Team Vision for System-Level Design PhaseOur 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 DecompositionFunctional 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.
Morphological ChartA morphological chart shows a breakdown of several solution options for each functional decomposition level.

Concept DevelopmentFrom the morphological chart, the team chose interesting concepts and researched each concept to compare which option is the most feasible for the customer.
Below are two possible visual representations created using some of the selected concepts.
Pugh Chart and Selection CriteriaA selection criteria was created based on what the bedside table has to do for the customer and stakeholders.
- Table will not tip over
- Can support loads as needed
- Fits under bed
- Easy to disinfect and clean
- No sharp edges
- Material costs stay within budget
- No gaps on the table top
- Can be integrated with the Industrial Design teams ideas
- Satisfies customer requirements
- Durable base
- Reduce the number of nurse calls
- Easy to maneuver
- Ergonomically correct
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:
- S: same a datum
- +: better than datum
- -: worse than datum
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.
