Does the solution to an engineering problem have to address every need of its users? Explain your answer.

No, but it should address a large proportion of the problem

Explanation:

In solving an engineering problem, there are so many variable to consider. If all the variables are to be considered simultaneously, the problem will become more complex. To solve most problems, an engineer must try to solve as much of the problem possible, without sacrificing other properties or variables of the problem. An example is a refrigerating system, which is designed for an environmentalist summer camp. The refrigerating system will be used to cool down drinks, and probably to make ice for the campers. A lot of problem associated with using a refrigerator includes 1. the heating up of the external environment due to the heat rejected from the refrigeration compartment, and heat generated by the working components of the system. 2. Refrigerants are not ozone friendly. 3. The risk of electric shock. 4. energy consumption.

The engineer in this case will have to solve the most pressing of problems which is cooling. Ozone degradation, electrical consumption, and heating up of the surrounding environment can be reduced to a minimum, and the electric circuitry would be covered as much as possible, but this does not address all the possible need of the user.
