Alex is an individual who lives alone in a house and travels frequently for business and pleasure. Alex owns various valuables that are stores inside the house. While traveling, a thief often breaks into the house and steals some of the valuables.

To stop the thief Alex brings several Dogs to the house for protection. The Dogs' barking scares the thief and prevents burglary.

PROBLEM

The dogs must be purchased, trained, and fed. Also, pet sitters are needed to visit the dogs when Alex is away. The dogs are an expensive solution for Alex. Alex is looking for a less expensive solution to protect the valuables.

APPROACH

Formulate a TRIZ model to help identify the adequate actions, the excessive/inadequate actions, and the harmful actions. In the context of the above problem (i.e., no departure from the scenario), offer a solution using any combination of the following TRIZ principles:

2 - Take Out

6 - Universality

24 - Intermediary

26 - Copying

ANSWER

PROBLEM FORMULATION - Use the TRIZ problem formulation approach. Indicate object (O), tool (T), auxiliary tool (AT), and primary function (PF) in the model. Provide a legend for the different action types.

HARMFUL ACTIONS or CONFLICTS - As identified in the problem formulation.

SOLUTION - Reference the TRIZ principle(s) used when describing your solution.
