Smart Burner
Redesigning of the existing smart burner, considering the factors - Optimizing the size of enclosure, reduction in weight, improve accessibility, and making visual unity with the burner. Industry sponsor - Forbes Marshall Pune Project duration: 45 days
Tilt Options for ergonomic viewing
Study of existing Product
Study of components Insights • The first prototype was made in sheet metal (1.5 mm).Hence the whole enclosure is heavy. • There is huge void space inside the enclosure, thus making it bulky. • Access to some components like eagle is very difficult • Ventilation is not provided, • Visibility and access to touch screen is worse • Boxy in nature • Not suitable as a stand alone product
Re-packaging of components
Packaging of components considering the factors, reduction in volume, ease of access and maintenance friendly, and final assembly to the burner.

Final form and details The upper body is made of FRP to reduce weight and to explore the possibilities of giving visual appeal. The new product was able to reduce the bulk and total volume with respect to original design. The form of the product is derived basically from the packaging and to bring visual unity with the new Forbes marshal burners and to be used as stand alone product. The colour was chosen on the basis of existing Forbes marshal colour scheme and to give a high tech feeling

Analysis
Line man -Job profile: • • • • • • • • •
Government Job ITI or diploma is minimum qualification Works in 3 shift, (8 hours a day) Normally two people goes together to a site Risky jobs and are equipped with safety jackets, boots etc Body needs to be flexible Need to travel a lot They are provided with a bike to reach all nooks and corners of the city Carries mobile phone (They are given updates regarding complaints, alerts etc through this)
Work area identified and Task flow Job which frequently happens is fixing loose contacts, fuse changing and providing new connections x
Arrange the necessary tools and accessories required Reach the site
Find a support for body to work up on
By bike By walk
Unwind the previously wound wire
Confirm the complaint received
x
• • • •
Awkward postures while at work Increase the efficiency at work Chances of accidents are more Safety at work can be improved
Clean the service wire/ cut a small portion
Identify the location of loose contact/ breakage If it is a problem on the post, climb on the post (Maximum problem happens in the posts)
Design opportunities
Using ladder( if available) Without using ladder
Clean the service wire/ cut a small portion Wind back the wire descend down
Design Constraints • User wont use anything which reduces the efficiency even when the product makes their work safer. • Woks on live more most of the time • They carry only those things which fits in the carrier attached to bike.
Design brief There is a need to design a portable tool which helps the ‘line man’ to wind/ unwind the service line on the main electric power line with more efficiency in operation, increased safety and better work ergonomics work condition.

Details Plier tip Gear ( Delrin) Split sleeve High carbon steel
Rubber grip Spring steel clip Body case ( ABS + PC)
The body is subjected shocks from resulting from falling. Hence ‘ABS + PC’ was chosen as it is good shock absorber. For the working parts ,as in gears and rack ‘Delrin’ is used which is self lubricating resulting in smooth action and is light weighted. High carbon steel is chosen for split sleeves, which otherwise abrade when wire continuously rub against it.

Process flow
Wet waste
Dry waste
Hazardous waste
Dry waste includes all items that are not considered wet or soiled items, includes both recyclable and non-recyclable materials
Wet waste includes all food and yard waste, and anything that would contaminate your recyclables.
These items can cause fires, harm those people who come into contact with them, damage machinery or harm our environment.
•Plastic bags Card board, Paper, Plastic bottles, Glass, Cloths, Metals, Etc..
• Battery, Chemicals, Medicines Razor blades, Fertilizers, Glues Alcohol, Etc..

This link of the chain is not happening 100%. Hence whole system fails
Approaches • Interactive bins which attracts the user to segregate the waste • User should get some benefit if he segregate the waste in to dry and wet • Forcing the user to segregate the domestic waste
Segregation Recycle
Ideation
The ideations were based on the approach “ forcing the user to segregate wet and dry waste� . The bin is made of two parts plastic container with lid and a paper bag. If the wet waste is put in the paper bag, it attracts flies and stings and he will be forced to dispose that in Plastic bin. For dry waste user get an advantage of not opening the lid for disposing the waste and there by easily doing the job. The product also needs a solution in the system level where the bin’s will be provided by the municipality and takes strict decision on collecting the waste
Concept validation. A mock up was made and tested in two houses. People where provided with a plastic container with lid and one open paper bag But sill people perceive dry leafs and onion peels as dry and they put those in the paper bag. But the wet waste ( food left over) were able to segregate. Thus product helps in creating opportunity in the municipality end to segregate the recyclable wastes (from the dry wastes), which otherwise could have been difficult. Thus making the recycling of plastic and paper easier.
