JIEUN

• Deadline for sheet metal: On the outside, can be gathered last (2024 Al) (3-4 mm)

• Fabric: next steps?

  • Originally have Lovisa if she can go to Ethan & Allen

RENZO

• Got a 3D printer over the weekend

  • can prototype stuff at home

• Assembly plans are coming along

  • Working in parallel with Battery box (Micah black)

  • Just the outer fibreglass stuff for now

• Kristen is planning to purchase soon (click bonds, MDF, and mold stuff)

• Start researching MDF CNC

IVAN

• Finish manufacturing plan by October 31st

  • Still catching up on lectures rn

FABRICS (Jieun)

• Lovisa to look at Ethan Allan offline store

• Confirmed concept & fabrics

  • Just need to figure out where to get it from

• Sheila to give new members tasks

FORM FACTOR (Renzo)

• MDF 20mm thick sheets ✅

  • sheets to be cut down after purchase

    • From forestproducts

• Brackets for supplier interfacing

• Click bonds to be supplied through Kristen?

  • Need part names + quantities

• 3D print started for testing

• Manufacturing can begin when MDF is delivered

• To update BOM

MATERIALS (Ivan)

• Can't use Nomex

  • New foam = Divynice HM80 foam (PVC foam)

    • Sourced from Composites Canada

• Epoxy resin

  • Amount needed ✅

  • No specific product

  • Aeropoxy PR2032

• Need mold release

• Ask Min for sealant tape

Updates:

Finalized all materials needed - urethane foam (fibreglass foam core) and epoxy resin.

Message Micah Black about the seal… waiting for a reply.

“Marking” is different from “seal”

Ivan’s break is at 8:30-9:00 pm

Next Steps:

Manufacturing plan for molds.

Updates:

Covers for latches - reduce collision with batteries (made if 3D Printing, attached with epoxy)

Added support grid under the base

Added structural ribbing along the edges of the enclosure (epoxy on)

Connection port - 3 inputs, leave a blank slot for now, as we are not sure which ports to model

Seal? - No reply from email, will ask Micah before Thursday.

Will lay off of front design, don’t want to conflict with dashboard

Fabric - Made group chat with Testing DRI’s to search for fabrics together! Researched cleanliness (hydrophobic/antimicrobial coating or a fabric protector) and padding (sponge foam roll/roll tiles).

3D Printing - fast drying polyurethane with spray paint

Next steps:

Renzo - Create a general list of materials to use and amount. Then send list to Kristen.

How are we feeling?

Ivan- will continue looking for tomorrow or Thursday

Will attempt FEA again. Lookup formulas for thickness testing. Can try without simulations. Get it done by the end of this week.

Renzo - tweaking rear electronics, and redesign the shape for the exterior.

Needs ballpark for material specs.

Jieun - ask Ivan to hand over some research to her. Adrian mentioned looking at the aesthetics and seal.

Renzo → research mounting hardware: bushing, fasteners, click-bonds, etc. no space under the chassis tubes.

Schedule changes

New meeting times

Tuesdays @ 2:00 pm - Ivan, Jieun, Daphne

Tuesdays @ 7:00 pm - Renzo, Jieun, Daphne

Wednesday @ 9:00 pm - Renzo, Jieun, Daphne

Thursday @ 2:00 pm - Ivan, Jieun, Daphne

Thursday @ 7:00 pm - Renzo, Jieun, Daphne

Saturday @ 1:00pm - Whole team

How are we feeling?

Renzo - Good, we’re pretty ahead. The catamaran is very self-contained (☞ﾟヮﾟ)☞☜(ﾟヮﾟ☜).

Ivan - Pretty good, just to confirm stuff with stakeholders and is good.

Jieun - Needs some more direction.

How are we fastening the cover onto the catamaran?

Relay fastening over to Ivan.

3M double-sided industrial used, epoxy, etc. Do some research on adhesives that may be combined with a hardware fastener.

#1 - latch to take the lid off (this is the one Renzo is doing)

#2- mounting it onto the chassis (this is the one Ivan is doing)

Testing and validation for Jieun

We can’t really do a roll-over test right now. Testing will definitely have a more significant role later.

Materials/Manufacturing

Ivan does not need to find the manufacturer himself (that’s for Supplier Interfacing). He does need to document and organize what the Supplier Interfacing team and the machining companies need to know for the cover.

Concepting

Waiting for Adrian for front vent, latching for the lid, space behind the rear electronics (can we reduce the cover for aesthetics? or will it interfere with airflow?)

The cover extends over the chassis tubes so we need a double-check on that.

Proposal Planning

DRI will do their own thing while follow our “key things” we plan to discuss during the meeting.

Hopefully we can have everyone for the meeting on Thursday night

Design Phase meeting?

Either during the stakeholder meeting or after the stakeholders.

Questions:

• Where are we making our own slides?

  • we’ll make our deck for now.

we also learned that Ivan and Daphne’s (19 yay) bdays are really close so we’re planning a bring-your-own-drink online party for Aug. 15th at 9:00pm. If you’re reading this, you are secretly invited to that party (●'◡'●)
