Justification:-

Concepts Objectives Score Given Justification
Concept 1
Semi Automatic 0 This is semi-Automatic
Portability - This is less Portable as weight of chain is heavy
Efficiency + This is more efficient as they transmit motion over small centre distance of shafts
Cost - This has higher cost due to the metal sprocket system
Aesthetics + This design is better looking aesthetically
Concept 2
Semi-Automatic 0 This is semi-Automatic
Portability 0 This design is portable
Efficiency 0 This design is efficient as we can increase belt speeds
User friendly 0 This design very user friendly as accidents decreases
Cost 0 This design is budget-friendly
Aesthetics 0 It has good appearance
Concept 3
Semi-Automatic 0 This is semi automatic
Portability + This is portable as it is light weight
Efficiency - This is less efficient as it requires more force to turn the spring
User friendly 0 This is also user friendly as there is less accidents
Cost + It is of low cost
Aesthetics 0 This is also aesthetic
Concept 4
Semi-Automatic 0 This semi-Automatic
Portability 0 This is portable as it is average sized
Efficiency ++ This is very efficient as there is less power loss due to less friction
User friendly ++ It is very user friendly as there no harms
Cost + This is budget friendly
Aesthetics + This is very good looking in terms of aesthetic
