Team Vision for Detailed Design Phase

During this phase we hoped to be able to get the all of the component testing completed and have initial prototypes for testing in the NICU at the start of next semester. We are continuing to improve the documentation that we are presenting. We were also continuing to work on creating and improving the documentation of the project. We were able to get all of our materials in and complete testing for the individual fabrics and snaps.

Progress Report

At this time we have completed individual testing of the components going to the final product. The tests we ran were the ability of fabric to hold weight, the amount of stretch that each of the materials had, the amount of force required to pull apart the snaps and the usability of the snaps. With this information we will consider different options on how to use the materials together in the garment to get properties we want. Our customer Donna was kind enough to sew us two prototypes and we plan on using the prototypes to test at the NICU at the beginning of next semester. Some questions that still remain are what the processes are for UR Medicine Golisano Children's Hospital NICU in regards to testing the garment with parents and babies and getting our garment approved. We also will aim to get feedback from the customers on what they think of the fabrics and snaps we got and our plans for utilizing them in the garment.

Progress Report

Feasibility: Prototyping, Engineering Analysis, Simulation

During this phase, we started to complete the planned feasibility tests. All but one test was completed, and the remaining test is scheduled for completion by 01/23/2019.

The completed feasibility tests provided insight into the state of the current design and whether the prospective design elements will function as expected in an isolated environment. We tested the load bearing property of the fabrics to ensure that the materials could withstand significant weight at and beyond our safety margin. Additionally, material stretch was measured to determine the relative force-elongation relationship of the fabric, and a snap release strength test was conducted to test the normal tensile strength of the snap closure. Also, a snap usability study was conducted to determine user preference between our snap options.

Updates to Test Plans

Feasibility

At this point we have completed all but one of our planned feasibility tests. The remaining test is Parent Fabric Desirability. We plan to visit the UR Medicine Golisano Children's Hospital NICU at the beginning of MSD II (January 2019) to complete this test as soon as possible, which will entail parents trying on simple prototypes and evaluating material comfort.

System Level Tests

Below is the updated system level test plan. These tests will be performed during MSD II and applied to the garment as a whole. This test plan will be modified as needed in the remainder of MSD I and throughout MSD II.
