Team Vision for System-Level Design PhaseGoals of the Phase:
- Break down the overall process of the Digitization
Process into all individual functions
- Determine all inputs and outputs of the system and functions
- Develop a list of all possible design concepts
- Select one design to move forward with based on a set of criteria important to the project itself
Define the total list of functions and subfunctions, based on the Customer and Engineering Requirements, that must be delivered by the final design.

Feasibility: Prototyping, Analysis, Simulation
Question 1: What is the average time of the proposed system, and what is the bottleneck?
- Load/Unload Times are the same
- Time at each step
- The system is constantly moving
Question 2: What is the motor's speed and torque required to move the camera up and down the camera?
- Camera Assembly: 5 lbs
- Pulley Diameter: 5 cm
- Vertical Height Change Speed Desired: 1 in per second
- Motor Runs continuously from start to end
Question 3: How much torque is required to move the conveyor belt?
- Diameter of Pulley: 7 cm
- Mass: 7 kg
- Coefficient of Friction: .3
Question 4: How much force is required to turn the knob on the back of the light?
- Potentiometer torque: 300 g-cm
- Diameter of Potentiometer = .6 cm
Question 5: How many GPIO are needed to adequately control the system?
Question 6: Can an automatic image crop program be integrated into CaptureOne with AppleScript?
- Automatic cropping will be done with an external script that returns the crop dimensions
- AppleScript can call shell scripts, so we will be able to access the script.
- We will have access to the RAW image after capture.
- RAW image is ~60 MB, might be time consuming to load in/decode
- Will need to return crop dimension to AppleScript
- We can set the crop dimensions for an image variant using the CaptureOne AppleScript dictionary.
- Shell scripts can return text to AppleScript (so we can return the crop dimensions)
Given the above, it should be very possible. Got a prototype working on Rahul’s laptop. It’s really slow and crops to the wrong rectangle, but it shows that it is possible.
Morphological Chart and Concept Selection
Analysis was used to explore all possible solutions to a multi-dimensional, non-quantified problem
PurposeGenerate new concept options or combinations that can potentially exceed the benchmark concepts

Risk AssessmentWe've made several additions to our risk assessments during this phase (seen in red below) :
Design Review MaterialsPlease see this pre-read that was created in preparation for the system design review on 10/11/18.
Plans for next phaseAs a team, we plan on having a single design ready to be developed. The team will work to use engineering to prove that the design can work on paper. Some items may be fabricated or ordered and preliminary testing may take place.
The next phase of the project involves the completion of several key tasks:
- Creation of a mock up for simulation purposes
- In-depth feasibility analysis, moving out of the past research stage and further into the future-state design
- A Bill of Materials that lays out in detail all of the necessary components for the purpose of final selection and budgeting
- Test plans that serve to define the degree to which engineering requirements are met
- Mitigation of risks that have been discovered thus far
