5.1 JUSTIFICATIONS FOR SCORE GIVEN

Design No. Objective Score Allocated Justification for the Score
1 Safety 16 The design will not be having any safety issue
Ease of use 18 It will be useful for the long time because of the perfect prototype built
Portability -6 Because of the so many wires and other connections, it is not easy to carry from one place to another
Use of standard parts 8 Standard parts are used like 'Ball bearings', 'Digital gear indicator', 'Acrylic sheets' and 'Foam board'
Cost 7 The cost of the design will be affrodable
2 Safety 16 The design will not be having any safety issue
Ease of use 9 The design is usefull for only for the short time
Portability -6 Because of the so many wires and other connections, it is not easy to carry from one place to another
Use of standard parts 8 Standard parts are used like 'Ball bearings', 'Digital gear indicator' and 'Acrylic sheets' and 'Foam board'
Cost 7 The cost of the design will be affrodable
3 Safety 16 The design will not be having any safety issue
Ease of use -9 Because of the assembly part of the design, it is used only for very short time
Portability 6 Because of the small size, It is very easy to carry from one place to another
