S.C.A.M.P.E.R

Feasibility Analysis

COW’s Matrix

S.C.A.M.P.E.R 

S = Substitute

C = Combine

A = Adapt

M = Modify

P = Put to another use 

E = Eliminate

R = Reverse

Substitute: Substituting part of the problem/product/process for something else.
Example: Vegetarian hot dogs

Combine: Combining two or more parts of your probortunity (= merging of the word “problem” and “opportunity”) to achieve a different product/process or to enhance synergy. Example: Musical greeting cards

Adapt: Which parts of the problem/product/process could be adapted to remove the probortunity or think how you could change the nature of it. 

Example: Snow tires

Modify: Changing part or all of the current situation, or to distort it in an unusual way. Example: All-you-can-eat restaurants

Put to Another Use: How you might be able to put your current solution/ product/process to other purposes, or think of what you could reuse from somewhere else in order to solve your own probortunity.
Example: De Beers put industrial diamonds to other use when they launched engagement rings.

Eliminate: What might happen if you eliminated various parts of the product/process/probortunity.
Example: Cordless telephone

Reverse: Think of what you would do if part of your probortunity/product/process worked in reverse or done in a different order.
Example: MacDonald’s rearranged the restaurant by getting customers to pay first and then eat.

Table 1.1 Chemical Devices Property Selection Table 

Criteria	Chemical Devices
	Heating Pack	Concave reflective mirror	Flameless Ration Heater
Thermal Energy Produced	Heat of hydration calculated for zeolite 3A is 220 J/g. Q = mass x heat of  hydration    =1000g x 220J/g    =220000J	A total power of 600 w is generated	76.812W A survey of flameless heating mechanisms revealed that a water activated electrochemical pad, composed of magnesium-iron alloy dispersed in plastic powders, would most effectively heat an 8 ounce entree. The FRH was tested and evaluated extensively to determine its technical and operational capabilities. The FRH is capable of raising the temperature of an entree from 40 degrees F to 140 degrees F in 12 minutes or less.
Portability	Heating pack is small and portable.	The parabolic cooker is somewhat portable.	Light weight
Sustainability	Zeolite is also reusable. It can be dehydrated after use and thus can be activated again to make it reusable.	Solar cookers made up entirely of reused materials would have negligible environmental impacts and costs. It also reduces environmental impact by up to 65%.	It can pose certain fire, explosion, and health-related safety issues.
Eco-friendly	Zeolite 3A is eco-friendly. Zeolite is completely recyclable.	It is eco-friendly as there is no carbon emission.	It is eco-friendly. It is non-toxic.

Table 1.2  Chemical Devices Selection Table 

Criteria	Weightages	Chemical Devices
		Heating Pack	Concave Reflective Mirror	Flameless Ration Heater
Thermal Energy Produced	30%	3	2	1
Portability	20%	2	1	3
Sustainability	25%	2	3	1
Eco-friendly	25%	3	2	1
Total	100%	255	205	140

In conclusion, we chose Heating Pack as our chemical device as it has the highest weightage for thermal energy produced and eco-friendliness out of the other 2 chemical devices. Even though Concave Reflective Mirrors have a higher weightage for sustainability, Heating Pack was still chosen over it as it has a better eco-friendliness as it is also important to take note of the impacts on the environment.

This week we learnt about S.C.A.M.P.E.R. With this method, we learnt that these questions help us to come up with creative ideas for developing new products, and for improving current ones. We also learnt something new and it's the feasibility analysis. We also had a good recap of the COW's Matrix as we had learnt it last year during our Materials Of Design Module. We hope that we will be available to learn more new things on the upcoming weeks.
