Solution Development

Group Design Tasks:

To collect data on how home break-ins occur to find what the most unsecure part of the home is.

To gauge how consumers feel about door unlocking and locking convenience.

To research the prices of materials and development of products.

To do research on smart home devices.

Final Solution Attributes: Convenience and Security

Paths:

1. An app-controlled video doorbell that can be switched on or off, and can alert the authorities if a door is opened without disabling the doorbell alert system first.

• Easier to install than other options and more cost-effective than replacing the doorbell.

• Alert system can scare off intruders and call authorities to respond to potential break-ins.

• Inconvenience of having to turn off the alarm

2. A modern electronic doorbell system that requires a digital changing key rather than a static physical key.

• Changing the digital key is more secure and less convenient than a static physical key.

• The installation process has the potential to be costly.

3. Keypad door lock that has pin code input.

• Code can be potentially replicated and accessed even without physical key.

• Installation process can be costly, and inconvenient.

• Can't be lockpicked like traditional locks

4. Biometric scanner doorbell(i.e. Fingerprint or Handprint scanner)

• Very high quality at keeping a house secure.

• Very costly

• Potentially very excessive amount of security compared to the rest of a normal suburban house.

Design Goals:

• The most important part of our project is security.

  • Without proper security, the other features wouldn't matter there would be no adoptions of the product.

• The goal of our project is to create a convenient method of entering properties.

  • There also needs to be extra features to convince people to adopt the new method

Design Specifications:

• Must be easy to install

• Must be cost-efficient

• Must be convenient to use

• Must provide more security than the standard method

The Final Solution

Paths:

1. The first path seems very complicated and harder to use than what our design goals want.

2. The second path meets all of our design goals and specifications.

3. The third path fails to meet the cost-efficiency and security specifications.

4. The fourth past fails to meet the cost-efficiency design specification

The Final Path:

The group decided to go with the design of the second path as we found that it meets most of our design specifications.
