Case 11: Sippy Cup Holder

Inspiration

For our project, we were inspired by the handwarming handle seen in certain mugs. More specifically, we were inspired by the circular indent where one could wrap their fingers inside to grab their mug. We also decided on a pink donut texture as a means of making the design more colorful and interesting upon viewing.

What it does

The cup holder itself has a handwarming handle where the recipient can place their fingers inside as a means to simulate grip strength without the need to grip onto an object. Attached to the cup holder is an arm brace with four slits. Through these slits, the design utilizes Velcro straps to wrap the product onto the recipient's arm, with the two sets of straps allowing for better stability when moving the arm.

How we built it

Using OnShape we split the cup holder and the arm brace into seperate parts via part studio. For the cup holder, we created the handwarming handle by sketching an arc, and then revolving the shape 90 degrees. With the arm brace, we designed two rows of slits where Velcro straps would rest inside, and we used the fillet tool to smoothen the edges to provide better comfort.

Challenges we ran into

One of the main challenges we ran into during our production was merging both the cup holder and the arm brace itself. Most notably, when aligning the arm brace, we noticed that it pierced through the cup holder. To resolve this, we sketched a circle above the brace, and extrude-removed the extraneous piece.

Accomplishments that we're proud of

The accomplishment we were most proud of was translating the handwarmer handle seen in special mugs into the design.

What we learned

Because we had to design a project for an actual patient on crunch time, we learned to brainstorm efficient and realistic ideas within limited timeframes. Moreover, this experience has greatly enhanced our knowledge of utilizing OnShape for 3D modeling, such as using the Revolve tool, Parts studio, etc.

What's next for Case 11: Sippy Cup Holder

Upon further consideration, we realize that despite the improved grip the prototype provides, the use of Velcro straps may serve as another roadblock when getting the patient to place their arm. As such, we will need to discover a more efficient solution towards stabilizing the patient's arm.
