This document summarizes the design process for an electric cart intended for use at airports by personnel. It describes information gathering including user studies and market research. Key user needs were identified as easy maneuverability, comfortable seating, and long battery life. Several design concepts were iterated on with a focus on ingress/egress, battery integration, and ergonomics. Dimensions and a 1:1 scale model were used to evaluate the final design. The design was inspired by studying interior designs at various airports.

1. Design of an electric cart for
Airport Terminal use
Ai T il
Project III by Jithesh.R
Guided by Prof. K.Munshi

2. Introduction
• The project aims at designing an
electric cart for airport personnel to
move within the premises of the airport
Methodology
Information Collection Formulating Product Brief
Defining a problem statement
Final Concept Iteration on Concepts Conceptualisation

3. Problem Statement
• Transportation within the airport
terminal with a silent non polluting
system addressing the needs of the
airport personnel or passengers

4. Information Collection
• User study
• Data collection of the current market
D ll i fh k
supplying such transportation solutions
• Technical data collection

5. User Study
y
• Interview with the Airport Managers
• Interview with Airport personnel (security, engineers, workers)
• Interview with passengers
• Observation of the Airport
• Observation of work pattern of airport personnel

6. Observations
• Airport authority states that privatisation
will make the airports even bigger
• Currently all maintenance and service
jobs of the airport are on contract basis
• The contractors use different vehicles
to cater to their needs
• Private airline companies introduced
golf carts to cater to their customers
and staff
Indhira Gandhi International Airport - Delhi

7. Chhatrapati Shivaji International Airport - Mumbai
Private airlines like Jet Airways and Air
Sahara get vehicles modified for airport
use

8. Domestic Airport - Mumbai
Ground Services in India

9. • Contractors use different equipments to
do their jobs
• The vast space of the airport demands
a transportation solution to these
p
workers who are currently taken around
in jeeps and vans in India

10. • Security and Airport Official needs to
move within the terminal to look into
various factors before a flight takes off
and after a flight lands
• Airport Officials being in fresh condition
helps a lot in efficient functioning of the
airport

11. • Patients and old age people who cant
walk are taken care of by Airport
Authority or the Airlines they are
travelling by
• In India usually wheelchairs are used
and in case of bed ridden patients an
ambulift is used

12. • Airport officials’ transportation within
the terminal is a need in airports
abroad and also new airports in India
which are big g
Cochin International
Airport
Incheon Airport – S
Seoul, Bilbao S
Sondica Airport – Northern S
Spain
Lambert Airport – St. Louis
Korea

13. • Some products existing in the line of airport transportation solutions by
MOTREC (USA) and Club Cart (USA)

14. Analysis
• There is an evident need for reducing the time of travel of the
airport maintenance and service crew
• The same applies to the airport authority officials
pp p y
• A vehicle indoors is a feasible solution for efficient functioning
of these departments

15. User identification
From the observed four groups of users one group is selected
• Airport Personnel
• Airport Security
• Passengers
• Airport Maintenance and Service

16. Product Brief
• An electric powered cart to transport airport officials within the airport
terminal
• Ease of ingress and egress
E fi d
• Relaxed and comfortable seating while on the vehicle
• Easy manoeuvring of the vehicle with very small turning radius
• Facility for holding files and work sheets of the officials
• Low maintenance
• A work time of 8 hrs before 80% battery drain (at full working condition)
• Easy charging options

25. Pre – Final Concept

26. Choosing the tyres, wheels and platform
• A 16 wheel (of Bajaj Sunny) was
16”
used first to try out the vehicle
layout
• A 9” tubeless tyre and 4”
aluminium wheel rim used in go-
karts were identified as a better
option for the vehicle
• The direct motor drive can be
connected via the connector

28. Frame of the Vehicle
• The final frame (1:5 scale model)
of the vehicle is shown aside
• The 8 batteries are accommodated
in the two rectangular guide
frames

29. Styling

31. Evaluation of Styling
• Three tests were conducted to arrive at a conclusion on styling
of the vehicle
– Comparative Evaluation
– Grading on each styling
– Feedback on what people like and don’t like about each
don t
style

32. Final Concept

33. Driving posture derivation
The driving posture was calculated after evaluating
different people as subjects for seating
ff f

34. Thermocol model t evaluate f
Th l d l to l t form and d
proportion of the vehicle, corresponding CAD
model was made to understand the overall
form

35. The front wheels are powered by two 1 HP DC
motor and steering the vehicle is executed
electronically by variable speed steering
mechanism.

36. Final Concept

37. 1:1 Grid Proposed vehicle
p at o
platform
From the 1:1 grid dimensions were extracted for
concept detailing, the grid helped in
understanding the size of the vehicle and also to
find
fi d problems related t i
bl l t d to ingress, egress and
d
seating posture

38. Iterations on Final Concept
Work on the back support for the occupants
Steering column and ingress – egress ease

39. Accommodating the battery
casing
Integration of the base and
g
battery case

40. The design evolution is shown above, the
design errors were rectified to arrive at the final
product
• The first two stages ingress egress was a
problem due to the protruding wheel well
• Folder and file holders were not placed at
appropriate positions
