Table 1 properties of multifunctional exchange machine

Property Weight Justification cost 10 This machine will cost just some .money..
Safety 10 It’s very safe no one can steal the .money. in side without a noise.
Weight 5 it will be light machine for sure it’s very easy to carry
Reliability 3 It's not essential for our life, but it very useful device because it has many modern features
Power used 8 It will not consume energy at all
Convenience 7 The gadget ought to be helpful and simple to utilize. It has the suitable design and light material
Maintainability 9 The device is designed to be easy to carry, it has to be small and efficient
Compact Design 9 it’s small and easy to carry
Environmental Effects 10 It doesn’t pollute our environment at all
Aesthetics 10 The machine will have aesthetic side , it’s so important

1 = Weak, 10= Strong

Step 4: .Search .for .Solution:
We made some researches related to our project idea and researched on internet. We found some are available in the .market.. Some of them are more efficient but our idea is the cheapest at all. We will present some kinds of these as the

Firstly, our team defined the problem and identified the need as step1. We know that all people face many problems when they buy from any vending machine, they are not able to get their change back. This problem could lead them to ask for change , it’s embarrassing for some people to ask. So, we as engineers our duty is to solve problems as we can to make life easy and comfortable for people it’s our job. Our group discovered two conceivable alternatives to take care of this issue. The first one is invent a machine from iron because it will be a good electricity conductor and contains a sensor but it will be heavy to carry and it will be big. The second solution is a primary machine, made of cartoon easy to carry, good for environment and has sensor too, this is the only part that we will use electricity in. We as a gathering specify the correlation between the two choices in 'table 2' and we discovered and chose that the second arrangement is useful for individuals and more economy and basic than the alternative
