ABSTRACT
Under this report ,design of 3 wheeler cart is done by using Computer aided design .This
cart is first created by Leonardo da Vinci and he named this vehicle as self propelling
cart .The prototype of this cart is recreated in this report .The manual spring mechanism is
used to power this cart as a key is directly connected to spring .When the key is rotated
then spring get compressed and absorb the energy then spring transfers the energy to gear
arrangement which is directly connected to wheels of cart .The front wheel is design in such
a way to steer it accordingly .

INTRODUCTION
Da Vinci was not only designer but also an artist and a painter and that also reflect in his
work as well .His one of the best work was propelling cart and this cart was impossible of
design at that time without necessary resources .This cart is a masterpiece having perfect
use of gears .All the parts of cart were recreated using solidworks CAD software . Rendering
and detailed drawing of all parts are prepared for manufacturing purpose . Analysis of
wheel of cart is done and comparing it for prototyping purpose and cnc manufacturing .
DESIGN PROCESS
The main focus of design process is to recreate the prototype of 3 wheeler cart effectively
considering all design aspects .

Figure 1.1 Cart design concept
 Under the design concept , a rough sketch of 3 wheeler cart is obtained. This sketch
gives us the basic idea about the product visualization. The above sketch shows that
gears assembly is surrounded by frame .This frame not only kept all the parts
together but also carry out all the load act upon it .1
1 Davinci, Leonardo (2011). The Notebooks of Leonardo Da Vinci. Lulu. p. 736.
 3 Wheeler cart should be designed similar to propelling cart and all the main
components like spring , gears and frame should be used accordingly .
 3 Wheels are used in this cart , front single wheels is used for direction purpose and
backward two wheels provide the motion .2
DESIGN SPECIFICATION
Under design specification all the parts of 3 wheeler car should be specify accordingly . All
the component are explained below .
1) Truss/Frames
7 | P a g e

INNOVATIVE PRODUCT DESIGN & MANUFACTURE
Truss/Frames are the structure members generally used to carry loads and coupled
multiple parts in single unit for smooth operation of assembly. To carry the weight of
multiple gear units , here two types of truss are used .
Truss/Frames used are:-
a) Bottom Truss/frame
b) Top Truss/frame
a) Bottom truss
According to its name suggest ,bottom truss present at the bottom of gear
assembly .The load of all mechanical components are directly act on this
truss .At the surface of bottom truss , multiple threaded holes are
present .These holes are used for mounting and rotating gear shafts . Other
holes are used to fastened the bolts with other frame . Fillets are present at
corners of truss for stress reduction.

Manufacturing process -
The shape of frame is non uniform , So all the linear parts are joined together with
fasteners , at necessary places holes of required diameter are drilled . Fillets are

DESIGN EVAUATION
As a prototype , consider the cart having speed of 10 m/second .
V =10 m/s
Cart Weight = 1000 Grams
Formula
Kinetic energy = ½ x mass of cart x velocity^2
KE = ½ * 1000/1000 * 10*10
K.E= 50 Joules
So this cart need 50J to reach speed of 10 m/s
But spring energy is equal to kinetic energy
S.E = K .E
½ * k *x = 50
k = spring constant= 800 N/m
Apply values we get
x =125 mm
Dia meter of coil = 12 mm
So its Perimeter = 12 x pi= 12*3.14
=37.7 mm
No . of rotations = 125 /37.7
= 4
So maximum 4 rotations needed to reach the cart to 10 m /second .

DFMA PRINCIPLES & ANALYSIS
DFMA refers to design for manufacture and assembly .DMFA is technique that focus on
efficiency in manufacturing and assembly of a product by simplifying all process include
under it .It main motives to manufacture and assembly the product in minimum time and at
least cost .
Main principles of DFMA
 Simplify the automation process by reducing number of parts in assembly .The 3
wheeler assembly is completely automated .
 Encourages to use standard parts that are easily available rather than complex
manufacturing that increase cost of product .In 3 wheeler assembly ,standard parts
like gear ,spring , shaft hub are used .
 Reduce the use of flexible components like gaskets, seal ,rubber . As assembly of
these parts are more difficult .No flexible part used in 3 wheeler assembly .
 Use adhesive and snap type fitting for assembly rather than fasteners .
 To simplify manufacturing , parts design should be simple and unnecessary features
on parts should be avoided .
Advantages of DFMA
 Cost of assembly and manufacturing becomes low .
 Time required for assembly and manufacturing is less .
 As numbers of parts reduces then chances of parts failure also reduces therefore
reliability increases .
 High quality of product is achieved .

DESIGN VALIDATION
Consider the factor of safety is 2 and design the wheel of cart , considering its weight of
7000 grams.
Weight on wheels = 7*9.81 N = 70 N ,To maintain factor of safety is 2 , load applied should
be 70 x 2 = 140 N
As Applied load is 140 N on wheels centre and check the maximum stress and deflection
produced by the wheels .Diameter of shaft is 3 mm.

DEFLECTION
Value of deflection obtain is given below
Minimum :- 0.00 mm
Maximum :- 0.166 mm
FACTOR OF SAFETY
Factor of safety is the ratio of yield stress to maximum stress generated while applying load.
Yield stress is maximum permissible stress for a particular material after which deformation
takes plate. Here Yield stress is 45MPa and maximum stress generated is 31.39
MPa .Although this design is safe but factor of safety value of 2 is not achieved
F.O.S = 45/31.39 =1.43
So changes need to be done to reduce the maximum stress value and achieve the factor of
safety to 2 .
24 | P a g e

INNOVATIVE PRODUCT DESIGN & MANUFACTURE
CHANGES IN DESIGN
To maintain the factor of safety of 2 and above , necessary changes need to be done
accordingly .Earlier the shaft and hub of wheels having diameter of 3 mm .
According to formula below , stress is inversely proportional to Moment of inertia(I) .
For shaft
I =3.14 *D^4 /32
This shows that to reduce the value of maximum stress ,diameter of shaft need to be
increased . Now in new design diameter of shaft is increased from 3 mm to 4 mm due to
which stress value will reduce .
The below picture shows that diameter of shaft change to 4mm
Now kept all the procedure same i.e fixtures , loading and run the result with new design.
RESULT
As all the input parts are completed now the run the analysis and new results are obtained
shown below .

DEFLECTION
Value of deflection obtain is given below
Minimum :- 0.00 mm
Maximum :- 0.21 mm
FACTOR OF SAFETY
Here Yield stress is 45MPa and maximum stress generated in new design is 20.65 MPa .
Although this design is safe and also factor of safety value of 2 is also achieved .
F.O.S = 45/20.65 =2.17
So changes done are effective to achieve the factor of safety to 2 or more .
Conclusion
In 1st case when the diameter of shaft is 3 mm and applied load is 140 N then although the
design is safe but factor of safety of 2 need to be achieved .To increase the value of factor of
safety , maximum stress occurs due to applied load need to be reduced . So in new design
diameter of shaft is increased from 3 mm to 4 mm so that its moment of inertia get
increased and maximum stress reduced . So after increasing the diameter of shaft to 4 mm
the maximum stress value reduced to20.65 MPa and factor of safety of 2 is successfully
achieved . So overall design is safe .9
