, can help detect water stress on the crops at an early stage. Water stress is the deficiency of water in the crops either due to improper irrigation or over perspiration. This leads to subtle and gradual increase in crop temperature just like increase in temperature in us humans just before and during a disease. This technique makes the farmer aware of any impending crop health issues quite early and also assists in irrigation planning.

Helikite can also be used in cases of natural disasters to get an overview of the area under distress. Night lighting and Advertisement are also some of the domains where Helikites can find applications in.

Current Status:

            A small scale mock model of the system was made out of a gym ball and a specially designed and  stitched kite to explore and understand various balloon- kite securing methods. An appropriate method was finalized to be adopted for the first 1:1 scale prototype. The prototype currently is in the final stages of fabrication. Balloon, Kite, Tether and Winch are ready to be used. Kite framework is being worked out as of now. This prototype has been designed to carry a payload of 3 kg.

Seat Prop for Police Stick

Our Redesigned Police lathis are ready to report for duty!. The  Design Innovation Center has taken forward this seed of an idea for supporting a policeman’s various postures during long hours of duty- all the way to production stage. The design was a simple rubber moulded attachment that can provide a soft “seating” for the policemen to rest their elbows or lean upon. Led by Prof. Chakravarthy, this has meant the project has been though many levels of prototyping, user survey, improvement and refinement.

Smokeless Biomass Cooking Stove – Shrot

Shrot (श्रोत ):

  • Over 4,000,000 people die prematurely from illness attributable to the household air pollution caused by cooking with solid fuels.
  • More than 50% of premature deaths due to pneumonia among children under 5 are caused by the particulate matter (soot) inhaled from household air pollution.
  • Black carbon (sooty particles) and methane emitted by inefficient stove combustion are powerful climate change pollutant

A statistic is not required to understand the discomfort of thick sooty smoke stinging your eyes and invading your lungs every single time you need to cook a meal. Yet people who depend on these chulhas have shown a historic reluctance to adopt other methods of cooking.

The Shrot, is a cost effective solution. It allows users to continue with their traditional fuel sources —wood, cow dung, discarded coconut shells, agricultural waste—while cutting down the toxic gases and soot produced by more than 50%. And with every cooking cycle it converts the solid fuels to saleable high calorific values charcoal—giving a profit incentive to the BPL and low income homes that typically use the traditional Chulha.

Palkhi for Vaishnodevi

The Vaishno Devi Palkhi has been redesigned for improving the conditions in which Palkhi bearers make a livelihood. The heavy Palkhi rest upon their shoulders causing injury and long term muscle damage to the Palkhi bearers. After studying these conditions and also understanding the Palkhi bearers’ requirements (they didn’t wish for a design that would demand too many changes in their ways), the Palkhi was redesigned in stainless steel to be 30 kgs lighter than the current Palkhi. Ergonomic experts in the field made small changes in the seating angles. And, the Palkhi was designed for easy replication by local vendors thus addressing local livelihood and sustainability issues.

Ajanta Palkhi

The Ajanta caves are a complex of 30 rock–cut Buddhist Caves containing paintings and sculptures from Indian and Buddhist religious art. Thousands of pilgrims, including the elderly and physically challenged, visit this site every year. The rough terrain, steep inclinations and large number of steps are arduous to walk through, thus making a palanquin system the only other feasible option. The existing design, made from wood or bamboo, carried by four male porters—is not comfortable for the user or the bearer. The Palki Design of this project focuses on these ergonomic issues while ensuring safe navigation through the narrow, winding passageways.

Selective Drumstick Cutter

Drumsticks, may occupy a place on in Indian meals but are unlikely to be found in design thinking process. Incidentally, India is the largest producer of drumstick. The harvesting of drumsticks is a very delicate process and a huge percentage of food waste can be eliminated if the tools used for harvesting are better designed.

This drumstick plucker carefully picks the ripe drumsticks while leaving the immature pods on the tree. The plucker has been designed considering ergonomics and affordability.

Heritage Lighting

Lighting—that can enhance Heritage temples and forts by night – is currently done in a fairly insensitive manner. Nails are driven into century old stone walls, irreparably damaging the sculptures, murals and inscriptions inside the temples. The conventional lighting systems used are tube lights and bulbs which are unsuitable for the ambience. The wires gape through the pillars in an unsightly fashion.

Solving these problems, this lighting project creates ambient lighting that merges into and enhances the look of the building. A series of lights are neatly hidden behind laser cut steel panels that stick to the temple walls using specially designed adhesives. The adhesives are customized for the temple walls based on their material. Ornamentation replicating the temple’s surface designs are carefully selected and laser cut onto the panel.

Foldable Helmet

Lugging around a bulky helmet is so inconvenient that millions of two wheeler riders and their pillions would chose to go without one—even though this may be a fatal choice. This Helmet is designed to improve this user experience: The main feature of the helmet is its ability to easily collapse with a single flick becoming compact and easy to carry.  The helmet design has gone through many iterative layers of safety, anatomy, manufacture, economics, ease of use, ergonomics and style considerations. Apart from the two piece locking mechanism, the materials used for the cushioning have also been modernized for added compactness.

Affordable Vein Tracer

The thought of getting injected is traumatizing to many and when you have to undergo multiple attempts of needle insertions – It’s nightmarish.

This simple light-weight device humanizes a simple technology (NIR Spectroscopy), helping medical practitioners to identify the veins easily, during vein-puncture procedures.

The Convenient and affordable vein tracer helps to locate the vein in the first attempt. Hence, reducing patients’ trauma.  Difficulty in locating the veins —especially in children, darker skinned and obese people—leads to unnecessary multiple needle pricks that cause agony due to injury and time taking process. NIR Spectroscopy is an existing technology which can easily be applied to solve the problem. The LED lights are deflected by the deoxygenated blood —giving a clear silhouette of veins. However for this technology to be actually used by the masses— in blood camps, small and medium sized hospitals—it needs to be extremely easy to use, ergonomic and a low cost product.  All these issues are well addressed by this Vein Tracer.

The USP of the device are as follows:

  • Works on diverse users – obese, dark skinned and geriatrics
  • Affordable product – the device is developed at a cost close to Rs.2000, enabling small hospitals and clinics purchase the device
  • Considers healthcare standards
  • Product usage needs minimal training
  • Device is portable
  • Has healthcare aesthetics.

Currently a working prototype has been developed and pilot testing is in progress.
