As we approach the end of the term, we would like to define our criteria for evaluating our concept to see if it is achieving the desired outcomes.
First, our design must be modular. The complexity of the device must be compartmentalized. If we can achieve this, then our users will have a much greater degree of ownership over the technology than over comparable devices in our domain. Our end users will be able to fundamentally understand the functionality of the EKG from the ground up. Additionally, they will be able to modify the design to best fit their specific situation and repair the device should any problems occur.
This leads to the next design criterion of making problems visible. If a modular component should fail, then our end users (doctors and nurses) should be able to identify what went wrong. Either by thermochromic paint or by electrical indicators, there needs to be an unambiguous sign that shows where the problem is happening so that the proper repair can be made.
The ultimate design must also efficiently use resources and must be able to be produced fairly easily. Cost parameters should be minimized while making sure that the components of our EKG device can be manufactured in bulk.
