Product Design and Prototyping
Redesign of Table and Chair for Engineering Drawing
AIM: Identifying the user needs and parameters of Human Factors to create an ergonomically designed chair and table for Engineering Drawing.
Collaborators: Suyog Deshpande, Kumar Mayank and Diya Gangopadhyay
Guide: Prof. D. Chakravarty
PROJECT ACCOLADE:
The product was showcased in the international conference for Human Factors Enginnering - HWWE 2005
The product was mass produced and is currently being used by the students of IITG.
Project Brief: The target user groups are engineering and architecture students. The project aimed at understanding the difficulties of students in using the existing engineering drawing table and chair at IITG. In engineering drawing course students have to produce precise geometric figures and diagrams, using various instruments. This necessitates a flat, solid surface to support their fine level of work. Also the long hours of working demand a design that lays minimum strain on human body, thus necessitating calculation of precise anthropometric data. The IIT Guwahati engineering students were taken as the representative users for the purpose of this project.
Methodology:
Market survey and contextual enquiries through questionnaire and interviews to analyze existing problems. -->
Literature study and optimization of anthropometric data to get the appropriate dimensions. -->
Redesign of the table and chair in accordance with the ergonomic data and user data collected along with value additions. The value additions included providing a pen/pencil holder on the surface and also space for keeping spare tools and bags below the surface. -->
Development of full scale prototype and usability testing with target users.
Redesign of Trolley for Household Use
AIM: Identify the user needs and create an ergonomically designed trolley for household purposes
Collaborators: Diya Gangopadhyay
Guide: Prof. A.K.Das and Prof. Ravi Mokashi Punekar
Project Brief: The target user group is mainly women of middle class families. The project aimed at understanding the difficulties of users in shifting heavy goods within the house like LPG cylinder. On an average each family had to change cylinder twice a month and on a major account it was housewifes who had to do the task. They faced problems each time in shifting it in and out of the kitchen cylinder closet.
Apart from LPG cylinders, users also stated need for a foldable and small trolley which could be used for shifting other household commodities like books, heavy show pieces, etc. A full scale prototype of the trolley was developed catering to the requirements of the users. Testing with target user group was also conducted in which the product was found to be well accepted.
Key Features:
Foldable base
Small size
Adjustable height
Sleek look and light weight
Design of a Mosquito Repellant
AIM: Designing an innovative form/structure for a mosquito repellant
Guide: Prof. A.K.Das
Project Brief: Many forms were generated during the ideation process to come with a dynamic form for the mosquito repellant keeping the ergomic and economic issues in mind. The forms were generated using Solid works. The best model was selected and a prototype was made in RPM (Rapid Prototyping Machine). The following image shows the various forms that were developed during the process.
