Entering the Conceptual part of the project, each team is tasked with reassessing their strategies and breaking down to a concept using a Decision Matrix and different team visualizations.
Problem Statement
The purpose of the design is to aid in cleanliness and sanitation of common touch points when accessing entryways of any sort.
Assumptions about the Problem
- It is assumed that the device will prevent the spread of contact and airborne pathogens.
- It is assumed that the device can be maintained or utilized by proprietary owners such as corporate workers and/or private consumers.
- It is assumed that the device designs that require a power supply are placed at entryways with a secured outlet.
- It is assumed that the device will have interchangeable components if any piece were to reach failure and/or needs to be refilled.
Decision Matrix
Decision Matrix Reasoning
The appropriate percentages were allocated to each parameter for the importance they represent and in doing so we used the three different strategies we each individually came up with in the last part. Each parameter resonates an importance because each is considered through a different step of the process of it's use and the process as it is being manufactured. All of the concepts rely on a time based integrated sensor that releases a calculated amount per interval.
The first strategy conceptualizes a device that utilizes a bag replacement with a lid based interface with a simple lever mechanism with distributed force from the weight to make it manageable to be used easily. When approached there is a tab at the bottom that simply needs to be lifted to raise the front lid which is connected through a hinge at the back. Upon opening the system there is a bag with a small tip nozzle and that bag is interchangeable when it runs low or out of the disinfectant. Using the tab at an elongated distance allows less force to be used in the system as the resistant forces are more distributed, but it does present weak points in the system especially where the tab is connected and the hinge. Thus presenting as the most effective design in terms of usability.
In the second strategy, it is a mask that utilizes an auto adjustment system that is geared towards the rear of the system. From such would need high manufacturability and can have advanatges with mass distribution and use but would need to work on the durability for its frequent wear and tear. It is simple to manufacture and the use is very simple especially in times like this with the current pandemic. The faults mainly lie in the repairability and tolerability where it can fall apart and break relatively easy and would need a new unit to replace it. .
The third strategy is a rather simple and basic tmperature sensor that removes the human connection of having to check at every entrance. Because it is primarily run on electronics and sensory information it ranks relatively low on many of the matrix considerations but because motherboards and chips currently can be easily manufactured the cost of these remain fairly superior with high tolerability as there does not need to be continuous maintenance. The main problem is repairability and effectivenss since it is electrical components it can have issues in operating and can make repairs complex especially with multiple sensor and wire connections..

Lessons Learned
Some lessons I was able to learn and really hone go as follow:
- I've been able to further hone how to use a FRDPARRC Table and have little to no trouble going through one.
- Familiarizing myself with decision matrix as it has been a while since I last used one.
- How to really analyze and break down simple builds into complex systems with multiple machines.
- How to better prepare conceptual drawings to be informative and covering the principals that are followed.
