Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Cleared and finalized possible design proposals and alternatives to previous team's final prototype.
Discussed possible testing strategies using the gel test articles.
Began some CADing using previous team's final model on SolidWorks.
Added a funnel system for the microneedling array.
Accomplishments from Previous Week
Team meeting with Dr. Dobke discussing new aims and priorities for this quarter.
Explored on possible ways to move forward with optimization with the current model that we have from the previous quarter.
Discussed alternative models and how we can have the needles move back and forth with the funnel system idea.
Presented our Design Proposal presentation to the class and instructor.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Meet with both sponsors if possible.
Show updated CAD design with funnel system for feedback and approval.
Hand sketch some possible solutions on how the needles can move back and forth given the updated model.
Conduct any needed literature reviews on how we can incorporate better movement for needles.
Discuss more ideas and alternatives on better developments and design solutions to solve problems that took place on the last team's prototype.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
See if instructor approves of new plan and objectives for project.
Instructor agreed to our new project scope based on our design proposal presentation.
Figure out the budget required for any alternative plans.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Figure out testing strategies using gel test articles that were recently received.
Focus on how we can optimize the current team’s prototype through simulation and provide alternative designs.
Explore design alternatives for needle platform and the axial mobility of the micro-needles.
Think about possible optimizations for the current model: Creating a needle grid on Silicone, have a hollow storage tank to separate from the driving mechanism for the grid.
Provide more engineering analysis and thoughts when making design decisions.

N/A
Risks and Areas of Concern
Have not been able to meet with Dr. Duncan but consistently meetings with Dr. Dobke
Difficult to meet with everyone in person.
Do not have lab access so anything physical needs to be potentially done at home.
Current prototype:
Structure or materials of needles may deform/break during injection.
Optimize size of current cartridge
Agent delivery system does not work as a whole
Energy could impact conditions of the injected agent.
Resources or Information Required but not Available
Everything must be done virtually with the team.
Schedule
