Weighted-Properties Method (Digital Logic method)

STEP 1:- Each material property (“criteria”) is assigned a weighting factor (wi ) between 0 and 1 relative to its importance to the overall design.

Material Selection Process: Upper Body

Material Selection Process: Upper Body

STEP 3:- Weighted property index is calculated by multiplying the scaling factor by the weight factor. Then the summed for the criteria.

Material Selection Process: Upper Body

Results From Various RelationsWe have reduced our primary problems areas and found out possible areas where we could redesign and increase the part functions efficiency

Possible redesign parts:

Front upper body

Back upper body

Screw fasteners

Insulation foils

Switches

Fan

Possible Redesign Parts ExplainedBodyDecreasing thicknessReduced material cost Joining front and back bodyReduced partsDifferent shape rear For higher efficiency of air intake

Insulation foilsUsing alignments hot spotsUsing 4 instead of 2 to counter heating problem that may arise from reduced

body thickness

Possible Redesign Parts Explained

SwitchesUsing sliding switch type instead of pressed typedUsing textured plastic material or dimpled surfaced button for better grip

Screw fastenersUsing metal fasteners

FanUsing better aerofoil profile
