Integrated System Build & Test

Team Vision for Integrated System Build & Test Phase

During this phase, the group wanted to get as much of the mechanical and electrical build completed in order to move forward with testing. Ideally the group would've completed the integrated system build and move forward with final testing, but spring break and other obstacles stood in the way. The group also wanted to work on documentation, more so for the final paper and the poster which will be needed in early April.

As mentioned, the group dealt with obstacles that included needing to order new parts. A new humidifier, dehumidifier and other electrical components were purchased again. The electrical build was put on hold as new parts needed to arrive and will resume as parts come in. The mechanical build is nearly complete with the exterior being formed around the cnc cut molds. The group has also been working on the technical write up as well as the mock poster in order to receive peer feedback before Imagine RIT.

Test Results Summary

The test plans can be accessed throughout the EDGE website in a live document and will be updated throughout the semester. No further test plans have been copleted since last review. All test plans are in the excel template except for the sanitation and ergonomics. The ergonomics testing has been completed, but due to the variety of requirements testing within the ergonomics test, the plans were not put into the excel format.

Detailed documentation of test plans were created in order to fully understand the procedure without needing to follow the flow charts in the excel document.

Screenshots of the completed battery and ambient temperature sensor are seen below.

Risk and Problem Tracking

Rick Assessment

Purpose
The Failure Mode Effects Analysis (FMEA) allows for an in depth evaluation of any potential risks during the use of the product. When evaluating risks, a cause and effect are assigned in order to determine the root of the issue and define countermeasures to lower the potential occurrence.
Updated Assessment Overview
The document owner is Victoria Tripp.

Problem Tracking

Thus far, no risks have manifested as problems, but if needed the template of the problem tracker can be found here.

Functional Demo Materials

For the remainder of the course, all review material will be presented through the team EDGE website along with any physically built components and testing results. No extra materials were needed for this phase review.

Plans for next phase

For the next review at ImagineRIT, the team plans to have a functioning prototype, poster, and documentation. The electrical build is now able to be completed as missing and needed components have arrived from purchasing. The electrical build will plan to include the heating components, humidifier, and dehumidifier components. The build already includes a heat and humidity sensor, digital output screen, audible buzzer, and fan. The mechanical build is near complete with the completed molds, and once heat formed will allow for final testing and the integration of the mechanical and electrical builds. Finals tests to be completed before ImagineRIT include the heat, humidity, and sanitation.

As individuals on the team, final deliverables have been made by team members whereas a list of semester deliverables have been made for the electrical engineering team members. The electrical engineering semester list is now up to date, with completed items crossed off the list. The progress will be determined by the ease of build or further complications that may arise wile also keeping the deadline in mind. The document can be found here

Job Gantt

An updated job gantt for the semester can be seen below. The job gantt has estimated due dates for each task which are likely to change based on when components are received as well as incorporating any build and testing issues that may arise. A live job gantt can be found here.
