JUSTIFICATIONS FOR SCORE GIVEN

Design Objective Score Allocated Justification
Motor flip clock Aesthetics 9 Motor flip clock has more aesthetic looks as compared to Floating gear train clock
Cost 3 Motor flip clock is more budget friendly
Accuracy 9 Motor flip clock is more accurate due to a smoother gear rotation and less friction
Functionality 8 Motor flip clock is more compact because it does not need a large hanging weight
Feasiblity 7 Motor flip clock is difficult to maintain accurate gear alignment and flipping motion
Linear sliding clock Aesthetics 9 Linear sliding clock provides a clear and attractive design
Cost 3 Linear sliding clock is under the given budget and taken as the refrence
Accuracy 9 Linear sliding clock is taken as the refrence for the accurate time measurement
Functionality 8 Linear sliding clock is functional to operate and taken as the datum
Feasiblity 7 Linear sliding clock is more feasible to operate and taken as the base to compare
Steampunk open gear clock Aesthetics 9 Steampunk open gear clock is more asethetic in looks as due to compact design
Cost 3 Steampunk open gear clock is more budget costing as it require more gears for decorative purpose
Accuracy 9 Steampunk open gear clock is more accurate due to controlled gear mechanism and adjustable speed of motor
Functionality 8 Steampunk open gear clock is more functional because it depends on continuous electrical power and a motor, reducing its mechanical independence
Feasiblity 7 Steampunk open gear clock is more feasible it has a simpler construction, requires fewer precision mechanical components, and is easier to assemble, control
Planetary Gear Clock Aesthetics 9 Planetary gear clock has more attractive looks and asthetic appearence
Cost 3 Planetary gear clock is more way expensive to build
Accuracy 9 Planetary gear clock is more accurate in time keeping due to interaction of gears and controlled gear movement
Functionality 8 Planetary gear clock is more functional in operating as it only runs on mechanical movement of gears
Feasiblity 7 Planetary gear clock is less feasible as it involves more complex mechanisms
Cam and follow clock Aesthetics 9 Cam and follow clock is less asthetic in looks and more exposed
Cost 3 Cam and follow clock is more expensive to build
Accuracy 9 Cam and follow clock is more accurate due to precise motion control and less backlash
Functionality 8 Cam and follow clock because it provides controlled, repeatable and precise movement of the clock hands
Feasiblity 7 Cam and follow clock is less feasible as it requires more complex and precise mechanism and alliginment
