This design stems from the shocking discovery of how many people die unnoticed in their homes each year. Some remaining undiscovered for almost a year. I didn't want to tiptoe around this. I wanted to design for these people. Not to save them from death but to save them from an unnoticed one.
My final outcome was a product that would weigh the amount of post that came through a persons door and was left unopened. When it reached a certain weight, after a certain time, the letterbox would jam and alert the outside world (or at least the postman).
This is an instruction kit I designed as a continuation of this project that illustrates how the user might make their own model. I chose to deal with this sensitive subject in an overly practical way. This created a strong contrast that might highlight this issue that shouldn't be occurring in such a communication obsessed culture.
