Concept Sketches
|
Based on all the different sketches, the team wanted to create a wearable product for anyone that could be carried around easily. Combining the different features, we decided to incorporate the product into the idea of jewelry but also be attachable to other things. Our desired features concluded from our concept sketches were of a serrated blade, magnetic caps, an RFID chip, a sound alarm, and a handle grip. We also created design criteria to drive our future designs forward. These include making it wearable, easily accessible, modular, and aesthetically pleasing.

3D Iterations
First Iterations
Some of our first 3D designs consisted of an easy way to hold and grip onto the product with. We experimented with this idea and 3D printed it to test in hand. However, once we did this, we found that the grip wasn't very comfortable. We also found that if the handle existed, the design on the left would not be possible since it needs to swivel, which would cut the user's own hand. Moving forward, we decided to go with the right design consisting of a magnetic cap and fixed point.

Further Iterations
The first iterations of bringing our concept sketches to life gave us direction on what we wanted to improve. Here are a few more 3D iterations that we went through before the final design. We explored the possibility of a small base, a long base, a button, and a whistle. The button concept would trigger the sharp point to rise up. The whistle concept was thought to provide some type of audio alert for the user.

We ultimately decided to move forward with the long base concept. The base could double as a design for the entire product. The button concept fell through because we thought that the fixed point on the base itself would make the product quicker to use rather than require the need to press a button. The whistle also didn't move forward because of its need for being long and hollow, so it wouldn't be possible to incorporate it on the base of the sharp point. Instead, we thought of using an RFID chip in the product to provide an audio alert with the user's phone.
