CAD Models

Moving onto technical updates, here is the design that we came up with.

We’ve designed a skincare dispenser that features 6 push buttons for 6 cartridges in a simple handheld shape.

The ergonomic sleeve is made out of silicone, making the experience of carrying the device around much more comfortable.The rest of the body and buttons are made out of plastic, housing 6 syringes. Each button uses a flexible shaft that we’ll show more in depth, but when its pressed, it pushes down a syringe plunger a specific distance, dispensing a consistent amount of skincare. Then, with a pen-like spring, it flexes and returns to its original position allowing you to press it over and over again. The whole design is split into two main bodies that can easily be taken apart to load and unload the syringes.

Housing Drop Test FEA Sim

Results

Maximum von-mises stress value is below UTS of ABS
Very minimal displacement (0.57mm)
Robust design against drop test cases

Mechanical Flexure FEA

Simulation Type: Static Deflection Analysis
Measure ability of mechanical flexure to withstand button pushing force (5.4 N)
Low max stress (3.2 MPa) resulting in FoS > 6
Low max displacement (15𝜇m)
