Our goal is to satisfy the demand for an innovative medical device that can provide a comprehensive first aid remedy for superficial wounds along with a user-friendly design for people who may lack clinical experience. The SprAid will become a universal tool in the sense of convenience, cost efficiency, durability and reliability to the everyday worker and household family for use in clinical settings, outdoors and at home care. In order to design such system the means to achieve the functions must comply with our objectives and constraints. First, we developed a ranking scale from 1-10, as shown in the Ranking Scale. A rating of a 1 is poor, a 5 is neutral, and a 10 is excellent. Ratings between 1 and 5 for a function are considered negative because they show low adherence to our set objectives and constraints. On the other hand, ratings between 5 and 10 for a function are considered positive because they show high adherence to our set objectives and constraints. As shown in the Weighted Scale, we also employed a weighted scale to determine which objectives and constraints were more critical to achieve our desired goals for SprAid. The chosen function for the Evaluation Matrix was to Differentiate Between the Three Therapeutic Solutions. The means to achieve this function was to use a three-port manifold with independent valve switches made out of aluminum material. As it can be observed in from the evaluation in the Ranking Scale, the three-port manifold with independent valve switches got a total score of 131 out 140 points, which satisfies 94% of the objectives and constraints. After performing a weighted average in the Weighted Scale, the new score of 622/640 shows that the three-port manifold with independent valve switches actually satisfies 97% of the objectives and constraints.
