Through market research and analysis of competing products, I found that the extinguishing agent in the current market is single and not good enough for fire extinguishing work so I designed a three-in-one extinguisher with a three-tube structure as the main body. This allows people to make a simple choice when faced with a fire and to extinguish it efficiently. It also changes the original form of the fire extinguisher so that it draws attention to its position in life and gives an impression of its position in case of danger.

The 3-in-1 fire extinguisher is divided into 3 sections, the top handle is curved for hand-held operation and the curved structure is ergonomic, making it easier to operate. The bottle has three tubes in one, each containing one extinguishing agent in solid, liquid and gaseous form - carbon dioxide, dry powder and foam. The action can be switched by turning the handle on the top.
