Design me a Product - Parking Entry Manager

Hi.

I'm looking for an engineer to design a product I have in mind. The product is a parking lot entry system. In other words, we can assume that an entry boom to the parking lot already exists and this system will be installed next to a current ticket dispenser. So this is a third party unit which only deals with identity confirmation. The unit is a box type unit.

The system will work with an RFID or NFC chip (depending on which has a lower price) and when a user entering a parking lot places his/her card near the system, the system then communicates with an online (in other words, an internet connection of some sort is needed) database to see whether the given user has access to that boom. If the user does have access, the system will command the entry boom to open. The same happens with exit.

Problems the system might face would include (not limited to):

- communication with the boom (e.g. are all entry booms easy to command via third party access like this?)

- Internet connection: Since this would fetch data from an online database, we would need a reliable internet connection. Thoughts: An optional UTP cable connection with a mandatory backup system which uses mobile data to connect to the internet.

In other words, since this system has the potential to be installed in any site (even on sites where ADSL or other forms of cable connections do not exist), the system will still be able to communicate with the database via mobile data. This will lead to the system requiring a possible SIM card slot. Problem: Say the parking site is underground without an internet access point, the Cellular data would also be useless due to lacking signal.

-Effective speed of the system: Since we can assume we are in a crowded parking area, we do not want the system to take exceptionally long to communicate with the database. A thought on a solution might be to download the database partially onto the system once per day, and when a user swipes his/her card, the system would then create an update queue. The update queue contains a list of users whom have swiped to gain entry, and would then (Hourly) update the database with the data stored in the queue. Which leads to the requirement for a storage bank in the system.

-power supply: It can be assumed that the site will have access to power, but the system also requires a backup power source in case of power failure (ONLY IF: the boom has a backup power supply. I'm not sure how to check for that). The system will have an access point for a (conventional) power supply. The backup system will be charged by the primary power supply. Since this only powers the system itself, I don't believe a huge reserve is needed (Unless communication with the boom requires excessive amounts of power).

-Installation of the system: the system should be encased in a rugged, weather proof encasing (E.g. Hard plastic or any suitable, inexpensive alternative). The encasing will have openings on the base to securely bolt the unit to the floor.

(The outer encasing must be visually appealing)

-Display: an inexpensive display should be used. (E.G. LCD screen)

REQUIREMENTS:

A DEGREE in some form of Engineering (From a reputable university).

The product will be used to apply for a patent so without an international degree, I cannot submit your design.

-English should preferably be your home language.

-I need a PCB layout designed.

-Your task is to fully complete the design so that it can easily be manufactured from your design.

-Identification of further pitfalls. If you can see any other problems the system might incur, please mention it.

-Cost breakdown and cost minimisation.

-(CAD) rendering of the product.

IMPORTANT

Please provide me with an estimated cost for the design of the product when submitting your bid! Submissions without this requirement will not be considered!

Make sure you understand what the unit's capabilities should be and that you have the skills to complete the entire design efficiently.
