Problem Statement
◦ Solar-powered go-kart has insufficient energy in either short or long
distance. The relationship can be seen in speed versus distance. A
higher speed can be achieved when travel in short distance and vice
versa.
***Boundary Condition***
H1: The path travelled is only a straight road.
H2: The go kart can only accommodate one person.
H3: The maximum weight of a person is 70kg.
Benefit and/or Impact if Problem Resolved
◦ The solar powered go-kart will be able to travel with the maximum
efficiency of energy at a longer distance and higher speed.
◦ The overall weight of the go-kart will be reduced and the overall
stability of the chassis will be enhanced.

Description
5.2.3 A mechanical field is introduced to the model. In order to maximize
adaptation and synchronization, the newly introduced substance can
work together with the solar panel and its tracking.
5. Engineering ContradictionEngineering Contradiction
Solar Panel
If the solar panel is removed from the go-
kart, then lower down the weight of go-kart,
enabling the go-kart to move faster and
provides greater efficiency, but required
higher cost for modification.

6. Heavy Weight
If the weight of the go-kart is reduced, then go-
kart will be lighter, enabling the go-kart to
move faster and provides greater efficiency, but
required higher cost for modification and not
stable.
