Safety and security were the two most crucial elements in my product and the two S's I focus most on in the creation of Svane and Sikker. In my final concept there is a total of five steps to lock the system. Two of these are on the Svane model to ensure the cat is locked into the pet carrier while the other three are on the Sikker model to lock the pet carrier to the bicycle. Each one of these steps are crucial for both user's safety.
step 1 - magnetic door
The top of the side doors each have a magnetic strip that connects to the closure. The magnetic closure and force that connects the door to the top of the carrier can be felt by the customer and gives them the reassurance the door is securely closed.
Step 2 - quadruple strap
Although the magnetic will initially lock the door shut, it will not be strong enough to stop the cat from escaping. I added double scraps on both side doors making the whole system a quadruple strap locking mechanism. In additional to ensuring the cat would not escape, my adding a strap that has to be physically fastened by the user makes them trust the lock rather than just relying on another system. This product psychology is important for a user who is concerned with the safety of their pet.
step 3 - t bolt slide
I used a T-bolt sliding mechanism so that when the base of Svane slides onto the Sikker system, the only way it can be taken off it slides out backwards. This makes it much easier for the user to fit the system on and will be secure once it is in place. On older designs, I used a straight design, however this could be easily removed by picking up the Svane carry case. The T-bolt locks the system in from both the side and the top making it very secure.
step 4 - housing
The housing, taking from inspiration from the front of a ski boot, locks the base in at one end, with the two teeth fitting into the cutout holes so they are in the correct position. Initially I was going to use clips at both ends but I because this end was under the bicycle seat this would be an issue for the user, making it near to impossible to clip and lock into place. I found one set of clips and a housing would give the same strength and security, but be a much easier system for the user to use.
step 5 - double clip and lock
Finally, as had chosen to place a housing on one end, the other side would need the clips. The clip and lock final step was inspired by a series of Tupperware boxes I experimented with in my research. One element I liked about these systems was not only the fact they worked and securely fastened the lid the box, but they gave me the reassuring 'click' noise that told me the box was securely closed. If I did not hear this noise, I was not convinced the Tupperware was closed. We find this a lot in the automotive market, with fabricated noises for the sound of a door closing being implemented to reassure the customer they have closed their car door properly. I wanted to reflect this same sensory signalling in my design on the final step as an audio reminder that their pet is safe and the carry case is firmly connected onto the bicycle.
In conclusion, for a product that is ensuring both safety and security, I think each one of these steps is crucial in earning the customers trust and ensuring them there pet is safe when using this system.
