Possible/ Final Solutions Reflection

I am very happy with the door locking mechanism that I have designed for this project. I think my possible solutions were great for cementing in my mind what was important to consider in the final design, these considerations included:

1. Must not jam
2. Must be discreet
3. Must be as secure as it can be to keep the elderly person and their belongings safe
4. Must include a key so that the elderly person does not have to adapt as much from their habits developed over their entire lives.

I think that this design could be very successful and could be integrated into today's doors quite easily.
