<aside> 💡 In Project 4, our team was tasked to develop a solution to improve the lives of two clients suffering from a disability. We decided to aid the client suffering from Secondary Progressive Multiple Sclerosis by creating a capacitive and ergonomic television remote.
</aside>
I made notes for both clients in order to help me come up with a solution.
Each team member came up with a unique solution. We performed a decision matrix to choose the best idea.
We ultimately chose the capacitive remote as the final solution due to its high score on the decision matrix and because it was the most creative and feasible idea
<aside> 🎯 Remotely control the television from far away
</aside>
<aside> 🎯 The Remote is functional with multiple devices of different brands
</aside>
<aside> 🎯 Minimize cost
</aside>
<aside> 🎯 Accessible and easy-to-press inputs
</aside>
<aside> 🎯 Accessible method of storing and retrieving the remote
</aside>
<aside> 🎯 Reduce the number of inputs required to perform an action

<aside> ⚖️ Must weigh less than 150 grams.
</aside>
<aside> 📏 Width must not exceed 7 cm
</aside>
<aside> 📏 Height must not exceed 3.5 cm
</aside>
After selecting the Capacitive remote, my team entrusted me with designing the CAD Model of our remote.
First Preliminary Model
<aside> ❌ The Electrical components could not fit inside the remote
</aside>
<aside> ❌ The cover could not securely close the back of the remote.
</aside>
<aside> ❌ Uncomfortable to hold due to sharp corners.
</aside>
Questions I asked myself.
Second Preliminary Model
<aside> ❌ Electrical components were still unable to fit inside.
</aside>
<aside> ❌ The print time is too long.
</aside>
<aside> ✅ The cover at the back of the remote successfully slides in from the side.
</aside>
<aside> ✅ Easier to hold due to the round corners.
</aside>
<aside> ❓ How can I optimize the remote's design to accommodate our dimensional constraints while ensuring adequate space for the electrical components?
</aside>
<aside> ❓ How can I reduce the print time?

The upper half of the Remote case
I created this part of the remote and then my modelling teammate modified it to fit his remote holder.
The Lower half of the Remote case
I designed the lower half as well. This lower is attached to the upper half using 3 mm x 15 mm wooden screws.
Remote Assembly
My teammate created a remote holder that attaches the remote to the client’s wheelchair.
<aside> ✅ Adequate space for the internal components.
</aside>
<aside> ✅ Since the Remote was divided into two parts, the print time was reduced.
</aside>
<aside> ✅ Remote can be placed onto the wheelchair using the remote holder.
</aside>
<aside> ✅ Large and accessible buttons
