5.2 Justification for score given

Design No. Objective Score Allocated Justification for the Score
1 Mechanical Display 12 This design has the rotating dial familiar to the rotating tyres which represents the count mechanically better than any other design shown below.
Aesthetic 10 Each number is represented on one of the cube structure of the rotating dial made of alternate colors which makes it aesthetically pleasing and good looking.
Light Weight 6 A single rotating dial consists all the 10 numbers 0 to 9 hence making the counter machine light in weight.
portability -7 The counter machine is made of round dial and can alter the angle of rotation while carrying it harshly hence may give inaccurate readings after moving it from one place to other.
Automatic(working) 9 As the rotating of the dial,reset and indication on completion works without any human actions,making the counter machine automatic.
2 Mechanical Display 6 Moving display making it a mechanical one.
Aesthetic -5 It is non aesthetic as its movement is similar to that of turning pages.
Light Weight 12 It is light in weight as compared to that of datum as it contains placards on which the number is highligted.
portability 7 Portable enough than datum for user convenience.
Automatic(working) -9 Reset and initial point has to be manually set .
3 Mechanical Display 0 Used a reference display.
Aesthetic 0 It is aesthetically pleasing and used to compare other designs.
Light Weight 0 Light in weight.
portability 0 Portable but may cause inconvenience for the users.
Automatic(working) 0 It is automatic and used as reference for the other working criteria.
4 Mechanical Display -12 The sticks move but all the other number are visible while a single number is being displayed.
Aesthetic 10 It is aesthetically pleasing and good looking as compared to datum.
Light Weight -6 Multiple rods used hence making it heavier than datum.
portability -7 Large surface area making it inconvenient for the user to carry it from one place to other
Automatic(working) 9 The mechanism is automatic after an user stimulus provided.
5 Mechanical Display 6 As all the 7 segments move to display a single number makes the display a mechanical one.
Aesthetic 5 It replicates the 7 segment LCD display making it attractive.
Light Weight -6 Makes heavier as multiple hinges and gears will be used in making it.
portability 7 It is fitted into a cuboidal box making the machine portable.
Automatic(working) 9 Working does not require any user interaction once the stimulus is provided.
