Team Vision for System-Level Design Phase

Our Plan for the Systems Level Design Phase:

During the Systems Design Phase our team plans to take the problem defined by our customer and start to come up with different concepts on how to solve that problem. We will work together to identify different concepts that address the key functions of what the bedside table needs to do. We also plan on taking a tour of the hospital where the table will be used to ask key questions and collect data. By the end of this phase we plan to have our concepts selected so we can start simulating and creating prototypes for the next phase.

What We Actually Accomplished:

We were able to tour the Rochester General Hospital (RGH) and are in the process of scheduling a tour with Unity Hospital. During this phase, we defined key functions of the hospital bedside table and developed various concepts to address the different functions of the table. We selected a few interesting concepts to further research and consider the feasibility of the concept.

Functional Decomposition

Functional Decomposition is a chart showcasing what a product does for the customer. Below is the functional decomposition for a bedside table. It's main 2 functions are to provide surface area for the stakeholder (the patient) and to be movable from one location to another.

Concept Development

From the morphological chart, the team chose interesting concepts and researched each concept to compare which option is the most feasible for the customer.
Concept Selection

Below are two possible visual representations created using some of the selected concepts.

Pugh Chart and Selection Criteria

A selection criteria was created based on what the bedside table has to do for the customer and stakeholders.

Selection Criteria:

The Pugh chart is a chart comparing benchmarked ideas against criteria the project has to follow by in order to determine what is best. One of the benchmarked ideas is used a datum/reference to compare to the other benchmarked tables. Below are the different existing bedside table pro types and selection criteria.

There are 3 different symbols used throughout the Pugh Chart:

From the selection criteria, a Pugh Chart was created. The Industrial Team's current prototype was chosen as the datum to compare benchmarked tables against.
