Industry sponsor - Forbes Marshall PuneProject duration: 45 days
Tilt Options for ergonomic viewing
Study of existing Product
Re-packaging of components
Study of components
Packaging of components considering the factors, reduction in volume, ease of access and mainte-nance friendly, and final assembly to the burner.
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 Selected layout
Post clamp mechanism is selected for tilt lock since it withstand more vibra-tion and it locks the whole tilt assembly in a quarter rotation
Lock design for tilt
Lock design for lid
Ergnomics of viewing
For Ergonomic and better viewing of LCD screen, the whole assembly is lilted in a particular angle.This is to accommodate variation in operator heights and platform in each company. Also tilt is provided to prizm to get more angles

The lid has to be locked in a position while doing maintenance and assembly. A linkage system was designed which helps to hold the lid effectively and with reduced effort. A mock up was made to validate the concept
1. Lid opening
2. Lid locks in to it’s position and stay in it’s posi-tion even after applying pressure from top, ensur-ing safe working condition
3. Closed position

Final form and detailsThe 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 de-rived 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

Design opportunities
• Awkward postures while at work• Increase the efficiency at work• Chances of accidents are more• Safety at work can be improved
Design Constraints
• User wont use anything which re-duces 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.
Analysis
Job which frequently happens is fixing loose contacts, fuse changing and providing new connections
Work area identified and Task flow

Details
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.

Why segregation is not happening?
Laziness In hurry..
Lack of awareness Not at all bothered about consequences
By mistake
Done by servants..

Wet waste Dry waste Hazardous waste
Domestic 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.
•Vegetables, Fruits, Food left over, Nap kin, Dry leaves Meat Etc..
•Plastic bags Card board, Paper, Plastic bottles, Glass, Cloths, Metals, Etc..
• Battery, Chemicals, Medicines Razor blades, Fertilizers, Glues Alcohol, Etc..

Research Analysis
IdeationThe 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.
Details
A mock up was made and tested in two houses. People where provided with a plastic con-tainer 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.
