PAPR POWERED

RESPIRATOR

Mohak Parikh

Identifying the need !

As the world saw the onset of rising coronavirus cases, the need for medical and personal protective equipment saw a sharp rise in demand. PAPR was the need for the hour for first responders and medical staff. Many medical equipment supply chains experienced disruption causing the medical industry to depend on local or national sources. PAPR was one such product that was not included in the portfolio of most Indian companies in the field.

What is the purpose of PAPR ?

A Powered Air Purifying Respirator (PAPR) is a device used by medical personal, firefighters, and other first responders. It takes ambient air contaminated with one or more types of pollutants or pathogens, actively removes (filters) a sufficient proportion of these hazards, and then delivers the clean air to the user's face or mouth and nose.

They have a higher assigned protection factor than filtering respirators such as N95 masks.

During tenure of my work for Sure Safety and VEXMA Technologies Pvt. Ltd. : -I took an active part in various discussions during the product development process.

-I have explored, researched, and understood the design language complimenting the usage and the market.

-Understood the components and working of a PAPR and made design decisions considering both the engineering and aesthetical aspects.

PROTOTYPE ENCLOSURE

Mohak Parikh

The Challenge

My Client

A unique challenge was given to me by a private company to design a prototype enclosure for initial beta testing of their underdevelopment IoT product. The client's brief was that they wanted something aesthetically rich, can be easily dismantled, and allowed space for a change in the component during the development process.

UltimuslabTM Blue Reef Tech PVT. LTD. Ultimus Lab is a creative design and digital agency specialising in delivering user-centric designs and digital branding solutions, utilising the latest tools and techniques. They are committed to shaping the culture and future of products and businesses by delivering comprehensive branding and digital design solutions, that speak volumes for themselves.

The solution I provided a design that does not require a tool to be dismantled, and I also improved the design of the snap-fit joints to allow frequent dismantling. Structural webbing is provided inside to increase the strength of the enclosure.

An innovative and unique way to support the internal components was devised, which required to laser cut a card-board with a cut-out of the component such that it would snap with the internal webbing of the enclosure. The design was then processed and optimized for 3D printing. A 3D printed prototype was developed under my supervision.

MODULAR AND ADAPTABLE Non-permanent laser cut card-board cut-outs to hold components in place. It snaps with the internal webbing. It also allows easy component change by laser cutting cut-out of required size and shape.

ACCESSIBLE Screw/bolt less design allows dismantling without any tools.

DURABLE Curved male joint provides better resistance to bending during disengaging two halves, hence prevents breaking of the male joint allowing frequent dismantling.

STRONG Internal webbing provides better structural strength.

SUSTAINABLE Recyclable and biodegradable Poly Lactic Acid (PLA) enclosure.

Pringles Tear Away Mohak Parikh

The problem Are you tired of an unfinished Pringles cylinder taking up space in your backpack? Fed up with getting your whole palm oily while fetching for chips! Not only does it bother you, but it also takes significant space inside trash cans, waste transport trucks, and land fields. The empty space inside the cylinder also allows vertical movement of chips and hence breaking them.

Year 2019

Ideation and brain storming

Mohak Parikh

The solution A tear-away packaging that lets you tear away a portion of the cylinder every time you consume 26 chips.

Preventing oily hands and saving you space! After consumption, the cylinder gets reduced to three flat cutouts, which take much lesser space inside trash cans and trucks hence allowing more trash to be transported at a time.

Reduce the size as you eat

Occupies less space in the trash can and truck.

Mohak Parikh

Aluminium foil fused with the cardboard cylinder from inside for providing a barrier to air, moisture and light hence keeping chips fresh.

Printed instructions

Resealable frosted plastic lid

Recyclable paper wrapper with tear away instructions, flavour and nutrition information. Fused with the cardboard cylinder on the outside.

Bottom tin cap

MORPH POLE Mohak Parikh

About I designed the morph pole as an entry to the Urban chair competition organized by Archasm. The competition aimed to design an urban modular furniture that can be placed on path-ways, subways, or other public places.

Morph pole is an urban and modular furniture that is suitable for various on the go tasks. It can be transformed into a cafe table, a standing work platform, a recliner, a seat for a toddler, and much more.

Year 2020 Abacus

Ideation and conceptual sketching Mohak Parikh

An array of modules can be placed to increase the permutations and combinations

The seat can be adjusted to a desired height and rotated as per preference. It can be transformed into a chair, coffee table, standing table, recliner and much more.

Canvas roof can be attached for regions with tropical climates

Extension pillars can be easily attached

Mohak Parikh

The platform can be rotated 360 degrees with 30 degrees steps to be set at a desired angle. It can be used as a back support, a writing or reading desk and more.

The seat can be slided up and down to a desired height ranging from 1' to 5'. This allows the user to use it as a seat, a cafe table, a standing table and more.

2 in 1 Security chair

Mohak Parikh

The Problem Most of the security guards in India have inaccessibility to a security cabin. But they all have one thing in common that is a chair. Unfortunately, unlike a gun or a rod, a chair wouldn't help in dealing with an unlikely circumstance.

The Solution While waiting outside an ATM, an idea sparked into my mind—the idea of designing a chair that can also be used as a shield.

Speaker Mohak Parikh

The Problem While searching the market for a portable speaker that could also suffice to be an inhome speaker, speakers meeting both criteria were too large and heavy to be easily portable. While the easily portable speakers were too small to be an in-home speaker.

The Solution A home speaker with a detachable portable speaker. Surprisingly causal events during that period helped me incorporate art and the golden ratio into the speaker.

This speaker is not just a piece of audio equipment, but it also is a piece of art that empowers the rural skills - Kantha and hand-formed copper sheet; present in India.

Ideation and brainstorming Mohak Parikh

Kantha is a centuries-old tradition of stitching patchwork cloth from rags, which evolved from the thrift of rural women in the Bengali region of the sub-continent - today the eastern Indian states of West Bengal and Orissa, and Bangladesh. One of the oldest forms of embroidery originating from India, its origins can be traced back to the pre-Vedic age (prior to 1500 BCE).

While the word kantha has no certain etymological root, it is believed to be derived from the Sanskrit word kontha, meaning rags. In modern usage, kantha more generally refers specifically to the type of stitch used. The earliest and most basic kantha stitch is a simple, straight and running stitch. In West Bengal, India, artisans focus on a specialised form of geometric patterned kantha, called Partola.¹

Mohak Parikh

Copper smithing has been practiced in India since an early era. Utensils, coins, and art were the main products produced. Traditional hand hammered and formed copper vessels are still used by many households in India due to copper's health benefits. The smiths generally use ancient tools or lathe in making the products.

The shoe sole experiment It is a follow up to The Sneaker project. In this project, I experiment with the shoe sole in order to lighten it using the latest technologies available. Latest technologies include latticing using nTopology software and generative design using Fusion 360 software. All experimentation with the design was done considering additive manufacturing using elastomeric materials.

Bicycle Saddle Mohak Parikh

About This project is the result of an exercise to learn advanced CAD modelling techniques and rendering.

Fusion 360 was used for both designing and rendering.

Process I choose to replicate, redesign, and experiment with the bicycle saddle as it is a part of my daily activity. I experimented rendering with different materials and views. I also figured out ways of showing cutout sections to show the inner parts. I also learned creating and importing materials and textures for rendering.
