This is one of our simplest designs. In terms of pricing, it would be a fairly cheap option. It would be small and fairly easy to construct. It would require no programming seeing as though it would not require any electrical components. It would also not require batteries. What really brought down the score on the decision matrix was this designs ability to stay within the temperature range. While it has premium insulation, with the temperature range of NARCAN, a heating system will probably be required.
This design by far was our simplest, unfortunately it was a little too simple. With only insulation, the container would not be able to maintain the warmth needed to keep the temperature constant.
Originally, we were planning on having the container both heat and cool the NARCAN. After further research, we found that cooling systems are very complex, expensive, and wouldn't be easily accessible. Aside from that, we would have to program both heating and cooling systems. It would also take up much more battery life.
We found this solution to be the most efficient. We found that with a vacuum seal, we would be able to maintain a constant temperature without a cooling system. A heating system although would still be mandatory to compensate for the .cold Minnesota winters. It would also require less programming and would save battery life. Overall, this was the best solution we had come up with.
